4.6.1
The allocation of the FT bits (bit 1 of frames 1 and 3) for frame alignment signal is shown
in Table 4-5.
The FS bit may be used for signaling.
Remote alarm (yellow alarm) is indicated by setting bit(2) to ‘0’ in each channel.

Synchronization Procedure
For multiframe synchronization, the terminal framing bits (FT bits) are observed. The
synchronous state is reached if at least one terminal framing candidate is definitely
found, or the synchronizer is forced to lock onto the next available candidate
(RCMDR.FRS).
