Claims (1)

키폰 시스템의 자동 국선 선별 방법에 있어서, 시스템을 초기화하고 호처리를 실행하여 모든 국선의 국선 종류가 선택되었는가를 체킹하는 제1과정과, 상기 제1과정에서 모든 국선종류가 선택되지 않았을때 음성통로가 연결되었는가를 체킹하는 제2과정과, 상기 제2과정에서 음성통로가 연결되어 있지 않은 상태에서 선택되지 않은 국선이 휴지상태에 있으면 국선의 음성통로와 톤 검출과의 통로를 연결시키는 제3과정과, 상기 제2과정에서 음성 통로가 연결상태에 있을때 국선의 음성통로와 톤 검출의 음성통로와의 연결 여부를 체킹하는 제4과정과, 상기 제4과정의 연결상태에서 소정시간에 발신음이 검출되면 DTMF음성통로와 국선 음성통로를 연결하고 발신음이 검출되지 않으면 국선이 연결되지 않음으로 처리하여 다음 국선을 처리하는 제5과정과, 상기 제4과정의 DTME음성통로와 국선통로의 연결상태에서 소정시간내 발신음이 검출되면 국선을 펄스방식으로 하고 발신음이 검출되지 않으면 국선을 톤방식으로 저장 처리하는 제6과정으로 이루어짐을 특지응로 하는 국선종류 자동 선별방법.In the automatic trunk line screening method of a key phone system, a first process of initializing the system and executing call processing to check whether the trunk line types of all trunk lines are selected, and a voice path when all the trunk line types are not selected in the first process A second process of checking whether the circuit is connected, and a third process of connecting a passage between the voice passage of the trunk line and the tone detection when the trunk line is not selected while the voice passage is not connected in the second process. And a fourth step of checking whether the voice path of the trunk line and the voice path of tone detection are connected when the voice path is in the connected state in the second step, and detecting a dial tone at a predetermined time in the connected state of the fourth step. The fifth step of connecting the DTMF voice path and the trunk line voice path and processing the next trunk line by treating the trunk line as not connected if no dial tone is detected; In case that a dial tone is detected within a predetermined time in the connection state of the DTME voice passage and the trunk line passage of the fourth step, a sixth step of storing the trunk line in a tone method if the dial tone is detected is not detected. Automatic selection of CO line types. ※ 참고사항 : 최초출원 내용에 의하여 공개되는 것임.※ Note: This is to be disclosed by the original application.
