The management modelling of access networks

The management of access networks raises questions about the traditional approach to the creation of management models because access networks are geographically dispersed and may be implemented using a number of other TMN network elements, and because their Q-interface may be remote from their traffic or service interfaces. The related problems can be solved by using a model based on a two dimensional functional architecture, with new classes to supplement the one-dimensional, bottom-up classes of the CCITT (ITU) Recommendation M.3100. This creates a richer structure for management modelling which no longer constrains possible implementations
