28-CHANNEL DS1/E1 FRAMER/LIU WITH DS3 MUX & VT-MAPPER - SONET APPLICATIONS
BIT 1- Change of AIS-L (Line AIS) Defect Condition Interrupt Enable
This READ/WRITE bit-field is used to either enable or disable the Change of AIS-L Defect Condition interrupt. If this
interrupt is enabled, then the XRT86SH328 will generate an interrupt in response to either of the following conditions.
When the Receive STS-1/STS-3 TOH Processor block declares the AIS-L defect condition.·
When the Receive STS-1/STS-3 TOH Processor block clears the AIS-L defect condition.
`
0 - Disables the Change of AIS-L Defect Condition Interrupt.
`
1 - Enables the Change of AIS-L Defect Condition Interrupt.
BIT 0 - Change of RDI-L (Line Remote Defect Indicator) Defect Condition Interrupt Enable
This READ/WRITE bit-field is used to either enable or disable the Change of RDI-L Defect Condition interrupt. If this
interrupt is enabled, then the XRT86SH328 will generate an interrupt in response to either of the following conditions.·
When the Receive STS-1/STS-3 TOH Processor block declares the RDI-L defect condition.· When the Receive STS-
1/STS-3 TOH Processor block clears the RDI-L defect condition.
`
0 - Disables the Change of RDI-L Defect Condition Interrupt.
`
1 - Enables the Change of RDI-L Defect Condition Interrupt.
BIT 7 - New S1 Byte Value Interrupt Enable
This READ/WRITE bit-field is used to enable or disable the New S1 Byte Value Interrupt.
If this interrupt is enabled, then the Receive STS-1/STS-3 TOH Processor block will generate this interrupt anytime it
receives and accepts a new S1 byte value. The Receive STS-1/STS-3 TOH Processor block will accept a new S1 byte
after it has received it for 8 consecutive STS-1/STS-3 frames.
`
0 - Disables the New S1 Byte Value Interrupt.
`
1 - Enables the New S1 Byte Value Interrupt.
BIT 6 - Change in S1 Byte Unstable Defect Condition Interrupt Enable
This READ/WRITE bit-field is used to either enable or disable the Change in S1 Byte Unstable Defect Condition
Interrupt..
If the user enables this bit-field, then the Receive STS-1/STS-3 TOH Processor block will generate an interrupt in
response to either of the following conditions
When the Receive STS-1/STS-3 TOH Processor block declares the S1 Byte Unstable defect condition
When the Receive STS-1/STS-3 TOH Processor block clears the S1 Byte Unstable defect condition.
`
0 - Disables the Change in S1 Byte Unstable Defect Condition Interrupt.
`
1 - Enables the Change in S1 Byte Unstable Defect Condition Interrupt.
BIT 5 - Change in Section Trace Message Unstable defect condition Interrupt Enable
This READ/WRITE bit-field is used to either enable or disable the Change in Section Trace Message Unstable Defect
Condition Interrupt.
