SDH-TO-PDH FRAMER/MAPPER WITH INTEGRATED 21-CHANNEL E1 SH LIU
BIT 7 - Auto Transmit AIS-V upon VT Path Trace Message Unstable 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 VT Path Trace Message Unstable 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 VT Path Trace Message Unstable defect condition.
1 - Configures the VT-De-Mapper block to automatically transmit the AIS-V indicator (via the "downstream" traffic)
whenever it declares the VT Path Trace Message Unstable 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 6 - Auto Transmit AIS-V upon TIM-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 TIM-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 TIM-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 TIM-V defect condition.

to automatically transmit the AIS-V indicator, in response to this defect condition.
BIT 5 - Auto Transmit AIS-V upon N1 Byte 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 detects an all "0" value on the received N1 Byte and declares the N1 Byte 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 N1 Byte 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 N1 Byte Alarm defect condition.
