Table 8-7 Near-End SONET Path PMs for the EC1 Card
Parameter Definition
Note SONET path PMs will not count unless IPPM is enabled. For additional information, see
Enabling Intermediate-Path Performance Monitoring, page 8-10. The far-end IPPM feature is
not supported in Software R3.0, R3.1, or R3.2. However, SONET path PMs can be monitored
by logging into the far-end node directly.
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. STS ES-P can also be
caused by an AIS-P defect (or a lower-layer, traffic-related, near-end
defect) or an LOP-P defect.
STS FC-P
Near-End STS Path Failure Counts (FC-P) is a count of the number of
near-end STS path failure events. A failure event begins when an AIS-P
failure, an LOP-P failure, a unequipped path (UNEQ-P) or a trace
identifier mismatch (TIM-P) failure is declared. A failure event also
begins if the STS PTE monitoring the path supports ERDI-P for that path.
The failure event ends when these failures are cleared.
STS SES-P
Near-End STS Path Severely Errored Seconds (SES-P) is a count of the
seconds when K (2400) or more STS path BIP errors were detected. STS
SES-P can also be caused by an AIS-P defect (or a lower-layer,
traffic-related, near-end defect) or an LOP-P defect.
STS UAS-P
Near-End STS Path Unavailable Seconds (UAS-P) is a count of the
seconds when the STS path was unavailable. An STS path becomes
unavailable when ten consecutive seconds occur that qualify as SES-Ps,
and it continues to be unavailable until ten consecutive seconds occur that
do not qualify as SES-Ps.

Parameter Definition
Note On CTC, the count fields for PPJC and NPJC PMs appear white and blank unless they are
enabled on the Provisioning > Line tabs. For procedures, see Enable Pointer Justification Count
Performance Monitoring, page 8-13.
PPJC-Pdet
Positive Pointer Justification Count, STS Path Detected (PPJC-Pdet) is a
count of the positive pointer justifications detected on a particular path in
an incoming SONET signal.
NPJC-Pdet
Negative Pointer Justification Count, STS Path Detected (NPJC-Pdet) is
a count of the negative pointer justifications detected on a particular path
in an incoming SONET signal.
