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.
