Description

하울링방지용 메시지 송출중단이 가능한 전환자동응답 카세트레코더Switchable auto answer cassette recorder with interruption of howling prevention message

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제2도는 본발명에 의한 전화자동응답 카세트레코더의 회로구성도,2 is a circuit diagram of an automatic telephone cassette recorder according to the present invention;

제3도는 제2도의 동작흐름도.3 is a flow chart of FIG.

Claims (2)

전화자동 라인증폭기, 파워증폭기 등을 포함한 카세트 오디오회로부와, 듀플렉서와 수신앰프, 수신버퍼, 믹서 및 이와 관련된 회로구성으로 된 전화회로 접속부 및 D-RAM, 음성녹음재생 LSI, 마이콤등의 관련 구성으로 된 제어회로부의 관련 접속으로 되고, 제어회로부는 마이콤에 의해 자동응답을 위한 소정의 동작 흐름을 갖도록한 공지의 전화자동응답카세트 레코더에 있어서, 상기 전화회로 접속부(2)는 마이콤(4)의 콘트롤에 의해 수신 버퍼(17)의 출력을 감쇄기(14)측과, 온, 오프 시키는 TR스위치(13)와 이 TR스위치(13)를 통해 전송되는 신호를 감쇄시키는 감쇄기(14)를 부가하고, 듀플렉서(15)후단의 AT(28)와 릴레이 (8)간에 접속되어 AT(28)의 전류변동 값을 전압으로 변환시키는 전류/전압변환기(11)와 이 전류/전류 변환기(11)의 출력과 기준전압을 비교하여 마이콤(4)에 정보를 전송하는 비교기(12)를 구비시켜서 구성됨을 특징으로 하는 하울링방지용 메시지 송술중단이 가능한 전화자동응답 카세트레코더.Cassette audio circuit unit including telephone automatic line amplifier, power amplifier, etc., telephone circuit connection unit consisting of duplexer, receiving amplifier, receiving buffer, mixer and related circuits, and related configuration such as D-RAM, voice recording / reproducing LSI, micom, etc. In the known telephone automatic answering cassette recorder in which the control circuit portion is connected to the control circuit portion, and the control circuit portion has a predetermined operation flow for the automatic response by the microcomputer, the telephone circuit connection portion 2 controls the microcomputer 4. By the attenuator 14 side, the TR switch 13 for turning on and off the output of the reception buffer 17, and the attenuator 14 for attenuating the signal transmitted through the TR switch 13, (15) an output and reference of the current / voltage converter 11 and the current / voltage converter 11 connected between the later AT 28 and the relay 8 to convert the current variation value of the AT 28 into a voltage. Do not compare voltage An automatic telephone answering cassette recorder capable of interrupting howling message transmission, characterized by comprising a comparator (12) for transmitting information to the eCom (4). 자동응답 모드시에 메시지 변경 MFC코드 검출이 없을때에는 비교기(12)의 출력변화를 검출하여 송신전자 스위치(21)와 TR스위치(13)를 제어한 후 발신음 검출을 행하고, 비교기(12)의 출력변화가 없을 때에는 메시지송출을 종료하여 비트송출, 릴레이(8)구동을 행한 후 다시 비교기(12)의 출력변화를 검출하도록 하여 발신음 검출시 모터정지, 회선복구를 행하도록 하여서 자동모드시의 브릿지된 전화기 가 혹오프되면 응답메시지 송출을 중단시키고 용건메시지 출력레벨을 자동감쇄시켜 통화우선의 원칙으로 작동되도록한 제어프로그램을 특징으로 하는 하울링방지용 메시지 송출중단이 가능한 전화 자동응답 카세트 레코더.When there is no message change MFC code detected in the auto answer mode, the output change of the comparator 12 is detected, the transmission electronic switch 21 and the TR switch 13 are controlled, and the dial tone is detected and the output of the comparator 12 is output. If there is no change, the message transmission is terminated, the bit transmission, relay 8 drive, and then the output change of the comparator 12 is detected again. Then, the motor stop and line recovery are performed when the dial tone is detected. A telephone answering cassette recorder capable of interrupting the transmission of a howling prevention message, characterized by a control program that stops sending a response message when the phone is severely off and automatically reduces the output level of the message to operate on the principle of call priority. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
