Claims (1)
다이얼버튼부(11)로 부터 신호를 입력받아 제어부(8)에서 펄스신호를 송출한 후 링백톤 검출부(14)로 부터 신호를 입력받아 통화 연결상태를 감지하여 링백톤상태를 유지하고 있지 않으면 톤 다이얼모드로 자동전환하고 훅스위치(HS)입력후 펄스 다이얼모드로 자동 복구되는 과정으로 이루어짐을 특징으로 하는 전화기의 다이얼모드 자동변환방법.If the signal is received from the dial button unit 11, the control unit 8 sends out a pulse signal, and then receives the signal from the ringback tone detection unit 14 to detect the call connection state and maintains the ringback tone state. A method for automatically converting a dial mode to a telephone, characterized in that the process is automatically switched to the dial mode and automatically restored to the pulse dial mode after the hook switch (HS) is input.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
