MBSC-C RU MBSC-C RU December 15, 2015 Page 43 System Overview and Unit Description 3.1 System Overview The MBSC1900-040-RU system is a multi-operator, multi-band and multi-technology coverage system that provides in-building / venue coverage for up to five operating bands. Large buildings typically interfere with the transmission or reception of cellular phone system signals by imposing high attenuation losses on the RF signal. The mBSC system is designed to overcome these losses which otherwise make cellular communications within buildings or structures difficult or impossible. With the mBSC system, cellular phone RF signals can be distributed to the interior areas of any building or structure to eliminate dead spots and improve reception. The MBSC1900-040-RUcoverage solution interconnects to, and extends, the wireless service provider base station equipment (BTS) and service antennas. A functional overview is illustrated below. Figure 3mBSC System Functional Overview The mBSC system provides downlink signal amplification and uplink sensitivity improvement for multi-band RF signals, which may be comprised of multiple carriers and multiple standards. The Host Unit provides the input interface for RF signals from a base transceiver station (BTS). The Host Unit converts the RF signals into a digital format and distributes the digitized signal over fiber to multiple output ports. An optional Multi-operator Point-of-Interface (POI) combines multiband BTS inputs from several operators into a single TXin / RXout interface to the Host Unit. Refer to “SP-MBSC-C-POI” for additional details. The Remote Node receives the optical signals from the Host Unit, converts the signals back into RF and interfaces with the service antennas to amplify the RF signals throughout the building. The Remote Node is typically wall-mounted within an equipment room. 3.1.1 Interface with BTS The Host Unit is typically installed close to the wireless service provider BTS equipment. In the downlink path the Host Unit combines RF signals from up to 5bands and feeds the combined signal to a fiber-optic
MBSC-C RU MBSC-C RU December 15, 2015 Page 5transceiver for transmission to the interconnected Remote Node(s).In the uplink path the Host Unit converts a composite multi-band optical signal into independent RF signals for interconnection with the BTS receive elements. 3.1.2 Interface with Cellular Phones The mBSC Remote Node interfaces with the cellular phones through the service antennas. In the reverse path, the Remote Node receives RF signals from cellular phones. In the forward path, the Remote Unit transmits the RF signals to the cellular phones. A bi-directional antenna is connected to the mBSC Remote Node to transmit and receive RF signals from the cellular phones. 3.1.3 Fiber Optic Transport The Host Unit is connected to each Remote Node over a single optical fiber. The optical fibers must be terminated withE2000/APC connectors for connection with the Host Unit and the Remote Node. 3.1.4 Powering The Host Unit is powered by -48V DC which is supplied by either the equipment room power distribution cabinet or an AC/DC converter. The Remote Node is powered by 110/220VAC, 50/60Hz power which is supplied through a power supply distribution junction box. 3.1.5 Cooling The Host Unit is cooled through cross-convection without fans. The Remote Node contains multiple single-band Remote Units, which are cooled through continuous air flow fans mounted on the top of each singe-band unit. A minimum of 200mm (7.87 inches) of clearance space must be provided on both the top and the bottom sides of the Remote Node for air flow. An alarm is provided that indicates if a high temperature condition occurs. 3.1.6 Fault Detection and Alarm Reporting LED indicators are provided on the front panel of the Host Unit to indicate if the mBSC system is operating as expected (normal) or if a fault is detected. In addition, normally open and closed alarm contacts (for both major and minor alarms) are provided at the Host Unit for connection to a customer provided external alarm system. The mBSC system also includes a standalone (optional) Element Management System server, which interconnects with each Host Unit in a multi-system deployment, and is used for system configuration, status monitoring, and SNMP alarm reporting / management. 3.2 Host Unit Description As shown in Figure 4, the Host Unit is a standard 19”4U rack-mounted shelf, which serves as the BTS servicing unit for the mBSC system. The Host Unit provides the following basic functions:

The EMS local GUI is a web-based application supported by standard web-browsers. Microsoft Internet Explorer® is recommended. System configuration and monitoring can also be performed from a remote EMS Server. The EMS Server is a multi-user platform that includes enhanced management capabilities for configuration, monitoring and alarming. The EMS Server is required to generate SNMP alarms. Note:It may take up to 3 minutes for the mBSC system to initialize, therefore it is recommended to only attempt to login to the GUI after the mBSC system has completely started, otherwise the GUI may incorrectly display a message indicating that the username and/or password are wrong (when in fact they may be correct). 5.1.1 Using Ethernet Port Access to the EMS Local GUI through an RJ-45 Ethernet connection is provided on the RCU card in the Host Unit shelf. The Ethernet port is the primary point of connection for the remote EMS Server. The EMS Local GUI accessed through the Ethernet port is assigned the IP address 172.18.60.60 at the factory. However, this IP address can be modified to suit the networking requirements of the installation (e.g. to allow access across a Local Area Network). Steps: 1. Obtain a CAT5 cable and connect it to the RJ45 port on the host unit RCU card, and connect the other end into the RJ45 port on the laptop/computer. Depending on the model year of your computer, a crossover cable may be required. 2. Start an Internet Explorer browser session on the laptop/computer, and enter the following URL to connect to the Local GUI–“http://172.18.60.60”. Note: The mBSC system does not provide DHCP service. To access the GUI you will need to configure the local computer with a static IP address the same subnet as the local GUI. Note: The EMS Local GUI is a single-user interface, and supports only a single user at a time. If the Ethernet interface is connected to a Local Area Network, and more than one user is accessing the EMS Local GUI at the same time, inconsistent operation may occur. Please use the EMS Server for multi-user applications.
MBSC-C RU MBSC-C RU December 15, 2015 Page 44 5.1.2 Using USB Port Access to the EMS Local GUI through a standard USB connection is also available at both the Host Unit RCU card, and the CM-BTS enclosure of the Remote Node. The EMS Local GUI has a fixed IP address assignment when accessed through the USB port – it is set at the factory and cannot be changed. Steps: 1. Install the USB-Ethernet driver on the laptop/computer. The laptop/computer must be connected to the internet in order for the drivers to be automatically installed. 2. Obtain a USB cable and connect it to the USB port on the host unit and the laptop/computer. 3. Start an Internet Explorer browser session on the laptop/computer, and enter the following URL–“http://192.168.5.220”. Note: The mBSC system does not provide DHCP service. To access the GUI you may need to configure the local computer with a static IP address the same subnet as the local GUI.

