PURPOSE:To improve the operability and operation reliability by automating the process from a calling to the sending of control information and automating the changeover of a dial signal mode. CONSTITUTION:When a call request to a communication opposite party registered in a dial information memory A is inputted, a dial pulse is sent automatically in response to dial number information, and a control signal is sent automatically in succession to the reply of the communication party by the call. Thus, a subscriber stores the dial number information and control information in advance in the dial information memory A and the call and the control signal are sent by having only to input a call request of the communication party. Since the changeover of the dial signal mode is applied automatically by a dial signal mode revision means D, the dial signal mode left unswitched or the like is prevented surely. Thus, the operability and the reliability of sending a dial signal are enhanced.
