Integrated text-communication services digital networks
Abstract
Circuit and packet switched facilities as well as distributed information processing units handling new text communication services are part of future integrated services digital networks. The functional integration of text communicaton procedures with the digital network is discussed. Unified handling of batch and interactive text communications is proposed. The use of standardized protocols at both transport and user service levels is suggested. The implementation of transport service layered functions into actual hierarchical communication levels is examined. It is shown possible to define standardized protocols common to both circuit switched and packet switched operating facilities. The text communication functions pertaining to session and presentation tasks are described. A session protocol common to both batch and interactive services is envisaged and real as well as virtual presentation services are considered.
