Please note the revision history in the front section of the manual and check the Exalt website download section to verify the most recent firmware release available for your product.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 21 2007-01-03 This manual uses terminology to distinguish the characteristics of specific radio models. The term standard refers to the EX-2.4i, EX-4.9i and EX-5i models. The term -16 refers to the EX-2.4i-16 and EX-5i-16 models. When no specific mention is made or the term i-Series is used, this refers to all models. Generally, the i-Series models require a clear line-of-sight and proper path clearance to achieve a high-performance, reliable connection. Perform professional path engineering and site planning BEFORE installing this equipment. The primary focus of this document is the installation and maintenance of the digital microwave radio, and assumes that path engineering and site planning has already been performed. Please refer to the Exalt document, Guidance for Engineering and Site Planning of Terrestrial Wireless Links, for detailed information on these activities. The EX-2.4i models utilize radio frequencies in the range of 2400 to 2483.5MHz. The EX-5i models utilize radio frequencies in the range of 5250 to 5850 MHz. In most countries these frequency bands are considered as ‘license-exempt’ or ‘unlicensed.’ This means that virtually any user may use these frequencies freely, without paying for access, or any type of pre-notification, post-notification or registration. As a result of this designation, users may also move or change these systems at any time, with significant flexibility to the location, orientation and configuration of the system. However, due also to this designation, there may be uncontrolled interference from other similar devices that occupy this spectrum. In these cases, it is up to engineering and maintenance personnel to design the system with existing and future interference sources in mind, recognizing that there is a chance that the interference conditions could be very dynamic, and outages may occur on the system as a result, and that, in some very rare cases, the system may cause interference into another system and may be required to be disengaged or modified/re-oriented to eliminate the interference. If the spectrum in your country is designated as ‘license-exempt’ or similar, this does not infer that the installer may configure the system in any manner at any location. In most cases, there are regulations, or device-based conditions that limit the use of the device, such as maximum gain antenna, antenna types and maximum output power, as well as, in some cases, application limits, limited geography of use, and other unique regulations. The link design engineer and/or professional installer must determine these limitations and engineer/install the system within the confines of all local regulations. Also, it is required to examine any regulations that may apply to peripheral equipment, installation and cabling of the system that may be regulated for human safety, electrical code, air-traffic control, and other safety-related categories. In certain countries, the spectrum for this product is NOT considered to be license-exempt. In these cases, there may be additional regulatory requirements concerning the location, frequency, power, orientation, configuration, and other aspects of the system, including, in some cases, a need for link registration, coordination, and fees that may apply to the system usage. Please consult your local regulatory organization(s) to determine usage requirements.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 22 2007-01-03 The EX-4.9i utilizes frequencies in the 4940-4990MHz range, and is typically a licensed band reserved for use by Public Safety agencies and applications. This band is not generally available outside of North America. In almost all cases, either for license-exempt or other designation, the product itself must be authorized for use in your country. Either Exalt or Exalt’s agent must have applied for certification or authorization to allow the sale and deployment of the system within the country. It is also possible that only certain versions or configurations of the device are allowed within a particular country. Please contact Exalt or your authorized Exalt representative for information pertaining to your country. It is the professional installer’s responsibility to ensure that the radio system is implemented in a legal fashion. Exalt is not liable for any unsafe or illegal installations. Basic Features The i-Series Digital Microwave Radios are single integrated units intended for all-indoor or enclosure-based mounting. The associated antenna is typically mounted on a tower or rooftop mast structure with RF cabling running from the antenna location, with an egress through the structure or enclosure, with proper lightning suppression and grounding, to the RF connector of the radio. In turn, the communications interfaces and power connections are directly applied to the radio, or in some cases, also with an egress through the structure or radio enclosure with proper lightning or surge-suppression devices and associated grounding.

Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 23 2007-01-03 Figure 3 Enclosure mount interconnection For highest performance and reliability, it is advised to minimize the length of RF cable and associated transmission system losses between the antenna and the radio’s antenna port. All models provide connections for a combination of the following data communication interfaces: • 10/100BaseT Ethernet • Up to 16xT1/E1 interfaces for synchronous voice traffic (number of TDM interfaces is determined by specific model and license-key configuration) The i-Series radios feature a wide-mouth direct DC connection (24V or 48V), and are also provided with an external AC adapter. All models provide the following primary features and benefits: • Low-latency optimization and control for voice and data connections • Very high throughput and flexible interface configurations with voice+data combinations • Encryption for extreme wireless security • Easy-to-use management and configuration • Flexible utilized channel bandwidth selection for interference avoidance and frequency coordination • Flexible center frequency tuning for interference avoidance and frequency coordination • Flexible capacity to meet current connection requirements and future growth needs • Carrier-class reliability and performance STRUCTURE PENETRATIONRF LIGHTNING ARRESTOR (GROUNDED) RADIOGROUNDED POWER/DATA/INTERFACESLIGHTNING ARRESTOR(S)POWER/DATA/INTERFACESPOWER/DATA/INTERFACESANTENNACABINET

Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 25 2007-01-03 Pre-installation Tasks This section describes the steps necessary to prepare a site for the installation of the Exalt Digital Microwave Radio. Link Engineering and Site Planning Design all terrestrial wireless links prior to purchase and installation. Generally, professional wireless engineering personnel are engaged to determine the viability and requirements for a well-engineered link to meet the users’ needs for performance and reliability. The reader is referred to the Exalt document, Guidance for Engineering and Site Planning of Terrestrial Wireless Links and the ExaltCalc path calculator. This document and calculator aid in the pre-planning and engineering required to determine following attributes: • Antenna type/gain at each end of the link • Antenna mounting height/location for proper path clearance • Antenna polarization orientation • RF cabling type, length, connectors, route, and mounting • Antenna system grounding • Lightning arrestor type(s), location(s), and grounding • Radio mounting location and mechanisms • Radio grounding • Radio transmitter output power setting • Anticipated received signal level (RSL) at each end • Anticipated fade margin and availability performance at each end • Radio settings for TDD frame length and occupied bandwidth • Anticipated throughput performance (TDM circuit support and Ethernet) • Anticipated system latency With respect to radio path and site planning, these radios are generally identical to any other microwave terrestrial wireless systems. Engineering of these systems requires specific knowledge about the radios, including: • RF specifications (transmitter output power, receiver threshold, occupied channel bandwidth, and carrier-to-interference tolerance) • Regulatory limitations on transmitter output power setting and antenna type/gain • Noise/interference profile for the intended location
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 26 2007-01-03 • Impact on throughput and latency relative to link distance, occupied bandwidth, and TDD frame size setting, and the planned implementation of these parameters Familiarization with i-Series Radios The i-Series radios utilize time division duplex (TDD) radio transmission. This means that the transmitted signal in both directions uses the same center frequency and transmits in one direction for a period of time, and then in the opposite direction for another period of time. This total period of time is referred to as the frame length or TDD frame length, and is further discussed in Time Division Duplex (TDD) Factors on page 33. The two radio terminals are identical hardware, except for the TDD setting in software. When the radios are in their default state, both radios are configured as Radio B. One end of the link must be configured as Radio A before the two ends of the radio system can communicate. It can be considered that Radio A is the primary radio in the link. Radio A provides the master clock and control to Radio B. For most applications, it is not important how the radio link is oriented, only that one end is configured for Radio A and the other for Radio B. For some applications (such as, multi-radio hub sites or repeaters), the orientation of the radio systems may be more critical. See Link Orientation and Synchronization on page 34 for details. There are three ways to configure the radios for Radio A/B determination: 1. Use the Exalt browser-based graphical user interface (GUI) – preferred. 2. Use the temporary hardware configuration key, in case of emergency (all models except for -16 models). 3. Use the front panel DIP switch, in case of emergency (-16 models only). Exalt recommends using the Exalt GUI for radio configuration. This interface requires a computer with an Ethernet port and web browser software, such as Microsoft Internet Explorer 5.0 or above. See Configuration and Management on page 62 for details on how to connect to and use the browser-based GUI interface. Standard models: The temporary hardware configuration key can be used when no computer is available to complete Radio A/Radio B configuration and there is a need for immediate bench testing or initial link installation and/or antenna alignment. See Radio A/B Configuration on page 34 for details on the temporary hardware configuration key. -16 models: The front panel DIP switch provides a fast temporary means for Radio A/Radio B configuration. See DIP Switch Settings (-16 Models Only) on page 124 for details.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 27 2007-01-03 Shipping Box Contents Unless purchased as a spare terminal, the radios are shipped as a complete hop (that is, a radio link pair consisting of two terminals). An outer box has labeling that indicates the contents of the box, with the part number and serial number details for both radio terminals. Inside the outer box are two identical boxes, each of these boxes is also marked with the part number and serial number of the individual terminal contained inside the box. The terminal box contains the following items: • Radio terminal (configured as Radio B) • AC adapter • Accessory kit ¶ Rack mount flanges ¶ Flange mounting hardware (4 x M4 screws; 4 x M4 wave washers) ¶ DC power connector (1) ¶ Temporary hardware configuration key (1 x 9-pin connector, labeled “A”) ¶ Grounding hardware (1 x M5 screw; 1 x M5 wave washer; 2 x M5 flat washers) ¶ Radio A temporary hardware configuration key (for standard models only) • Registration card • Quick-start guide Inspect the outer packaging and the contents of the boxes upon receipt. If you suspect any shipping damage or issues with the contents, contact Exalt Customer Care. Register your system as soon as possible.

Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 28 2007-01-03 Back-to-Back Bench Test and Configuration Every Exalt digital microwave radio goes through extensive quality testing and performance evaluation over the full operating temperature range prior to shipment. However, before installation, it is strongly advised to perform several tests and tasks that are much more difficult to perform once the radio link endpoints are distant from one another. A back-to-back bench test and pre-configuration will provide confidence that the radio link is operational and properly configured prior to installation, so that if troubleshooting is necessary, the radio hardware and configuration settings are eliminated from the troubleshooting process. Verify the following in the back-to-back testing: • Confirm that the radio system is generally operational ¶ Radios power-up with planned power and wiring solutions ¶ RF link connects in both directions ¶ Traffic passes across the link • Configure connected equipment and cabling ¶ Test Ethernet (CAT5) cabling, and/or T1/E1 cabling, any auxiliary connector cabling and configure all interfaces ¶ Configure IP settings for configuration and management ¶ Configure passwords and security modes ¶ Become familiar with the configuration and management interfaces through the Exalt GUI interface • Configure radio parameters ¶ Set transmitter output power to engineered or allowed level (see RF Output Power Setting on page 29) ¶ Set operating center frequency ¶ Set link distance, occupied channel bandwidth, and frame length • Make detailed radio performance measurements ¶ Measure transmitter output power ¶ Measure receiver threshold performance ¶ Confirm unfaded error-free performance Some of these tasks may not be possible or practical within a bench test environment due to the nature of the remote connectivity of peripheral equipment. However, it is good practice to perform as much as possible in this environment to minimize field/installation time and troubleshooting efforts.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 29 2007-01-03 Detailed performance measurements are usually not required for pre-installation, but can be easily performed at this stage and may be helpful for later troubleshooting efforts or for internal records. During troubleshooting, there may often be a point at which a back-to-back bench test should be performed to verify many or all of the above items, and in the case of a suspected faulty device, to help confirm the fault and determine which end of the system is at fault and in need of repair or replacement. See Back-to-back Bench Testing on page 114 for detailed instructions. RF Output Power Setting The maximum RF output power is bounded by one of the following criteria: • Maximum RF output power setting capability of the radio device • Maximum RF output power allowed/authorized by the local government regulations and for this specific device • Maximum effective isotropic radiated power (EIRP) of the transmission system allowed/authorized by the local government regulations and for this specific device • Desired RSL to not exceed the maximum RSL allowed by the device • Desired RSL to minimize/eliminate interference into neighboring systems In many cases the radio must be pre-configured for legal maximum output power before connecting to the antenna and transmission system. Instructions for adjusting the output power can also be found in System Configuration Page on page 74. The following information pertains to specific regulatory requirements based on up-to-date information for countries where these radios are authorized. A list of recommended antennas is listed in Antenna/Transmission System on page 53. United States Compliance The EX-2.4i and EX-5i families operate under FCC Rule Parts 15.247 and/or 15.407 as a license-exempt device. The EX-4.9i operates under FCC Rule Part 90 as a licensed device. All of these devices must be professionally installed. They may only be used as a point-to-point transmission device for fixed or temporary-fixed (non-mobile) installations. The devices are subject to the following restrictions: • Do not use external amplifiers to boost the power or overcome transmission system losses, unless the specific amplifier/cable/antenna combination has expressly been authorized by the FCC. The output power must never exceed +30dBm. • Cross-border transmissions are expressly prohibited, except with written permission from both the FCC and the governing body of the neighboring country (Cofetel for Mexico; Industry Canada for Canada).
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 30 2007-01-03 • Use only parabolic dish antennas or directional flat-panel antennas. No other types of antennas (omni-directional, yagi, and so on) are authorized. Parabolic dishes of either grid or solid type are allowed. Maximum mid-band gain of each type of antenna certified is: ¶ EX-2.4i models: – Parabolic dish: 30.3 dBi (6'/1.8m diameter) – Directional flat panel: 20.5 dBi (~2'/61cm square) ¶ EX-4.9i models: – Parabolic dish: 26dBi (larger gains are allowed, with Tx power reduction) – Directional flat panel: 26 dBi (larger gains are allowed, with Tx power reduction) ¶ EX-5i models: – Parabolic dish: 37.9 dBi (6'/1.8m diameter) – Directional flat panel: 28 dBi (~2'/61cm square) EX-2.4i FCC (USA) EIRP For the EX-2.4i models, maximum transmit power with respect to FCC (USA) EIRP regulations is determined using the following equation: P = 30 - [(G - 6)/3] + L where: P = Maximum transmitter output power of radio, in dBm G = Specified gain of antenna, in dBi, from 2400 to 2483.5 MHz L = Total transmission system losses of all elements between the radio’s RF connector and the antenna’s RF connector (all cables, connectors, and lightning suppressors), in dB, as specified or measured between 2400 and 2483.5MHz The maximum EIRP allowed for the EX-2.4i models is 52.2dBm. The maximum output power of the radio shall never exceed +30dBm. The professional installer is responsible to ensure that RF output power is properly adjusted to not exceed the regulatory limit of these conditions. EX-4.9i FCC (USA) EIRP For the EX-4.9i model, within the 4940–4990 MHz band, the maximum EIRP allowed is +50dBm. The maximum output power of the radio shall never exceed +24dBm.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 31 2007-01-03 For the EX-4.9i models, the transmit power must be reduced from maximum (+24dBm for 20MHz BW, +22dBm for 10MHz) by 1 dB for every 1dB that the antenna gain exceeds 26dBi (including transmission system losses). The professional installer is responsible to ensure that RF output power is properly adjusted so that it does not exceed the regulatory limit of these conditions. EX-5i FCC (USA) EIRP For the EX-5i models, within the 5725–5850 MHz band, the maximum EIRP allowed is 61.9dBm. The maximum output power of the radio shall never exceed +24dBm. For the EX-5i models, within the 5250–5350 MHz band, the maximum transmit power with respect to FCC (USA) EIRP regulations is determined using the following equation: P = 30 – G + L where: P = Maximum transmitter output power of radio, in dBm G = Specified gain of antenna, in dBi, from 5250 to 5350 MHz L = Total transmission system losses of all elements between the radio’s RF connector and the antenna’s RF connector (all cables, connectors, lightning suppressors), in dB, as specified or measured between 5250 and 5350 MHz For the 5250–5350 MHz band, the maximum EIRP allowed for this device is 30dBm. The maximum output power of the radio shall never exceed +13dBm. The professional installer is responsible to ensure that RF output power is properly adjusted so that it does not exceed the regulatory limit of these conditions. Canada Compliance The EX-2.4i and EX-5i models operate under RSS-210 of Industry Canada regulations. The EX-4.9i model operates under RSS-211 of Industry Canada regulations. Operation is subject to the following conditions, unless express permission is granted by Industry Canada to operate in a different manner: • External amplifiers cannot be used to boost the power or to overcome transmission system losses, unless the specific amplifier/cable/antenna combination is expressly authorized by Industry Canada. • Cross-border transmissions are expressly prohibited, except with written permission from both Industry Canada and the governing body of the neighboring country (FCC for USA) • Only parabolic dish antennas or directional flat-panel antennas may be used. No other types of antennas (omni-directional, yagi, and so on) are authorized. Parabolic dishes

