Summary

This Recommendation provides an information model for the Synchronous Digital Hierarchy (SDH) Network. This model describes the managed object classes and their properties for the configuration and post-configuration management of the protection switching function of SDH Multiplex Section (MS) Shared Protection Ring (SPR), as defined in ITU-T G.803 [12], ITU-T G.841 [15] and ITU‑T G.842 [16]. These objects are useful to describe information exchanged across interfaces defined in ITU-T M.3010 [3] Telecommunications Management Network (TMN) architecture for the configuration and post-configuration management of the protection function.
