댁내통신설비는 통신망에서 중요한 역할을 한다. 현재 국내의 댁내통신설비에 대한 기술은 멀티미디어 환경을 반영하여 작성되었으나, 초고속정보통신망의 멀티미디어서비스를 수용하기 위해서는 미흡하다. 이에 본 논문에서는 댁내통신설비의 고도화를 위하여 운영환경요소를 분석하고 국내외 표준화 현황을 살펴보고 현재의 댁내통신설비의 운영환경에 대한 현장조사를 통한 문제점과 개선방안을 제시하였다.

In this paper, we have analyzed the effects from the change of separation distance between grounding equipment at end of telecommunication line and the inducting facilities in power inducting situation. In the result of measurement, we can see that as the separation distance between grounding equipment ant end of telecommunication line and the inducting facility become longer, the induced noise level and PIF level is decreased. From the another experiment results about the effect of changing the impedance size in both ends of telecommunication line, however, we already knew that as the ground impedance at either end of the telecommunication line become grower, the noise level is increased, and as the ground impedance at either end of the telecommunication line become smaller, the noise level is decreased. Hence we can not define the relationship exactly between separation distance from inducting facility to inducted facility and the induced noise level because when the grounding equipment is moved, its impedance size is changed too. In conclusion, changing the separation distance between grounding equipment at end of telecommunication line and the inducting facilities have not influence on the induced noise level.
