BIT [7:6] - Reserved:
BIT 5 - Auto Transmit AIS-V upon AIS-V 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 AIS-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 AIS-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 AIS-V defect condition.
N
OTE
:
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 4 - Auto Transmit AIS-V upon UNEQ-V 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 UNEQ-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 UNEQ-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 UNEQ-V defect condition.

BIT 3 - Reserved:
BIT 2 - Auto Transmit AIS-V upon LOP-V 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 LOP-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 LOP-V defect condition.
1 - Configures the VT-De-Mapper block to automatically transmit the AIS-V indicator (via the "downstream" traffic)
