Abstract

본 발명은 디지탈키폰에 관한 것으로, 특히 1개의 내선회선에 2개의 단말기를 연결하여 각각 독립적으로 사용할수 있도록 하는 디지탈키폰에 관한 것이다.The present invention relates to a digital key phone, and more particularly, to a digital key phone that can be used independently by connecting two terminals to one extension line.

본 발명은 시스템 설치비용을 대폭절감함과 동시에 동일크기의 다른 시스템에 비하여 2배의 내선단단말기를 운용할수 있다.The present invention can significantly reduce the installation cost of the system and at the same time operate twice the extension terminal compared to other systems of the same size.
