Abstract

셀룰라 기지국과 무선통신을 통한 셀룰라 통화회선을 구비하는 사설교환장치가 개시되고 있다. 본 발명에 따르면 국선을 유선에 의해 전화국과 연결될 뿐만 아니라 셀룰라 기지국과의 무선통신에 의해 셀룰라 통화회선을 확보하여 상기 셀룰라 통화회선을 이용한 이동 사설 전자교환장치로 사용할 수 있는 장점이 있다. 또한 본 발명은 유선과 무선을 이용한 국선 통화선로를 구비하므로 유선의 단선에도 무선을 이용한 통화 및 교환기능을 수행할 수 있는 장점을 가진다.A private switching apparatus including a cellular base station and a cellular communication line through wireless communication is disclosed. According to the present invention, not only a trunk line is connected to a telephone station by a wire line, but also a cellular communication line is secured by wireless communication with a cellular base station, which can be used as a mobile private electronic switching device using the cellular telephone line. In addition, the present invention has an advantage that can be performed by the call and the exchange function using the wireless even in the disconnection of the wire because it is provided with a CO line call line using a wired and wireless.
