Parameter Definition
CV-S CV-S is a count of B IP errors detected at the section-layer (i.e. using the
B1 byte in the incoming SONET signal). Up to eight section B IP errors
can be detected per STS-N frame; each error increments the current CV-S
second register.
ES-S
ES-S is a count of the number of seconds when at least one section-layer
B IP error was detected or a Severely Errored Frame (SEF) or Loss of
Signal (LOS) defect was present.
SES-S
SES-S is a count of the seconds when K (see GR-253 for value) or more
section-layer B IP errors were detected or a Severely Errored Frame (SEF)
or Loss of Signal (LOS) defect was present.
SEFS-S SEFS-S is a count of the seconds when a Severely Errored Frame (SEF)
defect was present. An SEF defect is expected to be present during most
seconds when a Loss of Signal (LOS) or Loss of Frame (LOF) defect is
present. However, there may be situations when the SEFS-S parameter is
only incremented based on the presence of an SEF defect.
