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 signal). 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 be
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 the SEF defect.
