5.2 LED Indications
The Pisces Digital ICS Repeater is designed with built-in LED indicators to simplify the installation process.
Details indications can be found below. In general, the more green LEDs the better when it comes to the two
sets of LEDs for RSSI and Isolation.

Indication
POWER
On Calls are being made through the repeater.
Blinking
3 seconds after no calls are being made, repeater would go into
sleep mode.
ALARM
On
Overpower; Over temperature; Isolation; Unit faulty.
Alarm could be caused by any one of the conditions above.
Please check with OMT for exact cause of alarm.
Off
Normal
.
RSSI
0 on
<-95dBm – basically no signal detected. External donor
recommended.
1 on
-94~-89dBm – signal is weak. Although repeater can work,
service
area may be limited du
e to weak input signal.
2 on
-
88~
-
83dBm
–
signal is
sufficient. Service area still limited.
3 on
-82~-77dBm – recommended minimum input is -80dBm.
Therefore with 3 LED on, the repeater is functioning well.
4 on
-76~-71dBm – signal is good. Coverage area can be around
250m
2
with this input signal.
5 on
>-70dBm – signal is strong. PS has can perform well under most
conditions with 5 LEDs on. However, to achieve maximum output
power of 10dBm, input should be at -60dBm. This value can be
checked with OM
T. See section 7.5 for OMT monitor information.
Only
need to
check then Isolation LED when external donor or service antenna is in use.
ISOLATION
0 on
<39dB – donor and service are too close. Isolation alarm would
be triggered when isolation value reach
es 35dB.
1 on
40~44dB
Isolation not ideal. Whenever isolation is below 60dB,
AGA would reduce according to isolation value to
avoid oscillation. For maximum gain, ensure that all 5
isolation LED are on.
2 on
45~49dB
3 on
50~54dB
4 on
55~59dB
5 on
>60dB
–
isolation is good. PS can perform with maximum gain.
* UL Stand-By Mode would be activated when UL signal is <-90dBm for over 3 seconds. 90dBm). UL Stand-By
Mode deactivates when UL signal is >-85dBm. When UL Stand-By Mode is activated, green power LED will
be blinking until UL transmission resumes.
