CV-S

Section Coding Violation (CV-S) is a count of BIP errors detected at the section-layer (that is, using the B1 byte in the incoming SONET signal). Up to eight section BIP errors can be detected per STS-N frame; each error increments 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 loss of signal (LOS) defect was present.

An SEF defect is expected during most seconds where an LOS or loss of frame (LOF) defect is present.

PSC (BLSR)

For a protect line in a two-fiber ring, Protection Switching Count (PSC) refers to the number of times a protection switch has occurred either to a particular span's line protection or away from a particular span's line protection. Therefore, if a protection switch occurs on a two-fiber BLSR, the PSC of the protection span to which the traffic is switched increments, and when the switched traffic returns to its original working span from the protect span, the PSC of the protect span increments again.
