The performance monitoring process
...................................................................................................................................................................................................................................
Process description
The performance monitoring process is a three-stage process:
Primary processing
Fundamental parameters are derived from errors detected in the transport signal,
classified into bit errors and defects, and accumulated over one-second periods.
Parameter processing
Near-end and far-end performance parameters are calculated based on the evaluation
and correlation of the fundamental parameters obtained during the primary processing.
Please refer to “Available PM data” (p. 10-27).
Binning and reporting
In the binning and reporting phase, the performance parameters obtained during the
parameter processing are stored in accumulation registers (or “bins”) over 15-minutes
and 24-hours observation periods.
For each performance monitoring point (cf. “Performance measurements” (p. 10-8)), 16
recent (or history) bins for 15-minutes measurements and one recent bin for 24-hours
measurements are stored in the NE.
