28-CHANNEL DS1/E1 FRAMER/LIU WITH DS3 MUX & VT-MAPPER - SONET APPLICATIONS
`
1 - Configures the VT-De-Mapper block to automatically transmit the AIS-V indicator (via the "downstream" traffic)
whenever it declares the LOP-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 1 - Auto Transmit AIS-V upon PLM-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 T1/E1 LIU Block), anytime (and for the duration
that) it declares the PLM-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 PLM-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 PLM-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 0 - Unused:
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 T1/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.

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 T1/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.
