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 GUIhttp://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. MBSC0700-040-RU Page 43 April 15, 2013 5.1.2 Using USB Port MBSC0700-040-RU 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 URLhttp://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. MBSC0700-040-RU Page 44 April 15, 2013 5.1.3 Login to EMS Local GUI Access the EMS Local GUI as follows:
MBSC0700-040-RU 1. Type the appropriate URL into the browser (e.g. http://192.168.5.220 for USB port). The dialog box shown in Figure 40 EMS Local GUI Login will appear. 2.

For more information about support for SNMP please refer to UM-MBSC-C-EMS. 5.4 System Tuning 5.4.1 BTS Signal Conditioning The interface from the operator BTS equipment to the MBSC0700-040-RU is via simplex RF connections to the BIU. The nominal downlink input to the BIU (TXin) is 0 dBm1dB (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 MBSC0700-040-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. Click on the BIU in the topology diagram and the component window will pops up on the right as shown in Figure 50 - BIU Attenuator. 2. Downlink Attenuation Value (XXX MHz): Input the appropriate value for each frequency band (0dB 25dB range) 3. Click Save MBSC0700-040-RU Page 57 April 15, 2013 Note that the system will report an error message if the input value is out of range.

The MBSC0700-040-RU provides two points of adjustment for uplink 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. 5.4.3.1 Adjust BIU Uplink Attenuator Adjust the BIU uplink attenuation value for each frequency band as follows:
1. Click on the BIU in the topology diagram and the component window will pops up on the right as shown in Figure 50 - BIU Attenuator. 2. Uplink Attenuation Value (XXX MHz): Input the appropriate value for each frequency band (0dB 25dB range) 3. Click Save 5.4.3.2 Adjust RU Uplink Attenuator Adjust the RU uplink attenuation value for the specific RU / frequency band as follows:

Uplink Attenuation Value: Input the appropriate values (0dB 25dB range) 3. Click Save MBSC0700-040-RU Page 60 April 15, 2013 5.4.4 Link Verification MBSC0700-040-RU The MBSC0700-040-RU system is equipped with features that enable the downlink and uplink link to be fine-tuned from the head-end location using common test equipment (RF signal generator and RF power detector). 5.4.4.1 Verify End-to-End Downlink Gain Each RU in the remote node is equipped with a calibrated Downlink Power Detector which will display the average power at the output of the RU. 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 52 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 MBSC0700-040-RU Page 61 April 15, 2013 MBSC0700-040-RU 5.4.4.2 Using Uplink Pilot Tone Generator Figure 52 Up/Down Link Verification Each RU in the remote node is equipped with an Uplink Pilot Tone Generator which will generate a CW RF tone out of the RU back towards the FIU and BIU.. By measuring the RF power at the RXout port of the BIU the end-to-end uplink system gain can be verified, and band-to-band / node-to-node, variations calibrated without additional test equipment required at the Remote Node. Verify the end-to-end Uplink Gain for each frequency band as follows:
1. Click on the RU for the desired frequency band. The component window ;will pop up as shown in Figure 52 Up/Down Link Verification a. Uplink Pilot Frequency: 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. 1732.5 MHz for AWS band) b. Uplink Pilot Frequency Switch: select ON from the drop-down box c. Click Save to turn the Uplink Pilot generator ON 2. Connect an RF power meter to the corresponding RXout port of the BIU a. A -6 dBm value in the Uplink Pilot Frequency Output Power field of the RU corresponds to an equivalent signal of -60 dBm at the input to the RU MBSC0700-040-RU Page 62 April 15, 2013 MBSC0700-040-RU b. Variations in filtering, amplifiers, and optical loss may cause the actual system gain to vary
+/- 6 dB. All paths can be normalized by adjusting uplink attenuation settings in the BIU. 3. This procedure should be repeated for each frequency band in the system Note: Uplink Pilot Frequency Switch should be off during normal operations. This function is intended for testing, verifying, and adjusting uplink performance and will interfere with normal operation of the system. 5.5 Monitoring and Alarms 5.5.1 Operational Status 5.5.1.1 Host Unit The EMS Local GUI graphical interface will notify users of an error or malfunction in the Host Unit with a red popup alarm indicator. The alarms will also be displayed in the lower section of the component window.

