Section6 Operation 6.1 BIU Operation 6.
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.
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 ON MDBU Indicates Green: MDBU is normally power-supplied. Green: MDBU is normal. ALM Red: MDBU is abnormal; check the alarm through RS-232C. MCPU ON Green: MCPU is normally power-supplied.
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. The table below shows output power depneding on whether to use a port: MDBU Band Output level (Composite No.
-20dBm 0dB -9dBm 11dB +1dBm 21dB -19dBm 1dB -8dBm 12dB +2dBm 22dB -18dBm 2dB -7dBm 13dB +3dBm 23dB -17dBm 3dB -6dBm 14dB +4dBm 24dB -16dBm 4dB -5dBm 15dB +5dBm 25dB -15dBm 5dB -4dBm 16dB +6dBm 26dB -14dBm 6dB -3dBm 17dB +7dBm 27dB -13dBm 7dB -2dBm 18dB +8dBm 28dB -12dBm 8dB -1dBm 19dB +9dBm 29dB -11dBm 9dB 0dBm 20dB +10dBm 30dB -10dBm 10dB Edit Naming of a port and set it as a desired character string (up to 12 characters).
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.
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: 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. 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.
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. 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.
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.
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 ON Indicates Green: ROU is normally power-supplied. Green: Laser Diode is normal. LD Red: Laser Diode is abnormal. Green: Photo Diode is normal. PD Red: Photo Diode is abnormal; check optical cables. RCPU Green flicker: TX signals are transmitted to communicate with TXD BIU/OEU.
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.
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"). 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.
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).
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.
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.
6.3.1 OEU Operation OEU is in shelf enclosure type. OEU is located at a remote closet in a building. And it can be installed into a rack. OEU is for role as hub. It is to expand toward campus cluster, it is only one optical cable to expand 8ROU.This is reason why OEU supports up to 2DOU. The DOU supports up to 4optical port to connect ROU Basically, one antenna is provided. To install a variety of antennas, you need such devices as a divider and a coupler.
Unit LED ON Indicates Green: ROU is normally power-supplied. Green: Laser Diode is normal. LD Red: Laser Diode is abnormal. Green: Photo Diode is normal. PD Red: Photo Diode is abnormal; check optical cables. RCPU Green flicker: TX signals are transmitted to communicate with TXD BIU/OEU. RXD Green flicker: RX signals are received from BIU/OEU. Green: ROU system is normal. ALM Red: ROU system is abnormal; check the alarm through RS-232C. ON The power is not supplied. The power is supplied.
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.
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.
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). Through GUI, check if the ID of RDU module is inquired at LEFT, MIDDLE and RIGHT slots of RDU.
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.
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.
