Table 8-16 Near-End DS3 Line PMs for the DS3-12E and DS3N-12E 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 (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.
DS3 LOSS-L
Line Loss of Signal (LOSS-L) is a count of one-second intervals
containing one or more LOS defects.
Table 8-17 Near-End DS3 Path PMs for the DS3-12E and DS3N-12E Cards
Parameter Definition
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.
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.
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.
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.
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.
Table 8-18 Near-End CP-bit Path PMs for the DS3-12E and DS3N-12E Cards
Parameter Definition
DS3 CVCP-P
Code Violation Path (CVCP-P) is a count of CP-bit parity errors occurring
in the accumulation period.
DS3 ESCP-P
Errored Second Path (ESCP-P) is a count of seconds containing one or
more CP-bit parity errors, one or more SEF defects, or one or more AIS
defects. ESCP-P is defined for the C-bit parity application.
