BIT 4 - Auto Transmit AIS-V upon N2 IAIS Alarm Defect:
This READ/WRITE bit-field permits the user to configure the VT-De-Mapper block to automatically transmit the AIS-V
indicator via the "Egress Direction" traffic (e.g., towards the Transmit E1 LIU Block), anytime (and for the duration that)
it declares the N2 Incoming AIS Alarm defect condition within the incoming VT-data-stream.
0 - Does not configure the VT-De-Mapper block to automatically transmit the AIS-V indicator (via the "downstream"
traffic) whenever it declares the N2 Incoming AIS Alarm defect condition.
1 - Configures the VT-De-Mapper block to automatically transmit the AIS-V indicator (via the "downstream" traffic)
whenever it declares the N2 Incoming AIS Alarm defect condition.

:
The user must also set Bit 0 (Auto Transmit AIS-V Enable) within the "Channel Control - VT-De-Mapper Block -
Egress Direction - Receive VT Auto AIS Control" Register to "1" in order to configure the VT-De-Mapper block
to automatically transmit the AIS-V indicator, in response to this defect condition.
BIT 3 - Auto Transmit AIS-V upon TC LOMF-V Alarm Defect:
This READ/WRITE bit-field permits the user to configure the VT-De-Mapper block to automatically transmit the AIS-V
indicator via the "Egress Direction" traffic (e.g., towards the Transmit E1 LIU Block), anytime (and for the duration that)
it declares the TC LOMF-V defect condition within the incoming VT-data-stream.
0 - Does not configure the VT-De-Mapper block to automatically transmit the AIS-V indicator (via the "downstream"
traffic) whenever it declares the TC LOMF-V defect condition.
1 - Configures the VT-De-Mapper block to automatically transmit the AIS-V indicator (via the "downstream" traffic)
whenever it declares the TC LOMF-V defect condition.

BIT 2 - Auto Transmit AIS-V upon TC API-V Message Mismatch Defect:
This READ/WRITE bit-field permits the user to configure the VT-De-Mapper block to automatically transmit the AIS-V
indicator via the "Egress Direction" traffic (e.g., towards the Transmit E1 LIU Block), anytime (and for the duration that)
it declares the TC API-V Message Mismatch defect condition within the incoming VT-data-stream.
0 - Does not configure the VT-De-Mapper block to automatically transmit the AIS-V indicator (via the "downstream"
traffic) whenever it declares the TC API-V Message Mismatch defect condition.
1 - Configures the VT-De-Mapper block to automatically transmit the AIS-V indicator (via the "downstream" traffic)

BIT 1 - Auto Transmit AIS-V upon TC UNEQ-V Indication Signal Condition:
This READ/WRITE bit-field permits the user to configure the VT-De-Mapper block to automatically transmit the AIS-V
indicator via the "Egress Direction" traffic (e.g., towards the Transmit E1 LIU Block), anytime (and for the duration that)
it declares the TC UNEQ-V Indication Signal condition within the incoming VT-data-stream.
0 - Does not configure the VT-De-Mapper block to automatically transmit the AIS-V indicator (via the "downstream"
