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 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 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 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.
