Confidential & Proprietary 86/99 This chapter describes operation of SMDR-NH124. It deals with procedures and operations for normal system operation after installation. It also describes operations per unit and interworking methods. 6.1 BIU Operation 6.1.1 BIU 6.1.2 TX Operation at BIU TX level to be sent to BIU should be in the range of -20dBm ~ + 10dBm. If the level exceeds the range, you need to connect an attenuator with the front end of BIU input and adjust the level in the corresponding range. Out of the range, maximal power cannot be outputted and so you need to increase output power of BDA or adjust attenuation amount of BTS's coupler or ATT to adjust the level. For signals of all bands, you need to check, using spectrum, if they are in an appropriate level before making connection with input port of BIU and then check if there are spurious signals. You need MDBU of a band you want to use. Insert the unit into BIU and check if it works normally. For MDBU, up to two TX inputs are provided. Input level per port is -20dBm~+10dBm. The following describe settings for 800MHz Public safety MDBU.
Confidential & Proprietary 87/99 Checking the status of the system's LED Indicator After turning on the switch of the power supply in BIU, check information on each module's LED of the system. The table below shows normal/abnormal cases depending on the status of each module's LED. LED information Unit LED Indicates ON Green: MDBU is normally power-supplied. Green: MDBU is normal.MDBUALM Red: MDBU is abnormal; check the alarm through RS-232C.ON Green: MCPU is normally power-supplied.TXD Green flicker: TX signals are transmitted to communicate with ROU. RXD Green flicker: RX signals are received from ROU.

Green: DC output is normal.MPSUALMRed: DC output is abnormal.MDBU Setting Insert MDBU into BIU. Check if the “ON” LED Indicator at the front panel of MDBU is lit green. Make connection with DEBUG port of MCPU through RS-232 Cable (Direct Cable). Check if the ID of MDBU module is searched for in those 1~4 slots of MDBU through GUI. When you select the tab of a corresponding slot (MDBU 1~4) from the main window, you can inquire and set the status of a corresponding MDBU module.
Confidential & Proprietary 88/99 Check if MDBU is inserted into a corresponding slot of BIU. The ID screen shows the following: A. MDBU ID: 800Public Safety, 800PS+900I+Paging, 850C, 700PS+850C, AWS-1,1900P B. Not Insert: This status value appears when MDBU has not been set. C. Link Fail: This status value appears when MDBU has been set but it fails to communicate with modules. Use the ON/OFF (Activation/de-activation) function for a port you want to use and turn it ON. Depneding on whether to use a port, output varies. Thus, make sure to turn OFF unused ports. In the case of VHF+UHF, it contain to MCDU. The table below shows output power depneding on whether to use a port: MDBU Band Output level (Composite power)No. of Max port (N) 700PS 23dBm-10*LOG(N) 2 800PS 23dBm-10*LOG(N) 2 850Cellular 23dBm-10*LOG(N) 2 900I+Paging 23dBm-10*LOG(N) 2 1900PCS 26dBm-10*LOG(N) 4

The following table shows recommended limit settings: Item Recommended Limit Remark TX IN HIGH ALM 15dBm Alarm TX IN LOW ALM -25dBm Alarm RX OUT ALC 0dBm Auto Level control RX OUT HIGH ALM 5dBm Alarm As such, when you finish setting normal input levels and alarm limits, check if the value of MODULE FAILUER LED Indicator is lit green (Normal case). 6.1.3 RX Operation at BIU For RX operation at BIU, you need to set RX gain to prevent BTS or BDA from being affected. There is an ATT setting window to let you adjust gain per band and port. Total RX gain is 50dB. To adjust a desired gain, you need to do the following. For RX gain of a desired gain, you can set it as 50dB-RX ATT. Use the terminal and check if TX Adjust value and Ec/Io value is appropriate. To block high signals from entering BTS or BDA, keep ALC mode activated (ON). 6.1.4 Setting whether to use ROU/OEU at BIU BIU controls overall system, working as common part in any equipment. Connect BIU with such units as ODU, OEU and ROU to be interfaced with the BIU and manually set whether to use the units at the INSTALL window of BIU. To inquire and set information on units in lower level (OEU and ROU) at BIU, you need to check on a corresponding item at INSTALL Menu for a unit to be actually used. This
Confidential & Proprietary 91/99 setting makes BIU actually try to communicate with lower units while collecting the status value of units. The menu below shows INSTALL menu, where you can see topology for overall units at a glance. Overall topology for SMDR-NH124 Configuration of BIU-ODU-ROU Configuration on whether to use BIU varies depending on the topology above and so you need to check on a unit to be installed. Ex.) How to set INSTALL menu when ROU is connected with DOU1 of ODU1, which is connected with BIU:
Confidential & Proprietary 92/99 1. Select INSTALL from GUI menu. 2. Check on ODU1 menu>DOU1>ROU1. 3. Close the INSTALL menu. 4. Check if ROU is created, which was checked on at the left TREE panel. 6.1.5 ODU Operation at BIU BIU can be equipped with up to four ODUs. One ODU can hold two DOUs in it. For information on insertion/deletion of DOU in ODU, you can see at the main window of BIU.
