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 (i.e. loss of signal) on the
line.
more anomalies (BPV + EXZ) and/or defects (i.e. 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.

DS3 AISS-P
AIS Seconds Path (AISS-P) is a count of one-second intervals containing
one or more AIS defects.

DS3 CVP-P
Code Violation Path (CVP-P) is a code violation parameter for M23
applications. CVP-P is a count of P-bit parity errors occurring in the
accumulation period.
applications. CVP-P is a count of P-bit parity errors occurring in the
accumulation period.
DS3 ESP-P
Errored Second Path (ESP-P) is a count of seconds containing one or more
P-bit parity errors, one or more SEF defects, or one or more AIS defects.
P-bit parity errors, one or more SEF defects, or one or more AIS defects.
DS3 SASP-P
SEF/AIS Seconds Path (SASP-P) is a count of one-second intervals
containing one or more SEFs or one or more AIS defects on the path.
containing one or more SEFs or one or more AIS defects on the path.
DS3 SESP-P
Severely Errored Seconds Path (DS3 SESP-P) is a count of seconds
containing more than 44 P-bit parity violations, one or more SEF defects,
or one or more AIS defects.
containing more than 44 P-bit parity violations, one or more SEF defects,
or one or more AIS defects.
DS3 UASP-P
Unavailable Second Path (DS3 UASP-P) is a count of one-second
intervals when the DS3 path is unavailable. A DS3 path becomes
unavailable when ten consecutive SESP-Ps occur. The ten SESP-Ps are
included in unavailable time. Once unavailable, the DS3 path becomes
available when ten consecutive seconds with no SESP-Ps occur. The ten
seconds with no SESP-Ps are excluded from unavailable time.
