YES
CRC-to-non-CRC interworking. Maintain primary
basic frame alignment. Continue to send CRC-4
data, but stop CRC processing. E-bits set to ‘0’.
Indicate CRC-to-non-CRC operation. Note 7.
Search for primary basic frame
alignment signal RAI=1, Es=0.
Out of synchronization
Verify Bit 2 of non-frame
alignment signal.
Parallel search for new basic frame
alignment signal.

CRC-to-CRC interworking. Re-align to new basic
frame alignment. Start CRC-4 processing. E-bits set
as per G.704 and I.431. Indicate CRC synchronization
achieved.
Notes 7& 8.
Signalling multi-frame alignment
Primary basic frame synchronization
acquired. Enable traffic RAI=0, E’s=0. Start
loss of primary basic frame alignment
checking. Notes 7 & 8.
YES
CRC-4 multi-frame alignment
YES
Verify second occurrence of
frame alignment signal.
Start 8 msec timer.
Note 7.
Multiframe synchronization
acquired as per G.732.
Note 7.
Find two CRC frame
alignment signals.
Note 7.
Check for two consecutive errored
multiframe alignment signals.
Notes 7 & 8.
