CRC Re-synchronization Criteria:
These READ/WRITE bit-field determine the criteria of Loss of
CRC Multi-frame Synchronization.
When these bits are set to 00:
If four consecutive CRC Multi-frame Alignment Signal errors in
the incoming frames are detected, the framer will declare Loss of
CRC Multi-frame Synchronization.
When these bits are set to 01:
If two consecutive CRC Multi-frame Alignment Signal errors in
the incoming frames are detected, the framer will declare Loss of
CRC Multi-frame Synchronization.
When these bits are set to 10:
If eight consecutive CRC Multi-frame Alignment Signal errors in
the incoming frames are detected, the framer will declare Loss of
CRC Multi-frame Synchronization.
When these bits are set to 11:
If 915 or more consecutive CRC Multi-frame Alignment Signal
errors in the incoming frames are detected in one second, the
framer will declare Loss of CRC Multi-frame Synchronization.
