SONET far end has detected an AIS-L condition.

Far end has detected an AIS-P condition.

The reference source for the secondary clock has failed.

DSX Severely errored frame seconds threshold crossing alert.

Severely errored frame seconds threshold crossing alert for section layer.

Severely errored seconds threshold crossing alert for line layer at far end.

Check source (external, optical in, or other AIC card) for alarms and correct as necessary.

The incoming signal frame has an error rate of 1.6E-5 or worse for a period of time less than ten seconds. An SES can also be caused by a physical failure such as LOS for less than ten seconds. Examine the physical circuit to determine if there are any impairments.
