AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 3 of 129 PLEASE READ THESE SAFETY PRECAUTIONS!  RF Energy Health Hazard  Professional installation required.  The radio equipment described in this guide uses radio frequency transmitters.  Although the power level is low, the concentrated energy from a directional antenna may pose a health hazard. Use the following chart for determining the minimum safe distance.  Do not allow people to come within the minimum safe distance of the antenna while the transmitter is operating. Peak Gain of Antenna  Minimum  Safe Distance 18 dBi  20 cm 20 dBi  20 cm 23 dBi  25 cm 25 dBi  32 cm 30 dBi  56 cm 37.6 dBi  135 cm  Protection from Lightning  Article 810 of the US National Electric Department of Energy Handbook 1996 specifies that radio and television lead-in cables must have adequate surge protection at or near the point of entry to the building.  The code specifies that any shielded cable from an external antenna must have the shield directly connected to a 10 AWG wire that connects to the building ground electrode.

AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 11 of 129 2 Document Overview This document covers technical specifications and configuration information for the AB-Access system. It also covers some general troubleshooting steps to resolve issues that may occur while configuring or deploying the AB-Access system. This document should only be used as a reference for the 5.3.8 or newer System Software.
AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 12 of 129 3 AB-Access Overview 3.1 Topologies There are three topologies that are available with the AB-Access units CLIP, 1483 Bridging, and Native ATM. There are several configuration variations within these topologies but all will be referred by these names with an extension. 3.1.1 CLIP (RFC 1577) CLIP stands for Classical IP and is a routed topology. The AP or SU acts as a standard Layer 3 IP router, which means when data comes into the unit it analyzes the IP header and sends it out one of its interfaces based on the information in the header and its routing tables. It is important to note that only IP traffic can be passed over the units in this configuration. 3.1.2 1483 Bridging (RFC 1483) 1483 Bridging is a Layer 2 bridge, which will pass any valid Ethernet frame regardless of protocol. 1483 is also referred to as MPoA (Multi-protocol over ATM). The basic concept of how the bridge works is simple. It has two tables one for the terrestrial interface and one for the wireless interface. The terrestrial table stores all source MAC address it has learned from the terrestrial interface. It learns the MAC addresses by storing the source MAC address of any packet that has originated from a device on its terrestrial interface. If a packet is received that has a destination MAC address that is already in the table it will be discarded. The reason for this is if the destination MAC address is in the table it must mean that the device with that MAC address is on the terrestrial side of the radio. The wireless table works in the same manor except it learns the source MAC address of packets that have been received from the wireless interface. It is important to note that all broadcast packets will be sent over the link. It is also important to note that the implementation of 1483 bridging that the AB-Access system uses is LLC/SNAP encapsulation and we do not support the VC multiplexing implementation. 3.1.3 Native ATM Native ATM is a mode where both the AP and the SU act as an ATM switch. In this mode ATM cells are simply passed through the switching layer of the radio at layer 2. It is important to note that the AB-Access radio only supports PVC and not SVC.  3.1.4 PPPoA (RFC 2364) PPPoA is no longer supported.

Depending upon the required architecture, certain layers of this model may or may not be used.  Please note that both the wireless and terrestrial interfaces have access to all of the functions of the unit.  This is designed to allow the reader to understand where an incoming service is terminating and where its configuration is managed.  Management files (on Flashfs) for each layer are as follows: All: system.conf Routing Layer: resolve Bridging Layer: resolve, initbridge, initmr1483 or initr1483 Switching Layer: initswitchcli An E or A will indicate the Terrestrial interface type below the interface at the corner.  As an example, the diagram above shows an SU (on the left) with an Ethernet terrestrial interface and an AP (on the right) with an ATM interface.  The Wireless interface is always ATM. Additional services/clients such as NAT and/or DHCP will be depicted at the appropriate interface.

