내선전화기에서 톤 및 링 발생방법How to generate tone and ring in extension telephone

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

제1도는 본 발명을 수행하기 위한 회로도, 제3도는 본 발명에 의해 발생된 링 및 톤의 파형도.1 is a circuit diagram for carrying out the present invention, and FIG. 3 is a waveform diagram of rings and tones generated by the present invention.

Claims (1)

CPU를 구비한 간이교환 시스템의 내선전화기에 있어서, 주장치로부터 수신되는 데이터를 입력하여 저장하는 제1과정과, 상기 제1과정에서 저장되어진 데이터를 독출하여 링 또는 톤데이터인가 분석한 다음 그 종류에 따라 해당 톤이나 링 발생을 지정하는 제2과정과, 상기 제2과정에서 설정된 해당 톤이나 링신호를 발생하여 해당 출력포트를 통해 송출하는 제3과정으로 이루어짐을 특징으로 하는 톤 및 링 발생방법.In an extension telephone of a simple switching system equipped with a CPU, a first step of inputting and storing data received from a main device, and reading out the data stored in the first step and analyzing ring or tone data is performed. And a second process of designating a corresponding tone or ring generation, and a third process of generating the corresponding tone or ring signal set in the second process and transmitting the corresponding tone or ring signal through the corresponding output port. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
