5.4 OEU Installation OEU is used to expand ROU in Campus Site. OEU is located at a Remote Closet. As it can be equipped with up to two DOUs, you can expand a total of eight ROUs. 5.4.1 OEU Shelf installation OEU is a shelf in around 2U size. Its width is 19” and so this unit should be inserted into a 19” Standard Rack. OEU is in a Remote Closet, providing optical ports of ROU. The following table shows power consumption of OEU: No.
Note that OEU does not operate if the “+” terminal and the “–“ terminal of the -48V power are not inserted into the accurate polarity. 5.4.3 OEU Optic Cabling OEU is connected with upper ODU. With DOU inserted in it, the unit is connected with ROU. As OEU has a shelf with EWDM in it, the unit makes electronic-optical conversion of TX signals from ODU and makes optical-electronic conversion of RX signals. In addition, OEU can be equipped with up to two DOUs.
For optical adaptor, SC/APC type should be used. To prevent the optical access part from being marred with dirt, it should be covered with a cap during move. When devices are connected through optical cables, you need to clear them using alcohocol to remove dirt. 5.4.4 Insert DOU to OEU Into OEU Shelf, up to two DOUs can be inserted. DOU module is in Plug in Play type. When you insert DOU in OEU, insert the unit into the top DOU1 slot first. You can be careful as the number is silk printed at the left.

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.
1900PCS 30dBm-10*LOG(N) 4 AWS-1 30dBm-10*LOG(N) 4 VHF 24dBm-10*LOG(N) 1 UHF 24dBm-10*LOG(N) 1 Check if the level of TX IN POWER is the same as the value measured through spectrum (Within ±3dB). Use TX IN AGC function and automatically set internal ATT depending on input level. ATT is automatically set based on -20dBm of input . The table below shows TX IN ATT depending on TX IN POWER. For manual setting, you can set ATT depending on input according to the table.
Use various upper/lower limits. 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.
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.
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. 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.
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.
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.
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 ODU1DOU1-ROU1. Set it with the ID of a designed 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. 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.
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.
A. Success: The AGS function is normally made. B. Not Opterate OPTIC Comp: Optic Comp is not executed. C. Lack of ATT: There is no attenuation available. Use various upper/lower limits.
6.3 OEU Operation The figure below shows the level of the system link of SMDR-NH124 (BIU-ODU-OEU-ROU). This section describes OEU-related information. OEU receives various signals through optical modules. The optical signals are converted to RF signal and the RF signal also is amplified to moderate signal level. To transmit to ROU, the signal is converted to optical signal 6.3.1 OEU Operation OEU is in shelf enclosure type. OEU is located at a remote closet in a building.
module's LED of the system. The table below shows normal/abnormal cases depending on the status of each module's LED.
ID Setting Use an RS-232 Cable(Direct Cable) for connection with DEBUG port of OEU. Execute GUI (Graphic User Interface). When you connect OEU directly with a Serial port, the screen will show the TREE of a direct line of units connected with OEU. Basic OEU ID is set as ODU1DOU1. Set it with the ID of a designed OEU.
Checking Communication LED of OEU Step1 : checking whether communicate with BIU(ODU) Check if TXD1 and RXD2 LEDs in OEU front LED make communication. Receiving FSK signals from BIU, OEU sends requessted status value to BIU. During reception, RXD1 LED flicks. During tramsmission, on the other hand, TXD1 LED flicks. At this time, you need to check if whether to use a corresponding OEU is checked on (See "whether to use BIU OEU/ROU"). Step2 : Checking whether communicate with ROU OEU do as Hub.
3. Communication Fail: Communication with ROU is in poor conditin. If OEU 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.

set to wanting output level and turn-on the AGC function and then output power is automatically set to defined level. If AGC logic finished, logic operation results show on the result window of GUI. There are three types of results as follows 1. Success: The AGS function is normally completed. 2. Not Opterate OPTIC Comp: Optic Comp is not executed. 3. Lack of ATT: There is no attenuation available.
-10dBm 10dB 7.5 Input power limit function (TX Input ALC) The DAS has TX input ALC function at the BIU to limit level when input power is increased above level by operated input AGC function Normally, there are more than two input port in the MDBU of BIU For example, 850cellular band has two input port to support both VzW and AT&T Two input power may be different each other. The DAS have input attenuator in first stage of MDBU. Through input AGC function, input ATT is adjusted according to input power.
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 competed 2. Over Optic Loss: Generated optical loss exceed 5dBo or more. 3. Communication Fail: Communication with ROU is under poor condition.
