3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC DATA SHEET
2.2.7.3.2.4
The user can configure the Transmit STS-3c POH Processor block to automatically transmit the RDI-P
indicator, in response to the corresponding Receive STS-3c POH Processor block declaring the LOP-P
condition, by executing the following steps.
STEP 1 – Write the appropriate value into Bits 7 through 5 (LOP-P RDI-P Code[2:0]) within the
“Transmit STS-3c Path – RDI-P Control Register – Byte 0”; as illustrated below.
Transmit STS-3c Path – RDI-P Control Register – Byte 0 (Address = 0x19CB)
By writing this particular value into these three bit-fields, the user is specifying the value that the Transmit
STS-3c POH Processor block will set the RDI-P bit-fields (in the G1 byte, within the “outbound” STS-3c data-
stream) whenever the corresponding Receive STS-3c POH Processor block declares the LOP-P condition.
STEP 2 – Set Bit 4 (Transmit RDI-P upon LOP-P) within the “Transmit STS-3c Path – RDI-P Control
Register – Byte 0” to “1”; as illustrated below.
Transmit STS-3c Path – RDI-P Control Register – Byte 0 (Address = 0x19CB)
This step configures the Transmit STS-3c POH Processor block to automatically transmit the RDI-P indicator
(per the values written into Bits 3 through 1, within this register); anytime the corresponding “Receive STS-3c
POH Processor” block declares the “LOP-P” condition.
2.2.7.3.2.5
The user can configure the Transmit STS-3c POH Processor block to automatically transmit the RDI-P
indicator, in response to the corresponding Receive STS-3c POH Processor declaring the AIS-P condition, by
executing the following steps.
