A Proposal for the Interworking of Preassignment Satellite and Terrestrial Systems with Demand-Assignment Satellite Systems in Interregional Telecommunication Networks

A proposal is presented for the interworking of preassignment and demand-assignment communication systems in future worldwide telephone networks. Considering the current and future worldwide traffic volume, the possible communication systems, especially the possible multiple-access systems, are compared. As a result, restoring the existing preassigned network by a time-division multiple-access system with demand-assigned channels appears most suitable for handling the Atlantic region traffic in 1975. The proposed interworking of the different systems will be explained with the aid of a simple network model.
