126 Equipment installation and configuration
To configure the carrier alarm thresholds. Defaults threshold values
are set in the factory and should not be changed unless there is a good
reason for doing so:
Note:
longer than 10 seconds to allow fast recovery of a faulty carrier when
the bit error rate improves. For example, if the duration is set to one
hour, a faulty carrier that starts operating correctly will wait one 1 hour
before the alarm condition is cleared and the carrier becomes available
for traffic again.
Parameter values explanation:
Equipped carrier 1 (Yes or No) Y
Equipped carrier 2 (Yes or No) Y
Enable #2 for Spare (Yes or No) Y
Enable self clearing Alarms

Alarm 0 – No alarm, the carrier is operating without bit errors and without
excessive out of frame. If carrier was previously spared it is automatically
unspared.
Alarm 1 – The alarm indicates a low bit error rate (BER maintenance
threshold). The transmission continues without trying to spare this link.
Carrier maintenance should be scheduled. The alarm LED comes ON.
