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.

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
90/99
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
91/99
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
92/99
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
93/99
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
94/99
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

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. 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
96/99
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
97/99
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:

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.