The ATM switch used for illustration purposes is the FVC Access NGI. The switch used for the troubleshooting screenshots represents FVC software version 5.07. Some of the commands for older FVC switch software are different. 4.3 Subnetting Subnetting within the AB-Access radios is done in hexadecimal format. There for it is necessary to know the decimal to hex conversions for commonly used subnets. CIDR notation is also used to define the subnets in all the diagrams, so refer to the chart below for any questions on subnetting.  Decimal Subnet  HEX Subnet  CIDR 0 00 /24 128 80 /25 192 C0 /26 224 E0 /27 240 F0 /28 248 F8 /29 252 FC /30  4.4 Peak Cell Rate - PCR The Peak Cell Rate is policing not pacing, there for it will discard all cells received over the limit and not buffer them. This means the cells will be have to be retransmitted via an upper layer protocol. To calculate the Peak Cell Rate you simply divide the desired bandwidth by the number of bits in an ATM cell. An ATM cell is 53 bytes consisting of a 5-byte header and a 48-byte payload. In the following example, the PCR for a 1 Megabit circuit is calculated.  PCR values are rounded to the nearest integer. 1024000 bps/(48 bytes-per-cell*8 bits-per-byte) = 2667 The following table lists PCR values for several, common data rates.

Even if they are covered, you will probably want to add settings that are specific to your network. To do this you can edit the individual files and rupee them to the units. This is not meant to replace the upgrade script.  It is only meant to send individual configuration files to a unit.
AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 16 of 129 You can send individual files from DOS or LINUX; unlike the upgrade scripts. The reason for this is that the upgrade script is using expect scripting and can only be run from a Unix based OS. One note about the rupee-dos is that it can only be run be a true DOS based OS (Win95 or Win98 not NT). NT uses a Virtual DOS Machine (NTVDM) and will not work with the rupee-dos command. WARNING If you rupee a file or files to a unit and do not reboot the unit, and then rupee another file or files to the unit only the last set of files will be saved to the flash.  4.6.1 LINUX 1.  Make sure you can ping the unit that you want to send files to. 2.  Change to the directory that the configuration files are in. The rupee-unix file must also reside in this directory. 3.

Make sure all of your configuration files are correct if you use this option. When the unit reboots, changes are final. 4.7 RTFD (Return To Factory Default) The new Return To Factory Default (RTFD) feature allows IP connectiviey to be established with units that have unknown or invalid configurations. Using this feature, the AB-Access unit wil adopt a known IP configuration enabling Command Line Interface access via telnet through the physical Ethernet interface. Following a restart or power up, the AB-Access/AB-Extender units will listen for 1 second for a proprietary coded UDP packet on their Ethernet interface; adopting the appropriate IP configurations as indicated below.  If the unit receives the UDP packet, it will retain the active configuration for 30 minutes, after which the normal start-up procedures will continue with the IP and interface configuration taken from the unit’s Flash files. If during the 30 minute period, a subsequent coded UDP packet is received, the timeout will be restarted.  NOTE On Windows 2K and XP you may need to disable the auto media sense. Some NICs will be capable of disabling this feature from their configuration parameters. If this option is not available on your NIC you will have to add a registry entry. Axxcelera has created a reg edit that can be installed by simply double clicking on the media-sense.reg file. Or you can enter the following register key via regedit. [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters] "DisableDHCPMediaSense"=dword:00000001  4.7.1 RTFD IP Configurations  Ethernet Interface Access:    IP Address    192.168.3.254     Netmask  255.255.255.0     Default Route  192.168.3.1

Recover-unix  -  For use with Linux installations utilizing glibc 2.1.3. 4.7.3 Procedure to restore the default configuration 1. Connect a PC (Windows or Linux) to the wallbox of the unit, ensuring that there is appropriate connectivity at the physical and IP levels. 2. Start the recovery utility. A sequence of dots will be displayed to indicate successful network transmissions. [root@temp SU_TEMPLATE]# ./recover-unix ethernet SU/AP recovery client  ……………………………..  3. Restart the AB-Access unit. 4. When the recover utility terminates, the AB-Access unit has been successfully configured and can be contacted over the physical interface via a telnet session.  5. It is best to do a full system upgrade after a unit has been recovered to a state that IP connectivity is regained. This will insure the unit will function properly once redeployed.   4.7.4 Disabling the RTFD Feature RTFD can be disabled by writing a file to flash with the name “no_rtfd”. The file must be a text file; i.e. only containing ASCII characters. A suggested first line for the file is “disable RTFD” – though the actual content of the file will not be referenced: only the presence or absence of the file is significant.   4.8 Web Page The web page can be used look at channels that are available for use, and determine the quality of the current channel.