EX-2.4i IC (Canada) EIRP For the EX-2.4i models, maximum transmit power (Pmax) with respect to Industry Canada EIRP regulations is unlimited. The output power shall never exceed +30dBm. EX-4.9i IC (Canada) EIRP For the EX-4.9i model, within the 4940–4990 MHz band, the maximum EIRP allowed is +50dBm. The maximum output power of the radio shall never exceed +24dBm. For the EX-4.9i models, the transmit power must be reduced from maximum (+24dBm for 20MHz BW, +22dBm for 10MHz) by 1 dB for every 1dB that the antenna gain exceeds 26dBi (including transmission system losses). The professional installer is responsible to ensure that RF output power is properly adjusted so that it does not exceed the regulatory limit of these conditions. EX-5i IC (Canada) EIRP For the EX-5i models, within the 5725–5850 MHz band, the maximum EIRP allowed is 61.9dBm. The maximum output power of the radio shall never exceed +24dBm. For the EX-5i models, within the 5250–5350 MHz band, the maximum transmit power with respect to IC (Canada) EIRP regulations is determined using the following equation: P = 30 – G + L where: P = Maximum transmitter output power of radio, in dBm G = Specified gain of antenna, in dBi, from 5250 to 5350 MHz
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 33 2007-01-03 L = Total transmission system losses of all elements between the radio’s RF connector and the antenna’s RF connector (all cables, connectors, lightning suppressors), in dB, as specified or measured between 5250 and 5350 MHz For the 5250–5350 MHz band, the maximum EIRP allowed for this device is 30dBm. The maximum output power of the radio shall never exceed +13dBm. The professional installer is responsible to ensure that RF output power is properly adjusted so that it does not exceed the regulatory limit of these conditions. Time Division Duplex (TDD) Factors The i-Series radios are very dynamic, allowing the installer to optimize and control the performance of the radio system for the intended application. The following parameters must be carefully determined during the link engineering phase: • Link distance • Bandwidth • TDD frame size • Mode (modulation) The setting of the above parameters determines the following performance factors: • Number of supported T1/E1 channels • Ethernet throughput • System latency (delay) Use the ExaltCalc calculator to determine optimum settings for the above parameters to meet the needs of your application. The following generalizations can be made with regards to these factors: • The shorter the TDD frame size, the lower the latency • The shorter the link distance, the lower the latency, the higher the throughput • The longer the TDD frame size, the higher the throughput • The higher the bandwidth, the higher the capacity • The higher the mode, the higher the capacity Disable all T1/E1 ports if there are no T1/E1 interfaces connected. This shifts all available throughput to the Ethernet interface. If a selected combination of the Link Distance, Frame Size, Bandwidth, and Mode parameters cannot support all the desired T1 or E1 ports, the ports that cannot be supported are automatically disabled. Priority is placed on the T1/E1 port number. That is, the first port to be disabled, if
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 34 2007-01-03 necessary, is the highest port number, such as Port 4 for the standard models, and Port 16 for ‘-16’ models (assuming that all 16 TDM interfaces are licensed for use). See T1/E1 Configuration Pages on page 79 for more information. Link Orientation and Synchronization Link orientation refers to the Radio A and Radio B placement in your network. Link synchronization refers to using external or internal timing to coordinate multiple links. For every link, one end of the radio link must be configured as Radio A, while the other end is configured as Radio B. In single-link systems, it does not matter which end of the system is mounted at which end of the link, and there is typically no requirement for any link synchronization. Link orientation and synchronization are more important for networks with site(s) where there is more than one link of the same type or for sites using the same type of radio that are very close to each another at one or both ends. It can be advantageous to utilize link synchronization for collocated links. The radios allow the use of an optional GPS synchronization kit or internal synchronization. This synchronization controls the transmitter and receiver frame timing so that collocated radios are transmitting at the same time and receiving at the same time. This can substantially reduce the opportunity for self-interference. Without synchronization, collocated radios may be transmitting and receiving at the same time, incurring near-end interference. It is not always necessary to synchronize collocated radios. If antennas are substantially separated or blocked from one another and/or frequency separation tuning is used, the opportunity for near-end interference can be eliminated. Internal and/or GPS sync features are not released for all models as of printing. Contact your Exalt Communications representative for details. Radio A/B Configuration Use the Exalt GUI to configure the radio terminals for Radio A and Radio B orientation. Since many other parameters also need to be set, and the Exalt GUI is needed for these configurations, this is the best way to completely configure the radio terminals. Radios arrive from manufacture in default configuration, orientated as Radio B and configured as shown in Table 3.

In many cases, the system design will not be identical to the factory default configuration, and in some cases, these differences prohibit the installation of the radio. If at all possible, obtain a computer and configure the radio terminals using the browser-based GUI. See Exalt Graphical User Interface (GUI) on page 64 for details. Temporary Hardware Configuration Key (Standard Models Only) Use the following steps to enable the temporary hardware configuration key: 1. Remove power from the radio. 2. Remove anything connected to the ALARMS port. 3. Connect the key (found in the accessory kit) to the ALARMS port. 4. Hold down RMT button while applying power. The LEDs toggle through the boot cycle.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 36 2007-01-03 Continue to hold the RMT button until the LEDs stabilize (approximately 45 seconds). 5. Release the RMT button. The following configurations are reset on the radio: • IP address = 10.0.0.1 • IP mask = 255.0.0.0 • IP gateway = 0.0.0.0 • Administration password = password • User password = password • Endpoint Identifier = Radio A DIP Switch Configuration (-16 Models Only) The -16 models have a DIP switch to allow temporary configuration for Radio A and Radio B. See DIP Switch Settings (-16 Models Only) on page 124 for information on DIP switch functions. Radio Synchronization The radio synchronization feature improves the performance of Exalt radios operating in the same frequency band and that are collocated (such as in repeater and hub configurations). Radio synchronization ties radio systems together to operate off of a common clock system, ensuring that all radios simultaneously transmit and receive, and thus eliminating near-field interference issues and related radio system coupling. The synchronization function is not currently available on all Exalt radio models. A firmware upgrade may be required for models without sync if sync is desired. Contact your Exalt representative for details. Synchronization Modes Synchronization can be accomplished using either an internal or external source. In either case, one radio in the network must be defined as the primary sync source (A) radio. A Global Positioning System (GPS) kit from Exalt is required to implement external source synchronization. GPS synchronization is not available on all radio models. Contact your Exalt representative for details. Synchronization implementation only requires one synchronization source for any interconnected network. The system also implements a redundancy configuration to maintain a majority of the synchronization functions in case of primary radio failure.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 37 2007-01-03 For internal synchronization, the primary radio is designated SYNC SOURCE. This radio provides the master timing for all interconnected radios. SYNC SOURCE radios and collocated radios must be configured as Radio A. Collocated radios must be in SYNC RECIPIENT mode; they receive sync signaling from the SYNC SOURCE, either directly or daisy-chained with other collocated radios. Alternatively, the radio(s) can be placed in AUTO SYNC mode. AUTO SYNC synchronizes the radios to any source provided on the SYNC IN port. However, if an appropriate synchronization signal is unavailable, the radio becomes the SYNC SOURCE for all connected radios. Internal Synchronization Figure 4 illustrates the basic interconnectivity of a radio system using internal synchronization. In this scenario, there are two radios collocated at one site. Figure 4 Basic radio interconnectivity using internal synchronization In Figure 5, there are three collocated radios. In this configuration it may be desirable to make one radio a secondary sync source using AUTO SYNC. This provides redundancy if the primary sync source radio (A) loses power or experiences any other failure. Figure 5 Collocated radios, one in AUTO SYNC mode to provide redundancy The synchronization function can be carried across links to additional collocation sites. For example, Figure 6 illustrates a multi-link backbone with two hub sites. SYNC SOURCE (A) SYNC OUT FAR-END RADIO (B) FAR-END RADIO (B) AUTO SYNC (A) SYNC IN SYNC OUT SYNC RECIPIENT (A) SYNC IN FAR-END RADIO (B) SYNC SOURCE (A) SYNC RECIPIENT (A) SYNCOUT SYNC IN FAR-END RADIO (B) FAR-END RADIO (B)
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 38 2007-01-03 Figure 6 Multiple-link site configuration, using AUTO SYNC for redundancy The configuration shown in Figure 6 is not supported in all models at the time of this writing. Consult your Exalt representative for details. Virtually any combination of hubs and repeater sites, star configurations, and/or backbones can be implemented with synchronization using these configurations. It is typically necessary or ideal in each configuration to match the following parameters on every radio in the network: • Link Distance – Match to the longest distance link in the network. • Frame Length – Match to the lowest frame length to optimize total system latency (for example, for TDM networks) or match to a highest frame length to optimize user throughput. Choose an intermediate value to compromise between latency and throughput. • Mode – It is desirable, but not always necessary, to match the mode for all collocated links. • Bandwidth – It is desirable, but not always necessary, to match the bandwidth for all collocated links. For complex networks, an Exalt engineer should review multi-link networks before deployment as several factors can optimize the network for desired performance. External Synchronization Use an external GPS source as an alternative to the internal synchronization source for system synchronization. This is ideal for links that are nearby each other, but are not directly collocated at the same site. Figure 7 illustrates using a GPS source for the primary synchronization at a typical site with collated radios.

Exalt i-Series Installation and Management Guide 5000001 39 2007-01-03 Figure 7 GPS as primary sync source using AUTO SYNC Figure 8 illustrates two separate radio locations benefiting from synchronized GPS sources. Figure 8 Synchronized GPS sources using AUTO SYNC Offset Timing Manual control of offset timing is also allowed. This provides a means to delay the synchronization signal using a user-defined offset. This is helpful when Exalt radios are near other devices operating in the same frequency band that also use a timing source, such as GPS. The timing source to the Exalt radios can be adjusted to match the other radio system timing source mechanism. Offset timing can also optimize timing intervals for repeaters and backbones. As the distance of each link results in a unique factor for speed-of-light transmission of the radio signal, a subsequent radio can be delayed in timing so that the overall synchronization of radios is precisely maintained. Offset timing can be adjusted in 1-ms intervals, from zero to the radio’s frame length setting. For example, if using a 2-ms frame length, the offset timing can be set from zero up to 1999 ms.

Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 40 2007-01-03 Offset timing is not supported in all models at the time of this writing. Consult your Exalt representative for details. When Sync is Lost If the primary sync source (for example, the sync source radio or GPS source) signal is lost due to equipment failure, a disconnected sync cable, or other conditions, the first radio in the daisy-chain configuration set to AUTO SYNC resumes the sync function for the remaining connected radios. If a radio is configured as SYNC RECIPIENT, transmission ceases if the sync signal does not appear at the SYNC IN connector. A radio running in AUTO SYNC (without the sync source) is said to be flywheeling. That is, the clock is free-running off internal clocking and is no longer synchronized to any source. If the original sync source is restored to the flywheeling radio configuration, the flywheeling radio attempts to synchronize to this signal without causing transmission interruption. All interconnected radios receiving sync from the flywheeling radio also continue to operate without interruption. When the flywheeling radio runs independently for long periods of time, the synchronization signal can be too far outside of the capture range of the synchronization loop, and portions of transmission frames can be lost during the re-synchronization process. This condition is temporary and all interconnected radios re-synchronize to the sync source, as necessary. For GPS synchronization, the wiring inside the Exalt radio carries the GPS signal to the next radio cabled in the system, even when power is removed from the SYNC SOURCE radio or during radio failures. This provides redundancy for catastrophic failure of the SYNC SOURCE and maintains GPS synchronization. If the GPS source is lost (for example, due to failure of the GPS unit, a disconnected cable, or satellite blockage), the AUTO SYNC radio resumes synchronization duties for all collocated radios. LEDs There are two LEDs on both the SYNC OUT and SYNC IN ports. Table 5 on page 47 describes the two SYNC IN and two SYNC OUT LEDs.

Keep a record for each end of the radio link and store a copy of these records at the radio location, at the opposite end radio location, and a central record storage location. • GPS coordinates for antenna locations at each site • Antenna heights above ground level (AGL), as mounted • Antenna model numbers, serial numbers, and specifications • Antenna polarization as mounted • Length/type of primary transmission lines at each site • Model number and serial number of RF lightning arrestors • Length/type of secondary transmission line(s) • Transmitter output power setting as installed at each site • RSL as measured after antenna alignment at each site • Designed RSL per original design at each site • RSL reading with far-end power off (from each end) • Spectrum analyzer plot with far end off at each site • Voltage standing wave ratio (VSWR)/return loss at radio’s antenna connector at each site • Radio’s network management IP address at each site • Radio’s network management gateway address at each site • Radio’s operating frequency, bandwidth setting, and mode of operation • Optionally purchased extended warranty and/or emergency service contract details In addition, certain information may be desired for central record-keeping only: • Security codes and login passwords (kept in a secure place) • Photographs of complete installation • End-user sign-off/acceptance documentation (if any) • Photo of rear panel label (part number, serial number, MAC address information) • Site access information phone numbers, access codes, directions
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 43 2007-01-03 Installation This section presents all tasks required to install the Exalt Digital Microwave Radio. Mechanical Configuration and Mounting The i-Series radios are one-piece radio designs intended for deployment in a telecom equipment rack indoors or in an appropriate environmental enclosure. The device must be deployed within an ambient temperature range as specified, and properly ventilated with no obstructions to the air intake and exhaust. The standard models occupy 1 rack unit (1RU = 1.75”/4.5cm ) height in a typical telecom rack. The -16 models occupy 1.5 RU (2.625”/6.7cm). In most cases, additional racked equipment can be placed directly above and/or below the device with no empty spaces in the rack. However, depending on power consumption and ventilation for adjoining devices, they may pass heat to the device, not allowing the radio to cool properly and increasing the risk of malfunction. Heat dissipation from the radio may also affect adjoining devices. Provide air space above and below the device, where possible. If not possible, a thermal analysis may be required by a professional engineer to determine the impact of thermal transfer between all adjoining units. Provide proper clearance for all cables and connectors attached to the device. Notably, the RF cable connector may require significant clearance for the bend radius of the coaxial cable assembly. Use a properly specified 90º RF connector to minimize clearance requirements, which may be necessary in enclosure implementations. All RF connectors, cables, and adapters must be rated for operation within the radio’s frequency range (2400–2483.5 MHz for EX-2.4i; 4940-4990 MHz for EX-4.9i; 5250–5850 MHz for EX-5i). RF connector losses must be accounted for within the link engineering design and output power settings. Rack Mounting Rack mounting hardware for a standard 19" (48cm) rack is included in the accessory kit. Attach the rack mounting brackets to the sides of the unit with the provided screws. The radio can be mounted in one of four configurations: • Front flush mount (front panel even with the rack mounting surface) Figure 10 Front flush mount configuration
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 44 2007-01-03 • Front projection mount (front panel extended forward from the rack mounting surface) Figure 11 Front projection mount configuration • Rear flush mount (rear panel even with the rack mounting surface) • Rear projection mount (rear panel extended forward from the rack mounting surface) Figure 12 Rear-mount locations The rack mounting brackets accommodate identical mounting configurations as shown in the previous figures, and can be mounted three different ways with respect to the vertical orientation in the rack: 1. Projecting down, using one full rack space and half of the space below, and leaving a half-space gap below. 2. Projecting up, using one full rack space and half of the space above, and leaving a half-space gap above. 3. Centered within two spaces, with ¼ rack space gap above and below. Two radios mounted in the same rack can be mounted in adjoining spaces, utilizing a total of three rack spaces. Screws for attaching the radio to the telecom rack are not provided; use the appropriate screw type that matches the equipment rack. USE THESE BRACKET-MOUNTING HOLES FOR REAR-FLUSH OR REAR-PROJECTION MOUNTING
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 45 2007-01-03 Table or Rack Shelf Mounting the System Affix rubber feet or adhesive-backed non-slip pads (not included) near the corners of the unit along the bottom panel when mounting on a table or a rack shelf. These pads help keep the radio stable on a wooden or metal surface. In many areas, it is necessary to strap the equipment to a table or rack shelf if mounting in this manner. In case of earthquake or other shock or vibration, or an accidental pull of a cable, the unit should be secured from falling. It may also be necessary to secure the AC adapter, if it is used. Radio Ports and Indicators This section provides a brief overview of the connectors, controls, and indicators on the device. Details about each item are in other sections of this document. The EX-2.4i front panel is shown in Figure 13. The EX-4.9i and EX-5i front panels are identical, except for the model number shown in the upper-right corner.

Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 49 2007-01-03 RMT (Remote) Button The RMT button is the only external control on the radios. This button allows easy and quick evaluation of the status of the remote-end radio. Press and hold the button and, while held, all local-end status LEDs (LINK, STATUS, Radio A) represent the status of the LEDs on the remote-end radio. In addition, the RSL voltage represents the remote-end voltage. When the RMT LED is amber flashes, this is an alert that the remote end has an alarm condition. Press the RMT button to determine the alarm conditions. When the RMT button is pressed and held and local LEDs flash, this indicates that no remote-end information is available. This indicates that the remote radio is either not powered, is booting, or is not linked in the direction towards the local radio, or the local radio is receiving excessive errors in this direction. It could also indicate a serious failure of either radio. Local-end LEDs (when this button is not pressed) in combination with remote-end information (from a technician located at the far end, and/or when the button is pressed) can substantially aid in rapid troubleshooting analysis. Power The radio requires a DC power source within specifications. The DC can be provided from a DC battery source, central lab/rack supply, or from the supplied AC adapter. Read this section completely before applying power. Terminating the RF Connector Before applying power, the device’s RF connector must be properly terminated into a 50-Ohm load. If this is not performed, the radio may be damaged by simply applying power. Also, there are human safety factors to consider regarding potentially harmful RF radiation. There are a few simple means to accommodate proper termination: • Connect a 50-Ohm coaxial termination device to the RF port of the radio. The termination must be rated to 1W (or more). Example(s) include: ¶ Broadwave Technologies P/N 552-200-002, or similar • Connect the complete transmission system. That is, the RF cabling including the antenna. The cabled antenna provides a proper termination for the RF output.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 50 2007-01-03 • Connect a fixed (or a series of fixed) 50-Ohm attenuator(s) to the RF connector, either directly or at the end of an RF transmission line. The attenuator must be at least 30dB as specified at the operating frequency (~2400 MHz for the EX-2.4i; ~4950 MHz for the EX-4.9i, ~5700 MHz for the EX-5i), and rated for a minimum of 1W input power. Examples include: ¶ Broadwave Technologies P/N 352-103-xxx ¶ Bird 2-A-MFN-xx ¶ JFW Industries 50FP-xxx-H6-N AC Power The AC adapter easily connects to the device. The AC rating of the adapter accepts most standard voltages and frequencies worldwide. Refer to the input voltage requirements stated on the label affixed to the adapter to ensure that the adapter can be used with the AC mains supply. The AC plug outlet provided with the adapter may need to be replaced to match the country configuration. The adapter cable uses a standard connector for this cable for use of a pre-wired cable appropriate to the outlet configuration. If the appropriate cable is not available, the existing AC plug end can be severed and a replacement plug affixed. Consult a qualified electrician for this activity. Do not plug the adapter into the mains power. First, verify that the RF connector is properly terminated (see Power on page 49), and then plug in the radio-side connector from the AC adapter to the radio. If the AC mains can be turned off using a switch, disable the power, plug the AC side of the adapter into the AC mains socket, and then enable power to the circuit. If the AC mains cannot be turned off, plug in to the AC main socket to apply power. Verify that the radio is active by observing LED activity. All LEDs on the radio flash at initial power cycle. It is strongly encouraged that the AC mains supply be fused or on a separate breaker to ensure against over-voltage and/or over-current situations and to provide some form of protection to the radio electronics and other devices connected to the same supply. In addition, if the AC power is subject to significant spikes or variation, power conditioning is a worthwhile investment, as the quality of mains power may have a direct impact on the device operation, performance and/or reliability. An Uninterruptible Power Source (UPS) or other form of battery-backed system protects against brown-out and black-out conditions, and condition the power presented to the adapter. Evaluate the opportunity for lightning or other similar surges to be present on the powering system, including the ability for surges to couple to the power wiring system. If an evaluation indicates that there is a potential likelihood for these conditions to occur, additional surge protection is recommended for the input power wiring, especially to protect the radio electronics between the adapter and the radio’s DC input connector. The above statement is similarly true for every wired connection to the device. While the configuration for surge suppression or line conditioning is of a different type for each
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 51 2007-01-03 kind of signal interface, the opportunity for damage to the device, loss of communications and property is significant. In some cases, there can also be a risk to human life by not protecting against lightning entering a building through wiring or improper grounding. If you do not have experience in this type of installation practice, consult a qualified electrician and/or telecoms professional during the installation and wiring of the equipment. DC Power The device accepts DC power within the voltage specifications. The DC voltage input accepts either 24 volts or 48 volts, nominal. Ensure that the power source is specified for the proper amount of current delivery capacity. The DC power may be connected as a positive or negative voltage supply, and be referenced to ground or ‘floating’ (differential voltage). There are different system grounding considerations depending on the nature of the DC supply grounding, and consult a qualified electrician or telecoms professional on the proper wiring and grounding process. To connect a DC source, with the power disabled on the DC supply, connect proper gauge wiring to the DC supply. For most (short) power cable runs, 18AWG or 24AWG wire can be typically used. Strip the ends just long enough for enclosure to the DC radio connector (approximately 0.25 inches/6mm). If using stranded wire, the stripped ends inserted into the DC terminal connector must be solder-tipped. If using solid wire, a solder tip is not necessary. Ensure that the power wiring is long enough to neatly traverse, when properly dressed, between the source supply and the radio mounting location. If DC wires are to be exposed to outdoor environments, use wire in the proper weatherproof wiring jacket. For longer runs of DC wiring, use a higher gauge wire and/or higher current source supply to overcome the additional resistance of the DC wiring. However, the DC connector for the radio may not be able to accept a high diameter wire, transition to thinner gauge near the end of the wiring run or use the maximum diameter wire for the entire wiring run, as long as it meets the powering requirements considering total resistance of the wiring and the power source current load capacity. Insert the wiring ends into the DC mating connector (supplied) and tighten the terminal screws to secure the wire into the connector. Do not connect the mating connector to the radio system and disable the power system. Pay close attention to the polarization of the DC signals coming from the DC supply and the ground conductor (if any), and ensure that they are connected to the proper pins of the DC mating connector. The connector mate on the radio is clearly marked on the front panel for proper polarization and for ground connection. Wire across the plus (+) and minus (-) terminals from the DC supply. In addition, place a separate jumper between the proper terminal and the ground terminal to reference one side of the power supply line to the radio chassis ground. In some cases, the DC system may need to be floating and this ground jumper is not necessary; however, many configurations require one side to be grounded for proper electrical safety.

Exalt i-Series Installation and Management Guide 5000001 52 2007-01-03 Consult a qualified electrician if uncertain about how to properly ground the system and connect power. Figure 16 DC connector Once the wires are connected to the mating connector, do not connect to the radio. First test the DC connection to the connector from the DC supply. Engage power on the DC supply, and use a volt meter to verify proper voltage level and polarity. Verify that the RF connector is properly terminated, as described in Terminating the RF Connector on page 49. Disengage power once again on the DC source, and connect the mating connector to the radio device. Engage power on the DC source. Verify radio is active by observing LED activity. All LEDs flash during the initial power cycle to verify that they are operational. Secure the DC connector using the integral captive screws at each end. This prevents accidental disconnection. See Power on page 49 regarding fusing, breakers, lightning protection, surge protection and power conditioning. Follow these recommendations for a DC supply. Reset to Critical Factory Settings If necessary, the radio terminal may be reset to critical factory settings. This may be necessary if the IP address and/or passwords for the system are not known. All other configurations are left at their current settings. If a complete default factory configuration is desired, load the Default Configuration File into the system, as described in System Configuration Page on page 74. The following parameters are configured after a reset to critical factory settings: • IP Address = 10.0.0.1 • IP Mask = 255.0.0.0 • IP Gateway = 0.0.0.0 • Administration password = password • User password = password • Endpoint Identifier = Radio B (unless temporary hardware configuration key is installed on a standard model, or the DIP switch is used on a -16 model) To perform a reset to critical factory settings: 1. Remove power. 2. Remove connections to the ALARMS port. !