Confidential & Proprietary 93/99 When you select ODU screen from the left TREE panel, you can see DOU1 or DOU2 menu actiavted depending on whether DOU has been inserted. Then, the optical port set at the INSTALL menu is also actiavted to let you check PD value of the optical port. Any optical port not set at the INSTALL menu is seen de-activated in grey. The level of Laser diode received from ROU/OEU is +7dBm·0.5dB. The level of Photo diode will be displayed with losses related to the length of optical cables and insertion loss of optical connecters.
Confidential & Proprietary 94/99 In general, the level of optical PD POWER should be +6dBm~ +2dBm·1.5dB.What is more, ODU has the function of automatically compensating for optical cables. The following procedure is related to how to make optical compensation with ROU connected with port, at a corresponding DOU window of ODU: 1. Check if ODU is smoothly communicating with a corresponding ROU. 2. Select ODU or DOU from the left Tree panel. 3. Set “RX OPTIC COMP” of the optical port of a corresponding DOU as "ON." 4. During optical compensation , the Result window shows "Processing" and then a result value. There are three types of results as follows: A. Success: The optical compensation is normally made. B. Over Optic Loss: Generated optical loss is 5dBo or more. C. Communication Fail: Communication with ROU is in poor conditin. 5. ATT of optical compensation can work based on the numerical expression of 12-2*(LD POWER-PD POWER). 6. Optical compensation can be made not only in ODU but also in ROU.6.2 ROU Operation The figure below shows the level of the system link of SMDR-NH124 (BIU-ODU-ROU). This section describes ROU-related information. ROU receives various signals through optical modules. The signals are filtered only for corresponding signal band from a corresponding RDU module and amplified with a High Power Amplifier. Then, the multiplexer combines the signals with others and sends them with an antenna. 6.2.1 ROU Operation ROU is in one-body enclosure type. ROU is located at a remote closet in a building.
Confidential & Proprietary 95/99 And it can be installed on a wall or into a rack. Basically, one antenna is provided. To install a variety of antennas, you need such devices as a divider and a coupler. ROU can work with a DC Feeder and an Optic Cable Feeder. For power supply of ROU, a power supply in AC-DC and DC-DC type is provided to let you select a power supply suitable for an application. For upper level, ROU can be connected with ODU and OEU. It has AGC function for 5dBo of optical cable loss. The following show operational procedures after installation of ROU. Checking the status of ROU's LED Indicator After turning on the switch of the power supply in ROU, check information on each module's LED of the system. The table below shows normal/abnormal cases depending on the status of each module's LED. Unit LED Indicates ON Green: ROU is normally power-supplied.Green: Laser Diode is normal.LDRed: Laser Diode is abnormal. Green: Photo Diode is normal.PDRed: Photo Diode is abnormal; check optical cables. TXDGreen flicker: TX signals are transmitted to communicate with BIU/OEU.RXD Green flicker: RX signals are received from BIU/OEU. Green: ROU system is normal. RCPU ALMRed: ROU system is abnormal; check the alarm through RS-232C. The power is not supplied. RDU ON The power is supplied.