The "survey scan" CLI command and 'radio survey' web page now provide additional data on RF energy in each channel.  Continuous or bursty energy can be detected, regardless of the source (i.e. it does not have to be Axxcelera equipment), providing it is present during the scan.  However, the RF-energy-scan process interrupts normal service for the entire duration of the scan. Survey results are saved in a temporary file called "ap_scan" or "su_scan", as appropriate.  The file contains results of the last scan to be performed, and is overwritten by a new scan.  The file is normally lost when the unit reboots, but the file is saved if a "config save" is performed, or if the unit is upgraded.  Therefore, it is now possible to use the "survey scan" command remotely, i.e. executing on an SU via the RF link.   This feature can be used at the time of unit installation, or when trying to investigate and mitigate an interference problem.  It can also be used before performing a sector channel change to look for potential interference problems.
AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 21 of 129 When performed on an AP the sector itself is quiet, so any RF energy detected must be coming from other sources.  However, when a scan is done on an SU the AP and other SUs may still be transmitting.  This may confuse the results.  The RF energy from other units in the SU's sector will be detected on-channel, but will also appear to a lesser extent in adjacent channels (e.g. 23dBm lower than in the main channel).  This should be borne in mind, and if necessary the scan should be performed with the AP transmitter disabled, which will silence that sector (e.g. using "hmm modem rf disable/enable"). 4.10  Static Channel Scanning This is a static-mode feature to simplify channel-changing.  The feature is implemented on SUs, and all SUs must be running 5.3.x software before this new method of channel-changing is used, otherwise SUs will be lost when the AP is manually forced to change channel.  Note that the AP must also be running 5.3.x, so that the BID can be set to a non-zero value.  This feature is controlled by the BID and channel mask parameters. If the BID is set to zero then the static-mode channel-scanning function is disabled.  If the BID is set to non-zero then the channel-scanning function is enabled on the SU.  On booting up the SU channel and antenna are determined by the system.conf file. A scan is initiated if the received Frame Descriptor Header (FDHDR) error rate is greater than 90% for a rolling 3 minute period. Therefore the SU will not scan until at least 3 minutes after booting-up, nor for 3 minutes after losing its AP.  This delay allows a reboot of the AP (even an FPGA AP with the old v2.7 Boot ROM) without causing the associated SUs to scan.  The SU will only scan the channels defined by the channel mask, and will only detect APs with the same BID.  When the scan is complete the SU will lock to the channel/antenna that gave the best AP signal (same BID).  The SU will choose error-free channels in preference to errored ones, and will then select the best signal level.  The new channel and antenna are then automatically saved to the system.conf file, so on rebooting the SU will start-up with the new channel and antenna settings.  Note that the current values of all parameters are saved to the system.conf file, not just the channel/antenna parameters.  If the SU does not detect any suitable signal it will revert to the channel/antenna it was on before the scan.  A further scan will occur after 3 minutes if an AP is not detected.  The channel mask can be changed with the "hmm system mask" command, and the "hmm radio channels" command can be used to confirm which channels will be scanned.  Until now the BID parameter in the system.conf file has been ignored by the software and a value of zero has been used.  The 5.3.x software uses the BID value defined in the system.conf file.  The BID can also now be viewed and changed with the new "hmm system bid" command.  SUs can only see APs with the same BID, so all units in a sector must have the same BID.  If a unit receives a signal from another unit which has a different BID value then only the errors from that signal appear in the MAC stats. Valid data with the wrong BID is discarded by the receiving MAC, and does not appear in the MAC stats.  To change the channel of a static sector using this new feature, all units must be running 5.3.x software, must have the same non-zero BID, and each SU must only be able to see one AP with that BID (on all channels defined by their channel mask).  The channel mask on each SU should be set appropriately, e.g. scanning all channels that are likely to be used.  To change the channel of the
AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 22 of 129 sector, simply change the channel of the AP and wait for the SUs to scan and lock on again (i.e. after 3 minutes plus the duration of a scan).  If some SUs fail to regain contact with the AP due to an issue on the new RF channel then simply change the AP back to the original channel and the SUs will regain contact after a short period (i.e. after 3 minutes plus the duration of a scan). 4.11 PTP Power Control This feature makes point-to-point links more robust, by increasing the signal power received at the AP.  The AP then has a higher tolerance to noise and interference.  When enabled on both units, both the AP and SU transmit at full power, and both the AP and SU adjust their receiver gain according to the signal power received. This means that the AP receiver has a similar RSSI to the SU, rather than a level of -74dBm as with standard power control.  For example, if the backhaul SU has an RSSI of -65dBm then the backhaul AP will also have an RSSI of approximately -65dBm, 9dBm higher than with the normal power control scheme. A unit's power control mode (i.e. standard or PTP) is determined by the new "ptp" parameter in the system.conf file (see section 3.1 for details).  This parameter can be viewed and changed with the new CLI command "hmm system ptp enable/disable" or via the system.conf file. Both ends of a point-to-point link must be operating in the same power control mode for the link to work.  Point-to-multipoint sectors cannot use the new PTP power control mode.  If enabled on a point-to-multipoint sector it will sever communication between the AP and the majority of SUs. When an AP is operating in the new PTP power control mode the "hmm modem rssi" command becomes meaningful at the AP, and the "hmm modem txpower" command shows extra information. The new PTP power control mode should be used with care, ensuring that the boosted upstream signal will not affect other units, i.e. with units co-located with the point-to-point AP or SU.
AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 23 of 129 5  RF Design and Planning 5.1 Overview The AB-Access system is a communications system using wireless technology in the U-NII, ISM and ESTI frequency bands. Therefore understanding Radio Frequency (RF) system design is necessary to ensure gook link quality and, thus, good system performance. This section discusses the basics of RF Design and Planning from the perspective of deploying the AB-Access System.  5.2 The U-NII, ISM and ETSI Channel Plan In 1997 the FCC amended its Part 15 rules to make 300 MHz of spectrum available for high-speed wireless digital communications with unlicensed operation. This band, called the Unlicensed National Information Infrastructure or U-NII band, provides the spectrum at 5.15 to 5.25 GHz for indoor use, and 5.25 to 5.35 and 5.725 to 5.825 GHz for outdoor use. The peak output power permitted is limited to 23 dBm EIRP in the lower (indoor) band, 30 dBm in the mid-band, and 36 dBm in the upper band.  The 5.8 GHz ISM (Industrial Scientific and Medical) band ranges from 5.725-5.850 GHz. Which is an unlicensed frequency limited to 36 dBm for PTMP equipment. The limit for PTP is higher than PTMP.  The 5.8 GHz ETSI (European Telecommunications Standard Institute) variant consists of two bands (5.725–5.795 GHz and 5.815–5.850 GHz).  These are unlicensed, limited to 2 Watts EIRP (3 dBW) and 100mW/MHz PSD.  NOTE:  AB-Access uses both the U-NII and ISM band for its upper band channels. NOTE:  AB-Access uses a different channel scheme for ESTI bands.  NOTE: BPSK modulation is only approved by the FCC for the upper band channels.  5.3 Air Interface The SU talks to the AP over a proprietary airlink protocol on a single 15 MHz channel using QPSK or BPSK modulation and a technique called Time Division Duplex (TDD). Both upstream and downstream traffic time-share this channel.
AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 24 of 129 5.4 Wireless MAC When data is sent over the wireless link it must first be put into a structure that each end unit will understand. The hardware that does this is called the MAC (Medium Access Controller). RGFDHDR DACK DCELLATT STT RR UACK UCELL/UCELLR 5.4.1 Downstream burst 5.4.1.1  Access Point Turnaround Time (ATT) AB-Access system is TDD (Time Division Duplexing), meaning that the AP and SUs transmit and receive on the same frequency. It is therefore necessary to have a small delay between the transmit and receive processes, because it is using the same hardware to perform both functions. 5.4.1.2  Frame Descriptor Header (FDHDR) Downstream bursts begin with a Frame Descriptor Header (FDHDR) this portion of the MAC frame is seen by all SUs in that sector. The FDHDR contains a map of all traffic upstream and downstream, to occur within the MAC frame. This is why you assign a unit a MID, when an SU sees an FDHDR it looks for its MID in the FDHDR to see if it is going to receive any cells. If it does not see its MID it will ignore the rest of the frame. 5.4.1.3  Reservation Grant (RG) The next field in the downstream burst is the Reservation Grant Response (RGR). An RGR is a response to a Reservation Grant Request (Upstream Burst). The RGR acknowledges a request and tells the SU that it can transmit on the upstream burst.

AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 25 of 129 5.4.1.4  Downstream Acknowledgement (DACK) The Downstream Acknowledgement (DACK) is an acknowledgement sent from the AP, which contains bit maps corresponding to the success or failure of individual cells sent to an SU in the previous frame. If any cells were missed or dropped they will be resent in the next frame. 5.4.1.5  Downstream Data Cells (DCELL) The Data Cells are the actual ATM cells that contain data. The maximum ATM cells per frame are 32. The maximum ATM cells that can be sent to an individual SU is 6 per frame. 5.4.1.6  Subscriber Turnaround Time (STT) AB-Access system is TDD (Time Division Duplexing), meaning that the AP and SUs transmit and receive on the same frequency. It is therefore necessary to have a small delay between transmit and receive processes, because it is using the same hardware to perform both functions. There is also a set delay for each individual SU. This delay in turnaround is to compensate for propagation delay.  5.4.1.7  Reservation Request (RR) The Reservation Grant Request (RR) is a request sent by the SU to the AP when it has data to send. The RGR is a contention based request, meaning it performs like an Ethernet network were there is no guarantee that it will be received by the AP on the first try. This would happen when another SU wants to transmit at the same time and would cause a collision. If a collision occurs the SU will try again until it is acknowledged with a Reservation Grant Response. 5.4.1.8 Upstream Acknowledgement (UACK) The Upstream Acknowledgement (UACK) contains bit maps corresponding to the success or failure of individual cells from an AP. If any cells were missed or dropped they will be resent in the next frame. 5.4.1.9 Upstream Cell (UCELL/UCELLR) The UCELL’s are the actual ATM cells that contain data. The maximum ATM cells per frame are 32. The maximum ATM cells that can be sent to an AP by an individual SU is 6 per frame. The UCELLR is a data cell that also has a Reservation Grant Request if the SU has more than 6 data cells to send. The reason for this is so that the SU doesn’t have to contend for another Reservation Grant in the contention slot. 5.5 Delay Compensation During the upstream portion of the MAC several SUs transmit in sequence. Since SUs are separated from the AP by anywhere from 0m to 16km, there is a wide range of propagation times for the full path for the AP to the SUs and back. In order for the SUs transmissions to arrive at the AP properly aligned, some active compensation of propagation delay is performed. An SU must delay
AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 26 of 129 compensate before it can transmit data, if it was allowed to transmit without delay compensating it would confuse the AP because it would be receiving cells out of order.

