Abstract

PURPOSE:To prevent useless outgoing due to illegal use and mischief by inhibiting a calling signal from being sent out even with the handset off the hook when an originating regulation code is input. CONSTITUTION:Hook signal control circuit 7 is so constituted that once a specific code regulating originating operation is input from code input circuit 8, an off-hook signal from hook signal generating circuit 3 will not be applied to talking circuit control circuit 4. To release the originating regulation, the previously-input originating regulation code is input again.
