In F12 (D4) format bit 1 in frame 12 is excluded from the synchronization process.
Summary of Frame Conditions (T1/J1)
Summary Frame Recover/Out of Frame Conditions (T1/J1)
Frame Recover Condition
only one FT pattern found, optional
forcing on next available FT framing
candidate
FMR2.SSP = 0:
Combined FT + FS framing search:
First searching for FT pattern with
optional forcing on next available
framing candidates and then for 2
consecutive correct FS pattern
FMR2.SSP = 1:
Separated FT + FS pattern search:
Loss of FT framing starts first
search for FT and then for 2
consecutive correct FS pattern
Loss of FS framing starts only the
FS pattern
FMR2.MCSP/SSP = 00:
only one FAS pattern found,
optional forcing on next available
FAS framing candidate with
discarding of all remaining framing
candidates.
FMR2.MCSP/SSP = 01:
3 consecutive correct multiframing
found independent of CRC6 errors.
FMR2.MCSP/SSP = 10:
choosing multiple framing pattern
step by step, optional forcing on
next available FAS framing pattern
with discarding only of the previous
assumed framing candidate.
FMR2.MCSP/SSP = 11:
FAS framing correctly found and
CRC6 check error free.