Mount the antenna at the proper height, mast/mounting location and polarization orientation as determined by the path and site planning engineer(s). The model type, location, and orientation of the antenna is critical with respect to achieving proper path clearance, as well as to mitigate external or self-interference from nearby or collocated systems operating in or near the same frequency band. Mount the antenna in a restricted area and in a manner preventing long-term human exposure to the transmitted RF energy. To comply with FCC and Industry Canada regulations, the minimum safe distance from the antenna for continuous human exposure for the EX-2.4i models is 10 feet (3m), 39 inches (1m) for the EX-4.9i, and 10.5 feet (3.2m) for the EX-5i models. !
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 56 2007-01-03 The antenna structure must be secure and safe with respect to the mounting of the antenna, transmission system weight, and the combined weight of any personnel that may climb or attach to the structure. The combined weight of items and forces on the structure must be carefully considered in the design and construction of the structure. This must include the weight bearing on the structure in the highest wind conditions possible in the region, and with respect to all objects affixed to the structure. If additional objects are affixed to the structure in the future, it may be important to evaluate both the mechanical impact of these planned additions (with respect to wind and weight loading), as well as the potential impact to RF interference and frequency coordination (if additional radio equipment is anticipated). This is especially important if future equipment is likely to operate within the same frequency band. Once the antenna is mounted, cabled, and aligned, your goal is to never require modification. This prior planning is important in the path and site planning stages and in construction of the antenna structure. Follow the antenna manufacturer’s instructions for mechanical mounting of the antenna. Ensure that there is enough room around the antenna for alignment activities (moving the antenna in vertical and horizontal arcs), and for the RF transmission line to connect to the antenna connector unobstructed and within the specified bend radius requirements of the transmission line. At this point, the antenna mounts should be fully secure to the structure, the feed of the antenna securely mounted to the antenna (if the feed is a separate assembly), and the azimuth and elevation adjustments not completely tightened in preparation of the antenna alignment activity. It is a good practice to connect the transmission line to the antenna connector as early in the process as possible, to reduce the opportunity for debris or moisture to enter either the antenna connector or the transmission line connector. Use a connector cover or other temporary measures to ensure that the connector is kept clear. Take extra care if the antenna is installed during inclement weather to ensure that no moisture gets inside the antenna connector at any time. Now the antenna can be aimed in the general direction required for the link. Use a compass, a reference bearing, binoculars or any other similar device to point the antenna in the direction (generally) of the far end radio, and then slightly tighten the azimuth and elevation adjustments so that the antenna maintains its general position and is safe to be left without additional securing. Refer to the Exalt white paper, Antenna Alignment, for more information on antenna alignment techniques. Transmission Line from Antenna to Egress Most installations use coaxial transmission line for the connection between the antenna and the radio device. Coaxial transmission line can either have a solid or braided shield. Solid-shield cables are more resistant to external signal coupling and interference, but are generally stiffer than braided cables. Consult the path or site engineer(s) to ensure that the proper materials are chosen for the installation and that all factors were considered. Refer to the Exalt white paper, Transmission Line for Exalt Indoor Radio Systems. Generally, the larger the diameter of the transmission line, the lower the loss. So for longer runs of transmission line, larger diameter cables are highly advised. However, at
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 57 2007-01-03 every frequency, there is a maximum diameter cable that supports the operating frequency. Verify the specifications. This should is determined in the path and site planning process. In some cases, the choice of transmission line is not coaxial cable, but is instead air-dielectric waveguide. This is an expensive solution and is generally not necessary, but may be required for very long transmission line runs, and/or very long link distances, and/or for systems requiring extremely high reliability. Table 8 lists representative samples of transmission line types recommended for the Exalt Digital Microwave Radio. Table 8 Recommended transmission line Manufacturer Type Description Loss at 2.4GHz Loss at 4.9GHz Loss at 5.3GHz Loss at 5.8GHz Andrew LDF4-50 1/2-inch solid shield 3.3dB/100ft. 5.6dB/100ft. 5.7dB/100ft. 6.0dB/100ft.Andrew LDF4.5-50 5/8-inch solid shield 2.5dB/100ft. 4.3dB/100ft. 4.4dB/100ft. 4.7dB/100ft.Times LMR-600 1/2-inch braided shield 4.3dB/100ft. 6.8dB/100ft. 6.9dB/100ft. 7.3dB/100ft.Times LMR-900 5/8-inch braided shield 2.9dB/100ft. 4.5dB/100ft. 4.6dB/100ft. 4.9dB/100ft.RFS LCF12-50J 1/2-inch solid shield 3.5dB/100ft. 5.5dB/100ft. 5.6dB/100ft. 5.9dB/100ft.RFS LCF12-58J 5/8-inch solid shield 2.8dB/100ft. 4.4dB/100ft. 4.5dB/100ft. 4.8dB/100ft.There are several other brands and models of transmission line that are perfectly acceptable. However, for extremely long transmission lines and/or extremely long radio paths, it may be necessary to use waveguide transmission line instead of coaxial transmission line. In these cases, waveguide type EW20 is recommended for EX-2.4i models (0.45dB/100ft. loss at 2.4GHz), and type EW52 for the EX-4.9i and EX-5i models (1.2dB/100ft. loss at 5.8GHz, 1.35dB/100ft. loss at 5.3GHz). It is critical that the transmission line and antenna be capable of supporting the same type of connector, or easily adapted. It can be important to minimize the number of connectors and adapters, and it is ideal that they match directly without adaptation. In most cases, transmission line allows for N-type male connectors and antennas have N-type female connectors. For waveguide, the waveguide flange can typically accommodate a direct adapter to an N connector, or alternatively, the antenna can be purchased with a direct waveguide connection. But often a flexible coaxial jumper is required to connect between the waveguide and antenna, as waveguide is generally inflexible and can be mechanically challenging to align to the exact antenna connector location. If possible, connect the primary transmission line directly to the antenna. It is desired to have the fewest possible pieces of transmission line in the system, to minimize losses and points of failure from connectors. The antenna can typically accommodate a direct connection if planned in advance. Use a 90ºadapter for the connection to the antenna, if necessary, but confirm that all connectors and transmission lines are properly specified for the operating frequency with minimum loss, proper impedance (50 Ohm) and proper VSWR characteristics. Transmission line connector termination is a critical element of the installation. Many ‘factory built’ RF transmission lines do not provide the proper characteristics for proper
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 58 2007-01-03 transmission, despite their published specifications, often due to the fully or semi-automated process of factory termination, which may not have considered the frequency of your system. When buying pre-terminated transmission line, it is strongly advised to obtain the documentation of test measurements on the connected transmission line showing that the loss characteristics and VSWR are within the specified limits specifically at your operating frequency. In addition to factory-built transmission line, self-terminated transmission line can suffer the same issues. Always follow the manufacturer’s termination process EXACTLY, and only use the manufacturer’s authorized tools and connectors for a given transmission line type. The manufacturers of transmission line typically offer instruction and certification for transmission line termination, and may also provide videos illustrating the process. There is no amount of extra care, education, precision, and effort that can be overstated for this process. Once the transmission line is connected to the antenna, traverse the exact route provided by the site planner. There is often a need for a small excess of transmission line near the antenna to accommodate both the need for extra slack as the antenna is loosened and moved for the alignment process, and to accommodate a drip loop for the transmission line and the initial transmission line securing hardware and grounding near the antenna. In addition, the transmission line is typically very stiff, and can provide undue pulling force on the antenna connector. Take care to align the cable with the connector so that it does not provide any torque or strain on the connector. Consult your transmission line manufacturer for the proper transportation, hoisting, securing, and grounding process. Always be very mindful of the entire length of transmission line to ensure that the transmission line is never twisted, kinked, or over-bent beyond the specified bend radius. Once a transmission line is over-bent or kinked, it will likely never recover its specified characteristics, even after straightening, and will often be completely unusable. The opposite end of this primary transmission line typically terminates at the building or enclosure egress point. This is where to locate the RF lightning arrestor. Ensure that a proper termination to the connector-type of the lightning arrestor is made at this location. A drip loop may be required and proper securing hardware and grounding must be accommodated. As soon as practical, weatherproof the connected ends of the transmission line to the antenna and lightning arrestor. This process should be delayed as long as possible to ensure that all systems are working properly before applying the weatherproofing. Once weatherproofing is applied, it may have to be removed for testing or installation modification. With this in mind, if the installation is occurring during inclement weather, take extra care at all times to ensure that no moisture enters any connector at any time. If moisture is suspected to have compromised the antenna or transmission line, it may render those devices useless without any means for remedy except for full replacement. CAUTION
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 59 2007-01-03 Indoor Mounting On rare occasions the antenna can be mounted indoors behind a window. In these cases, there would not be a need for drip loops or an RF lightning arrestor. Use a very short transmission line connected directly between the antenna and the radio mounted nearby. The weatherproofing process can also be omitted. RF Lightning Arrestor RF lightning arrestors provide a direct path to ground for lightning strikes that may couple to or directly hit the outdoor transmission system or antenna structure. The RF lightning arrestor prevents any associated voltage and current from entering the building or enclosure, where it might harm the radio equipment, other equipment, or humans. The following lightning arrestors are examples of proper devices for Exalt Digital Microwave Radios: • Polyphaser AL-LSXM • Andrew BB-BNFNFE-26 Mount and ground the RF lightning arrestor in accordance to the manufacturer’s recommendations. Place it as close as possible to the egress point where the next piece of transmission line enters the building or enclosure. Minimize the distance to the egress to lessen the opportunity for lightning to couple to or strike the unprotected section of transmission line (if any). Where possible, use a bulkhead connector to eliminate any opportunity of this risk. Keep cable lengths behind the arrestor and into the egress substantially short (less than 3'/1m) as a safe practice. Consult a qualified electrician or installer in all cases of grounding and lightning arrestor implementation. Transmission Line from Egress to Radio A single transmission line section from the egress to the radio RF connection is always desired. Minimize the number of connectors and adapters. For indoor runs, a cable ladder or tray may be needed to properly secure the cable. In some cases, a short flexible jumper allows ease of connection to the radio’s RF connector. A properly specified 90º connector can often eliminate this need. An installation with space around the radio to accommodate a gentle bend radius of the transmission line is also good for a direct connection. In all cases, ensure that the transmission line is not a pulling force of the RF connector on the radio. Transmission lines can be very stiff and can damage the connector if not dressed properly. Also, follow the transmission line manufacturer’s instructions for the proper use of cable securing devices.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 60 2007-01-03 Antenna Alignment Antennas must be installed at both ends of the planned link to commence precision alignment. Refer to the Exalt white paper, Antenna Alignment. Antennas are typically aligned using the radio hardware for precise alignment. However, there are many very useful tools available to aid in this process, inclusive of devices specifically designed for the purpose of aligning antennas. Some examples are: • XL Microwave Path Align-R • Teletronics 17-402 Use of these devices may be extremely advantageous as compared to using the radio, because they employ many unique facilities to aid in this process. Using these tools also makes it possible to align the antennas before the radio equipment is delivered. However, many installers successfully use the radios as the means for antenna alignment. There are two primary facilities when using the radio to align the antenna: • RSL voltage test point using a volt meter (recommended) The RSL test point DC voltage is inversely proportional and numerically calibrated to the received signal level. The voltage rises as the antennas are less in alignment, and falls as antennas are more in alignment. The voltage measurement corresponds to the received signal level in measurements of dBm (a negative number for RSL measurements). For example, an RSL of -60dBm yields an RSL voltage measurement of 0.60VDC; an RSL of -45dBm measures 0.45VDC. • ExaltGUI RSL reading indicates the current RSL in dBm. Alignment of the antennas using the RSL test point can be accomplished in the following ways: • Radio near or at antenna location ¶ Temporarily connect the radio to the antenna using a short piece of transmission line, so that the radio is very close to the antenna location – Run wires, as necessary, from the RSL test point to the volt meter so that the antenna installer can directly view the volt meter Using this method, the final RSL voltage readings during alignment may be different (better) than the planned RSL, due to the short RF transmission line. Use the path calculation tool to determine the RSL that should result in this temporary configuration to ensure proper ideal alignment. • Run separate wires from radio mounted location to antenna location ¶ Temporarily connect a set of wires from the RSL test point to the antenna location, to allow the radio installer to use a local volt meter
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 61 2007-01-03 Due to the resistance of the cable, the RSL readings might be impacted. Use the thickest wiring possible. Test the impact of the voltage reading due to the wiring by comparing a direct measurement at the RSL test point as opposed to the end of the wiring. • RF/DC coupler Install a temporary DC coupling device at the radio antenna port and at the antenna connector. Connect the RSL test point to the radio antenna port coupler, and the volt meter to the antenna connector coupler. See DC Coupler for Antenna Alignment on page 117 for more information • Verbal relay/walkie-talkie/mobile radio/cell phone ¶ A person located at the radio front panel can use a short-range communication device or verbal relay to communicate to the antenna installer and read off RSL voltage measurements Only use the browser-based GUI for antenna alignment if there is no other means available. If this method is required, refer to Exalt Graphical User Interface (GUI) on page 64. The RSL reading can be read on a PC or any handheld computing device that supports an HTML browser and Ethernet connectivity. There is a slight delay in RSL readings in the GUI as the RSL levels change. In this case, fine alignment can be done in small adjustments allowing a small gap of time so that the impact of the adjustment on the GUI display catches up to real time.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 62 2007-01-03 Configuration and Management This section describes the command line interface (CLI) and Exalt graphical user interface (GUI). Command Line Interface (CLI) Exalt Digital Microwave Radios provide a CLI to set key parameters on the system. Use the Console port for serial devices, or use the Ethernet MAIN or AUX ports for a Telnet session over a network connection. Connect to the Radio with a Serial Connection For serial interface to the CONSOLE port, on your PC, PDA, dumb terminal, or any other device with a serial interface and text input capabilities, use Hyperterminal or a similar application with the following settings: Bits per second: 9600 Data bits: 8 Parity: None Stop bits: 1 Flow Control: None Use a standard straight-through serial cable to connect between most computer serial ports and the Console port on the radio. A null modem cable is not properly wired for this interface. See Interface Connections on page 119 for wiring details. After establishing the serial connection, press ENTER to display the login prompt. Connect to the Radio through a Telnet Connection Use the following steps for a Telnet connection to the radio through the ETHERNET AUX port using Windows: 1. Open a command prompt, or MS-DOS prompt shell (Start>Run>cmd). 2. Type C:\>Telnet <IP Address> at the command line of the command prompt window. The default IP address is 10.0.0.1 You can reset the default address to a different address through serial CLI using the Console port, or back to the default address by radio reset. Your computer must be on the same IP subnet as the radio to use the Telnet function.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 63 2007-01-03 CLI Screens and Menus Use CLI or Telnet when prompted, and enter the administration level login and password. The default administration login is admin and password is password (or admin for early firmware releases). It is recommended that the default administration password be reset by performing a radio reset (see Reset to Critical Factory Settings on page 52). The serial port CLI and Telnet CLI are identical. Figure 17 shows the three menu choices available after log in. Figure 17 CLI main menu Select 1 or 2 to display the Configuration or Status menus, respectively. Select 3 to exit the CLI/Telnet session. The following selections can be made on all screens: • 0 = back to previous screen • 9 = help • Ctrl+\ (control and backslash keys) = exit session The following depicts the complete CLI tree structure: 1.

