Line Loopback Disable Detect. This bit will be set when a framed or unframed repeating
pattern of 001 has been detected during a 48 millisecond interval. Up to fifteen errors are
permitted per integration period.Note that the code detected is dependent on Receive
Loopback Deactivate Code Match (YF0).
T1DM Received R bit. This bit is used for AT&T 8 KB/s communications channel. This bit
will be received in bit 1 of timeslot 24 of the receive PCM24 stream in T1DM mode.
T1DM Received Yellow Alarm. If this bit is 0 a T1DM yellow alarm has been detected in bit
2 of timeslot 24 of the receive PCM24 stream in T1DM mode.

Bit Oriented Message Received. This bit is set when a Received Bit Oriented
Message is received.
Receive Bit Oriented Match. This bit is set if there is a match between the Received
Bit Oriented Message and Receive Bit oriented Match register.
Receive Bit Oriented Message. This is the bit oriented message received. This
register is updated after 8 out of 10 messages are received.
