Abstract

자동응답 전화기는 원격지에서 OGM을 들을때 자동응답기에서 송출되는 송출메세지 레벨을 제어하기 위한 것으로 이를 위해 송수화기부와 오디오부 사이에 제어부의 제어를 받는 신호 제어부를 설치하고 있다.The answering machine has a signal control unit under the control of the control unit between the handset unit and the audio unit for controlling the outgoing message level transmitted from the answering machine when the OGM is heard from a remote place.

송출메세지 송출레벨제어는 DTMF 검출부에서 검출되는 DTMF 톤을 비교하여 #톤일 경우 송출레벨을 크게하고 *톤일 경우 송출레벨을 작게 한다.Outgoing message Outgoing level control compares the DTMF tones detected by the DTMF detection unit to increase the outgoing level for # tones and to reduce the outgoing level for * tones.
