ABSTRACT:
An arrangement for connecting a personal computer (1) to a telephone network (2) via a digital exchange, in particular a private exchange (13), and via a telephone set (3) or subscriber terminal suitable for processing telephone signalling and enabling digital voice and data signals to be transferred simultaneously, the telephone set or subscriber terminal being controlled by an internal processor (14) of a controlling logic circuit (9) and including a data transmission (4B) for connection to a computer apparatus such as a computer. The coupler (4) is integrated in the telephone set and is connected to the controlling logic circuit (9) of the telephone set, which diverts the telephone signalling transmitted to the controlling logic circuit of the telephone towards an external access (1A1 or 1A2) to the bus of the personal computer, and which selectively replaces the telephone signalling which the telephone would normally transmit to the exchange by corresponding signalling produced by the personal computer.
