NAME AND DESCRIPTION
Transmit Side Elastic Store Full. Set when the transmit side
elastic store buffer fills and a frame is deleted.
Transmit Side Elastic Store Empty. Set when the transmit side
elastic store buffer empties and a frame is repeated.
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 Side Elastic Store Full. Set when the receive side
elastic store buffer fills and a frame is deleted.
Receive Side Elastic Store Empty. Set when the receive side
elastic store buffer empties and a frame is repeated.
CRC Resync Criteria Met. Set when 915/1000 code words are
received in error.
FAS Resync Criteria Met. Set when 3 consecutive FAS words
are received in error.
CAS Resync Criteria Met. Set when 2 consecutive CAS MF
alignment words are received in error.
