4.6 App 6: MSE-1482 Path Cross-Connect Functionality
The Z-Series MSE-1482 line card provides cross-connect capability at the STS-1, STS-3c, STS-12c, and
STS-48c levels. The system provides Path level connectivity so that subtending equipment with Path level
protection such as UPSR or SNCP can operate over the MSE-1482 line card. In this configuration the
MSE-1482 line card does not transport the line overhead such as the Data Communication Channel (DCC).
The line card supports a 100 Mbps Optical Supervisory Channel (OSC) that provides the DCN connectivity
to subtending SONET/SDH network elements.
The MSE-1482 line card supports UPSR/SNCP Path protection and unidirectional 1+1 Line protection. The
diagrams below show protection, the Path level application, and capabilities of the MSE-1482 line card. In
Path cross-connect mode, the interface is transported as a cross-connect at the STS-1 level signal or STS-Nc
as provisioned.