Confidential & Proprietary 96/99 Normal Operation ALM Abnormal Operation The power is not supplied or the polarity of -48V is reversed. RPSU ON The power is supplied. ID Setting Use an RS-232 Cable(Direct Cable) for connection with DEBUG port of ROU RCPU. Execute GUI (Graphic User Interface). When you connect ROU directly with a Serial port, the screen will show the TREE of a direct line of units connected with ROU. Basic ROU ID is set as ODU1-DOU1-ROU1. Set it with the ID of a designed ROU. Before setting an ROU ID, you need to check if ROU is connected with the optical port of ODU or OEU (See System Topology at "Setting whether to use BIU"). If multiple ROUs connected to BIU share the same ID, the screen will fail to read status information on the ROUs with the same IDs. Therefore, make sure not to redundantly set ROU ID.Checking Communication LED of RCPU Check if TXD and RXD LEDs in RCPU make communication. Receiving FSK signals from BIU, ROU sends requessted status value to BIU. During reception, RXD LED flicks. During tramsmission, on the other hand, TXD LED flicks. At this time, you need to check if whether to use a corresponding ROU is checked on (See "whether to use BIU OEU/ROU").
Confidential & Proprietary 97/99 ROU Optic Comp Operation ROU has the function of automatically compensating for optical loss. It can do the work for up to 5dBo of optical loss. Set “TX OPTIC COMP” of ROU as "ON." Optical compensation of ROU can not be made without communication with such units in upper level as ODU or OEU. For 1dBo of optical loss, basic TX OPTIC ATT is 12dB; for 5dBo of optical loss, TX OPTIC ATT is 4dB. OPTIC COMP works only one time before it stays dormant. The figure below shows a screen for OPTIC Information in ROU GUI. LD POWER means output level of ROU Laser Diode, which is sent to a upper unit by ROU. PD POWER means input level of Photo Diode to be received from a upper unit. During optical compensation, the Result window shows "Processing" and then a result value. There are three types of results as follows: 1. Success: The optical compensation is normally made. 2. Over Optic Loss: Generated optical loss is 5dBo or more. 3. Communication Fail: Communication with ROU is in poor conditin. If ROU does not make optical compensation, there will be erors in the budget of system link. It can cause lower output level or make Spurious Emission not satisfying for a standard. RDU Setting Insert an RDU+BPF assembly you want to offer service with it and then connect the Multiplexer with interface cable (See Sector 5: How to install RDU at the INSTALL part).
Confidential & Proprietary 98/99 Through GUI, check if the ID of RDU module is inquired at LEFT, MIDDLE and RIGHT slots of RDU. When you select the tab of a corresponding slot (LEFT, MIDDLE and RIGHT) from the main window of ROU, you can inquire and set the status of a corresponding RDU module. Set HPA of a corresponding RDU as “ON.” Use TX OUTPUT AGS function and set it as a desired output level. The table below shows maximally available Composit Powerlevels that can be set per band: RDU Band Power that can be maximally set Setting range 700PS 23dBm 0 ~ 23dBm 800PS 23dBm 0 ~ 23dBm 850Cellular 23dBm 0 ~ 23dBm 900I+Paging 23dBm 0 ~ 23dBm 1900PCS 26dBm 0 ~ 26dBm AWS-1 26dBm 0 ~ 26dBm VHF 24dBm 0~24dBm UHF 24dBm 0~24dBm AGS function enables you to adjust output power as you like. While the AGS function is being executed, the Result window shows "Processing" and then a result value. There are three types of results as follows: A. Success: The AGS function is normally made.
Confidential & Proprietary 99/99 B. Not Opterate OPTIC Comp: Optic Comp is not executed. C. Lack of ATT: There is no attenuation available. Use various upper/lower limits. The following table shows recommended limit settings: Item Recommended Limit Remark TX OUTPUT HIGH ALM Max Composit Power+1dB Alarm TX OUTPUT LOW ALM 0dBm Alarm TX OUTPUT ALC Max Composit Power Auto Level control TX OUTPUT SD Max Composit Power+2dB Shutdown RX ALC -45dBm If TX OUTPUT HIGH ALM is higher than a setting value, alarms will be genrated. If TX OUTPUT LOW ALM is lower than a setting value, alarms will be genrated. TX OUTPUT HIGH ALM/LOW ALM tends to work only as warning. When you activate (“ON”) TX OUTPUT ALC, outputs will be restricted depending on a setting output value. When you activate (“ON”) TX OUTPUT SD, output will be turned OFF once output power level reaches the same as SD setting value. Upon SD operation, check output level after 10 minutes and then check the status again. When you activate (“ON”) RX ALC, inputs will be restricted depending on a setting value. As described above, when normal output level and alarm limit values are set, you need to check if the value of MODULE FAILUER LED Indicator is normally seen green. For unused bands, you need to use band turning-ON/-OFF function to turn them off. Once a RDU band is turned off, its status value will not be used in case of alarms.
