This register provides control and reports the status of the R8TD blocks.
FOCA
The force out-of-character-alignment bit (FOCA) control the operation of the character
alignment block in the R8TD block. A 0-1 transition on this bit forces the character alignment
block to the out-of-character-alignment state where it will search for the transport frame
alignment character (K28.5). Before another force operation can be performed, FOCA must
first be set to logic 0.
FOFA
The force out-of-frame-alignment bit (FOFA) controls the operation of the frame alignment
block in the R8TD block. A 0-1 transition on this bit forces the frame alignment block to the
out-of-frame-alignment state where it will search for the transport frame alignment character
(K28.5). Before another force operation can be performed, FOFA must first be set to logic 0.
OCAV
The out-of-character-alignment status bit (OCAV) reports the state of the character alignment
block in the R8TD block. OCAV is set high when the character alignment block is in the out-
of-character-alignment state. OCAV is set low when the character alignment block is in the
in-character-alignment state.
