Definition
Section Coding Violation (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, with each
error incrementing the current CV-S second register.
Section Errored Seconds (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.
