28-CHANNEL DS1/E1 FRAMER/LIU WITH DS3 MUX & VT-MAPPER - SONET APPLICATIONS
REV. P1.0.6
BIT 7 - Unused
BIT 6 - Transmit Path AIS (Downstream) upon Declaration of the Unstable C2 Byte Defect Condition
This READ/WRITE bit-field is used to configure the Receive STS-1 POH Processor block to automatically transmit the
Path AIS (AIS-P) Indicator via the downstream traffic (e.g., towards each of the 28 Egress Direction Transmit DS1/E1
Framer blocks), anytime (and for the duration that) it declares the Unstable C2 Byte Defect condition within the incoming
STS-1/STS-3 data-stream.
`
0 - Does not configure the Receive STS-1 POH Processor block to automatically transmit the AIS-P indicator (via the
downstream traffic) whenever it declares the Unstable C2 Byte defect condition.
`
1 - Configures the Receive STS-1 POH Processor block to automatically transmit the AIS-P indicator (via the
downstream traffic) whenever it declares the Unstable C2 Byte defect condition.
N
OTE
:
The user must also set BIT 0 (Transmit AIS-P Enable) to 1 to configure the Receive STS-1 POH Processor
block to automatically transmit the AIS-P indicator, in response to this defect condition.
BIT 5 - Transmit Path AIS (Downstream) upon Declaration of the UNEQ-P (Path - Unequipped) Defect Condition
This READ/WRITE bit-field is used to configure the Receive STS-1 POH Processor block to automatically transmit the
Path AIS (AIS-P) Indicator via the downstream traffic (e.g., towards each of the 28 Egress Direction Transmit DS1/E1
Framer blocks), anytime (and for the duration that) it declares the UNEQ-P defect condition.
`
0 - Does not configure the Receive STS-1 POH Processor block to automatically transmit the AIS-P indicator (via the
downstream traffic) whenever it declares the UNEQ-P defect condition.
`
1 - Configures the Receive STS-1 POH Processor block to automatically transmit the AIS-P indicator (via the
downstream traffic) whenever it declares the UNEQ-P defect condition.
N
OTE
:
The user must also set BIT 0 (Transmit AIS-P Enable) to 1 to configure the Receive STS-1 POH Processor
block to automatically transmit the AIS-P indicator, in response to this defect condition.
BIT 4 - Transmit Path AIS (Downstream) upon Declaration of the PLM-P (Path - Payload Label Mismatch) Defect
Condition
This READ/WRITE bit-field is used to configure the Receive STS-1 POH Processor block to automatically transmit the
Path AIS (AIS-P) Indicator via the downstream traffic (e.g., towards each of the 28 Egress Direction Transmit DS1/E1
Framer blocks), anytime (and for the duration that) it declares the PLM-P defect condition.
`
0 - Does not configure the Receive STS-1 POH Processor block to automatically transmit the AIS-P indicator (via the
downstream traffic) whenever it declares the PLM-P defect condition.
`
1 - Configures the Receive STS-1 POH Processor block to automatically transmit the AIS-P indicator (via the
downstream traffic) whenever it declares the PLM-P defect condition.Note
N
OTE
:
The user must also set BIT 0 (Transmit AIS-P Enable) to 1 to configure the Receive STS-1 POH Processor
block to automatically transmit the AIS-P indicator, in response to this defect condition.
BIT 3 - Transmit Path AIS (Downstream) upon declaration of the Path Trace Message Unstable Defect Condition
This READ/WRITE bit-field is used to configure the Receive STS-1 POH Processor block to automatically transmit the
Path AIS (AIS-P) Indicator via the downstream traffic (e.g., towards each of the 28 Egress Direction Transmit DS1/E1
Framer blocks), anytime (and for the duration that) it declares the Path Trace Message Unstable defect condition within
