15.4.3 DS3i-N-12 Card Performance Monitoring Parameters
The PM parameters for the DS3i-N-12 card are described in Table 15-9 through Table 15-14 on
page 15-13.
Table 15-9 Line PM Parameters for the Near-End DS3i-N-12 Card
Parameter Definition
DS3 CV-L Code Violation Line (CV-L) indicates that the number of coding
violations occurring on the line. This parameter is a count of BPVs and
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 (for example, LOS) 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 15-10 C-Bit and M23 Framing Path PM Parameters for the Near-End DS3i-N-12 Card
Parameter Definition
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 severely errored framing (SEF) defects, or
one or more AIS defects.
DS3 SESP-P Severely Errored Seconds Path (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 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 UASP-P Unavailable Second Path (UASP-P) is a count of one-second intervals
when the DS-3 path is unavailable. A DS3 path becomes unavailable when
ten consecutive SESP-Ps occur. The ten SESP-Ps are included in
unavailable time. After the DS-3 path becomes unavailable, it becomes
available when ten consecutive seconds with no SESP-Ps occur. The ten
seconds with no SESP-Ps are excluded from unavailable time.
DS3 AISS-P AIS Seconds Path (AISS-P) is a count of one-second intervals containing
one or more AIS defects.
