Abstract

PURPOSE:To realize permission or regulation for the incoming in response to the request from the receiver of the incoming by providing the incoming regulation register memory. CONSTITUTION:When transmitter 1 dials the telephone number of receiver 4, control unit 3 selects circuit 6 connected to terminating station 5 to connect transmitter 1 to outgoing trunk 7. Then the incoming telephone number and the transmitter's telephone number are sent out to signal receiver 10 at station 5 from signal transmtter 9. At station 5 a collation is given between the incoming permission telephone number against receiver 4 memorized in memory device 12 and the telephone number of transmitter 1 through control unit 11. And in case the coincidence is obtained, the control is given between receiver 4 and incoming trunk 13 corresponding to circuit 6. While in case no coincidence is obtained, a connection is given between trunk 13 and trunk 15 displaying the regulation state of the incoming in order to display the incoming regulation state to transmitter 1.
