Parameter
Definition
DS3 CV-L
Code Violation Line (CV-L) indicates the number of coding violations
occurring on the line. This parameter is a count of bipolar violations
(BPVs) and excessive zeros (EXZs) occurring over the accumulation
period.
occurring on the line. This parameter is a count of bipolar violations
(BPVs) and excessive zeros (EXZs) occurring over the accumulation
period.
DS3 ES-L
Errored Seconds Line (ES-L) is a count of the seconds containing one or
more anomalies (BPV + EXZ) and/or defects (loss of signal) on the line.
more anomalies (BPV + EXZ) and/or defects (loss of signal) on the line.
DS3 SES-L
Severely Errored Seconds Line (SES-L) is a count of the seconds
containing more than a particular quantity of anomalies (BPV + EXZ >
44) and/or defects on the line.
containing more than a particular quantity of anomalies (BPV + EXZ >
44) and/or defects on the line.
DS3 LOSS-L
Line Loss of Signal (LOSS-L) is a count of one-second intervals
containing one or more LOS defects.
containing one or more LOS defects.
