This paper describes the roles and benefits of an ATM transport network composed of ATM transport systems, such as ATM cross-connect systems and / or ATM add-drop multiplexers. The ATM transport network is an economical way of providing the ATM public network and a virtual path service for enterprise users. This paper exemplifies the effectiveness of a VP grooming function in the ATM transport system by comparing it to the network costs with direct fiber connection, an alternative to VP grooming. Main and junction module architecture for the ATM cross-connect system is proposed to realize an economical network that supports small to large traffic. For implementing a large-scale cross-connect switch, a cell congestion control method that employs re-arrangement control and a concentration network is proposed. Implementation of multiple service classes and VP protection switching in the ATM cross-connect system are mentioned. We also describe an SDH signal transmission method based on ATM cells, that offers a cost effective and reliable transport network.
