OFAAIS
SETLCV
The Reserved bits must be set to their default value for proper operation.
Reserved
The out of frame alignment alarm indication signal (OFAAIS) is set high to force high-order
AIS signals in the R8TD egress data stream if the R8TD is in the out-of-frame-alignment
state. The R8TD egress data stream is left unaffected in the out-of-frame alignment state
when the OFFAIS is set low.
The SETLCV bit is used to introduce line code violations in the receive data stream. When
logic 1, SETLCV will induce a large number of LCVs on the data stream. When logic 0,
SETLCV will not alter the incoming data stream. This feature can be used to cause excessive
LCVs which in turn will force the R8TD to search for a new character alignment.
