2 - OPERATION
2.6 - Performance processing
Performance processing consists in supervising the following monitoring ports:
for local equipment:
regeneration section (byte B1) ("near end working (protection) RS"), multiplex section (byte B2) ("near end working (protection) MS"),
SVC3 tributary paths ("near end Low Path Virtual Container"),
VC12 tributary paths (byte V5) ("near end Low Path Virtual Container"),
for the remote equipment:
multiplex section (byte M1) ("far end working (protection) MS"), VC3 tributary paths ("far end Low Path Virtual Container")
VC12 tributary paths (byte V5) ("far end Low Path Virtual Container").
Performance processing includes the following functions:
calculation of the number of errored blocks (or bit errors) on local and remote faults and monitoring of the appearance faults over a one second period
calculation and determination of the ES (Errored Second), SES (Severely Errored Second), BBE (Background Block Error) and UAS (UnAvailable Second) states for each monitoring
Spoint,
generation for each monitoring point of
Determination of ES, SES and UAS performance states:
For each of the monitoring points, the following states are:
- ES (Errored Second) | : number of seconds with at least one error detected |
| in a 1 s period or one fault, |
- SES (Severely Errored Second) | : number of severely errored seconds, |
An SES is a second for which the number of errors exceeds a defined threshold or during which at least one fault is detected.
