Receive Gain Monitor Bit 1. See the Level Indication table below for level indication.
Receive Gain Monitor Bit 0. See the Level Indication table below for level indication.
Jitter Attenuator Limit Trip. Set when the jitter attenuator FIFO reaches to within 4 bits of
its limit; useful for debugging jitter attenuation operation.
Receive Elastic Store Full. Set when the receive elastic store buffer fills and a frame is
deleted.
Receive Elastic Store Empty. Set when the receive elastic store buffer empties and a frame
is repeated.
CRC Resync Criteria Met. Set when 915/1000 codewords are received in error.
FAS Resync Criteria Met. Set when three consecutive FAS words are received in error.
CAS Resync Criteria Met. Set when two consecutive CAS MF alignment words are
received in error.
