These register bits are valid for both master and slave slices. Please refer to individual bit for
details.
RSOHAISEN
The receive section overhead AIS enable (RSOHAISEN) bit enables AIS insertion on
RTOH and RSLD when carrying section overhead bytes. When RSOHAISEN is set to
logic 1, all ones are forced on the section overhead bytes when AIS-L is declared. When
RSOHAISEN is set to logic 0, no AIS are forced on the section overhead bytes regardless of
the AIS-L status
.
This bit should be set to logic 1 for normal operation. This bit is valid for master and slave
slices.
RLOHAISEN
The receive line overhead AIS enable (RLOHAISEN) bit enables AIS insertion on RTOH,
RLD and RSLD when carrying line overhead bytes. When RLOHAISEN is set to logic 1,
all ones are forced on the line overhead bytes when AIS-L is declared. When RLOHAISEN
is set to logic 0, no AIS are forced on the line overhead bytes regardless of the AIS-L status.
This bit should be set to logic 1 for normal operation. This bit is valid for master and slave
slices.
