Abstract

본 발명은 다이얼 패드를 눌렀을 때 키톤발생을 소프트 웨어적으로 제어할 수 있는 키폰전화기의 키톤 발생제어 방법에 관한 것으로, 기존에는 키폰전화기에 있어서, 키톤을 발생하기 위한 수단으로 많은 하드웨어의 부품을 사용하므로 회로구성이 복잡할뿐만 아니라 원가가 상승하는 문제가 있어, 본 발명에서는 소프트웨어에 의해서 키톤 발생시간을 임의로 변경가능하게 하고, 사용자가 소리를 듣게 함으로써 다이얼 패드를 눌렀는지를 용이하게 판단할 수 있도록 한 것이다.The present invention relates to a key tone generation control method of a key phone telephone that can control the key tone generation by software when the dial pad is pressed. Conventionally, in a key phone telephone, a large number of hardware components are used as a means for generating a key tone. Therefore, the circuit configuration is complicated and the cost increases. In the present invention, the keytone generation time can be arbitrarily changed by software, and the user can easily determine whether the dial pad has been pressed by listening to the sound. will be.
