Abstract

본 발명은 키폰시스템에서 국선에 따라 링신호를 다르게 출력하는 기술에 관한 것으로, 종래의 키폰시스템이 있어서는 국선을 통해 외부로부터 전화가 걸려올 때 착신 국선에 관계없이 내선에 동일한 링신호를 출력하게 되므로 여러 국선을 통해 동시에 전화가 걸려올 때 인접한 그룹의 키폰전화기에 동일한 종류의 링신호가 울리게 되고, 이로 인하여 사용자는 자기 그룹에 걸려온 전화와 다른 그룹에 걸려온 전화를 구분하여 사용하는데 어려움이 있었다. 따라서, 본 발명은 이를 해결하기 위하여, 국선별로 임의의 링신호를 부여하여 메모리에 저장시키고, 키폰시스템에 수용된 다수개의 국선 중 임의의 국선을 통해 전화가 걸려오는 것을 감지한 후 해당 국선의 링신호 제어데이타를 상기 메모리에서 읽어와 해당 키폰전화기에 송출하도록 하였다.The present invention relates to a technology for outputting a ring signal differently according to a trunk line in a key phone system. In the conventional key phone system, when a call is received from the outside via a trunk line, the same ring signal is output to an extension regardless of the incoming trunk line. The same kind of ring signal sounds to the adjacent group's telephone phones when the call is made through multiple trunk lines at the same time, which makes it difficult for the user to distinguish between the telephones in the group and the telephones in the other group. Accordingly, in order to solve the problem, the present invention provides an arbitrary ring signal for each trunk line and stores it in a memory, and detects a call coming through any trunk line among a plurality of trunk lines accommodated in the keyphone system, and then rings the ring line of the corresponding trunk line. The control data was read from the memory and sent to the corresponding key phone.