The AB-Access implementation of the TDD architecture allows the TDD frame to dynamically vary in size according to the offered load: short frames when fewer users are sharing the channel, longer frames when there are many simultaneous users. The TDD guard time is also adaptive, as it is set to round trip propagation delay to the farthest SU. TDD has a number of advantages over a FDD system.

AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 28 of 129 • Spectral Efficiency – TDD can be deployed using less spectrum than a comparable FDD system. A single TDD channel can be deployed per sector instead of two channels needed for FDD. Likewise, a multi-cell deployment can be installed using a total of three RF channels (both polarizations), whereas FDD needs four to six channels.  • Complexity – Since each transceiver is wither transmitting or receiving, but never both at once, a single RF front end can  be shared reducing the radio complexity. • Power Control – In cellular systems, where channels are reused many times throughout the system in order to increase capacity, the highest efficiency is realized when the power in each direction can be minimized. This reduces the amount of energy that is ‘leaked’ into surrounding areas, which appears as interference. In FDD systems, it is quite difficult to accurately control the channel’s power since a feedback path is required. No such path is needed in a TDD system since the same channel is used in both directions. The SU needs to only measure the received power from the AP in order to know how much to attenuate its upstream transmission.  • Channel Efficiency – Because each frame carries upstream and downstream traffic in proportion to the offered load in each direction, adaptive TDD systems are highly efficient in its use of bandwidth. FDD systems have to make an estimate of the traffic mixture and allocate channel bandwidth accordingly. As shown in the chart below, any variation from this estimate (in this case 15:1 downlink) will result in wasted bandwidth. This variation is inevitable due to the diurnal variation of business usage during the daytime hours, residential usage in the afternoon and evening, a varying mixture of user types according to the geographic location, and an ever-changing set of user applications.   5.8 AP and SU Specifications 5.8.1 AP/SU/Extender Functional Block Diagram The Access Point and Subscriber Unit functional block diagram is shown below.

AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 33 of 129  5.9 Topology Types To properly deploy the AB-Access System, one must understand the geographical physical topology. While the real world possibilities are endless, the following three distinctive geographic topologies will be covered: • Macrocells • Microcells • Picocells A Macrocell design should be used when you are trying to provide ubiquitous coverage over a large area. Each cell has many Subscribers. The fundamental limit in deploying in this manner is usually coverage zone (cell radius) due to U-NII, ISM & ETSI EIRP limits, as well as building and terrain obstructions. A Microcell is normally used when you are trying to provide high-density coverage to a smaller geographic area. Each cell sector has many subscribers per sector. The fundamental limit in deploying in this manner is co-channel interference due to LOS interference paths. A Picocell design normally covers an extremely small geographic area such as a neighbourhood or a Multiple Dwelling Unit (MDU) complex. There are normally many
AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 34 of 129 sectors and few subscribers per sector. The fundamental limit in deploying in this manner is Line of Sight (LOS) coverage. While the above are generalizations, they can be used effectively as a starting point for developing an RF plan for deployment. However, based upon the specifications of the AB-Access equipment, it is necessary to have some pre-defined RF coloring schemes. To better understand the benefits of different coloring schemes, a basic concept of interference types should be understood. 5.10 Interference Types There are four distinct types of interference that can occur in a cellular reuse pattern. Each unique in its geometry and imposes unique frequency reuse constraints.  EFFECT INTERFERENCE TYPE Would affect only the one SU. Could affect other units if they are in the same area.  Type 1 – Downlink Downlink to Subscriber Unit Interfered with by another Access Point transmission.  Would affect only the one SU. Could affect other units if they are in the same area. Type 2 – Downlink  Downlink to Subscriber Unit Interfered with by a Subscriber Unit Uplink in another cell. Would affect all units in the sector.  This would be a constant source of interference.  Type 3 – Uplink  Uplink to Access Point Interfered with by another Access Point transmission. Becomes critical if facets using same frequency face each other. Would affect all units in the sector. Could be an intermittent problem based on the amount of data that interfering SU is transmitting.   Type 4 – Uplink Uplink to Access Point Interfered with by a Subscriber Unit uplink from another cell.  Hardest to eliminate and will reduce the performance of the whole system.
AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 35 of 129 5.10.1 Type 1 Interference Downlink to Subscriber Unit interfered with by another Access Point Downlink. All Access Points power control for full service at the sector edge (in cusp). The worst case scenario is when the SU (Cell 1) has the interfering AP at Boresight (Cell 2) and is towards the edge of its sector, i.e. min CNR from its AP.           5.10.2 Type 2 Interference Downlink to Subscriber Unit interfered with by a Subscriber Unit Uplink in another cell. Worst case scenario is interfering SU at range (max Tx power), and victim SU at range (lowest CNR) and SUs facing each other, e.g. Cells 1 and 3. The interference is reduced if SUs using the same frequencies do not face each other, e.g., Cells 1 and 2.      Cell 1 Cell 2 Interfering AP Interference hCell 1 Cell 2 Weak Interference path Cell 3 Strong Interference path
AB-Access Config & User Guide  5.5  Axxcelera Broadband Wireless July 27, 2004  Company Confidential  Page 36 of 129 5.10.3 Type 3 Interference Uplink to Access Point interfered with by another Access Point Downlink. This is only an issue if sectors using the same frequency face each other in the reuse pattern, e.g., Cell 1 and Cell 3. Otherwise it is a benign interference type, e.g., Cell 1 and Cell 2.       5.10.4 Type 4 Interference Uplink to Access Point interfered with by a Subscriber Unit Uplink in another cell. This is the worst case of intercell interference, as one SU, e.g., in Cell 2, interferes with all the users on the same frequency and polarization in Cell 1 (whenever the SU in Cell 2 is transmitting).  As the system has power control for SUs, the worst case Type 4 interference will be caused by SUs deployed at range and at the edge of their sector, i.e., in the Access Point Antenna Cusp.

