nizer before sync is declared. Clearing RCR.3 causes
the synchronizer to search for F
T
patterns (101010...)
without cross-coupling the F
S
pattern. Frame sync will
be established using the F
T
information, while multi-
frame sync will be established only if valid F
S
informa-
tion is present. If no valid F
S
pattern is identified, the syn-
chronizer will move to the F
T
alignment, RLOS will go
low, and a false multiframe position may be indicated by
RMSYNC. RFER will indicate when the received S-bit
pattern does not match the assumed internal multiframe
alignment. This mode will be used in applications where
non-standard S-bit patterns exist. In such applications,
multiframe alignment information can be decoded ex-
ternally by using the S-bits present at RLINK.

NOTE:
1. Average Reframe Time is defined here as the average time it takes from the start of sync (rising edge of
RLOS) to the actual loading of the new alignment (on a multiframe edge) into the output receive timing.
