8.6 Performance Monitoring for Optical Cards
The following sections define performance monitoring parameters and definitions for the OC-3, OC-12,
OC-48, and OC-192.
8.6.1 OC-3 Card Performance Monitoring Parameters
Figure 8-21 shows where overhead bytes detected on the ASICs produce performance monitoring
parameters for the OC-3 card.
Figure 8-21 PM read points on the OC-3 card
Note For PM locations relating to protection switch counts, see the GR-253-CORE document.

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.
