Signal failure BER threshold of 10
-3
(1 out of 1,000 bits transmitted is in error). Signal
failure is associated with a “hard” failure. Signal fail is determined when any of the
following conditions are detected: loss of signal (LOS), loss of frame (LOF), line alarm
indication bridge and selector signal (AIS-L), or the BER threshold exceeds the
configured rate.
To specify different BER thresholds, enter the following commands in Enable mode:
Monitoring PoS Ports
