Operation

6.1 BIU Operation

6.2 ROU Operation

Confidential & Proprietary 112/139

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.

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 114/139

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.

Confidential & Proprietary 115/139

Depneding on whether to use a port, output varies. Thus, make sure to turn OFF unused

ports.

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

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.

Configuration of BIU-ODU-ROU

Confidential & Proprietary 118/139

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.

Confidential & Proprietary 119/139

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.

Confidential & Proprietary 120/139

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. 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

Confidential & Proprietary 121/139

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.

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

Confidential & Proprietary 122/139

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.

RDU

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").

Confidential & Proprietary 123/139

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

Confidential & Proprietary 124/139

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. 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.

Confidential & Proprietary 125/139

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 126/139

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 127/139

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.

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

Confidential & Proprietary 128/139

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. 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.
