latter procedure can be repeated until the framer has locked on the
right pattern (no extensive CRC errors).

Send AIS Towards System Interface
Sends AIS (blue alarm) via output RDO towards system interface.
This function is not influenced by bit FMR2.DAIS.

Specified number of errors in both FT framing and FS framing
lead to loss of sync (FRS0.LFA is set). In the case of FS bit
framing errors, bit FRS0.LMFA is set additionally. A complete
new synchronization procedure is initiated to regain pulseframe
alignment and then multiframe alignment.
Specified number of errors in FT framing has the same effect
as above. Specified number of errors in FS framing only
initiates a new search for multiframe alignment without
influencing pulseframe synchronous state (FRS0.LMFA is set).
AIS is automatically inserted into the data stream to RDO if
FALC54 is in asynchronous state.
Automatic AIS insertion is disabled. Furthermore, AIS insertion
can be initiated by programming bit FMR2.SAIS.
Normal operation
The payload loopback will loop the data stream from the
receiver section back to transmitter section. Looped data is
output on pin RDO. Data received at port XDI, SYPXQ and
XMFS will be ignored. With FMR4.TM=1 all 193 bits per frame
will be looped back. If FMR4.TM=0 the DL- or FS- or CRC- bits
will be generated internally. AIS is sent immediately on port
RDO by setting the FMR2.SAIS bit. During payload loop is
active the receive time-slot offset (registers RC1/0) should not
be changed.
