Table8-13 Near-End DS3 Line PMs for the DS3 and DS3N Cards
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.
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.
DS3 SES-L Severely Errored Seconds Line (SES-L) is a count of the second s
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.
Table8-14 Near-End DS3 Path PMs for the DS3 and DS3N Cards
Parameter Definition
DS3 ES-P Errored Seconds-Path (ES-P) is a count of one-second intervals
containing one or more CRC-6 errors, or one or more CS events, or one
or more SEF or AIS defects.
DS3 SES-P Severely Errored Seconds-Path (SES-P) is a count of seconds where 320
or more CRC-6 errors occur or one or more SEF or AIS defects occur.
DS3 SAS-P Severely Errored Frame/Alarm Indication Signal-Path (SAS-P) is a count
of seconds containing one or more SEFs or one or more AIS defects.
