Definition
Code Violation Line (CV-L) is a count of B IP errors detected at the
line-layer (i.e. using the B2 bytes in the incoming SONET signal). Up to
8 x N B IP errors can be detected per STS-N frame; each error increments
the current CV-L second register.
Errored Seconds Line (ES-L) is a count of the seconds when at least one
line-layer B IP error was detected or an AIS-L defect was present.
Severely Errored Seconds Line (SES-L) is a count of the seconds when K
(see GR-253 for values) or more line-layer B IP errors were detected or
an AIS-L defect was present.
UAS-L is a count of the seconds when the line is unavailable. A line
becomes unavailable at the onset of ten consecutive seconds that qualify
as Severely Errored Seconds Line (SES-Ls), and continues to be
unavailable until the onset of ten consecutive seconds that do not qualify
as SES-Ls.
FC-L is a count of the number of near-end line failure events. A failure
event begins when an AIS-L failure or a lower-layer traffic-related,
near-end failure is declared. This failure event ends when the failure is
cleared. A failure event that begins in one period and ends in another
period is counted only in the period where it begins.

On CTC, the count fields for Positive Point Justification Count (PPJC) and Negative Pointer
Justification Count (NPJC) PMs appear white and blank unless they are enabled on the
Provisioning > Line tabs. See
Positive Pointer Justification Count path-detected (PPJC-Pdet) is a count
of the positive pointer justifications detected on a particular path on an
incoming SONET signal.
Negative Pointer Justification Count path-detected (NPJC-Pdet) is a count
of the negative pointer justifications detected on a particular path on an
incoming SONET signal.
Positive Pointer Justification Count path-generated (PPJC-Pgen) is a
count of the positive pointer justifications generated for a particular path
to reconcile the frequency of the SPE with the local clock.
Negative Pointer Justification Count path-generated (NPJC-Pgen) is a
count of the negative pointer justifications generated for a particular path
to reconcile the frequency of the SPE with the local clock.
