28-CHANNEL DS1/E1 FRAMER/LIU WITH DS3 MUX & VT-MAPPER - SONET APPLICATIONS
REV. P1.0.6
BIT [7:6] - Unused
BIT 5 - Transmit DS1/E1 AIS (via Downstream T1/E1s) upon declaration of the LOS (Loss of Signal) defect
condition
This READ/WRITE bit-field is used to configure each of the 28 Egress Direction Transmit DS1/E1 Framer blocks to
automatically transmit the DS1/E1 AIS Indicator via the downstream DS1/E1 signals, anytime (and for the duration that)
the Receive STS-1/STS-3 TOH Processor block declares the LOS defect condition.3
`
0 - Does not configure all 28 of the Egress Direction Transmit DS1/E1 Framer blocks to automatically transmit the
DS1/E1 AIS Indicator via the downstream DS1/E1 signal, anytime the Receive STS-1/STS-3 TOH Processor block
declares the LOS defect condition.
`
1 - Configures all 28 of the Egress Direction Transmit DS1/E1 Framer blocks to automatically transmit the DS1/E1
AIS Indicator via the downstream DS1/E1 signals, anytime (and for the duration that) the Receive STS-1/STS-3 TOH
Processor block declares the LOS defect condition.
BIT 4 - Transmit DS1/E1 AIS (via Downstream T1/E1s) upon declaration of the LOF (Loss of Frame) defect
condition
This READ/WRITE bit-field is used to configure each of the 28 Egress Direction Transmit DS1/E1 Framer blocks to
automatically transmit the DS1/E1 AIS Indicator via the downstream DS1/E1 signals, anytime (and for the duration that)
the Receive STS-1/STS-3 TOH Processor block declares the LOF defect condition.
`
0 - Does not configure all 28 of the Egress Direction Transmit DS1/E1 Framer blocks to automatically transmit the
DS1/E1 AIS Indicator via the downstream DS1/E1 signals, anytime the Receive STS-1/STS-3 TOH Processor block
declares the LOF defect condition.
`

AIS Indicator via the downstream DS1/E1 signals, anytime (and for the duration that) the Receive STS-1/STS-3 TOH
Processor block declares the LOF defect condition.
BIT 3 - Transmit DS1/E1 AIS (via Downstream T1/E1s) upon declaration of the SD (Signal Degrade) defect condition
This READ/WRITE bit-field is used to configure each of the 28 Egress Direction Transmit DS1/E1 Framer blocks to
automatically transmit the DS1/E1 AIS Indicator via the downstream DS1/E1 signals, anytime (and for the duration that)
the Receive STS-1/STS-3 TOH Processor block declares the SD defect condition.
`
0 - Does not configure all 28 of the Egress Direction Transmit DS1/E1 Framer blocks to automatically transmit the
DS1/E1 AIS Indicator via the downstream DS1/E1 signals, anytime the Receive STS-1/STS-3 TOH Processor block
declares the SD defect condition.
`
1 - Configures all 28 of the Egress Direction Transmit DS1/E1 Framer blocks to automatically transmit the DS1/E1
AIS Indicator via the downstream DS1/E1 signals, anytime (and for the duration that) the Receive STS-1/STS-3 TOH
Processor block declares the SD defect condition.
BIT 2 - Transmit DS1/E1 AIS (via Downstream T1/E1s) upon declaration of the Signal Failure (SF) defect condition
This READ/WRITE bit-field is used to configure each of the 28 Egress Direction Transmit DS1/E1 Framer blocks to
automatically transmit the DS1/E1 AIS Indicator via the downstream DS1/E1 signal, anytime (and for the duration that)
the Receive STS-1/STS-3 TOH Processor block declares the SF defect condition.
`
0 - Does not configures all 28 of the Egress Direction Transmit DS1/E1 Framer blocks to automatically transmit the
DS1/E1 AIS Indicator via the downstream DS1/E1 signal, anytime the Receive STS-1/STS-3 TOH Processor block
declares the SF defect condition.
