5.1.3 RF Interface at BIU
Btu can be connected With Bi-Directional Amplifier and Base Station Tranceiver
To connect Btu With BDA‘ you need to use a duplexer or a circulator to separate TX/RX signals
from each other
Btu can feed external TX/PX Signals from the Back Plane
Using MDBu Separated from each carner band, BIU can easily expand and interface wtth bands
As seen in the table below‘ MDBu is dtthed into Single and Dual Bands The unit can be
connected With two to four carrier signals per band At the rear‘ #1~4 marks are seen in order

Through spectrum, you need to check signals sent from BTs TX. If the signals exceed
input range (-20dBm~+10dBm), you can connect an attenuator ahead ofthe input port
to put the signals in the input range.
BIU interface with Bi-Directional Amplifier
Basically. BIU is in Simplexer type: when you use BDA, you need to separate BDA
signals from TX and RX type.
Using a duplexer or a circulator, you can separate TXIRX signals of an external device
from each other.

- Given the TX input range (-20dBm~+i UdBm/Totai per port)‘ make sure to see ifthe
value IS in the input range. using Spectrum Analyzer, when you connect input ports
5.1.4 MDBU insertion
MDBU is designed to let a MDBU be inserted into any slot.
BIU can be equipped with a total of four MDBUs. If only one MDBU is insened into a
slot with the other slots reserved, you need to insert BLANK cards into the other slots.
If you do not terminate input and output ports of MCDU‘ which combines T>< signals and
diVides RX Signals, it Wl|| cause loss and generation of spurious Signals at the other party's band
Given thifi, make sure to insert MDBU BLANK into slots oiMDBU

compared with RX Output power
5.1.5 ODU Interface
BIU supports up to four ODUs. At the rear of BIU, eight RF input and output ports for
ODU and four power ports for power supply and communication are provided. At BIU,
you can check installation information of ODU.

6.1.2 TX Operation at BIU
TX level to be sentto BIU should be lfl the range ot—QOdBm ~ + lOdBm lfthe level exceeds the
range‘ you need to connect an attenuator Wlth the front end of BIU lnput and adjust the level in
the corresponding range Out of the range. mammal power cannot be outputted and so you
need to increase output power of EDA or adjust attenuation amount of BTS's coupler orATT to
adjust the level
For signals of all bands, you need to check‘ using spectrum if they are in an appropnate level
before making connectlon Wlth input port of BIU and then check ifthere are spurious signals
You need MDBU of a band you want to use Insert the unit into Blu and check lf lt works
normally For MDBU. up to two TX inputs are prowded lnput level per port is -20dBm~+10dBm

6.1.3 RX Operation at BIU
For RX operation at BIU, you need to sel 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 ofa desired gain, you can set it as 50dB-Rx ATT. Use the terminal and check if TX
Adjust value and Ecllo value is appropriate.
To block high signals from entering BTS or BDA, keep ALC mode activated (ON).
6.1.4 Setting whether to use ROUIOEU 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.

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.
Forupper level. ROU can be connected With ODU and OEU It has AGC function for SdBo of
optical cable loss

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 BROU.This is reason why OEU supports up to ZDOU. The DOU
supports up to 4optical port to connect ROU
ROU can work with a DC Feeder and an Optic Cable Feeder. For power supply of OEU,
a power supply in DC-DC type is provided
For upper level, OEU can be connected with ODU. It has AGC function for 5dBn of
optical cable loss. The following show operational procedures after installation of OEU.

7.5 Input power limit function (TX InputALC)
The DAS has TX inpul 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, BSOceIIuIar 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 If input power increase, input ATT is adjusted again to limit increased input
power. Also, if input power decrease input ATT return to initial ATT
7.6 Optic loss compensation
The DAS 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 ofoptical loss, basic TX OPTIC ATT is 12dB: for
5dBo of optical loss, TX OPTIC ATT is 4118. OPTIC COMP Works only onetime 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 competed
2. Over Optic Loss: Generated optical loss exceed 5dBo or more.
St Communication Fail: Communication with ROU is under poor condition.
