International ClassH04Q 011/04AbstractA communication system is provided which permits the transfer of broadband multimedia data through a network. The system includes network terminals, a transmission backbone, and a call set-up server. The call set-up server controls call handling and connection handling. The call set-up server includes an access part, a user part, and a central part. The central part sets up a call between parties in the system and operates independently from the access part and the user part. The call set-up server also includes a service pointer which permits supplementary services to be added, removed or modified and permits access parts to be added or modified, without affecting already existing services and access parts.Other References
