BIT 7 - Transmit Path AIS upon Declaration of the Section Trace Message Unstable Defect Condition
This READ/WRITE bit-field is used to configure the Receive STM-0 TOH Processor block to automatically transmit the
Path AIS (AIS-P) Indicator via the downstream traffic (e.g., towards the Receive STM-0 POH Processor block), anytime
it declares the Section Trace Message Unstable defect condition within the incoming STM-0 data-stream.
0 - Does not configure the Receive STM-0 TOH Processor block to automatically transmit the AIS-P indicator (via the
downstream traffic) whenever (and for the duration that) it declares the Section Trace Message Unstable defect
condition.
1 - Configures the Receive STM-0 TOH Processor block to automatically transmit the AIS-P indicator (via the
downstream traffic) whenever (and for the duration that) it declares the Section Trace Message Unstable defect
condition.
N
OTE
:
The user must also set BIT 0 (Transmit AIS-P Enable) to 1 to configure the Receive STM-0 TOH Processor
block to automatically transmit the AIS-P indicator, in response to this defect condition.
BIT 6 - Transmit Path AIS (AIS-P) upon Declaration of the Section Trace Message Mismatch Defect Condition
This READ/WRITE bit-field is used to configure the Receive STM-0 TOH Processor block to automatically transmit the
Path AIS (AIS-P) Indicator via the downstream traffic (e.g., towards the Receive STM-0 POH Processor blocks),
anytime (and for the duration that) it declares the Section Trace Message Mismatch defect condition within the incoming
STM-0 data stream.
0 - Does not configure the Receive STM-0 TOH Processor block to automatically transmit the AIS-P indicator (via the
downstream traffic) whenever it declares the Section Trace Mismatch defect condition.
1 - Configures the Receive STM-0 TOH Processor block to automatically transmit the AIS-P indicator (via the
downstream traffic) whenever (and for the duration that) it declares the Section Trace Message Mismatch defect
condition.
N
OTE
:
The user must also set BIT 0 (Transmit AIS-P Enable) to 1 to configure the Receive STM-0 TOH Processor
block to automatically transmit the AIS-P indicator, in response to this defect condition.
BIT 5 - Transmit Path AIS upon declaration of the Signal Failure (SF) defect condition
This READ/WRITE bit-field is used to configure the Receive STM-0 TOH Processor block to automatically transmit a
Path AIS (AIS-P) Indicator via the downstream traffic (e.g., towards the Receive STM-0 POH Processor block), anytime
(and for the duration that) it declares the SF defect condition.
0 - Does not configure the Receive STM-0 TOH Processor block to transmit the AIS-P indicator (via the downstream
traffic) upon declaration of the SF defect.
1 - Configures the Receive STM-0 TOH Processor block to automatically transmit the AIS-P indicator (via the
downstream traffic) anytime (and for the duration that) it declares the SF defect condition.
N
OTE
:
The user must also set BIT 0 (Transmit AIS-P Enable) to 1 to configure the Receive STM-0 TOH Processor
block to automatically transmit the AIS-P indicator, in response to this defect condition.
BIT 4 - Transmit Path AIS upon declaration of the Signal Degrade (SD) defect
This READ/WRITE bit-field is used to configure the Receive STM-0 TOH Processor block to automatically transmit a
Path AIS (AIS-P) Indicator via the downstream traffic (e.g., towards the Receive STM-0 POH Processor block) anytime
(and for the duration that) it declares the SD defect condition.
