SES-S Section Severely Errored Seconds (SES-S) is a count of the seconds when
K (see GR-253 for value) or more section-layer BIP errors were detected
or an SEF or LOS defect was present.
SEFS-S Section Severely Errored Framing Seconds (SEFS-S) is a count of the
seconds when an SEF defect was present. An SEF defect is expected to b e
present during most seconds when an LOS or LOF defect is present.
However, there may be situations when the SEFS-S parameter is only
incremented based on the presence of an SEF defe ct.

Parameter Definition
CV-L Near-End Line Code Violation (CV-L) is a count of BIP errors detected at
the line-layer (i.e. using the B2 bytes in the incoming SONET signal). Up
to 8 x N BIP errors can be detected per STS-N frame; each error
increments the current CV-L second register.
ES-L Near-End Line Errored Seconds (ES-L) is a count of the seconds when at
least one line-layer BIP error was detected or an AIS-L defect was
present.
SES-L Near-End Line Severely Errored Seconds (SES-L) is a count of the
seconds when K (see GR-253 for values) or more l ine -la yer BIP er ror s
were detected or an AIS-L defect was present.
UAS-L Near-End Line Unavailable Seconds (UAS-L) is a count of the seconds
when the line is unavailable. A line becomes unavailable when ten
consecutive seconds occur that qualify as SES-Ls, and it continues to be
unavailable until ten consecutive seconds occur that do not qualify as
SES-Ls.
FC-L Near-End Line Failure Count (FC-L) is a count of the number of near -e nd
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 ev ent
ends when the failure is cleared. A failure event that begins in one period
and ends in another period is counted only in the p er iod wher e it begi n s.
Table8-37 Near-End SONET Path H-byte PMs for the OC-12, OC-48, and OC-192 Cards
Parameter Definition
PPJC-Pdet Positive Pointer Justification Count, STS Path Detected (PPJC-Pdet) is a
count of the positive pointer justifications detected on a particular path on
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 on
an incoming SONET signal.
