Abstract :
A future B-ISDN (broadband integrated services digital network) will need flexibility for various service requirements and traffic enlargement and fluctuation. The authors define the layer functions for a model of network node functions and for its interlayer interfaces. They also provide a generic example of a node configuration. The necessity of introducing a three-layered transmission system and control and management layers corresponding to each layer for a flexible communications network is presented. The idea of applying self-routing switches to switching equipment in the user layer and cross-connect equipment in the logical layer is also presented
