28-CHANNEL DS1/E1 FRAMER/LIU WITH DS3 MUX & VT-MAPPER - SONET APPLICATIONS
REV. P1.0.6
below.
Bits 7 - 6 - Unused:
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 T1/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 T1/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.
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 3 - Unused:
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 T1/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.
