0
Line Code Violation Interrupt Status. The Receive LIU Interrupt
Block will set this bit-field to 1 if it detects a Line Code Violation in
the incoming E1 data stream.
0 = Line Code Violation interrupt has not occurred since the last
read of this register.

Change in Receive Loss of Frame Condition Interrupt Status.
The receive E1 Framer block will set this bit-field to 1 if the Receive
E1 framer has transition into the In-Frame condition or Loss of
Frame condition.

of this register
1 = Change in RxLOF Interrupt has occurred since the last read of
this register
E1/ RxAIS Status
T1
Change in Receive AIS Condition Interrupt Status. The Receive
E1 Framer will generate the Change in AIS Condition interrupt if it
starts to detect the AIS pattern in the incoming data stream or if it no
longer detects the AIS pattern in the incoming data stream.
0 = Change in AIS Condition Interrupt has not occurred since the
last read of this register
1 = Change in AIS Condition Interrupt has occurred since the last
read of this register
E1/ RxYEL Status

Receipt of FAS Frame Yellow Alarm Interrupt Status.
The Receive E1 Framer will generate the FAS Frame Yellow Alarm
interrupt if it detects the FAS Frame Yellow Alarm in the incoming E1
data stream.
0 = FAS Frame Yellow Alarm interrupt has not occurred
1 = FAS Frame Yellow Alarm interrupt has occurred since the last
read of this register.
