Abstract
본 발명은 스피커폰을 이용한 자동국선 연결장치에 관한 것으로, 종래의 스피커폰은 전화가 걸려올 경우 하던일을 멈추고 사용자가 수동으로 통화키를 조작해야만 전화통화를 할 수 있는 문제점이 있었다. 본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 링신호 착신시 이를 감지하여 알려주는 링감지부와, 상대방이 전화를 끊으면 발생하는 VOX를 감지하는 VOX감지부와, 정해진 링 응답횟수를 저장하기 위한 이이피롬과, 상기 링감지부로부터의 링신호를 카운트 하여 기설정된 응답횟수가 되면 통화로를 연결하기 위한 제어신호를 출력하고 상기 VOX신호가 입력되면 전화통화로를 차단하기 위한 제어신호를 출력하는 등 시스템을 총괄제어하는 씨피유와, 상기 씨피유의 제어신호에 따라 통화로를 연결/차단하여 음성신호를 송/수신하는 통화연결부와, 마이크로부터 입력된 음성신호를 그에 따른 주파수로 변환하여 상기 통화연결부에 전달하는 음성변환부와, 상기 통화연결부로부터의 음성신호를 증폭하여 스피커를 통해 출력하는 음성증폭부로 구성한 스피커폰을 이용한 자동국선 연결장치를 창안한 것으로, 이의 작용을 통해 링신호를 카운트하여 기 설정된 횟수만큼 링이 울리면 자동으로 전화통화로를 연결하고 통화종료 후에는 VOX기능을 이용하여 자동으로 통화를 종료함으로써 핸드프리 상태로 통화를 할 수 있는 효과가 있다.The present invention relates to an automatic trunk line connection device using a speaker phone, the conventional speaker phone has a problem that can stop the work when a call is received and make a phone call only when the user manually manipulates the call key. The present invention is to solve the conventional problems as described above, ring detection unit for detecting and notifying when receiving a ring signal, the VOX detection unit for detecting the VOX generated when the other party hangs up, and to store a predetermined number of ring responses Outputs a control signal for connecting a call path when a predetermined response number is counted by counting a ring signal from the ring detecting unit and outputting a control signal for blocking a phone call path when the VOX signal is input. CPI, which collectively controls the system, a call connection unit for connecting / blocking a call path according to the CPI control signal, and a voice connection unit for transmitting / receiving a voice signal, and converting a voice signal input from a microphone into a frequency corresponding thereto. Voice conversion unit for transmitting to the connection unit, and a voice amplifier for amplifying the audio signal from the call connection unit and outputs through the speaker It is an automatic trunk line connecting device using one speakerphone. Through this function, the ring signal is counted, and when the ring rings for a preset number of times, it automatically connects to the telephone line and ends the call using the VOX function after the call ends. Ending has the effect of making a call in a hands-free state.
