4.5 App 5: MSE-1482 Transparent Line Functionality
In this application, the Cyan Z33 shelf or the Z77 shelf contains a pair of MSE-1482 line cards. Transparent
Line service provides transparent SONET/SDH transport for OC-3/STM-1, OC-12/STM-4,
OC-48/STM-16, and GbE client interfaces (downlinks) while preserving section and line overhead. This
feature allows service providers to aggregate multiple services by efficiently mapping and conserving
wavelength capacity.
The MSE-1482 line card provides line transparency for Line overhead including protection bytes and Data
Communications Channel (DCC). In Transparent Line SONET-over-SONET transport mode, STS
cross-connections are not allowed within the port signal.
The next two diagrams show examples of Transparent Line capabilities, functionality, and route diversity of
the MSE-1482 line card.
