Abstract

The paper firstly provides an introduction to the broadband call control demonstrator platform developed at BT Laboratories. It describes the basic connection level functionality used to give point-to-point and point-to-multipoint call demonstrations. It then describes the introduction of a Digital Audio-Visual Council (DAVIC)-conformant session control capability and how this is used as the basis of a more comprehensive demonstration. The paper also examines how future networking concepts such as object orientation and distributed processing environments are being introduced, in particular the interworking between DAVIC and Telecommunications Information Network Architecture Consortium (TINA-C) approaches. Finally, some of the evolutionary aspects of the broadband call control demonstrator platform are introduced.
