Abstract

PURPOSE:To perform a three-party telephone call efficiently without disturbing and interruping a call when the 3rd party requests a call, by making interrupting multiple connection under the control of a centralized control station. CONSTITUTION:While a subscriber 1 has a telephone call with another subscriber with a train 3, a call memo service request signal from the subscriber 1 is branched by a low-pass filter 14, and received by a modem 10, and this signal is sent out to a controller 12. After detecting this request signal, the controller 12 sends it to a common processor 20. The processor 20 adds the telephone number of the subscriber 1 to the input signal and then sends the resulting signal to a centralized control station 25 through a data signal transfer device 22. The centraized control station 25 analyzes this signal to judge the subscriber 1 and a voice storage device 30 should be connected mutually. A central processor 28 actuates a connection controller 26 and accesses a station 6 to be controlled through a train 7, thereby making connection with a subscriber circuit switching device 2. The switching device 2 is connected to a multiple connection device 21, from which a connection end signal is returned to the centralized control station 25.
