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 seconds
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.

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.
DS3 AISS-P
Alarm Indication Signal Seconds-Path (AISS-P) is a count of seconds
containing one or more AIS defects.
DS3 UAS-P
Unavailable Seconds-Path (UAS-P) is a count of one-second intervals
during which the DS3 path is unavailable.

Parameter Definition
STS CV-P
Near-End STS Path Coding Violations (CV-P) is a count of BIP errors
detected at the STS path layer (i.e., using the B3 byte). Up to eight BIP
errors can be detected per frame; each error increments the current CV-P
second register.
STS ES-P
Near-End STS Path Errored Seconds (ES-P) is a count of the seconds
when at least one STS path BIP error was detected. An AIS-P defect (or a
lower-layer, traffic-related, near-end defect) or an LOP-P defect can also
cause an STS ES-P.
