FOCA
FOCA:
The force out-of-character-alignment bit (FOCA) controls the operation of the character
alignment circuit on a serial link. A transition from logic zero to logic one in this bit forces the
receiver to the out-of-character-alignment state where it will search for the transport frame
alignment character (K28.5). This bit must be manually set to logic zero before it can be used
again.
FOFA:
The force out-of-frame-alignment bit (FOFA) controls the operation of the frame alignment
circuit. A transition from logic zero to logic one in this bit forces the receiver to the out-of-
frame-alignment state where it will search for the transport frame alignment character
(K28.5). This bit must be manually set to logic zero before it can be used again.
