Abstract

본 발명은 간이 전자 교환기에 관한 것으로, 특히 사설 ISDN망에 접속되는 다수개의 간이 교환기 내선 가입자가 사설 ISDN망의 D-채널을 이용하여 원격지 간이 교환기의 내선 단말기 가입자를 페이징으로 호출하고, 호출된 원격지 간이 교환기의 내선 가입자로부터 응답신호가 검출되면 B-채널을 통해 통화로를 형성하도록 한 것이다. 본 발명은 ISDN망에 접속되는 다수개의 간이 교환기에서 원격지 간이 교환기에 연결되어 있는 임의의 내선 단말기 그룹을 D-채널을 통해 지정한 후 B-채널을 통해 음성 메시지를 전송하여 지정된 그룹전체의 내선 단말기의 스피커폰을 통해 임의의 단말기 사용자를 호출하는 음성메세지를 방송으로 송출함으로써 통화를 요구한 발신자의 불필요한 대기시간이 축소되며, 한정된 선로를 ISDN망을 통해 효율적으로 사용하여 통신량의 증설과 이용요금의 저렴화를 제공하여 사용에 신리성을 제공한다.The present invention relates to a simple electronic switch, and in particular, a plurality of simple switch extension subscribers connected to the private ISDN network call the extension terminal subscribers of the remote switch by paging using the D-channel of the private ISDN network, When a response signal is detected from the extension subscriber of the simplified exchange, a call path is formed through the B-channel. According to the present invention, a group of extension terminals connected to an ISDN network is designated through a D-channel, and then a voice message is transmitted through a B-channel. Unnecessary waiting time of caller who requested a call is reduced by broadcasting voice message calling any terminal user through speakerphone, and the use of limited line is effectively used through ISDN network to increase the traffic volume and reduce the usage fee. Provide credibility to use.
