Abstract :
The critical issues in multivendor environments and operation systems of telecommunication networks essential to speeding up the handling of service orders and service restoration after failures are discussed. To overcome these problems as the software backlog grows, the authors propose the application of a telecommunications management network (TMN) architecture together with an object-oriented network resource (ONR) model. The second phase of the synchronous digital hierarchy (SDH) network management system, which is based on the TMN architecture and ONR model, is examined.<>
