Rev.1.2.0.
Receive STS-3 Transport Status Register – Byte 0 (Address = 0x1107)
Setting Bit 2 (Change of LOF Defect Condition Interrupt Status) within the Receive STS-3 Transport Interrupt
Status Register – Byte 0 to “1” as depicted below.
Receive STS-3 Transport Interrupt Status Register – Byte 0 (Address = 0x110B)
2.3.1.3.6.3
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 LOF defect condition.
Figure 82 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
LOF defect condition.
Figure 82 Illustration of the Transmit STS-3 TOH Processor block (within a given XRT94L33)
transmitting the RDI-L indicator, to the remote LTE whenever the corresponding Receive STS-3 TOH
Processor block declares the LOF defect condition.
The user can implement this configuration by setting Bit 1 (Transmit RDI-L upon LOF) within the Transmit
STS-3 Transport – RDI-L Control Register, as depicted below.
