3-CHANNEL DS3/E3/STS-1 TO STS-3/STM-1 MAPPER IC DATA SHEET
Transmit STS-3 Transport – RDI-L Control Register (Address = 0x1933)
2.3.1.3.6.4
The user can configure the Receive STS-3 TOH Processor block to automatically transmit the AIS-P
indicator, in the down-stream direction (towards the corresponding Receive STS-3c POH Processor block)
whenever (and for the duration that) it declares the LOF defect condition.
Note:
Figure 83 presents an illustration of the Receive STS-3 TOH Processor block transmitting the AIS-P indicator,
in the down-stream direction (towards the Receive STS-3c POH Processor block) whenever it declares the
LOF defect condition.

If the XRT94L33 is configured to operate in either the “1-Channel STS-3 ATM UNI/PPP” Mode, then the Receive
STS-3 TOH Processor block will transmit the AIS-P indicator to all four Receive SONET POH Processor blocks,
in parallel, whenever it declares the LOF defect condition.
