21.20 Performance Report Message
The performance monitor block monitors for errored second events and generates the one-second data for the
extended superframe (ESF) performance report message (PRM) (G.704 section 2.1.3.1.3.3, G.963, T1.231 sec-
tion 6.3, and T1.403 section 9.4.2.). The form of the PRM message is shown in
Table 587
below. The definition of
the fields is given in

Provides an indication to frame aligner (does not have to be
stored) to reframe (in CEPT and ESF modes) based on CRC
errors and to re-establish multiframe alignment (in CEPT)
based on bit 0 of the NOTFAS frames (except 15 and 17).
Provides indication to frame formatter to set RAI.
Provides indication to frame formatter to set AIS.
