Abstract: Q3 interface adaptation technology is presented to implement the TMN-based network management on traditional telecommunication devices that can not be directly managed by TMN operation system for they have no Q3interface. Then the theory of Q3 interface adaptation technology is illustratedin details. On the basis of the theory and the analysis of the result of trials, an optimized architecture is designed for the implementation of adaptation technology. In the end, an ODP viewpoint is also applied to analyze the internal interface in the architecture to provide specific telecommunication devices with TMN-based network management interface.

Key words: TMN, interface adaptation, ODP
