A dial controller 2 for driving the control signal of 8) and outputting a pre-stored dial signal, and a line controller 14 for driving the dial signal of the dial controller 2 by driving the control signal of the microcomputer 8; And a signal control unit 4 which switches according to the output level of the line control unit 14 to output various signals of the switching station to the handset 5, and transmits the dial signal of the dial control unit 2 to the switching station; The various output signals of the signal controller 4 A band pass filter unit 10 for filtering, a call tone, a call tone, a call tone detector 11, 12, 13, and the call tone for detecting a busy tone, a call tone, and a dial tone filtered by the band pass filter unit 10; Automated telephone apparatus characterized in that it is configured as a signal level detection unit 9 which converts the output signals of the detection unit 11, the ring tone detection unit 12 and the divergent sound detection unit 13 into digital signals and inputs them to the microcomputer 8. Redial device. 재다이얼버튼(6)이 하이전위로 입력되면 마이컴(8)은 라이제어부(14) 및 신호제어부(4)를 턴-온시킴과 아울러 신호레벨감지부(9)를 체크하여 그 신호레벨감지부(9)로부터 로우전위의 발신음이 출력되면 라인제어부(14)를 오프시키고 하이전위의발신음이 출력되면 라인제어부(14) 및 다이얼제어부(2)를 턴-온시켜 재다이얼번호를 교환국으로 송출하고, 이후 마이컴(8)은 다시 신호레벨감지부(9)를 소정시간(T1)체크하여 소정시간(T1)동안 호출음이 로우전위로 입력되면 통화모드로 세팅하고, 소정시간(T1) 이상 호출음이 하이전위로 입력되거나 통화중음신호가 하이전위로 입력되면 소정시간(T2)동안 라인제어부(14)를 오프시켜 전화루프를 차단하고, 소정시간(T2)이 경과되면 다시 라인제어부(14) 및 다이얼제어부(2)를 턴-온시켜 재다이얼번호를 교환국으로 송출하며, 상기에서 전화루프가 차단된 후 소정시간(T2)대기상태에서 링신호검출부(7)로부터 링신호가 검출되면 통화모드로 세팅하고, 통화모드가 끝나고 훅크스위치(3)가 턴-온되면 소정시간(T2)을 재설정하여카운트한 후 재다이얼링을 소정횟수로 반복수행하여 동작을 종료하는 것을 특징으로 하는 전화기의 자동 재다이얼방법.When the redial button 6 is input at the high potential, the microcomputer 8 turns on the ly control unit 14 and the signal control unit 4, checks the signal level detection unit 9, and checks the signal level detection unit. (9), when the low potential dial tone is output, the line control unit 14 is turned off, and when the high potential tone is output, the line control unit 14 and the dial controller 2 are turned on to transmit the redial number to the switching center. , since the microcomputer (8) is a predetermined time (T 1) set in the communication mode, and when the back signal level detector (9) a predetermined time (T 1) Check the ring-back tone is input to the low potential for a predetermined time (T 1) or more ring-back tone is when the input to the high potential or the busy tone signal is input to the high potential turns off the line control unit 14 for a predetermined time (T 2) block the telephone loop, and a predetermined time (T 2) is when passed back line control (14) and dial control unit (2) are turned on to redial the number to the switching center. When the ring signal is detected from the ring signal detection unit 7 in the standby state for a predetermined time (T 2 ) after the telephone loop is cut off, the call mode is set to the call mode, and the hook switch 3 is turned on. If it is turned on, after resetting the predetermined time (T 2 ) to count and repeat the redialing a predetermined number of times, the automatic redial method of the telephone, characterized in that the operation is terminated. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
