電話装置の市外通話禁止回路。 A base station connection device that connects to a wired telephone line that enables telephone calls to be made by dialing a telephone via a private branch exchange, and a handy phone connected to this connection device by a wireless link. In a cordless telephone device having a plurality of channels, a normal dialing signal, a 0-dial outgoing prohibition signal, and an incoming-only called signal are accepted into the port section, and the 0-dial outgoing prohibition signal is received from the port section except when the above-mentioned 0-dial outgoing prohibition signal is received. “0” or “1”
”; a dial pulse generator that sends out a dial pulse based on the logical output “1”; and a noise removal circuit that accepts the dial pulse. A long-distance call prohibition circuit for a cordless telephone device, characterized in that the circuit is connected to a telephone line and all calls to telephone numbers starting from 0 from the handy telephone device are disabled.
