Abstract

Abstract A scaleable PBX (Private Branch exchange) is provided for use in a powerful, facilities-based, broadband communications system that guarantees voice, data and video communication reliability and security to users for an multimedia system including integrated telephone, television and data network. The scaleable PBX includes one or more broadband gateways. Each broadband gateway may be provided on a slot card (i.e., broadband gateway card) compatible with servers and personal computers (PC). One or more slot cards may be include in a server to provide PBX feature/function capability to a broadband communication system. The server based broadband gateway PBX is scaleable for any size company or facility using, for example, one or more network servers. Alternatively, the broadband gateway card may be installed in a PC and provide a low cost small business or home PBX system.
