Communication system for multi-service communication terminal equipment in local networks

A communication arrangement having communication terminal equipment that are connected to a local network, at least one of the communication terminal equipment having narrow band and telephone communication functions, comprising:

• a communication system that controls and influences narrow band and telephone communication functions and that has subscriber line interfaces;
• interworking unit connected between the local network and the communication system, said interworking unit being connected to the local network via an access apparatus and being connected to subscriber line interfaces of the communication system via subscriber equipment, a subscriber line interface being arranged between the interworking unit and the communication system for every communication terminal equipment of the local network that has narrow band and telephone communication functions;
• the interworking unit having a matching unit for matching signalling and message information communicated from a communication terminal equipment of the local networks or from the communication system for call control of narrow band and telephone communication connections to signalling procedures and message formats of the communication system and the local network, respectively;
• and
• the communication system being structured such that narrow band and telephone communication connections of the communication terminal equipment of the local network are switched to other communication terminal equipment of the local network and the communication system and are influenced for controlling performance features in the communication system.
