Ceasing The cause of the alarm has ceased.
40 Battery
fault
RCU,
FON
charger
Error The backup battery on the RCU or the FON PCBA
does not work properly. Suggested remedy: Check
cables or replace battery.
Ceasing The cause of the alarm has ceased.
41 RF block-
ing
Chan-
nel #,
UL/DL
Error Constant carrier, PA off. Uplink carrier has been con-
stantly above 27dBm more than 10 seconds.
Ceasing The cause of the alarm has not been detected for 10
seconds.
42 Antenna
isolation
BSA #,
Chan-
nel #,
UL/DL
Warning Low antenna isolation. The antenna isolation is lower
than the gain set. Gain is reduced by 10dB – 13dB
below the oscillation point. Suggested remedy:
Decrease gain or increase antenna isolation.
Error Low antenna isolation at lowest gain. The gain has
been reduced as much as possible but the oscillation
still remains. The amplifier is turned off. Suggested
remedy: Decrease gain or increase antenna isolation.
Ceasing Normal operation again, that is no oscillation can be
detected 13dB above the gain set.
44 Low sta-
bility mar-
gin
Chan-
nel #,
UL/DL
Warning MRX has detected that antenna isolation is below the
gain set. The gain is reduced 10– 13dB below oscilla-
tion point. Suggested remedy: Decrease the gain or
increase the antenna isolation.
Ceasing The cause of the alarm has ceased.
48 Battery
backup
fault
Exter-
nal
Error If a battery backup unit alarm is connected to external
alarm 2, then the operator can configure the repeater
to display this alarm when the battery backup unit
indicates alarm.
Ceasing The cause of the alarm has ceased.
50 Fiberopti-
cal error
FOT
fiber
optics
Config-
urable
If a fiber unit alarm is connected to external alarm 3,
then the operator can configure the repeater to dis-
play this alarm when the fiber optical unit indicates
alarm.
Ceasing The cause of the alarm has ceased.
55 R2R
Queue full
CU None R2R transmit queue is full, messages are lost. Sug-
gested remedy: Check configuration and cables.
56 R2R Node
lost
CU None An R2R node is lost. Suggested remedy: Check if
node is still connected and operating.
Warning An R2R node is lost. Suggested remedy: Check if
node is still connected and operating.
57 R2R HW
Error
RIA Error R2R HW failure because the CU cannot read the
MAC-ID of the RIA PCBA or any other HW error in
the R2R logic.
Suggested remedy: Replace the RIA PCBA.
