Rev.1.2.0.
2.3.1.4.3
The user can configure the Transmit STS-3 TOH Processor block to automatically transmit the RDI-L
indicator to the remote LTE whenever (and for the duration that) the corresponding Receive STS-3 TOH
Processor block declares the AIS-L defect condition.
Figure 85 presents an illustration of the Transmit STS-3 TOH Processor block transmitting the RDI-L
indicator, to the remote LTE, whenever the corresponding Receive STS-3 TOH Processor block declares the
AIS-L defect condition.

transmitting the RDI-L indicator, to the remote LTE whenever the corresponding Receive STS-3 TOH
Processor block declares the AIS-L defect condition.
The user can implement this configuration by setting Bit 2 (Transmit RDI-L upon AIS-L) within the Transmit
STS-3 Transport – RDI-L Control Register, as depicted below.

2.3.1.4.4
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 AIS-L defect condition.
Note:
Figure 86 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
AIS-L 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 three Receive SONET POH Processor
blocks, in parallel, whenever it declares the AIS-L defect condition.
