Communication system for multiservice terminals in a local area network.

A local area network, in the next network-specific services in addition having narrowband or telephone services (SB, FE) having communications terminals (KE) ( "Multimedia" -Kommunikationsendeinrichtungen) are provided via a network matching device (APE) to the subscriber line interface (TAS) of a communication system (KA) with narrowband or telephone communications functions (SB, FE) connected. By inserting a with subscriber equipment (TLE), an adaptation unit (AE) and an access device (LANZ) on the local area network (LAN) equipped interworking unit (APE) remain the functions of both networks (narrowband or telephone network and local area network LAN) largely unchanged and with minimal additional effort a maximum modularity and flexibility in the establishment and expansion of communication systems with "Multimedia" -Kommunikationsendeinrichtungen is achieved.