The nominal downlink input to the BIU (TXin) is 0 dBm±1dB (range: -10dBm to +10dBm). If the BTS signal downlink exceeds +10 dBm, or the signal is a composite duplex RF signal, then RF signal conditioning will be required. BTI provides a high-power Point of Interface to perform RF signal conditioning (mBSC-C-POI) The use and operation of this component is outside the scope of this document. 5.4.2 Set Downlink Gain It may be necessary to adjust the Downlink gain of the mBSC-C system in order to achieve a balanced forward and reverse link, or to adjust for other conditions (input levels from the BTS, propagation characteristics at different bands, specific RF design). The MBSC1900-040-RU provides two points of adjustment for downlink gain: 1. Software controlled attenuator for each band in the BIU 2. Software controlled attenuator in each band-specific Remote Unit The determination of appropriate values for these parameters is outside the scope of this document. 5.4.2.1 Adjust BIU Downlink Attenuator Adjust the BIU downlink value for each frequency band as follows: 1.

By injecting an RF CW signal at each TXin port of the BIU the end-to-end downlink system gain can be verified without additional test equipment required at the Remote Node. Verify the end-to-end Downlink Gain for each frequency band as follows: 1. Using an RF Signal generator inject a CW RF signal to the TXin port of the BIU a. Set the frequency to the center of the spectrum to be used in the system (if the operator licensed bands are not known set the frequency to center of the band – e.g. 2132.5 MHz for AWS band) b. Set the input RF power level to be 3 – 5 dB below the expected RF level to product maximum output power at the RU to avoid accidental overdrive (e.g. if the gain is set so that 0dBm input will produce +43 dBm at the output then start with -5dBm) 2. The resultant Downlink output power of the RU can be observed in two ways: a. In the topology window the Downlink Output power is displayed next to the specific RU (e.g. 30.7 dBm indicated in the topology diagram by the 800MHz RU in Figure 53 – Up/Down Link Verification ) b. Downlink Output Power: In the component window 3. Variations in filtering, amplifiers, and optical loss may cause the actual system gain to vary +/- 6 dB. All paths can be normalized by adjusting downlink attenuation settings in the BIU. 4. This procedure should be repeated for each frequency band in the system

MBSC-C RU MBSC-C RU December 15, 2015 Page 68 6 Maintenance Note: Check your sales order and equipment warranty before attempting to service or repair the mBSC-C system. Breaking the seals on equipment under warranty will void the warranty. Do not return equipment for warranty or repair until proper shipping instructions are received from the factory. 6.1 Electrostatic Discharge Precautions The mBSC-C system modules contain assemblies and components which are sensitive to electrostatic discharge (ESD). Carefully observe the precautions and recommended procedures to verify that system reliability is not compromised due to component damage from static electricity. The following precautions will significantly reduce the risk of system failure or malfunction due to ESD: 1. Always wear a grounded wrist strap while working around the system 2. Consider all assemblies, components and connections to be ESD sensitive 3. When unpacking circuit boards, interfaces and modules that are packaged separately from the system, keep them in their conductive wrapping until they are ready to be installed. 4. Before removing or replacing any components, select a work area where potential static sources are minimized 5. Handle circuit packs and boards by the grounded housings, avoiding contact with the connectors 6.2 Preventative Maintenance The mBSC-C system requires minimal regular maintenance to ensure continuous and satisfactory operation. Maintenance includes diagnosing and correcting the service problems as they occur. When an alarm is reported, it is necessary to follow a troubleshooting procedure to identify the source of the problem. The following are recommended routine maintenance procedures:  Check the indicator status LEDs (normal or alarm).  Prevent dust or grime from accumulating on the surface of heat sinks.  Check power output. 6.3 Fault Detection and Alarm Reporting The mBSC-C on-board embedded firmware detects unit and system faults and reports them as system alarms. The following methods may be used to report alarms:  Dry-contact alarm points  Status LEDs on system components  NMS (Local GUI, remote NMS, and SNMP Alarms)
