Abstract

본 발명은 키폰 시스템에 관한 것으로, 아날로그 키폰 시스템을 종합정보통신망인 디지탈 국선에 접속하여 사용할 수 있도록 국선을 변환시켜 주는 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a key phone system, and more particularly, to an apparatus for converting a trunk line so that an analog key phone system can be connected to a digital trunk line.

본 발명은 하나의 국선을 통해 두개의 키폰 시스템이 통화할 수 있는 종합정보통신망에 아날로그 키폰 시스템을 접속하여사용하므로 국선사용에 효율성을 제공하며, 하나의 국선을 통한 2개의 전화기 사용으로 선로의 사용요금이 절감되어 통신에 신뢰성이 제공된다.The present invention provides an efficiency in the use of CO lines by connecting an analog key phone system to a general information communication network through which two key phone systems can communicate through one CO line, and using two lines through one CO line. The cost is reduced, providing reliability for communications.