Check all physical connections.  The radio is a network device, which means if you connect it to a PC (NIC) you will use a straight-through cable.  To connect the radio to a network device (hub, switch, router) use an Ethernet cross-over cable (1-3, 2-6).  It is also important to check that the cable is punched down correctly in the wall box and that the cable is terminated correctly at the radio.  The termination at the radio uses 568B (wo,o,wg,bl,wbl,g,wbr,br). 2.  Make sure the computer you are pinging from is on the same network as the AP. If you are on a different network than the radio make sure you have the proper routes in the radio and the computer you are trying to ping from. 7.3.4.2  Can’t ping across the wireless link There are numerous reason why you couldn’t ping across the wireless link. After following these troubleshooting steps and you still can’t ping across the wireless link refer to the RF troubleshooting document. 1.

This means that the AP will pass ATM cells at layer 2, and the SU will act as a router analyzing all data at layer 3 and based upon destination IP address forward the data out the proper interface.  In static mode you can configure the management traffic in either routed or a switched configuration. Each section describes the pros and cons of each configuration so you can decide which is best for your network.  8.1 Static CLIP_S (routed management) All assumptions for troubleshooting CLIP_S (routed management) are based on the following diagram. 192.168.100.3PVC 768RLBLSLARLBLSLEATM SwitchPCRouter192.168.5.1192.168.2.34 /27192.168.100.1192.168.3.65 /29MID 0 MID 3192.168.2.50 /27LANPVC34PVC 769PVC200192.168.5.5AP Management PVCSU Management PVCSU Data PVC 8.1.1 Routed Management PRO/CON CLIP_S can be configured with switched management or routed management.

It is important to understand that in this configuration data can only go from SU-AP & AP-SU within the sector. Data will not be able to from SU-SU within the same sector. This can only be done by connecting a router to the AP and redirecting that traffic back to the AP.  10.1 Static 1483_T All assumptions for troubleshooting 1483_T will be based on the following diagram.

Check all physical connections. The radio is a network device, which means if you connect it to a PC (NIC) you will use a straight cable. If you connect the radio to a network device (hub, switch, router) you will use a Ethernet cross-over cable(1-3, 2-6). It is also important to check that the cable is punched down correctly in the wall box and the cable is terminated correctly at the radio. The termination at the radio uses 568B (wo,o,wg,bl,wbl,g,wbr,br). 2.  Make sure the computer you are pinging from is on the same network as the AP. If you are on a different network than the radio make sure you have the proper routes in the radio and the computer you are trying to ping from. 10.1.3.2  Can’t ping the radio across the wireless link. There can be numerous reasons why you can’t ping across the wireless link. After following these troubleshooting steps and you still can’t ping across the wireless link refer to the RF troubleshooting document. 1.  Check the 1483 processes in the radios.

Check all physical connections. The radio is a network device, which means if you connect it to a PC (NIC) you will use a straight cable. If you connect the radio to a network device (hub, switch, router) you will use a Ethernet cross-over cable(1-3, 2-6). It is also important to check that the cable is punched down correctly in the wall box and the cable is terminated correctly at the radio.  The termination at the radio uses 568B (wo,o,wg,bl,wbl,g,wbr,br). 2.  Make sure the computer you are pinging from is on the same network as the AP. If you are on a different network than the radio make sure you have the proper routes in the radio and the computer you are trying to ping from. 12.1.3.2  Can’t ping the radio across the wireless link.

Check all physical connections. The radio is a network device, which means if you connect it to a PC (NIC) you will use a straight cable. If you connect the radio to a network device (hub, switch, router) you will use a Ethernet cross-over cable(1-3, 2-6). It is also important to check that the cable is punched down correctly in the wall box and the cable is terminated correctly at the radio.  The termination at the radio uses 568B (wo,o,wg,bl,wbl,g,wbr,br). 2.  Make sure the computer you are pinging from is on the same network as the AP. If you are on a different network than the radio make sure you have the proper routes in the radio and the computer you are trying to ping from. 13.2.3.2  Can’t ping the radio across the wireless link. There can be numerous reasons why you can’t ping across the wireless link. After following these troubleshooting steps and you still can’t ping across the wireless link refer to the RF troubleshooting document. 1.  Check that SU has the proper MID. 192.168.3.10 hmm>   system   mid MID 3  2.  Check the ipatm pvc is correct in relation to the MID and remoteip