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) MBSC0700-040-RU Page 67 April 15, 2013 MBSC0700-040-RU The mBSC-C Host Unit components are equipped with multiple LED indicators that show status and alarms by displaying Green, Red or Off. Detailed descriptions of the LED indicators are provided respectively in section 3.2.7Host Unit Interface. The NMS software provides detailed alarm information which includes module level faults, circuit faults and measured value faults such as door, RF power and temperature. 6.4 Troubleshooting Quick Guide Use this section to quickly troubleshoot alarms and faults. Table 16 Troubleshooting Quick Guide Problem No RF output RF output power level is low Loss of phone service, but the RF signal level is normal Power supply is out of service Quick Troubleshooting Steps / Possible Cause 1) Optical path is faulty;
2) Downlink path BTS input signal is low/not present 3) Remote Node RU is faulty. Measure the downlink output power at the output of the RU, and at the input to he antenna 1)Passive components between the RU and the antenna port are faulty;
2) Host Unit RF input connections are faulty;
3) Optical path is faulty;
4) RU is faulty. 1) Test calling in the coverage area of original BTS. It may be the BTS problem if the situation is the same;
2) Measure the gain both of the forward path and reserve path to see whether they are close;
3) RU LNA module is faulty. 1) Measure the DC power input source. If the voltage is out of 48VDC +/- 20%, add a regulated power supply between the power in connector and the power source. 2) The interior power unit is faulty.

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. For MIMO operation a duplicate set of BTS interface, fiber transmission, and remote node equipment is required, along with an additional optical fiber. 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.

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 GUIhttp://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. MBSC0700-040-RU Page 43 April 15, 2013 5.1.2 Using USB Port MBSC0700-040-RU 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 URLhttp://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 dBm1dB (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 MBSC0700-040-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. Click on the BIU in the topology diagram and the component window will pops up on the right as shown in Figure 50 - BIU Attenuator. 2.

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 52 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 MBSC0700-040-RU Page 61 April 15, 2013 MBSC0700-040-RU 5.4.4.2 Using Uplink Pilot Tone Generator Figure 52 Up/Down Link Verification Each RU in the remote node is equipped with an Uplink Pilot Tone Generator which will generate a CW RF tone out of the RU back towards the FIU and BIU.. By measuring the RF power at the RXout port of the BIU the end-to-end uplink system gain can be verified, and band-to-band / node-to-node, variations calibrated without additional test equipment required at the Remote Node. Verify the end-to-end Uplink Gain for each frequency band as follows:
1. Click on the RU for the desired frequency band. The component window ;will pop up as shown in Figure 52 Up/Down Link Verification a. Uplink Pilot Frequency: 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. 1732.5 MHz for AWS band) b. Uplink Pilot Frequency Switch: select ON from the drop-down box c. Click Save to turn the Uplink Pilot generator ON 2. Connect an RF power meter to the corresponding RXout port of the BIU a. A -6 dBm value in the Uplink Pilot Frequency Output Power field of the RU corresponds to an equivalent signal of -60 dBm at the input to the RU MBSC0700-040-RU Page 62 April 15, 2013 MBSC0700-040-RU b. Variations in filtering, amplifiers, and optical loss may cause the actual system gain to vary
+/- 6 dB. All paths can be normalized by adjusting uplink attenuation settings in the BIU. 3. This procedure should be repeated for each frequency band in the system Note: Uplink Pilot Frequency Switch should be off during normal operations. This function is intended for testing, verifying, and adjusting uplink performance and will interfere with normal operation of the system. 5.5 Monitoring and Alarms 5.5.1 Operational Status 5.5.1.1 Host Unit The EMS Local GUI graphical interface will notify users of an error or malfunction in the Host Unit with a red popup alarm indicator. The alarms will also be displayed in the lower section of the component window. Figure 53 - Host Unit Alarm Status MBSC0700-040-RU Page 63 April 15, 2013 5.5.1.2 Remote Node MBSC0700-040-RU In the case of a Remote Node malfunction, the affected unit will also be marked with a red popup alarm indicator.

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) MBSC0700-040-RU Page 67 April 15, 2013 MBSC0700-040-RU The mBSC-C Host Unit components are equipped with multiple LED indicators that show status and alarms by displaying Green, Red or Off. Detailed descriptions of the LED indicators are provided respectively in section 3.2.7Host Unit Interface. The NMS software provides detailed alarm information which includes module level faults, circuit faults and measured value faults such as door, RF power and temperature. 6.4 Troubleshooting Quick Guide Use this section to quickly troubleshoot alarms and faults. Table 16 Troubleshooting Quick Guide Problem No RF output RF output power level is low Loss of phone service, but the RF signal level is normal Power supply is out of service Quick Troubleshooting Steps / Possible Cause 1) Optical path is faulty;
2) Downlink path BTS input signal is low/not present 3) Remote Node RU is faulty. Measure the downlink output power at the output of the RU, and at the input to he antenna 1)Passive components between the RU and the antenna port are faulty;
2) Host Unit RF input connections are faulty;
3) Optical path is faulty;
4) RU is faulty. 1) Test calling in the coverage area of original BTS. It may be the BTS problem if the situation is the same;
2) Measure the gain both of the forward path and reserve path to see whether they are close;
3) RU LNA module is faulty. 1) Measure the DC power input source. If the voltage is out of 48VDC +/- 20%, add a regulated power supply between the power in connector and the power source. 2) The interior power unit is faulty.
