APPLICATION EXAMPLE
The PM5361 TUPP is typically used as part of a SONET/SDH tributary cross-
connect. TUPPs can be used to transfer the payloads of incoming tributaries into
outgoing tributaries that are aligned to facilitate switching. A typical example is
shown below.
This example shows the tributaries extracted from an STS-1 or AU3 path
terminating device, such as the PM5344 SPTX SONET/SDH Path Terminating
Transceiver, being routed through TUPPs so as to be aligned for cross-
connection using the PM5371 TUDX SONET/SDH Tributary Unit Cross-Connect.
The TUPP (and SPTX) can be bypassed by switching through whole STS-1s or
AU3s that are output by the PM5323 TSPP Triple SONET/SDH Payload
Processor. Note that in this application example, the TUPPs are operating in
locked output mode (i.e. their OJ1EN bits are low) to allow convenient interfacing
to the TUDX chip.
