6.1.2 TX Operation at BIU
TX level to be sent to BIU should be in the range ot-ZOdBm - + 10dBm. lfthe level exceeds the
range, you need to connect an attenuator with the front end of 3111 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 adiust attenuation amount of BTS's coupler of MT to
adjust the level.
For signals 01 all bands, you need to check, using spectrum, it they are in an appropriate level
before making connection with input port of BIU and then week it there are spurious signals.
You need MDBU at a hand you want to user Insert the unit into BIU and check it it works
normally. For MDBU, up to two TX inputs are provided. Input level per port is -20dBn1~+10dBm,

This chapter describes additive functions of SMDR-NH124.
7.1 Shutdown function (TX output shutdown)
The DAS has an automatic shutdown function to protect the DAS itself and the wireless
network when the normal operational conditions cannot be maintained
The DAS shut down automatically when the composite power downlink output power is
above the values defined as average for the device for a period not to exceed
Sseconds. Criterion level is set through GUI
After automatic shutdown, the DAS may automatically turn-on in order to assess
whetherthe temporary condition has changed. If the condmon is st|ll detected, the DAS
shall shutdown again. These actions will be repeated 5 times
After Stime repetition, if the condition is still detected. the DAS will be shutdown
permanently. The following diagram shows the shutdown logic
3- s-nc m 5.“ g.“
Criterion vdue
After the retry logic exhausts itself, if the DAS still detected a fault status then the DAS
will shutdown permanently and illuminate the fault via visual fault indicator
Permanent shutdowns of the DAS will also be reported to the NOC through the NMS
7.2 Total Power Limit function (I'X Output ALC)
In order to protect HPA and not to radiate spurious emission, output power don't
radiate above defined value which operator set in advance. To execute this function,
operator should turn-on the ALC function and set limit level through GUI. If the output
power exceed above the defined value, output attenuator is adjusted to operate within
defined value. The output attenuators adjustment range is above 25dB. If output power
decease. applied ATT by AGC function return to initial ATT
7.3 Output power automatic setting function (TX Output AGC)
To provide convenience of setting output power at initial setup automatically, operator
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 lunction is normally completed.
2. Not Opterete OPTIC Comp: Optic Comp is not executed.
1 Lack of ATT: There is no attenuation available.
If normal logic don’t executed, changed ATT return to initial ATT
Through output AGC function, can be checked whether optic compensation is executed
or not
7.4 Input power AGC function (I'X Input AGO)
This Iunction is to give convenienoe to operator when setting intial installation
Without spectrum analyzer, we can know input power value through power display
window of GUI. Use TX IN AGC function and automatically set internal ATT depending
on input level. ATT is automatically set based on -20dl3m 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.

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 ct BIU
For example, BSOceIIular 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. It input power increase, input ATT is adjusted again to limit increased input
power. Also, it input power decrease input ATT return to initial ATT
7.6 Optic lose 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 OOMF'" of ROU as "ON." Optical
compensation of ROU can not be made without oommunimtion with such units in
upper level as ODU or OEU. For 1dBo of optical loss, basic TX OPTIC ATT is 12dl3; 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 3 upper unit by
ROU. PD POWER means input level of Photo Diode to be received from a upper unit.
