Abstract
본 발명은 디지틀 커폰에서 발생되는 제어 신호에 의해 여러 단계의 링거(Ringer) 볼륨과 음색을 제어할 수 있도록 한 키폰의 링거 발생장치에 관한 것으로, 외부로부터 선택되는 음색(cadence)과 볼륨의 레벨을 디지틀적으로 처리하는 아날로그 다중화부; 외부로부터의 호출을 이니하여 링거 인에이블시노를 출력하는 중앙처리장치; 상기 중앙처리장치에서 발생되는 링거 인에이블신호에 따라 링거를 발생하는 링거 발생부 및; 상기 링거 발생부에서 출력되는 링거를 사용자가 설정한 레벨만큼 증폭하여 스피커로 출력하는 증폭부를 구비하는 것을 특징으로 하여 다수의 키폰을 사용할 때 링거의 음색에 따라 키폰을 구별하기가 쉽고, 상기 클럭을 분주하기 위한 복잡한 회로가 불필요한 효과가 있다.The present invention relates to a ringer generating device of a keyphone that can control ringer volume and sound of various stages by a control signal generated from a digital coupon. An analog multiplexer for digitally processing; A central processing unit for outputting a ringer enable signal through an external call; A ringer generator for generating a ringer according to a ringer enable signal generated by the central processing unit; And amplifying part amplifying the ringer output from the ringer generating unit to a level set by a user, so that it is easy to distinguish keyphones according to the tones of ringers when using a plurality of keyphones. Complex circuits for dispensing have unnecessary effects.
