5.4.4.1
In the synchronous state terminal framing (FT bits) and multiframing (FS bits) are
observed, independently. Further reaction on framing errors depends on the selected
synchronization/resynchronization procedure (via bit FMR2.SSP):
• FMR2.SSP = ‘0’: terminal frame and multiframe synchronization are combined.
• FMR2.SSP = ‘1’: terminal frame and multiframe synchronization are separated
Data Sheet
This bit can be used for remote alarm indication, if FMR0.SRAF = 1 is set. In this case, this FS bit is not used
to regain synchronization.
Two errors within 4/5/6 framing bits (via bits FMR4.SSC1/0) of one of the above leads
to the asynchronous state for terminal framing and multiframing. Additionally to the bit
FRS0.LFA, loss of multiframe alignment is reported via bit FRS0.LMFA.
The resynchronization procedure starts with synchronizing upon the terminal framing.
If the pulse framing has been regained, the search for multiframe alignment is
initiated. Multiframe synchronization has been regained after two consecutive correct
multiframe patterns have been received.
Two errors within 4/5/6 terminal framing bits lead to the same reaction as described
above for the “combined” mode.
Two errors within 4/5/6 multiframing bits lead to the asynchronous state only for the
multiframing. Loss of multiframe alignment is reported via bit FRS0.LMFA. The state
of terminal framing is not influenced.
Now, the resynchronization procedure includes only the search for multiframe
alignment. Multiframe synchronization has been regained after two consecutive
correct multiframe patterns have been received.
