Abstract

본 발명은, 종래의 키폰시스템에서 필요시 일반전화기를 연결시켜 내선간의 교환기능을 수행하도록 사용되었으며, 또한 주로 사무실에서 사용되는 소용량 교환기로써 필요에 따라 지정된 키폰 전화기에서 내선 번호별로 통화등급을 나누어 통화를 제한하여 사용하였다. 그러나 이러한 시스템에서는 지정된 프로그램 모드를 임의로 변경하여 통화제한을 해제하여 사용할 수 있을 뿐 아니라, 하등급의 키폰 사용자가 통화가능한 내선번호에 있는 사람이 부재시 통화제한을 받지 않고 사용할 수 있어, 통화제한 본래 기능을 수행할 수 없는 단점을 보완하기 위한 것이다. 따라서 본 발명은 상술한 단점을 보완하기 위해 키폰시스템에 키스위치를 사용하여, 사용자 부재시 키스위치(key s/w)를 잠금(lock)시킴으로서 불필요한 통화를 제한하거나, 프로그램 모드를 임의로 변경하여 통화하는 것을 방지하기 위한 장치 및 방법에 관한 것이다.The present invention has been used to perform the exchange function between the extension by connecting a general telephone when necessary in the conventional keyphone system, and also divided the call grade by extension number in the designated keyphone telephone as needed as a small-capacity exchanger mainly used in the office It was used to limit. However, in such a system, the designated program mode can be arbitrarily changed to release the call restriction, and the lower-level keyphone user can use the extension number without receiving a call restriction in the absence of the call extension. To compensate for the inability to perform. Therefore, the present invention uses a key switch in the key phone system to compensate for the above-mentioned disadvantages, by limiting unnecessary calls by locking the key switch (key s / w) in the absence of the user, or by changing the program mode arbitrarily An apparatus and a method for preventing the same.
