DESCRIPTION
Receive AIS Defect Indicator:
This READ-ONLY bit-field indicates whether or not the Frame
Synchronizer block is currently detecting the AIS pattern in its
incoming path.
0 - Frame Synchronizer block is NOT currently detecting an AIS
pattern in its incoming path.
1 - Frame Synchronizer block is currently detecting an AIS pat-
tern in its incoming path.
Receive LOS Defect Indicator:
This READ-ONLY bit-field indicates whether or not the Frame
Synchronizer block is currently detecting the LOS condition, in its
incoming path.
0 - Frame Synchronizer block is NOT currently declaring an LOS
condition in its incoming path.
1 - Frame Synchronizer block is currently detecting an LOS con-
dition in its incoming path.
Receive Idle Signal Indicator:
This READ-ONLY bit-field indicates whether or not the Frame
Synchronizer block is currently detecting the DS3 Idle pattern, in
its incoming path.
0 - Frame Synchronizer block is NOT currently detecting the DS3
Idle Pattern, in its incoming path.
1 - Frame Synchronizer block is currently detecting the DS3 Idle
Pattern in its incoming path.
Receive OOF Defect Indicator:
This READ-ONLY bit-field indicates whether or not the Frame
Synchronizer block is currently declaring an OOF (Out of Frame)
condition.
0 - Frame Synchronizer block is NOT currently declaring the
OOF condition.
1 - Frame Synchronizer block is currently declaring the OOF
condition.
