PURPOSE:To realize the call to the service subscriber through the collation between the register number of the service subscriber and the number of the originating side subscriber. CONSTITUTION:The terminal on the line link of the subscriber receiving the specific subscriber incoming service is switched to the specific subscriber incoming device by the service request action. And now subscriber SUB.B gives a call with reception of the number of subscriber SUB.A giving dialing at originating register OR after the service is requested by the service subscrober.Thus the received number is connected onto the line link of main frame LINK by the exchange action. At this moment the terminal on the line link is switched to specific subscriber incoming device SPE. In this respect, the registered secret number is collated with the dialed number of SUB.B. And the line is connected to SUB.A only when the coincidence is obtained through the collation.
