CALL SET-UP SERVER

摘要

A communication system is provided which permits the transfer of broadband multimedia data through a network. The communication 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 used for call handling. The central part sets up a call between parties in the system and operates independently from the access part and the user part, enabling a new access part to be added without affecting the existing central part.
