BIT 6 - Change of TC RDI-V Defect Interrupt Status:
This RESET-upon-READ bit-field indicates whether or not the "VT-De-Mapper" block has generated the "Change of
Tandem Connection Remote Defect Indicator Condition" Interrupt since the last read of this register. The VT-De-
Mapper block will generate this interrupt in response to either of the following conditions.
Whenever the VT-De-Mapper block declares the TC RDI-V defect condition.
Whenever the VT-De-Mapper block clears the TC RDI-V defect condition.
0 - Indicates that the "Change of TC RDI-V Defect Condition" Interrupt has NOT occurred since the last read of this
register.
1 - Indicates that the "Change of TC RDI-V Defect Condition" Interrupt has occurred since the last read of this register.
BIT 5 - Change of TC ODI-V Defect Interrupt Status:
This RESET-upon-READ bit-field indicates whether or not the "VT-De-Mapper" block has generated the "Change of
Tandem Connection Outgoing Defect Indicator Condition" Interrupt since the last read of this register. The VT-De-
Mapper block will generate this interrupt in response to either of the following conditions.
Whenever the VT-De-Mapper block declares the TC ODI-V defect condition.
Whenever the VT-De-Mapper block clears the TC ODI-V defect condition.
0 - Indicates that the "Change of TC ODI-V Defect Condition" Interrupt has NOT occurred since the last read of this
register.
1 - Indicates that the "Change of TC ODI-V Defect Condition" Interrupt has occurred since the last read of this register.
BIT 4 - Change of TC API-V Message Mismatch Defect Interrupt Status:
This RESET-upon-READ bit-field indicates whether or not the "VT-De-Mapper" block has generated the "Change of
Tandem Connection Access Point Identifier Message Mismatch Condition" Interrupt since the last read of this register.
The VT-De-Mapper block will generate this interrupt in response to either of the following conditions.
Whenever the VT-De-Mapper block declares the TC API-V Message Mismatch defect condition.
Whenever the VT-De-Mapper block clears the TC API-V Message Mismatch defect condition.
0 - Indicates that the "Change of TC API-V Message Mismatch Defect Condition" Interrupt has NOT occurred since
the last read of this register.
