Rev.1.2.0.
STEP 2 – Set Bit 4 (Transmit RDI-P upon LCD-P) within the “Transmit STS-3c Path – RDI-P Control
Registers – Byte 2” to “1”, as illustrated below.
Transmit STS-3c Path – RDI-P Control Register – Byte 2 (Address = 0x19C9)
2.2.7.3.2.8
The user can configure the Transmit STS-3c POH Processor block to transmit the RDI-P (per software
command) by executing the following steps.
STEP 1 – Write the value “[0, 1]” into Bits 3 and 4 (RDI-P Insertion Type[1:0]) within the “Transmit
STS-3c Path – SONET Control Register – Byte 0”, as depicted below.
Transmit STS-3c Path – SONET Control Register – Byte 0 (Address = 0x1983)
This step configures the “Transmit STS-3c POH Processor” block to automatically read out the contents of
bits 3 through 1 (of the “Transmit STS-3c Path – G1 Byte Value” register); and write the value of these bits
into bits 5 through 7 (of the G1 byte) within the “outbound” STS-3c SPE. The bit-format of the “Transmit STS-
3c Path – G1 Byte Value” register (with the appropriate bits “shaded”) is presented below.
Transmit STS-3c Path – Transmit G1 Byte Value Register (Address = 0x199F)
In this mode, the user can transmit an “un-erred” indicator by setting Bits 3 through 1 (within the Transmit
STS-3c Path – Transmit G1 Byte Value” register) to [0, 0, 0]. Conversely, the user can now transmit an
“erred” indicator by setting Bits 3 through 1 (within the “Transmit STS-3c Path – Transmit G1 Byte Value”
register) to some value other than [0, 0, 0].