Exit Exalt Graphical User Interface (GUI) The Exalt GUI is the primary user interface for configuring and troubleshooting the radio and radio system. A computer or hand-held device with a conventional HTML browser and Ethernet port is required. Microsoft Internet Explorer is the preferred browser. Netscape, Mozilla, and Firefox are also supported. Preparing to Connect If the radios are new, both radios are preconfigured as Radio B, and have the same IP address. The initial priority is to configure one radio to Radio A and assign different IP addresses, unique to each radio. There are two ways to change the IP address: 1. Use the CLI interface through the console port (serial), as described in Command Line Interface (CLI) on page 62 2. Connect to the GUI using the default IP address (10.0.0.1), and change the IP address through the GUI interface. If the radio’s current IP address is unknown, use the CLI interface through the console port to retrieve it and/or change it. Or perform a complete radio reset as described in Reset to Critical Factory Settings on page 52. To connect to the radio’s Ethernet port and use the GUI interface, the accessing computer must match the radio’s IP address subnet. It is therefore necessary to either change the radio’s IP address through the CLI to match the subnet of the computer, or change the computer’s IP address to match the subnet of the radio (such as, a computer IP address of 10.0.0.10 if trying to connect to a radio set to the factory default IP address of 10.0.0.1). There are three ways to configure a radio as Radio A: 1. Use the temporary hardware configuration key, as discussed in Temporary Hardware Configuration Key (Standard Models Only) on page 35. 2. Use the front panel DIP switch, as discussed in DIP Switch Configuration (-16 Models Only) on page 36.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 65 2007-01-03 3. Connect to the GUI and change the configuration, as discussed in this section (preferred). Make Connections It is recommended that one radio at a time be configured, on a bench, before taking the radios to the field for installation: • Terminate the RF connector with a 50-Ohm termination or a fixed attenuator of at least 20dB (see Terminating the RF Connector on page 49). • Apply power to the radio (see Power on page 49). Do not connect the radios in a back-to-back configuration. If the radios are set to their factory default settings, both radios are configured as Radio B and cannot communicate. Both radios also have the same IP address, which causes IP address conflicts. Use the CONSOLE port and CLI interface to configure the IP address to match the accessing computer or connect to the ETHERNET AUX port to the computer’s Ethernet port. The IP address subnet of the accessing computer must match the radio’s IP address subnet to connect using Ethernet (see Preparing to Connect). Either change the computer’s IP address to match the radio, or use the CLI to change radio’s IP address to match the computer. Once connected to the radio using Ethernet, log in to the Exalt GUI. Log In Use the following steps to log in to the Exalt GUI. 1. Open a browser window. Microsoft Internet Explorer is the recommended browser. Netscape, Mozilla, and Firefox are also supported. If there are issues with your browser, please report it to Exalt Customer Care. You may be required to use a different browser to immediately overcome issues. 2. Type the IP address of the radio in the address bar. Figure 18 Initiating the browser connection The following window displays after pressing the Enter key or clicking the Go button in the browser window.

Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 67 2007-01-03 Figure 20 Radio Information page Quick-Start To establish a link on the bench, apply the following basic configurations to the radio terminal. Use the steps in the Quick Start Guide included with the radio. A summary of the items that need to be configured are: • Radio IP address for each end. ¶ Each end must have a different IP address and cannot match the accessing computer’s IP address or any address assigned if radios are part of a larger network. ¶ It may be required to change the IP address of the accessing computer after changing the IP address of the radio so that the IP subnet matches. ¶ The radio IP address is listed on the Administration Settings page.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 68 2007-01-03 • Set one radio as Radio A. ¶ The radio selected as Radio A must be configured. ¶ Radio A/B selection is the Endpoint Identifier parameter on the System Configuration page. ¶ Even though both radios are set as Radio B by default, confirm this configuration on the radio intended to be Radio B. If all other parameters are still configured at their factory default settings, the radios can now be connected back-to-back to verify that the link is communicating and perform any other desired tests. See Back-to-back Bench Testing on page 114 for test information. Navigating the describes each page of the GUI. Most configuration parameter settings are intuitive. The following link parameters must match at both ends for the link to communicate: • Link Security Key (Administration Settings page) • Bandwidth (System Configuration page) • RF Frequency (System Configuration page) • Link Distance (System Configuration page) • TDD Frame Size (System Configuration page) Changing any of these parameters causes a temporary loss of link. The GUI displays a warning and provides an opportunity to cancel changes. Navigating the GUI The GUI provides the primary interface for all configuration and management. There are three sections of the main GUI window, as shown in Figure 21: • Summary status information section (upper-left corner) • Navigation panel • Main window
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 69 2007-01-03 Figure 21 Exalt GUI window description Summary Status Section This section of the Exalt GUI provides a review of the system status. Figure 22 Minimized browser windows for summary status of multiple radios In the screens in Figure 22, the top bar illustrates the alarm condition of the link. The background color of this bar is equivalent to the color of the LINK LED on the radio front panel(s) (see Table 5 on page 47). The information inside the bar is equivalent to the entry of the Link Name, as set by the administrator in the Administration Settings page (see Administration Settings Page on page 72). The background color of the left box illustrates the summary of alarm conditions of the local radio (the radio that matches the IP address). The color follows the same convention as the rear panel SUMMARY LED. The information inside the bar illustrates the IP address and the endpoint identifier (Radio A or Radio B). The background color of the right box illustrates the summary alarm conditions of the remote radio (the radio linked to the local radio). Main Window Navigation Panel Summary Status
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 70 2007-01-03 The ‘local’ radio might be the near-end or the far-end radio, depending on the management interface connection. The terms local and remote refer to the orientation of the radio terminals relative to the IP address you are managing. When making certain changes to a near-end radio without first making changes to the far-end radio, the link may become disconnected unless configuration changes are reverted to their original settings. When making changes that have the opportunity to disrupt the link, always change the far-end radio first, and then the near-end radio to match. The Summary Status Section allows the Exalt GUI to be a rudimentary management system. Minimize the browser window to display just the top bar or the top bar and radio information, and open several browsers on the desktop. When a window status changes to yellow or red, you can quickly maximize that window to determine the issues. Navigation Panel In the navigation panel, pages with sub-pages have a plus (+) to the left of the page link. Click the plus sign or page name title to view sub-page titles. The pages can be collapsed to hide the sub-pages when a minus (–) sign appears to the left of the page link. Management pages are indicated with an X to the left of the page name. Click the X or page name to display the page within the main window.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 71 2007-01-03 Radio Information Page This page provides general information about the local radio terminal. This information is helpful for troubleshooting and for record keeping. Figure 23 Radio Information page
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 72 2007-01-03 Administration Settings Page This page allows contains general parameters for the radio system. The Current Value column lists entries actual settings. Desired changes are entered in the New Value column. After all desired changes are entered, click the Update button to accept and enable changes. Figure 24 Administration Settings Page Most entries on this page are self-explanatory. The following lists unique or important parameters. • Fill in the date and time fields as soon as practical. Events are captured with time/date stamps, which is valuable information for troubleshooting. • Set the Link Security Key to something other than the factory default setting (12 characters, all zeros) at each end. The link security key must match at both sides of the link. If the security key remains at the factory setting, the radio link is open to
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 73 2007-01-03 sabotage by a party with the same radio model. Each link should have a unique security key. If using the same security key for every link in the network, the radio could link to any other radio with the same security key. This is problematic in multi-radio networks. ¶ Note that the security key must be exactly 12 characters. Any printable ASCII character can be used. The link security key is case sensitive. Changing the link security key interrupts transmission until the opposite end is changed to match. Always change the far-end radio first, and then change the near-end radio. • Reset the admin and user passwords. These passwords should not match. If the admin password remains at the factory default setting, it provides an opportunity for random reassignment by a network-connected user. ¶ The new password must be entered twice: once in the main window and again in the confirmation window. If the passwords do not match and the UPDATE button is clicked, the password is not changed and remains set to the previous password. • The License Key is set to all zeros. Enter the license key provided by Exalt to access extended features or diagnostic capabilities. Click Update to accept the changes and enable the new features. License keys are issued by radio serial number, so ensure that the license key used was issued for this particular radio.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 74 2007-01-03 System Configuration Page This page contains several critical system parameters. Figure 25 System Configuration Page Most entries on this page are self-explanatory. The following lists unique or important parameters: • Set the Radio Transmit Power parameter to the designed level. The professional installer sets this value or dictates the value of this setting to the system administrator following the system design and local regulations. In many cases, this value must be set to a proper value to comply with legal restrictions. Improper values can result in liability to the user and/or installer. Changing Radio Transmit Power may temporarily interrupt traffic. Small changes in output power do not normally interrupt traffic, but larger changes may.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 75 2007-01-03 ¶ Do not adjust the Radio Transmit Power parameter to a value higher than is legally allowed. ¶ Do not adjust the Radio Transmit Power parameter lower than the link budget and fade margin can afford. The link may be lost and unrecoverable through GUI control. If the link is lost due to reduction of Radio Transmit Power, travel to the radio location(s) may be required to reset the value. • Set the Bandwidth parameter to the designed level. The value of this is determined in the design/engineering stage. The Bandwidth parameter must also match at both ends of the link. In conjunction with the Mode parameter, the Bandwidth parameter directly relates to the capacity, latency, and the number of TDM circuits supported. The transmitter and receiver bandwidth are modified using this parameter, making it critical that it be set with respect to the local RF noise and interference profile, and/or in relation to any multi-link network design. Changing Bandwidth will temporarily interrupt traffic. The Bandwidth parameter must match at each end. Adjust the far-end radio first, and then the near-end radio. Changing Bandwidth changes the radio’s threshold. A narrower bandwidth has better threshold performance and improved interference immunity, therefore if changing to a wider bandwidth, there is an opportunity that the link may be lost and unrecoverable through GUI control. Check the available fade margin and interference profile to determine if the impact to threshold and increased bandwidth is acceptable to maintain the link and the desired performance. If the link is lost due to increasing the Bandwidth parameter, travel to the radio location(s) may be required to reset the value. • Set the Mode parameter to the designed selection. The value of this setting is determined in the design/engineering stage. The Mode parameter must match at both ends of the link. In conjunction with the Bandwidth parameter, the Mode parameter setting directly relates to the capacity of the system, as well as critical RF parameters, including receiver threshold, carrier-to-interference ratio, and in some cases, maximum radio transmit power.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 76 2007-01-03 Changing Mode will temporarily interrupt traffic. The Mode setting must match at each end. Adjust the far-end radio first, and then the near-end radio. Changing Mode changes the radio’s threshold, carrier-to-interference ratio, and also may have impact on the Radio Transmit Power. A lower mode has better threshold performance and carrier-to-interference ratio, and in some cases, higher output power, therefore if changing to a higher mode (for example, from Mode 1 to Mode 2), there is an opportunity that the link may be lost and unrecoverable through GUI control. Check the available fade margin and interference profile, and determine if the impact to RF performance is sufficient to maintain the link and desired performance. If the link is lost due to increasing the Mode parameter, travel to the radio location(s) may be required to reset the value. • Set the RF Frequency parameter to the designed point. The value of this setting is determined in the design/engineering stage. RF Frequency must match at both ends of the link. It may be critical to set RF Frequency with respect to the local RF noise and interference profiles, and/or in relation to any multi-link network design. The frequency selection section includes the ability to select from either the complete list of frequencies (“All”) that can be tuned for the selected band and bandwidth, or a pre-selected list of non-overlapping center frequencies (“Preferred”) that Exalt determined provides the most flexible collocation opportunities for large networks of Exalt radios For the EX-5i families, the frequency selection section includes a band selection button that must be enabled for the frequency band of operation for which the link was engineered. In some cases, some bands may not be selectable due to regulatory constraints. Changing RF Frequency will temporarily interrupt traffic. The RF Frequency parameter setting must match at each end. Adjust the far-end radio first, and then the near-end radio. If the RF Frequency parameter is changed to a frequency with interference, the link may be lost and unrecoverable through GUI control. If the link is lost due to changing the RF Frequency parameter, travel to the radio location(s) may be required to reset the value. • Set the Endpoint Identifier so that one end of the link is set to Radio A and the opposite end set to Radio B. In single-link networks, it is unimportant which end is designated A or B. In multi-link networks, however, it may be important to orient the links so that at any collocation site (where there are multiple radios of the same type at the same site), all radios are set to the same Endpoint Identifier (A or B). See Link Orientation and Synchronization on page 34. Changing Endpoint Identifier parameter requires a reboot of the radio to take effect. The reboot temporarily interrupts traffic.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 77 2007-01-03 • Set the Link Distance parameter to the range that is equal to or greater than the actual link distance. The value of this setting is determined in the design/engineering stage. Changing Link Distance parameter will temporarily interrupt traffic. The Link Distance setting must match at each end and must not be less than the actual link distance. Adjust the far-end radio first, and then the near-end radio. If the Link Distance parameter is changed to a setting less than the actual distance, the link may be lost and unrecoverable through GUI control. If the link is lost due to this situation, travel to the radio location(s) may be required to reset the value. If the Link Distance parameter setting is set to a distance unnecessarily higher than the actual link distance, the radio may have substantially reduced performance with respect to throughput and latency. • Set the TDD Frame Size parameter to the designed level. The value of this setting is determined in the design/engineering stage. The TDD Frame Size parameter must match at both ends of the link. The TDD Frame Size parameter setting directly relates to the capacity, latency, and number of TDM circuits that can be supported over the given link distance. In multi-link networks, especially where there are collocated links, it is also important to set all radios to the same TDD Frame Size setting to avoid self-interference. Note that the GPS or internal synch function may be necessary for these networks. See Time Division Duplex (TDD) Factors, Link Orientation and Synchronization, and Radio Synchronization for more information. Changing the TDD Frame Size parameter will temporarily interrupt traffic. TDD Frame Size parameters must match at each end. Adjust the far-end radio first, and then the near-end radio. If the TDD Frame Size parameter is set to a value that cannot be supported for the link distance, the link may be lost and unrecoverable through GUI control. If the link is lost due to this situation, travel to the radio location(s) may be required to reset the value. • The External Alarm Inputs parameter can be ignored unless connecting external alarm sources to the radio for monitoring the status of these external alarms through the radio management system (see Interface Connections on page 119).
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 78 2007-01-03 Ethernet Interface Configuration Page This page allows the administrator to set the muting, alarm, and duplex settings of both the ETHERNET MAIN and AUX connections. It also allows determination of the management information for in-band (carried over the air and available from both the MAIN and AUX connectors on either end of the link) or out-of-band (not carried over the air and only available from the local AUX connector). Figure 26 Ethernet Interface Configuration Page Muting the MAIN connection is desirable when connected equipment senses Ethernet signaling and makes decisions (such, as spanning tree protocol enable) based on the presence or lack of presence of the Ethernet signal. If the MAIN connection has muting enabled, the port mutes when the link is not active. It may be desirable to disable the alarming of the AUX connector if it is not used. Set the Ethernet interfaces on the radio and connected equipment to 100/full-duplex for best performance. If the Ethernet ports are set to auto-negotiation, poor throughput performance may be a result, as well as intermittent disconnections of the Ethernet connection.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 79 2007-01-03 T1/E1 Configuration Pages These pages allow the administrator to selectively enable or disable the T1 or E1 circuits, one at a time. For enabled T1/E1 circuits, additional configuration, including loopback functions, are available. Disable the unused T1 or E1 so that the alarms are turned off and more throughput is allocated to the Ethernet interface. Every enabled T1 or E1 input, even if there is no T1 or E1 signal present, reduces the aggregate throughput of the Ethernet interface by roughly 3Mbps (for T1) or 4Mbps (for E1). This page toggles between T1 and E1, as required, by clicking the Set to T1 or Set to E1 button. A warning displays that a reboot is necessary, and the radio reboots if the administrator continues. This will interrupt traffic. It may be necessary to re-login to the radio after the reboot completes. T1/E1 mode self-coordinates across the link if the link is active. This means that it only needs to be set while connected at one end. In addition, enabling and disabling T1/E1 circuits also self-coordinates across the link if the link is active. If a link is not active and T1/E1 enabling is a mismatch when a link is first created, the Radio A configuration for T1/E1 enabling supersedes the settings on the Radio B configuration, and changes the settings on Radio B. Certain combinations of the TDD Frame Size, Link Distance, Mode, and Bandwidth parameter settings limit the number of T1/E1 circuits that can be carried by the radio. In these cases, certain fields on the T1/E1 Interface Configuration pages are not available, starting with the highest port number. For example, for a 4x T1/E1 radio version, if only three (3) circuits can be carried, port 4 is not available for configuration and is disabled. If only two circuits can be carried, both ports 3 and 4 are not available. Increasing the TDD frame size and Mode parameters, and/or increasing the Bandwidth parameter results in an increase in the supported number of T1/E1 circuits. For ‘-16’models, the highest number channels that are configurable (based on the currently installed license key) are disabled if they cannot be supported with the current settings. T1 Interface Configuration Page This page allows the administrator to enable/disable each individual T1 channel, set the Line Build Out (LBO), Line Code (either AMI or B8ZS), and AIS enabling/disabling for each input. If enabled, the radio places an AIS code on the output of the associated interface if and when the link fails or when there is no T1 signal available from the far end to provide the user at the local end. Loopback controls are also provided (see T1/E1 Loopback on page 81).
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 80 2007-01-03 Figure 27 T1 Interface Configuration page (standard models) E1 Interface Configuration Page This page allows the administrator to enable/disable each individual E1 channel. The AIS can also be enabled and disabled for each input. If enabled, the radio places an AIS code on the output of the associated interface if and when the link fails or when there is no E1 signal available from the far end to provide the user at the local end. Loopback controls are also provided (see T1/E1 Loopback on page 81).
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 81 2007-01-03 Figure 28 E1 Interface Configuration page (standard models) T1/E1 Loopback Loopback is provided for any enabled T1 or E1 port. As shown in Figure 29 and Figure 30, the choices are: • No Loopback (default) • External (local) • External (remote) • Internal Only one Internal loopback can be enabled at any time. All loopback configurations control the loop at the Line Interface integrated circuit, which is the device wired directly to the front panel ports. External loopback modes are used in conjunction with an external test source. The designation of ‘local’ or ‘remote’ refers to where the loopback is occurring relative to the location where the loopback is implemented. That is, on the radio being accessed, if External (remote) is selected, this loops the signal back at the remote radio interface back towards the local radio. Likewise, if External (local) is selected, the signal loops back at the local interface towards the remote radio (Figure 29 and Figure 30).
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 82 2007-01-03 Figure 29 External (remote) loopback Figure 30 External (local) loopback When a local T1/E1 port is configured for External (remote) loopback, it is the same as configuring the remote radio for External (local) loopback. Internal loopback uses an internal test source, and sends the test source signal across the link, looped at the remote radio’s interface, returned to the local radio, and looped at the local radio’s interface back to the source. The inputs at both ends are looped back at the line level. Figure 31 illustrates the internal loopback function.

Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 83 2007-01-03 File Transfer Page This page allows the administrator to upload and download files to and from the radio. Two types of files can be uploaded: configuration and radio firmware. When uploading Configuration Files, current configuration parameters are immediately overwritten, and the unit automatically reboots. When uploading radio firmware files, the file is placed into reserve memory space. After the new radio firmware file uploads, use the File Activation page to enable the files (see File Activation Page on page 86). Up to three types of files can be downloaded: configuration, radio firmware, and MIB. The MIB file refers to the Management Information Base related to the Simple Network Management Protocol (SNMP) function, and is only available on models which support SNMP. See Simple Network Management Protocol (SNMP) on page 87 for more information. Check the File Activation page before uploading radio firmware files. New file uploads overwrite the secondary file location. If important files reside in the primary or secondary file location, download them before uploading the new files. Only the active radio firmware file can be downloaded. Therefore, to download the reserve file, it must first be activated (using the Swap button). See File Activation Page on page 86. Figure 32 File Transfer Page
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 84 2007-01-03 Use the following steps to download a file 1. Select the type of file to download (configuration or radio firmware) 2. Click the DOWNLOAD button and wait for the radio to prepare the file for download. For the MIB file download, a second page/link appears (Figure 33). 3. Right-click the link on the page to download the file to a desired location. Figure 33 File Transfer page—download file link File download and upload is useful when configuring several radios with similar settings. A copy of the configuration file can also help restore radio settings. In addition, a copy of the Exalt default configuration file is helpful to restore the radio to factory settings. Do not change the name of any downloaded file. The configuration file must be named config.nv. To keep track of multiple configuration files, use a folder naming system or temporarily rename the file, however, it must be named config.nv it can be uploaded to a radio. Never change radio firmware file names under any circumstances. If copying the same configuration file into multiple radios, take as some parameters will match and that may be undesirable. However, it may be easier to change just a subset of parameters rather than every parameter.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 85 2007-01-03 The following parameters can cause problems or confusion if they match at each of a link: • Radio Name • Endpoint Identifier • IP Address • IP Subnet Mask • Default Gateway The following parameters can match at both ends of the link: • Link Name • Link Security Key (although each link should be different) • Admin and User passwords • Bandwidth • RF Frequency • Link Distance • TDD Frame Size • T1/E1 configurations • Ethernet configurations
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 86 2007-01-03 File Activation Page Use this page to move stored or uploaded files for use on the radio. The page indicates which file is currently in use, and which file is available for use. Click the Swap button to place the file in the Alternative File column into the active state and move the file in the Current File column to the Alternative File column. Figure 34 File Activation page In all cases, the radio reboots after a new file is selected using the Swap function. This places the radio out of service for a short period.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 87 2007-01-03 Simple Network Management Protocol (SNMP) Configuration Use SNMP to manage networked devices and execute the following functions: • GET: Obtain information from the device, such as a configuration setting or parameter. • SET: Change a configuration setting on the device. • TRAP: The device proactively informs the management station of a change of state, usually used for critical alarms or warnings. Currently the SNMP implementation does not support TRAP functions. For critical alarms, use the GET command for specific alarm conditions. One feature of the SNMP implementation is that system configuration changes do not take effect using the SET command. Instead, groups of configuration settings can be preconfigured for global change, and a single ‘Save’ (Commit) command implements all changes. When some parameters are changed, a link may drop and/or management control lost. MIB files allow many parameters to be set at once, allowing only a temporarily dropped link or management control issue. The opposite end radio can be quickly reconfigured, with little downtime for the link and management control. The save (Commit) command is similar to the Update button. Dropped links or management control issues do not occur with every parameter change. Many configuration changes do not impact traffic or management access. Exalt radios utilize SNMPv3, a high security version of SNMP, to ensure secure access to and storing of management data. The SNMPv3 security string matches the admin and user passwords. Passwords must be eight characters or longer. Currently not all EX-series radios implement SNMP. Check the software release notes to verify that the function is available. Generally, the radio supports SNMP when MIB files are listed on the File Activation Page. The SNMP MIBs are organized similar to the GUI. Become familiar with the GUI before using the SNMP function.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 88 2007-01-03 Alarms Page This page provides an easy-to-read summary of the alarm status of both local and remote radios. The colors on this page reflect the color of the alarms displayed on the radio front panel. However, additional detail displays on this page to aid in quick assessment of issues and status. Figure 35 Alarms page (standard models) See Table 5 for more information on the front panel LEDs. This page displays additional information about the alarm status. • The Internal Fan alarm monitors all three internal fans. The radio only requires that one fan be operational for full-specification performance. The additional fans are provided for redundancy and to increase overall reliability. If one or two fan alarms are yellow or red, it is prudent to plan to install a spare radio at the earliest opportunity and return the radio for repair (RMA authorization required). If all three fans are in alarm, the radio must be taken out of service immediately, as damage may occur to the internal electronics, especially in hotter environments or where thermal exchange from neighboring equipment exists.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 89 2007-01-03 • The Temperature alarm monitors the internal temperature of the unit based on specific points inside the radio chassis. It is normal for the internal temperature to be above the ambient temperature, so the temperature reading may be higher than the highest specified ambient temperature. When the internal electronics reach a point that is higher than the normal temperature rise at the highest ambient temperature, the temperature alarm turns yellow. Power down the radio as soon as possible, and investigate the cause of the temperature rise before the radio is put back into service. In almost all cases, a temperature alarm is due to an external cause, unless the fans in the unit are also in alarm, in which case, the fans are the likely cause.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 90 2007-01-03 Performance Page This page provides statistical information about the performance of the system in relation to the integrity of the user data and the RF link. Figure 36 Performance page • The Current BER field indicates the current bit error rate of the link. If the link is operating perfectly, this should indicate zero. Generally, the link should remain at a BER less than 1x10-6 (1 bit out of every million bits errored). This is the threshold performance specification and the standard to which the link was engineered. However, radio links can and are affected by weather, interference, and other external sources and will occasionally have a higher error rate. A link remains operational unless the BER exceeds 1x10-3 (1 bit out of every hundred bits errored). Consult the link design engineer for an understanding of the predicted error rate of the radio link as it has been designed. Many applications are unaffected by bit errors, but TDM circuits (for example, T1 or E1) are more sensitive. Also, if the link operator is providing a service guarantee, this value may need to be monitored or examined in cases of service issues. The behavior of BER in relation to other alarms or measurements and external events can be very helpful in troubleshooting activities.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 91 2007-01-03 • Current RSL is the measurement of the received signal level at the radio antenna port. This is the measured level of the RF signal coming from the opposite end of the radio link. The link was engineered to a specific RSL by the link design engineer, and this RSL should be obtained during installation and remain relatively stable during the operation of the link. RSL can and will vary as a result of weather changes and other external sources, such as path obstructions. Once again, this variation was part of the original design to achieve a certain level of performance over time. Bit errors occur when the RSL falls to a level within roughly 3dB of the threshold specification. When the RSL falls below the threshold specification, the link disconnects and will not reconnect until the RSL is above the threshold specification. The behavior of RSL in relation to other alarms or measurements and external events can be very helpful in troubleshooting activities. • Errored Seconds (ES) indicates the total number of seconds that occurred where there was at least one bit error since the last time that the radio statistics counter was reset. Generally, ES are not a significant concern, so long as they are not continuous or above the anticipated performance based on the original link engineering goals. If ES are continuous or at a high rate, this is normally an indication of poor link performance due to poor RSL or interference, or severe impact by weather or other environmental factors. However, similar to the performance factors previously listed, ES can and will occur in any radio link. Once again, consult the link engineer to determine the original design goals, and compare actual performance to these expectations to determine if any improvements are necessary or if other problems may be causing excessive ES. Unavailable Seconds do not register as ES. In other words, the ES counter counts all seconds that are errored NOT INCLUDING the seconds that were classified as unavailable. The total number of seconds with errors or outages is the sum of ES and Unavailable Seconds. • Unavailable Seconds (also called UAS) are similar to ES, but this counter keeps track of every second where the bit error rate equals or exceeds 1x10-3, as well as any seconds where there is a complete loss of radio communication, over the period since the last counter reset. If Unavailable Seconds are continuous or at a high rate, this is normally an indication of poor link performance due to poor RSL or interference, or severe impact by weather or other environmental factors. However, similar to the performance factors listed above, Unavailable Seconds can and do occur in any radio link. Consult the link engineer to determine the original design goals, and compare actual performance to these expectations to determine if any improvements are necessary or if other problems may be causing excessive Unavailable Seconds. • Minimum RSL indicates the worst (lowest) received signal level that occurred since the last counter reset. It is helpful to know if the RSL dropped significantly from the normal level, or has reached a level near or below threshold. • Minimum RSL Timestamp indicates the date and time when the Minimum RSL occurred. This is helpful for general troubleshooting, and especially comparing to items in the event log or diagnostic charts from the same time period.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 92 2007-01-03 • Maximum RSL indicates the best (highest) RSL that occurred since the last counter reset. This indicates the best performance of the radio link, which is normally equal to the installed value, and is usually the designed value. • Time Since Reset indicates the amount of time passed since the last counter reset. This helps to quantify the seriousness of other statistics, such as ES and Unavailable Seconds, if there have been high numbers of ES and/or Unavailable Seconds over a relatively short period of time. Each end of the link statistics on this page can be independently reset using the Reset Statistics button for the local or remote radio. It is good practice to reset the statistics at the time that the link is commissioned (after all antenna alignment is complete and stable RSL at designed levels is achieved, and no more system reboots are anticipated). Make a habit of viewing this page regularly, make records of the performance, and reset the statistics so that the counters can more precisely pinpoint issues. Resetting statistics from one end also resets the statistics for the same radio at the opposite end. That is, if the Local statistics are reset, logging into the remote end shows the Remote statistics on that end (which is the local radio in the first condition) as being reset at the same time.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 93 2007-01-03 Event Log Page Use this page to review a list of the events logged by the radio. The following items are listed in the event log: • Alarms • Alarms clearing (Normal) • Radio Reboots Figure 37 Event Log page
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 94 2007-01-03 Every event is tagged with the time that the event occurred, and a severity and type. The event log also allows filtering to limit the view of the log to the lowest level of desired information. For example, a filter level of Minor displays Minor, Major, and Critical severity events. The log contains the last 200 events. Events are deleted on a FIFO basis, erasing the oldest entries to make room for the newest entries. The event log can be cleared and be downloaded from the radio (some models may require a software upgrade to enable this feature). A screen capture of the browser window can serve as a useful record.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 95 2007-01-03 Diagnostic Charts Page Use this page as an aid in troubleshooting. This page illustrates the historical (and current) performance for three parameters: RSL, Radio Temperature, and BER. The horizontal scale illustrates 120 points of time measurement and is synchronized on all three graphs. The scale displays in minutes, hours, or days from the last two hours (120 minutes), five days (120 hours), or four months (120 days). All information is stored, so all of these periods are available for short- and long-term performance analysis. The right side of a graph represents the most recent measurement, and data ‘marches’ from the right-to-left at every interval. The vertical scale of each chart independently scales to show the maximum resolution based on the maximum variation of the data over the selected time measurement.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 96 2007-01-03 Figure 38 Diagnostic Charts page Use the cursor to point to any spot on any of the three charts, and all three charts illustrate the measurements taken for that time interval in the upper-left corner of each chart. The time interval is indicated by T=(value). This is followed by the value of the measurement, listing the highest value, lowest value and average value measured over that time interval. For example, in Figure 38 the displayed time interval is hours, and the cursor is held at the T=13 mark on the horizontal axis. The measurements shown indicate performance from 13 hours ago. The high/low/average values shown on each chart are measurements made across that specific one-hour interval.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 97 2007-01-03 Changes in RSL often have an impact on BER, and this can be confirmed by looking for synchronized events. When BER events occur without corresponding changes in RSL, this normally indicates interference, atmospheric changes, transmission system issues (such as problems with cables, connectors or antennas), or possibly radio hardware problems. It is also useful to help determine if changes in radio temperature are occurring, and if they are having any impact on RSL or BER. If the radio is mounted in an environmentally controlled location, this has less relevance. However, temperature monitoring can be helpful to ensure that the radio is operating within specifications.

Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 100 2007-01-03 Troubleshooting This section provides information regarding troubleshooting of common issues and alarms on these radios. Exalt Digital Microwave Radio systems are designed by Exalt’s expert engineers with extensive experience through multiple generations of microwave radio design. These new-generation systems contain extensive diagnostic tools, alarm indications, and troubleshooting aids. And, as compared to other systems in their class, are easier to install, maintain, and troubleshoot. The GUI provides information to aid in troubleshooting (see Diagnostic Charts Page on page 95). Contact Exalt Customer Care for further assistance with issues with your Exalt radio and with suggestions on how the radio and documentation can be improved. General Practices Troubleshooting a microwave radio link can be a complex task. Approach troubleshooting as a process of elimination, and first determine which portions of the system are operating properly. In a vast majority of cases, failures or poor performance of microwave links is attributed to something other than the microwave radio hardware. In this respect, the back-to-back bench test (see Back-to-back Bench Testing on page 114) is very important to determine if radio hardware is operating properly and eliminate many variables in the troubleshooting process. If a back-to-back bench test fails, then the radio hardware is either broken or the radios are improperly configured. Upgrade the radio to the most current release of firmware, and/or reset the radio to its critical factory settings, following the quick start guide instructions and those in Configuration and Management, helps to confirm if configuration issues cause failure. The most common issues with microwave radio links are: • An improperly terminated RF cable • Multipath propagation • RF interference • Path obstruction • Misaligned antenna • Faulty antenna • Improper grounding • Insufficient link margin in the design/implementation • Moisture in the transmission system (antenna feed and/or RF cable)
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 101 2007-01-03 If the radio link has been operating without issues and is exhibiting new poor performance behavior or becomes completely inoperative, the troubleshooting process should pay close attention to any conditions that may have changed between the time when the system was working without issue and the time when the issues started. Also, it can be helpful to compare some performance parameters of the system before and after the presence of issues. Often the source of the issues can be determined by thoughtful consideration of changes, such as: • Changes in weather, including high winds • Changes made to the radio equipment, transmission system, or connected equipment • New radio systems or electronic equipment the nearby radio or transmission system • New construction nearby either end of the link, or along the path • Tree growth, flooded fields, or changes in rivers/lakes along the path Verify that configurations are set as follows: • RF matches at each end of the link • Bandwidth matches at each end of the link • Link distance matches at each end of the link • TDD Frame Length matches at each end of the link • Endpoint Identifier is different at each end of the link (one end Radio A, one end Radio B) • Ethernet interfaces are enabled, as desired • AUX Ethernet is set for in-band or out-of-band NMS, as desired • T1/E1 enabling matches at each end of the link • Link security key matches at each end of the link Also, use the ExaltCalc tool in the design phase to determine the optimum setting for the Bandwidth and TDD Frame Length parameters for the given link distance, and provides guidance to the expected RF link performance, as well as throughput, latency, and number of supported T1/E1 circuits. Typical Indications of Issues In many cases, microwave radio users do not notice changes or degradation to the radio system until the radio system fails completely or becomes highly errored or significantly intermittent. However, regular management of the radio system can help indicate changes in performance that have not yet impacted user performance, but may impact performance at a later date if left unchecked or unaddressed. The administrator can use this as an opportunity to be proactive and monitor the radio link performance regularly, watching for unexplained or unexpected changes in performance and trends in performance changes.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 102 2007-01-03 Most importantly, monitoring radio system RSL over time indicates the performance of the radio system. Address any long-term drop in RSL and erratic or unsteady RSL. Some RSL changes are expected and weather patterns and the related multipath can cause dramatic RSL changes resulting in system outage. However, that outage should not occur at a significantly greater rate than the designed long-term performance. Consult the path design engineer for more information about link reliability expectations and anticipated RSL deviation. In addition, regular inspection of the transmission system (RF cables and antennas) and paying close attention to changes along the path, such as construction or tree height, or new microwave radio installations nearby, can be extremely helpful and proactive. When link performance is very poor, alarms on the radio front panel and within the radio’s management system indicates particular failures. Consult this manual for more information on the specific alarms and diagnostics, or contact Exalt Customer Care for assistance. Exalt Customer Care is primarily motivated to determine if the radio hardware is faulty and require return for repair, and to help execute an effective and efficient repair and return process for radio terminals believed to be faulty. However, Exalt Customer Care provides advice regarding the total radio system and RF path engineering and environment, and advises on troubleshooting. End users should first contact the installer and/or designer of the system. In many cases, an in-depth understanding of RF design is required, and on-site analysis and special test equipment, may be necessary. Compared to phone support from Exalt Customer Care, troubleshooting is much more expeditious if the professional installer and/or link designer examines the system and reviews the management information in the GUI. In turn, if the professional installer and/or link designer contacts Exalt Customer Care, the process to rectify the system is much more expedient due to the in-depth knowledge related to the implementation and the RF environment. Improper RF Cable Termination Improper RF cable termination is a very common problem. In many cases, this is a problem that occurs during installation and is not a problem that suddenly appears. However, if cables are moved or flexed, especially near the termination points, and radio errors, changes in RSL, or other performance issues occur, this is a certain sign of this issue. Another relatively easy method to test for this condition is to decrease the output power of the radio system (at each end, one end at a time). A poor RF cable termination may be reflecting too much RF energy back into the radio system, and reducing output power reduces the reflected energy at a faster rate than the transmitted energy towards the far end. Be careful not to reduce the output power to the point where the radio’s threshold is reached. Typically, a reduction of just 3 to 6dB is enough to determine if this is the issue. If the reduction of output power clears the error condition, this is the likely cause.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 103 2007-01-03 Use a reflectometer or meter that can read VSWR at the operating frequency to identify poor terminations as well as poor antenna feeds. The Praxsym VSWR meter is an excellent tool for this purpose Multipath Propagation Multipath propagation is a term that encompasses changes to the RF path, such as reflections and/or refraction, causing partial or complete destruction of the radio signal, and thus excessive bit errors and/or system outages. Rapid changes in temperature, inversion layers, humidity, air pressure, water evaporation, as well as standing water or moisture on objects along the path are all examples of changes that can cause multipath propagation. New building construction near either end of the path or along the path can cause new reflection characteristics. If your system has been operating without issue and is suddenly experiencing issues that are symptomatic of a certain time of day or related to change in climatic events or some of the external factors listed above, this is likely the cause. Consult a professional RF path engineer in these cases. Often, minor repositioning of the antennas at either or both ends can reduce or eliminate these problems. RF Interference RF interference is usually indicative of another radio system nearby either end of your radio system or aimed towards one or both ends of your radio system – usually at or near the same frequency and usually a signal level similar to the level of the signal of your radio system. Other forms of RF interference also exist, such as electronic equipment placed close to the radio chassis or transmitters that couple onto the cabling or grounding system of the radio. Microwave ovens and wireless communication devices used near the equipment or cabling are examples of electronic equipment interference. The EX-2.4i and EX-5i operate in license-exempt bands. Microwave ovens, wireless Internet devices and cordless phone technology may also use this frequency band. It may be necessary to separate the radio chassis, cabling system and antenna from these devices. RF interference, like most other causes of problems, is indicated by significant bit errors and/or system outages. One means to determine presence of interference is the use of a spectrum analyzer that covers the same range as the radio system. A professional RF engineer can use a spectrum analyzer to locate sources of interference, measure these sources, and determine potential remedies to take to operate in the presence of interference. If a spectrum analyzer is not available, the radio’s RSL port can help determine RSL levels of interfering signals. By turning the far-end radio off, the residual RSL measured
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 104 2007-01-03 by the radio indicates the level of interference seen by the radio. It is possible that interference levels below that which can be measured still have an impact on the radio system – especially if the radio system has low fade margin or is using a high order modulation. The EX-2.4i and EX-5i families provide considerable flexibility to tune to different frequencies across the bands within which they operate. This is the easiest method to use to try to avoid existing interference. In addition, the occupied bandwidth of the radio can be reduced. This, along with re-tuning, can be very effective, however throughput is reduced. Repositioning the antenna and/or changing polarization, or upgrading the antenna to a higher gain, and/or using a high-performance antenna, are all secondary means that can be used. It may be necessary to perform combinations of both radio changes (retuning, occupied bandwidth reduction) and antenna system changes (position, polarization, upgrade). The EX-4.9i radio operates under licensed regulations. If interference is suspected, the local frequency coordination organization, or other users of the spectrum should be consulted before re-tuning the radio to a different frequency channel. Path Obstruction A path obstruction is defined as an object, such as a building or tree, impeding the proper path of the radio system. If the system design was proper at the time of installation and issues arise at a later date, an updated path profile and survey may be necessary to identify changes in path clearance. Misaligned Antenna At the time of initial installation, it is critical that the antennas at each end are properly aligned and that the designed RSL is achieved. However, antennas may become misaligned due to high winds, changes in the guy-wiring systems keeping the antenna mast stable, or loosening of the antenna mounting hardware. A reduction in the RSL of the link is symptomatic of this condition, but this condition is not the only condition that results in a reduction of RSL. However, if conditions occur where the antenna alignment may be suspected, the mechanics must be inspected and the antennas realigned. Faulty Antenna A faulty antenna is rare, but is still a possibility. In some cases, the mechanics of the antenna feed can get moisture inside, or a bad or weak connection in the pin and connector structure of the antenna may occur. A VSWR measurement of the antenna connection can be made to verify this condition.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 105 2007-01-03 Improper Grounding In addition to being a potential human safety issue, improper system grounding is a somewhat common condition that can cause continuous bit errors or bit errors when metal objects come in contact with the radio, transmission system, or racking system. If touching the radio causes errors, grounding is the cause. It can be difficult to identify grounding problems, but a professional electrician can normally inspect a system and identify if there are deficiencies in the grounding system. Insufficient Link Margin Ideally, the link was designed with enough link margin (fade margin) to allow for multipath propagation and atmospheric fading and still remain reliable. In some cases, link margin is compromised by economic factors, such as using low-cost RF cabling or lower-cost antennas that have less gain or deficient performance compared to higher cost transmission system components. In some cases, there may be antenna size restrictions that forced the design to not have the desired amount of link margin. If the link was designed with poor link margin, there are likely many cases of bit errors and outages. The antenna system and transmission line can be upgraded to help reduce this. If the link design was installed with sufficient margin, but RSL is reduced, the remaining link margin may no longer be enough to maintain a reliable link. The causes of RSL reduction were previously described, but are usually due to new path obstruction(s) or antenna misalignment due to wind or mechanical factors. The antenna height or location can be changed to overcome new obstructions. Realignment of the antenna, and/or improvement to mechanical structures can help overcome antenna misalignment. Moisture in the Transmission System If the connectors on cables and antennas and egress junctions are not properly weatherproofed, moisture can get into the transmission system and cause significant error conditions and erratic performance. In many cases, the transmission system must be replaced. A VSWR meter is one means to identify such issues. Physical inspection can be helpful, and if changes to the weatherproofing occur (such as cracks), the weatherproofing must be replaced before it leaks.

