Transmission and Multiplexing (TM); Management of Synchronous Digital Hierarchy (SDH) Transmission Equipment; Fault Management and Performance Monitoring; Functional Description (V1.1.1)
The present document specifies the functional requirements for fault management and performance monitoring aspects of SDH equipments. The Telecommunications Management Network (TMN) provides management functions which cover the planning@ installation@ operations@ administration@ maintenance and provisioning of telecommunications networks and services. ITU-T Recommendation M.3010 [1] proposes five management functional areas identified as follows: - Fault management; - Performance management; - Configuration management; - Security management; - Accounting management. The present document provides guidance and supporting information for the functional specification for the first two of these management areas. The TMN functionality is realized by means of processes in Equipment Management Function (EMF) in Network Elements (NE)@ Element Management Systems (EMS) and Network Management Systems (NMS) or Operation Systems (OS). The present document fully specifies the EMF functionalities. NMS/OS functionalities are described only if needed for clarification.
