Abstract

본 발명은 키폰 시스템에 별도의 장치를 연결하므로서 일반전화기를 사용할 수 있도록 한 접속 방법에 관한 것으로, CPU(1), 휘딩회로부(2), DTMF(Dual Tone Multifrequency)수신회로부(3), 링 발생회로부(4), 릴레이 구동회로부(5), 데이타 송수신회로부(6)로 구성되는 하드웨어에 적용되는 운용방법에 있어서; 데이타가 들어오면, 일반전화기 데이타 인가를 조사하여 일반 전화기 데이타가 아니면 키폰 데이타로 처리하고 종료하여, 일반 전화기 데이타일 경우는 다이얼 데이타 인가를 조사하는 제 1단계(7 내지 9), 상기 제 1단계(7 내지 9) 수행 후, 다이얼 데이타가 아니면 일반데이타로 처리하고 종료하며, 다이얼 데이타이면 다이얼 데이타가 MFC(Multifrequency Code Signalling System)인가를 조사하는 제2단계(10, 11), 상기 제2단계(10, 11) 수행 후, MFC가 아니면 키폰 다이얼 데이타와 동일하게 처리한 후 종료하고, MFC이면 MFC테이블에 등록하고 종료하는 제3단계(12, 13)에 의해 수행된다.The present invention relates to a connection method for using a general telephone by connecting a separate device to the key phone system, the CPU (1), the feeding circuit unit (2), DTMF (Dual Tone Multifrequency) receiving circuit unit (3), ring generation An operating method applied to hardware consisting of a circuit section 4, a relay driving circuit section 5, and a data transmission / reception circuit section 6; When the data comes in, the first step (7 to 9), which checks whether the telephone data is authorized, processes it as key phone data if it is not the telephone data, and terminates. After performing (7 to 9), if the dial data is not the dial data, the process is processed and terminated, and if the dial data is the second step (10, 11) of checking whether the dial data is MFC (Multifrequency Code Signaling System), the second step After (10, 11), if not MFC, processing is performed in the same manner as the keyphone dial data and then terminated. If it is MFC, it is performed by the third step (12, 13) of registering and ending in the MFC table.
