An installation for connection of cordless telephones to a subscriber's exchange (1) thus to create a cordless telephone system comprises stationary base stations (2a-5b) which are wire-connected to the exchange (1), and portable handsets (10-13). The base stations (2a-5b) and the handsets (10-13) consist of short-range radio transmitters and receivers. The cordless telephone system comprises an interconnection unit (14) which is in wire communication with the exchange (1) and which is arranged to detect a calling signal in the exchange (1) and to transfer said signal to a control unit (15). The latter cooperates with the base stations (2a-5b) and orders the latter to search for the handset (10-13) for which the call is intended. The base station (2a-5b) that finds the handset (10-13) in question is arranged to inform the control unit (15) accordingly and to simultaneously emit a cordless call to the handset (10-13). When an answer is received, communication with the subscriber's exchange (1) is sought and the exchange is arranged to then establish call communication between the calling subscriber and said base station (2a-5b). |
