Alarm 2 – Bit error rate is high and the carrier is automatically spared if
the spare carrier is available (BER No New Data Calls). Otherwise, the
carrier continues to operate normally for voice calls but no new data calls
are allowed on this carrier.
Alarm 3 – Very high bit error rate (OOS: BER, LOF, LOS, Blue Alarm,
Excessive Frame Slip). If the spare carrier is available, this faulty carrier
will be spared. Otherwise, the carrier is placed out of service and all calls
on this carrier are disconnected.
Alarm Threshold – Number of bipolar violation. E-6 represents 10
error in 1 million bits, E-5 represents 10
E-4 represents 10
Threshold duration – Carrier signal monitoring duration (1 second to
3600 seconds) to detect bipolar violation errors. The error counter is
updated every second for the length of the threshold duration.
Frame Slip Threshold – Number of controlled carrier frame slips allowed
in a given time duration. Preferred threshold is 255.
Frame Slip Threshold duration – Carrier frame synchronization
monitoring duration (1 hour to 24 hours) to detect the number of frame
slips specified by the Frame Slip Threshold. Preferred duration is 1 hour.
The fewer the bipolar violations and/or frame slips, the better the carrier
link performance. Based on the frequency of errors and frame slips, the
specified thresholds determine the occurrence of Alarm 1, Alarm 2, and
Alarm 3.
Alarm Disable command
If the Maintenance LED comes ON and stays ON, a possible cause can be
that the Alarm Disable (A D) command has been executed, which causes
this condition.
