register.
`
1 - Indicates that the "Change of RFI-V Defect Condition" Interrupt has occurred since the last read of this register.
Bit 4 - Change of RDI-V Defect Condition Interrupt Status
This RESET-upon-READ bit-field indicates whether or not the "VT-De-Mapper" block has generated the
"Change of RDI-V Defect 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 RDI-V defect condition
Whenever the VT-De-Mapper block clears the RDI-V defect condition.
`
0 - Indicates that the "Change of RDI-V Defect Condition" Interrupt has NOT occurred since the last read of this
register.
`
1 - Indicates that the "Change of RDI-V Defect Condition" Interrupt has occurred since the last read of this register.
Bit 3 - Change of AIS-V Failure Condition Interrupt Status
This RESET-upon-READ bit-field indicates whether or not the "VT-De-Mapper" block has generated the "Change of
AIS-V Failure 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 AIS-V failure condition
Whenever the VT-De-Mapper block clears the AIS-V failure condition.
`
0 - Indicates that the "Change of AIS-V Failure Condition" Interrupt has NOT occurred since the last read of this
register.
`
1 - Indicates that the "Change of AIS-V Failure Condition" Interrupt has occurred since the last read of this register.
Bit 2 - Change of AIS-V Defect Condition Interrupt Status
This RESET-upon-READ bit-field indicates whether or not the "VT-De-Mapper" block has generated the
"Change of AIS-V Defect 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 AIS-V defect condition
Whenever the VT-De-Mapper block clears the AIS-V defect condition.
0 - Indicates that the "Change of AIS-V Defect Condition" Interrupt has NOT occurred since the last read of this
register.
1 - Indicates that the "Change of AIS-V Defect Condition" Interrupt has occurred since the last read of this
register.
Bit 1 - Change of VT Label Value Interrupt Status
This RESET-upon-READ bit-field indicates whether or not the "Change of VT Label Value" Interrupt has occurred since
the last read of this register. The VT-De-Mapper block will generate this interrupt anytime it has "accepted" a new VT
Label value (that it has received via the V5 byte within the incoming VT data-stream).
`
0 - Indicates that the "Change of VT Label Value" Interrupt has NOT occurred since the last read of this register.
`
1 - Indicates that the "Change of VT Label Value" Interrupt has occurred since the last read of this register.
Bit 0 - Change of DS1/E1 AIS Defect Condition Interrupt Status
This RESET-upon-READ bit-field indicates whether or not the "Change of DS1/E1 AIS Defect Condition"
Interrupt has occurred since the last read of this register. The VT-Mapper block will generate this interrupt in
response to any one of the following conditions.
Whenever the VT-Mapper block declares the DS1/E1 AIS Defect (with the Ingress Direction T1/E1 traffic).
Whenever the VT-Mapper block clears the DS1/E1 AIS Defect (within the Ingress Direction T1/E1 traffic)
`
0 - Indicates that the "Change of DS1/E1 AIS Defect Condition" Interrupt has NOT occurred since the last read of this
register.
`
1 - Indicates that the "Change of DS1/E1 AIS Defect Condition" Interrupt has occurred since the last read of this
register.
