ABSTRACT:
A communications system is disclosed for switching connected communications terminal devices includes a central module including a processor-controlled base unit and a supplementary unit as well as at least one peripheral subscriber module and up to four subscriber transmission units. The peripheral subscriber modules and the subscriber transmission units allow the connection of communications terminal devices or, alternatively, the connection to public communications networks is possible. A switching element implemented in the base unit supports an ISDN-oriented interface to which up to four particularly low-cost subscriber transmission units may be connected. A small or mid-sized communications system having a modular construction can thereby be designed in such a fashion as to be expandable at the lowest expense while allowing flexibility of configuration.
