を特徴とする電話機。 A selection signal sending circuit that captures the line and sends out a dialing signal for either a push button dial line or a DC impulse dial line, a dial tone detection circuit that detects a dial tone on the line, and dial information is input. Then, based on this, the selection signal sending circuit sends out a dial signal for the push button dial line, and if the dial tone detection circuit detects a dial tone during this time, it causes the selection signal sending circuit to open the line once and then restarts it. 1. A telephone set comprising: a control circuit for controlling the transmission of all digits of a dial signal for a DC impulse dial line after acquisition.
