This Recommendation provides an overview of the functions, procedures and entities for managing the Signalling System No. 7 (SS No. 7) network. The requirements upon SS No. 7 management are summarized, namely: a) to provide a Telecommunication Management Network (TMN) interface to the network operator, b) to interwork with other TMN parts (e. g. Synchronous Digital Hierarchy (SDH) to enable the provision of a unified approach to managing the whole telecommunications network, and c) to extend where necessary the internal management functions of SS No. 7, so as to amalgamate them with TMN. OMAP should also provide consistency between the SS No. 7 levels (layers) and across the SS No. 7 network. The abstract model of SS No. 7 management is defined, and its relationship with the SS No. 7 levels is explained. The management functions additional to those of OSI (e. g. functions for auditing routing, functions for testing implementations of levels of SS No. 7 from an in-service node, etc.) are explained. Compatibility is considered, and an overview of the OMAP Recommendations is given.
