Abstract

본 발명은 복수대 접속된 전화기 상호간의 호출 및 인터폰기능이 가능하도록 된 장치에 관한 것으로, 특히 전자교환기를 이용하지 않고 동일 회선에 연결된 복수대의 전화기에 있어서 전화기의 다이얼버튼을 이용한 호출 및 인터폰 기능을 가능하게 한 장치에 관한 것인 바, 본 발명은 착신통화시에 전화기의 다이얼버튼을 누름으로써 동일 회선에 접속된 다른 전화기에 호출신호를 출력할 수 있고, 또 착신대기상태(통화중이 아닌 상태)에서 동일 회선에 접속된 전화기 사이의 인터폰 기능이 가능하도록 된 장치를 제공함에 그 목적이 있다.The present invention relates to a device which enables calling and intercoming functions of a plurality of connected telephones. In particular, the present invention relates to a calling and intercoming function using a dial button of a telephone in a plurality of telephones connected to the same line without using an electronic exchanger. The present invention relates to a device which enables the present invention. The present invention can output a call signal to another telephone connected to the same line by pressing a dial button of the telephone during an incoming call, and the call waiting state (state not being in a call). It is an object of the present invention to provide a device that enables the interphone function between telephones connected to the same line.

이러한 본 발명에 따르면, 전화가 걸려왔을 때 전화기의 다이얼버튼을 누름으로써 동일 회선에 접속된 다른 전화기호 호출신호를 출력할 수 있을 뿐만 아니라, 통화중이 아닐 때에는 동일 회선에 접속된 다른 전화기를 호출하여 인터폰으로서도 사용할 수가 있게 된다.According to the present invention, when a telephone call is made, not only the telephone call signal of another telephone line connected to the same line can be output by pressing the dial button of the telephone, but also the other telephone connected to the same line is called when not in a call. Therefore, it can also be used as an interphone.
