Circuit arrangement for a party line system (connection transfer device)

摘要

The invention relates to a circuit arrangement for a telecommunication system, particularly a business telephone system, with subscriber terminals which can be connected to party lines and which can be in each case controlled by a separate central processor. The circuit arrangement exhibits a connection transfer device (ANE) having in each case a dialling-system interface (WSS) and a party-line interface (GLS), the dialling-system interface (WSS) exhibiting traffic-direction-oriented DC-isolated line terminals (Fan, Fab) and signal terminals (E, M), whilst the party-line interface (GLS) contains common line terminals provided for voice and signal transmission. Such circuit arrangements are used in business telephone systems with party-line systems. <IMAGE>
