Line Code violation interrupt enable
This bit permits the user to either enable or disable the “Line Code Viola-
tion” interrupt within the XRT86VL38 device. If the user enables this inter-
rupt, then the Receive T1 Framer block will generate an interrupt when Line
Code Violation is detected.
0 = Disables the interrupt generation when Line Code Violation is detected.
1 = Enables the interrupt generation when Line Code Violation is detected.

Change in Loss of Frame Condition interrupt enable
This bit permits the user to either enable or disable the “Change in Loss of
Frame Condition” Interrupt, within the XRT86VL38 device. If the user
enables this interrupt, then the Receive T1 Framer block will generate an
interrupt in response to either one of the following conditions.
1. The instant that the Receive T1 Framer block declares the Loss of
Frame condition.
2. The instant that the Receive T1 Framer block clears the Loss of
Frame condition.
0 – Disables the “Change in Loss of Frame Condition” Interrupt.
1 – Enables the “Change in Loss of Frame Condition” Interrupt.

Change in AIS Condition interrupt enable
This bit permits the user to either enable or disable the “Change in AIS
Condition” Interrupt, within the XRT86VL38 device. If the user enables this
interrupt, then the Receive T1 Framer block will generate an interrupt in
response to either one of the following conditions.
1. The instant that the Receive T1 Framer block declares the AIS
condition.
2. The instant that the Receive T1 Framer block clears the AIS
condition.
0 – Disables the “Change in AIS Condition” Interrupt.
1 – Enables the “Change in AIS Condition” Interrupt.

Change in Yellow alarm Condition interrupt enable
This bit permits the user to either enable or disable the “Change in Yellow
Alarm Condition” Interrupt, within the XRT86VL38 device. If the user
enables this interrupt, then the Receive T1 Framer block will generate an
interrupt in response to either one of the following conditions.
1. The instant that the Receive T1 Framer block declares the Yellow
Alarm condition.
2. The instant that the Receive T1 Framer block clears the Yellow
Alarm condition.
0 – Disables the “Change in Yellow Alarm Condition” Interrupt.
1 – Enables the “Change in Yellow Alarm Condition” Interrupt.
