Abstract

본 발명은 상대국의 데이타 유니트에 사용자가 없더라도 자국에서 상대국을 역순환(Loop back)상태로 하여 상대국의 네트워크를 용이하게 제어토록 한 원격 데이타 서비스 유니트 제어장치에 관한 것이다. 종래의 데이타 서비스 유니트는 상개국 DSU의 콘피크(CONFIG)값이 자국 DSD와 상이하거나 상대국 DSU에 에러가 발생하여 자국 DSU에 에러가 검출될 경우 상대국 DSU에 사용자가 존재해야만 에러 수정이 가능한 번거로움이 있을 뿐만 아니라 데이타 통신의 효율성이 저하되는 문제점이 있었다. 이러한 종래 기술의 문제점을 해소코자 하여 본 발명에는 상대국 DSU에 사용자가 없더라도 상대국 DSU의 콘피그값을 제어할 수 있는 네트워크 관리 및 데이타 통신의 효율성을 향상시키고자 한 것이다.The present invention relates to a remote data service unit control apparatus which allows a counter station to be loop-backed in its own station even if there is no user in the data unit of the counter station so as to easily control the network of the counter station. In the conventional data service unit, if the config value of the DSU of the host country is different from that of the own station's DSD or an error occurs in the counterpart DSU and an error is detected in the own station's DSU, the user must exist in the counterpart's DSU to correct the error. In addition to this there was a problem that the efficiency of data communication is reduced. In order to solve the problems of the prior art, the present invention is intended to improve the efficiency of network management and data communication that can control the config value of the counterpart DSU even if there is no user in the counterpart DSU.
