Synchronous Digital Hierarchy (SDH) - Configuration of Linear Multiplex-Section Protection for the Network Element View Series G: Transmission Systems and Media Digital Systems and Networks Digital Terminal Equipments - Operations Administration and Maint
Recommendation G.774.3 defines an information model for management of fixed linear Multiplex Section Protection (MSP) groups. This Recommendation defines the object model that allows to configure flexible linear MSP groups in accordance with the requirements described in Recommendation G.784. This model can be used to establish, modify and remove MSP groups for Network Elements that require external provisioning to configure their protection switching schemes. The protection switching scheme of an SDH network element is usually set up autonomously by the network element according to its make-up and mode of operation. When this is not possible, the information model defined by this Recommendation will be used. Postconfiguration control of the protection function is carried out by means of the object model defined in Recommendation G.774.3.
