Advanced telephone services in local area networks

Abstract

Local Area Networks (LANs) able to support both data and digitized voice are under development in several laboratories. Up to day the interest of the researchers was focused on the choice of the physical media to be used in the LAN, on the access protocols, and on the network topology.In this paper another aspect of the problem of the integration of data and voice on the same LAN is investigated.More precisely some advanced telephone services, that can be implemented on LAN3 are presented. In particular the Conference Service, here named Multiple Internal Call, is deeply investigated. Other services, such as the Call Queue or the By-Pass, that can be considered as typical services of the ofice of the near future are described.