Exalt i-Series Installation and Management Guide 5000001 114 2007-01-03 Back-to-back Bench Testing Use back-to-back bench testing to test the radio before installation, pre-configure the radio and connected equipment before installation, or in the troubleshooting process to identify if the radio hardware is the source of a system issue. It is a critical process, and often required or highly desirable for any installation or troubleshooting exercise. This section describes how to properly configure the radio hardware and accessories for a proper back-to-back bench test. For radio testing, there are two types of back-to-back configurations: 1. Basic test (test general operation) 2. Specification performance verification Basic Test The basic test is a simple test of radio functionality. It verifies that the radios are properly configured to communicate to one another, and verifies general radio performance as operational. For the basic test, the following items are needed: • Radio pair • Powering source • RF interconnect cable(s) (any length – short is best) • Fixed or variable attenuation, between 60 and 90dB (note: attenuation for basic test does not to be calibrated or precise) • Computer/terminal with either serial or Ethernet port (helpful, but not necessary) ¶ If no computer is available, use the temporary hardware configuration key or DIP switch, depending on radio model (see Radio A/B Configuration on page 34) Connect the items as follows: 1. Connect attenuation and (known-good) RF cable(s) between radio pair, shown in Figure 41. 2. Configure one radio as Radio A; the other as Radio B 3. Power on radio pair
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 115 2007-01-03 Figure 41 Basic back-to-back bench test configuration After connecting and powering on, observe the front panel LEDs to verify that the LINK and STATUS LEDs are green. If so, the radios are communicating and all radio-related alarm conditions are normal. It can be beneficial to have a computer to verify configuration in case of red LEDs or to pre-configure the radio as desired for operation. Follow the instructions in Configuration and Management. Specification Performance Verification The specification performance verification is a more detailed test that allows you to verify that the radio’s output power and threshold specifications are being met. This is typically a test that would only be performed in a troubleshooting scenario, but can be performed before installation to provide a detailed record or ensure radio performance before installation. This test is identical to the basic test, but in place of the fixed attenuation, it requires the use of calibrated variable attenuation, or a set of calibrated fixed attenuators, or a combination of both, adding to a total attenuation value of 120dB, as measured at the operating frequency of the radio. In addition, a volt meter or computer is also required. Connect the system as shown in Figure 41, using the combination of fixed and variable attenuation between the radio’s RF ports. Connect the volt meter to either radio’s RSL test point and associated reference ground connection. In this test, it is desirable to use pre-tested RF cables, known to be good, and the insertion loss is known at the operating frequency. If the cables are short (6'/2m or less), you can estimate the loss, including connectors, to be less than 1dB each. The estimate of cable loss is critical to the overall confidence of the measurements made in this test. There are two critical specifications that can be tested in this configuration: 1. RF output power 2. Radio receiver threshold To measure transmitter output power, simply insert any value of attenuation between the radios between 60 and 90dB. Ensure that both RF output power settings are at maximum. RADIO B RADIO A ATTENUATION (60-90DB) RF PORTS POWER (CONNECT LAST) POWER (CONNECT LAST) COMPUTER CONSOLE PORT SERIAL PORT
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 116 2007-01-03 Use the volt meter to measure RSL in both directions. The RSL measured value should match the appropriate value according to the inserted attenuation, such as: RSL = RF Output Power – cabling losses – total attenuation Verify output power by adjusting output power using the Exalt GUI (in administration mode) and evaluate the corresponding change to the RSL measurement. For threshold testing, the key is to insert a measured amount of loss that is close to, but not exceeding the radio’s specified system gain. System gain is the difference between RF output power and receiver threshold. At your selected modulation and bandwidth settings, determine the specified threshold performance, and choose a value of attenuation (including cable losses) that adds to roughly 5 to 15dB less than the system gain. For example, for the EX-2.4i, if the threshold for your measurement is -85dBm, the output power is +27dBm, so the system gain is 112dB. Choose a value of total attenuation in the range of roughly 100–105dB. Once this attenuation is inserted, verify RSL readings as in the first step, and then, using the GUI, reduce radio output power in 1dB steps until the receiving radio (the one whose output power not being adjusted) Link LED turns from green to yellow. This indicates that threshold has been reached. At this point, verify the equation for system gain using the new output power level setting and verify that the threshold performance is meeting or exceeding the published specification. Due to the variation of measurements and accuracies involved in this test, you may read a measurement that is 1dB to as much as 2dB off of the expected value. It should be of no concern unless the value is more than 3dB worse than expected. Once threshold is verified in this direction, repeat the process in the opposite direction by adjusting RF output power of the radio at the opposite end. Return the first radio to its original power setting before adjusting the second radio. Perform threshold measurement tests for all combinations of bandwidth and mode (modulation) being used–especially when troubleshooting. It should not be necessary to vary center frequency, as this does not have any appreciable impact on system gain performance, however, try any setting combination to gain confidence in the radio performance parameters.
Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 117 2007-01-03 DC Coupler for Antenna Alignment One challenge associated with an all-indoor radio construction is the alignment of the antennas. It can sometimes be challenging to place the radio near the antenna alignment personnel, and can also be challenging to run a separate set of wires for the voltmeter to be in view of the alignment personnel. If any of the conventional methods mentioned in the manual are difficult to achieve, one of the simplest methods to use is to employ the use of a DC coupling system as a temporary test configuration exclusively for the purpose of aligning the antennas. This type of system simply couples the DC voltage associated with RSL measurement at the radio location, over the RF transmission line, up to the antenna port. Remove all DC-blocked lightning arrestors in the transmission system prior to applying the DC coupler system. Failure to do so can result in electric shock and/or damage to the lightning arrestors and/or other equipment. Required Items The following items are needed for the DC coupling system, per radio end (double the quantities of these items for a complete link for simultaneous use at both ends): • 2ea DC couplers: mini-circuits ZNBT-60-1W • 1ea BNC male-male extension cable: Pomona 2249 • 1ea BNC female-to-mini Bantam (stackable Pin-tip plugs): Pomona 3221 • 1ea BNC female-to-banana male: Pomona 5268* • 1ea digital volt meter *This type of plug is typical for most professional hand-held digital volt meters (DVMs). However, verify that your DVM can accept this type of Bantam connector. If not, a different part number or adapter may be required to connect to the DVM. Interconnections Connect the items as shown in Figure 42. For the coupler installation, ensure that the DC side of the coupler is facing away from the radio and away from the antenna – towards the RF transmission line system. Using the BNC adapters and cables, attach the radio end DC coupler to the RSL port on the radio, and the antenna end DC coupler to the DVM that the antenna alignment personnel will use. The DC voltage from the RSL port is now coupled to the transmission line system between the radio and the antenna, and is available at the antenna location. This allows the antenna alignment personnel to view the DVM output directly while adjusting the antenna. ! CAUTION

Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 120 2007-01-03 Ethernet Connections There are two orientations of Ethernet connections. AUX has the securing tab towards the top of the connector while MAIN has the securing tab towards the bottom of the connector. Figure 44 illustrates the pin orientation and functionality of these connectors. Figure 44 Ethernet connectors (MAIN and AUX) The Ethernet connections implement Auto-MDIX, and therefore either ‘straight’ or ‘crossover’ Ethernet cables can be used, independent of the wiring of the connected device. Depending on the settings of in-band or out-of-band NMS, both the MAIN and AUX ports can access the far-end radio (if in-band) or not (out-of-band). In the case of out-of-band setting, only the AUX port can access the GUI, while only the MAIN port carries Ethernet traffic across the link.

Exalt Communications, Inc. Exalt i-Series Installation and Management Guide 5000001 124 2007-01-03 DIP Switch Settings (-16 Models Only) The ‘-16’ models incorporate a front panel DIP switch. Use the DIP switch for emergency configuration or restoration for installations where there is no computer available for complete radio configuration. Only use the DIP switch for temporary purposes, for the purpose of a bench test or antenna alignment. Use the Exalt GUI for complete system configuration, as required before final system deployment. The DIP switch is only read when the critical factory reset procedure is implemented (see Radio A/B Configuration on page 34 and Reset to Critical Factory Settings on page 52). That is, when the RMT button is pressed and held during power up, and held through the boot cycle (approximately 45 seconds, until LED behavior stabilizes). If changes are made while the radio is already powered or when power is not applied, the changes are not executed until a reset is executed. Figure 50 depicts DIP switch positions 1 through 8, left to right, when facing the front panel. Also, the switch is considered in the ‘One’ position when it is toggled upward, and in the ‘Zero’ position when it is toggled downward (default). Figure 50 DIP Switch Orientation Table 10 describes the function of each switch when placed in either position. Table 10 DIP Switch Functions Switch 0 (DOWN) 1 (UP) Position 1 Ignore all DIP switch positions If RMT button is held during boot cycle (reset to critical factory defaults procedure), reset to factory defaults, except IP address and password information, and make changes as described in this table.
