Patent ID: 6894801

Claim:
A method comprising: frame-synchronizing incoming facsimile information to delineate logical facsimile adaptation frames (“LFAFs”), the frame-synchronization including locating a synchronization (“SYNCH”) frame containing a bit-rotated version of a unique synchronization sequence, the bit-rotated version comprising the unique synchronization sequence bit-rotated by a degree between zero bits and a predetermined number of bits; determining a degree of bit-rotation of the SYNCH frame by observing the degree of bit-rotation of the bit-rotated version of the unique synchronization sequence in the SYNCH frame compared to the unique synchronization sequence with zero bit-rotation; identifying a status (“STATUS”) frame; inferring that the status frame is bit-rotated to the same degree as the SYNCH frame; and compensating for the inferred degree of bit-rotation of the STATUS frame using the observed degree of bit-rotation.
