Parameter Definition
CV-S Section Coding Violation (CV-S) is a count of BIP errors detected at the
section-layer (i.e. using the B1 byte in the incoming SONET signa l). Up
to eight section BIP errors can be detected per STS-N frame, with each
error incrementing the current CV-S second register.
ES-S Section Errored Seconds (ES-S) is a count of the number of seconds when
at least one section-layer BIP error was detected or an SEF or LOS defect
was present.
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 can be situations when the SEFS-S parameter is only
incremented based on the presence of th e SE F def e ct .
