SONET/SDH Path Support

The 7705 SAR supports a subset of the standards-based channel mapping options. Table: SONET/SDH Paths Supported on the 7705 SAR  shows path support on the 7705 SAR.

Note:

When configuring a port for SDH framing, the 7705 SAR CLI uses SONET STS-n frame conventions. That is, SONET command syntax and nomenclature is used to configure both a SONET port and an SDH port.

The 7705 SAR CLI always uses the SONET VT frame convention. For example, the same SONET CLI syntax and nomenclature would be used to configure both a VT1.5 and a VC11. The framing {sonet | sdh} command determines whether VTs or VCs are being configured. Use the show>port-tree port-id command to display the SONET/SDH path containers.
