BIT 3 - Transmit TC RDI-V upon TC UNEQ-V:
This READ/WRITE bit-field permits the user to configure the VT-Mapper block to automatically transmit the Tandem
Connection RDI Code on the VC2 N2 byte towards the remote VT PTE whenever (and for the duration that) the
corresponding VT-De-Mapper block declares the TC UNEQ-V defect condition.
0 - Configures the VT-Mapper block to NOT automatically transmit the Tandem Connection RDI Code (via the N2
byte) whenever (and for the duration that) the corresponding VT-De-Mapper block declares the TC UNEQ-V defect
condition.
1 - Configures the VT-Mapper block to automatically transmit the Tandem Connection RDI Code (via the N2 byte)
whenever (and for the duration that) the corresponding VT-De-Mapper block declares the TC UNEQ-V defect condition.
BIT 2 - Transmit TC RDI-V upon Incoming AIS-V:
This READ/WRITE bit-field permits the user to configure the VT-Mapper block to automatically transmit the Tandem
Connection RDI Code on the VC2 N2 byte towards the remote VT PTE whenever (and for the duration that) the
corresponding VT-De-Mapper block detects the Incoming AIS-V defect condition.
0 - Configures the VT-Mapper block to NOT automatically transmit the Tandem Connection RDI Code (via the N2
byte) whenever (and for the duration that) the corresponding VT-De-Mapper block detects the Incoming AIS defect
condition.
1 - Configures the VT-Mapper block to automatically transmit the Tandem Connection RDI Code (via the N2 byte)
whenever (and for the duration that) the corresponding VT-De-Mapper block detects the Incoming AIS defect condition.
BIT 1 - Transmit TC RDI-V upon TC API-V Message Mismatch:
This READ/WRITE bit-field permits the user to configure the VT-Mapper block to automatically transmit the Tandem
Connection RDI Code on the VC2 N2 byte towards the remote VT PTE whenever (and for the duration that) the
corresponding VT-De-Mapper block declares the TC API-V Message Mismatch defect condition.
0 - Configures the VT-Mapper block to NOT automatically transmit the Tandem Connection RDI Code (via the N2
byte) whenever (and for the duration that) the corresponding VT-De-Mapper block declares the TC API-V Message
Mismatch defect condition.
1 - Configures the VT-Mapper block to automatically transmit the Tandem Connection RDI Code (via the N2 byte)
whenever (and for the duration that) the corresponding VT-De-Mapper block declares the TC API-V Message Mismatch
defect condition.
BIT 0 - Transmit TC RDI-V upon TC API-V Message Unstable Defect:
This READ/WRITE bit-field permits the user to configure the VT-Mapper block to automatically transmit the Tandem
Connection RDI Code on the VC2 N2 byte towards the remote VT PTE whenever (and for the duration that) the
corresponding VT-De-Mapper block declares the TC API-V Message Unstable defect condition.
0 - Configures the VT-Mapper block to NOT automatically transmit the Tandem Connection RDI Code (via the N2
byte) whenever (and for the duration that) the corresponding VT-De-Mapper block declares the TC API-V Message
Unstable defect condition.
1 - Configures the VT-Mapper block to automatically transmit the Tandem Connection RDI Code (via the N2 byte)
whenever (and for the duration that) the corresponding VT-De-Mapper block declares the TC API-V Message Unstable
defect condition.
