Extended CRC4 to Non CRC4 Interworking
Only valid in multiframe format. This bit selects the reaction of the
synchronizer after the 400 msec timeout has been elapsed and starts
transmitting a remote alarm if FMR2.AXRA is set.

The CRC4 to Non CRC4 interworking is done as described in
the multiframe.
ITU-T G. 706 Annex B.
The interworking is done according to ITU-T G. 706 with the
exception that
multiframing even if the 400 msec timer is expired. Switching
into doubleframe format is disabled. If FMR2.AXRA is set the
remote alarm bit will be active in the outgoing data stream until
the multiframe is found.
Normal operation.
Idle channel mode. The contents of the selected time-slot is
overwritten by the idle channel code defined via register IDLE.
