BIT [7:0] - Transmit K2 Byte Value
If the appropriate K1K2 Insert Method is selected, then these READ/WRITE bit-fields will are used to specify the
contents of the K2 byte, within the outbound STS-1/STS-3 signal.
N
OTE
:
If BIT 1 (K1K2 Insert Method) within the Transmit STS-1/STS-3 Transport - SONET Transmit Control Register -
Byte 1 (Address Location= 0x0702) is set to 1, then the Transmit STS-1/STS-3 TOH Processor block will load
the contents of this register into the K2 byte-field, within each outbound STS-1 or STS-3 frame. These register
bits are ignored if BIT 1 (K1K2 Insert Method) is set to 0.
BIT [7:0] - Transmit K1 Byte Value
If the appropriate K1K2 Insert Method is selected, then these READ/WRITE bit-fields will are used to specify the
contents of the K1 byte, within the outbound STS-1/STS-3 signal.
N
OTE
:
If BIT 1 (K1K2 Insert Method) within the Transmit STS-1/STS-3 Transport - SONET Transmit Control Register -
Byte 1 (Address Location= 0x0702) is set to 1, then the Transmit STS-1/STS-3 TOH Processor block will load
the contents of this register into the K1 byte-field, within each outbound STS-1 or STS-3 frame. These register
bits are ignored if BIT 1 (K1K2 Insert Method) is set to 0.
BIT [7:4] - Unused
BIT 3 - External Transmit Line Remote Defect Indicator (RDI-L) Enable
This READ/WRITE bit-field is used to externally insert the value for bits 6, 7 and 8 (of the K2 byte) into the outbound
STS-1 or STS-3 Data stream. If the user enables this feature, then the user can enable or disable the insertion of the
RDI-L indicator, via the TxPOH_n input pin.
0 - Disables this feature.
1 - Enables this feature.
BIT 2 - Transmit Line Remote Defect Indicator (RDI-L) upon Detection of AIS-L
