Reading this register returns the current state value of the OOF, OOSMF and
OOCMF FRMR framing status.
OOF:
The OOF bit is a logic one when basic frame alignment has been lost. The
OOF bit goes to a logic zero once frame alignment has been regained.
OOSMF:
The OOSMF bit is a logic one when the signaling multiframe alignment has
been lost. The OOSMF bit becomes a logic zero once signaling multiframe
has been regained.
OOCMF:
The OOCMF bit is a logic one when the CRC multiframe alignment has been
lost. The OOCMF bit becomes a logic zero once CRC multiframe has been
regained.
8MSDIS:
The 8MSDIS bit controls the ability of the 8 ms timer to initiate a reframe
when CRC multi-frame alignment cannot be found. When 8MSDIS is set to
logic 0, the 8 ms timer will initiate a reframe when the CRC Multi-frame Find
algorithm has been active for more than 8 ms. When 8MSDIS is set to logic
1, the 8 ms timer will not initiate a reframe when the CRC Multi-frame Find
algorithm has been active for more than 8 ms.
