SONET/SDH TRIBUTARY UNIT PAYLOAD PROCESSOR FOR 622 MBIT/S
INTERFACES

APPLICATION EXAMPLES
The TUPP+622 can be used in SONET/SDH network elements including
switches, terminal multiplexers, and add-drop multiplexers. In such applications,
the TUPP+622 performs VT (TU) pointer processing to align the virtual tributaries
to facilitate cross-connecting and SONET ring closure. The TUPP+622 also
performs performance monitoring of any legal mix of tributaries to implement
intermediate performance monitoring. The TUPP+622 is well suited to process
data from one STS-12 (STM-4), four STS-3’s (STM-1’s) or one quarter of an
STS-48 (STM-16).
5.1 STS-12 (STM-4) AGGREGATE INTERFACE
Figure 1 shows how the TUPP+622 is used to implement a single 77.76 MHz
STS-12 (STM-4) aggregate interface. In this application, the PM5313 SPECTRA-
622 performs SONET/SDH section, line and path termination and the PM5363
TUPP+622 performs tributary pointer processing and performance monitoring.
