Evolutions in communication systems

Abstract

Direct interaction between user and data processing system leads to rapidly increasing terminal periphery and information flow between system and terminals. Thus communications facilities become more and more a necessary part of interactive and teleprocessing systems. While the evolution of data processing technologies favours distributed processing at intelligent terminals, this very same trend also stimulates more sophisticated interaction with host CPU's, shifting access rates and call durations. This leads to increased demands on transmission networks. They undergo a multifacet proliferation towards digitalization and towards additional network functions by incorporation of stored program control. As a result data processing and telecommunications become more interwoven and the question of integrated systems gains much thrust from a user point of view.
