FOCA

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.
