Abstract
본 발명은 전전자 교환기에 사용되는 글로발 버스 방식의 통신 회로에 있어서, 그 통신 방식에 따라 호환성 있게 사용할 수 있는 유니 글로발 버스 호환장치에 관한 것으로, 종래에는 전전자 교환기의 글로발 버스 통신방식은 RS 485 통신 방식을 사용하는 통신 회로가 있고, DS 3662 버스 드라이브 방식의 유니 버스를 사용한 통신 회로가 있는데, 이와 같은 두 방식을 사용하기 위해서는 각각 마다 해당 회로를 구비해야만 했으나, 본발명에서는 전전자 교환기의 글로발 버스 통신 방식중에서 RS 485 통신 방식을 사용하는 통신 회로와 DS 3662 버스 드라이브 방식의 유니 버스을 사용한 통신 회로를 그 통신 방식에 따라 호환성 있게 선택 사용할 수있음으로써 상기 결점을 개선시킬 수 있는 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a global bus compatible apparatus that can be used interchangeably according to the communication method in a global bus communication circuit used in an electronic switch. There is a communication circuit using a communication method, and there is a communication circuit using a Universe of the DS 3662 bus drive method. In order to use these two methods, each has to have a corresponding circuit. The shortcomings can be improved by using a communication circuit using an RS 485 communication method and a communication circuit using a DS 3662 bus drive type universe compatible among the bus communication methods.
