Adapting management of DX 200 switching system into TMN object model

The work for developing standards for TMN (Telecommunications Management Network) has reached a point where the overall principles have been defined and widely accepted. A digital exchange can be considered as network element (NE) in the TMN model. However, the distributed structure, the large amount of software and the wide variety of functionality that are characteristic of many digital exchanges mean that there is an exceptionally large amount of management information within a single NE. DX200 is a digital switching system with a wide variety of applications in public switched network as well as in mobile networks (GSM, NMT). The decentralized architecture DX200 system is based on loosely coupled microcomputers. The demands for modifications in the DX200 system indicated by the TMN object-oriented model are studied and possible solutions to fulfil the new requirements are described. Emphasis is put on studying how the existing management software could be utilized to minimize the amount of work needed to fulfil the requirements suggested by the TMN object-oriented model. The new software architecture must also be flexible enough to allow quick implementation of unknown object classes that are to be defined in international standardization bodies
