RSOHAISEN:
The receive section overhead AIS enable (RSOHAISEN) bit enables AIS insertion on RTOH
when carrying section overhead bytes. When RSOHAISEN is set to logic 1, all ones are
forced on the section overhead bytes when a LOF or LOS condition exists. When
RSOHAISEN is set to logic 0, no AIS are forced on the section overhead bytes regardless of
the alarm condition.
This bit should be set to logic 1 for normal operation.
RLOHAISEN:
The receive line overhead AIS enable (RLOHAISEN) bit enables AIS insertion on RTOH,
when carrying line overhead bytes. When RLOHAISEN is set to logic 1, all ones are forced
on the line overhead bytes when a LOF or LOS condition exists. When RLOHAISEN is set to
logic 0, no AIS are forced on the line overhead bytes regardless of the alarm condition.
This bit should be set to logic 1 for normal operation.
