A communication system (KS) comprises a switching unit (SWU) for communication line switching, with a coupling field and a central control system, at least one centralized server (S1 ... SN) which provides data and programmes for performance features, and peripheral modules (SLMA, SLMB) which act as interfaces to subscriber terminals. Special terminals (DDB) with actuating means, optical display means, at least one loudspeaker and at least one handset are connected to special peripheral modules (SLMT) which are connected to the switching unit (SWU) and linked to each other via data paths (D), and are incorporated as integral components of the communication system (KS), conformably to the system, through control procedures (BS, BT), transmission technique procedures (VT) and data bank procedures (DB). The invention allows digitally based office communication and provides corresponding performance characteristics for special applications such as brokerage installations. |
