Performance Monitoring
Performance-monitoring parameters (PMs) are used by service providers to gather, store, threshold, and
report performance data for early detection of problems. In this chapter, PM parameters and concepts
are defined for both electrical cards and optical cards.
For information about Ethernet PMs, see
can also be found under Digital transmission surveillance, in Telcordia's GR-1230-CORE,
GR-820-CORE, and GR-253-CORE documents and the ANSI document entitled Digital Hierarchy -
Layer 1 In-Service Digital Transmission Performance Monitoring.
