The framing structure is defined by the contents of time-slot 0 (refer to Table 4-8).

4.7.1.1
Synchronization status is reported via bit FRS.LFA. Framing errors are counted by the
Framing Error Counter (FEC). Asynchronous state is reached after detecting 3 or 4
consecutive incorrect FAS words or 3 or 4 consecutive incorrect service words (bit 2 = 0
in time-slot 0 of every other frame not containing the frame alignment word), the
selection is done via bit RFMR.SSC. Additionally, the service word condition can be
disabled. When the framer lost its synchronization an status bit FRS.LFA is generated.
In asynchronous state, counting of framing errors will be stopped.
The resynchronization procedure starts automatically after reaching the asynchronous
state. Additionally, it may be invoked user controlled via bit RCMDR.FRS (Force
Resynchronization: the FAS word detection is interrupted. In connection with the above
conditions this will lead to asynchronous state. After that, resynchronization starts
automatically).
