28-CHANNEL DS1/E1 FRAMER/LIU WITH DS3 MUX & VT-MAPPER - SONET APPLICATIONS
BIT6 - Unused
BIT 5 - Transmit Line - Remote Defect Indicator
This READ/WRITE bit-field is used to (by software control) force the Transmit STS-1/STS-3 TOH Processor block to
generate and transmit the RDI-L indicator to the remote terminal equipment.
`
0 - Does not configure the Transmit STS-1/STS-3 TOH Processor block to generate and transmit the RDI-L indicator.
`
1 - Configures the Transmit STS-1/STS-3 TOH Processor block to generate and transmit the RDI-L indicator.
In this case, the Transmit STS-1/STS-3 TOH Processor block will force bits 6, 7 and 8 (of the K2 byte) to the value 1,
1, 0.
N
OTE
:
This bit-field is ignored if the Transmit STS-1/STS-3 TOH Processor block is currently transmitting the Line AIS
(AIS-L) indicator or LOS pattern.
BIT 4 - Transmit Line - AIS Indicator
This READ/WRITE bit-field is used to (by software control) force the Transmit STS-1/STS-3 TOH Processor block to
generate and transmit the AIS-L indicator to the remote terminal equipment.
`
0 - Does not configure the Transmit STS-1/STS-3 TOH Processor block to generate and transmit the AIS-L indicator.
`
1 - Configures the Transmit STS-1/STS-3 TOH Processor block to generate and transmit the AIS-L indicator.
In this case, the Transmit STS-1/STS-3 TOH Processor block will force all bits (within the outbound STS-1 or STS-3
frame) with the exception of the Section Overhead Bytes to an All Ones pattern.
N
OTE
:
This bit-field is ignored if the Transmit STS-1/STS-3 TOH Processor block is transmitting the LOS pattern.
BIT 3 - Transmit LOS Pattern
This READ/WRITE bit-field is used to (by software control) force the Transmit STS-1/STS-3 TOH Processor block to
transmit the LOS (Loss of Signal) pattern to the remote terminal equipment.
`
0 - Does not configure the Transmit STS-1/STS-3 TOH Processor block to generate and transmit the LOS pattern.
`
1 - Configures the Transmit STS-1/STS-3 TOH Processor block to transmit the LOS pattern. In this case, the
Transmit STS-1/STS-3 TOH Processor block will force all bytes (within the outbound SONET frame) to an All Zeros
pattern.
BIT 2 - Scramble Enable
This READ/WRITE bit-field is used to either enable or disable the Scrambler, within the Transmit STS-1/STS-3 TOH
Processor block circuitry.
`
0 - Disables the Scrambler.
`
1 - Enables the Scrambler.
BIT 1 - Transmit B2 Byte Error Insert Enable
This READ/WRITE bit-field is used to configure the Transmit STS-1/STS-3 TOH Processor block to insert errors into
the outbound B2 bytes, per the contents within the Transmit STS-1/STS-3 Transport - Transmit B2 Byte Error Mask
Register.
`
0 - Configures the Transmit STS-1/STS-3 TOH Processor block to NOT insert errors into the B2 bytes, within the
outbound STS-1 or STS-3 signal.
`
1 - Configures the Transmit STS-1/STS-3 TOH Processor block to insert into the B2 bytes (per the contents within
the Transmit B2 Byte Error Mask Register).
BIT 0 - Transmit A1A2 Byte Error Insert Enable
This READ/WRITE bit-field is used to configure the Transmit STS-1/STS-3 TOH Processor block to insert errors into
the outbound A1 and A2 bytes, within the outbound STS-1 or STS-3 data-stream.
`
0 - Configures the Transmit STS-1/STS-3 TOH Processor block to NOT insert errors into the A1 and A2 bytes, within
the outbound STS-1 or STS-3 Data-stream.
`
1 - Configures the Transmit STS-1/STS-3 TOH Processor block to insert errors into the A1 and A2 bytes, within the
outbound STS-1 or STS-3 Data-stream.
