XRT94L33
Rev.1.2.0.
Receive STS-3 Transport Interrupt Status Register – Byte 0 (Address = 0x110B)
2.3.1.2.3
The user can configure the Transmit STS-3 TOH Processor block to automatically transmit the RDI-L
indicator whenever (and for the duration that) the corresponding Receive STS-3 TOH Processor block
declares the LOS defect condition.
Figure 79 presents an illustration of the Transmit STS-3 TOH Processor block transmitting the RDI-L indicator
(up-stream) towards the remote LTE whenever the corresponding Receive STS-3 TOH Processor block is
declaring the LOS defect condition.
Figure 79 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 is declaring the
LOS defect condition
The user can implement this configuration by setting Bit 0 (Transmit RDI-L upon LOS) within the “Transmit
STS-3 Transport – RDI-L Control Register, as depicted below.
