Abstract: PURPOSE:To prevent a private telephone set from being used with out permissim by previously setting and registering a password in an exchange and dialing said number after off-hook. CONSTITUTION:When a telephone set TEL is hooked off to lead a subscriber circuit LC 3 to transmit its looped state to a central control unit CP 7, it detects the transmission, and reads a subscriber's class work stored in the CP 7 from the subscriber's terminal number. Next, the CP 7 checks whether the transmission is from a recognized and registered telephone set, judging from a subscriber type registered in the subscriber's class word. If so, the CP 7 connects the LC 3 to a dial signal receiver RECA 5 through a channel switch NM1. Immediately the RECA transmits a password request sound to a telephone set TEL 2. Then the received dial signal is compared with a password previously recorded in the subscriber's class word. If the password is received correctly, the CP 7 swaps the LC 3 to on RECB 6 through the NW 1.
