This MIB module defines the managed objects and statistics
objects for physical layer characteristics of optical line
systems and optical transport devices.
Performance monitoring (PM) parameters are used to gather,
store, set thresholds for and report
performance data for early detection of problems.
Thresholds are used to set error levels for each PM parameter.
During the accumulation cycle, if the current value of a
performance monitoring parameter reaches or exceeds its
corresponding threshold value, a threshold crossing alarm (TCA)
is generated. The TCAs provide early detection of performance
degradation.
