scope:

The present document provides a management information model [12] which covers the management aspects of the "routing and digit analysis" function in an exchange. The scope is further limited to the exchange aspects of circuit switched networks. This model is restricted to the Operations Systems (OSs) to Network Element (Q3) interface (see ITU-T Recommendation M.3010 [7]). The information to be managed is limited to the signalling systems Digital Subscriber Signalling System No. 1 (DSS1) , Signalling System CCITT No.5 (C5), Signalling System Number 7 (SS No.7) - ISDN User Part (ISUP) only) and Regional Signalling 2 (R2). (SS No.7 with Telephone User Part (TUP) level 4 is not considered.) The information for routing purpose, which needs to be maintained by the manager, depends on the signalling systems used by the exchange. This information model can be applied for exchanges with the known standardized signalling systems DSS 1, SS No. 7, R2, C5. Because of the existence of different signalling systems, not all attributes and objects will be applicable for all exchanges. Information about applicability can be found in the object classes behaviour.
