repeating pattern ...00111000111000...(00111X0 if CCR.3–YELMD–is equal to a 1). In this mode, F
T
and F
S
patterns must be correctly identified by the synchronizer 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 multiframe sync will be established only if valid
F
S
information is present. If no valid F
S
pattern is identified, the synchronizer 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 externally by using the S-bits present at RLINK.

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.
