ONS 15454 SDH Release 3.4 contains an MS-SPRing Provisioning Wizard,

accessed through the Provisioning tab in the network view. The wizard allows you

to easily create, edit, and delete MS-SPRings at the network level, using the CTC

interface. The wizard not only reduces common errors in ring creation, it also

helps you to create, edt, and delete MS-SPRings much faster than it takes to

perform the same operations on a node-by-node basis.
