本論文提出了用戶迴路遠端量測系統改良的設計，並探討用戶迴路的線路基本特性之研究。用戶迴路自動測試設備的基本特性探討，包含:類比錶頭的量測分析、數位錶頭的量測分析、用戶迴路障礙的種類與分析…等。
提出數據化、WEB化之改良式類比錶頭的設計，應用在用戶迴路遠端量測系統上，同時以簡單的通訊協定為架構，設計出解決用戶迴路瞬斷對寬頻網路的影響，其構思概念：在用戶迴路自動測試設備上將類比錶頭所反應的線路特性，以類比轉數位方式，將所得的數據透過網路傳輸，在任何網路擷取點以圖形化類比錶頭型態，重新顯現在電腦螢幕上，此項改良式類比錶頭的設計，解決了長久以來用戶迴路自動測試設備無法由本地以類比錶頭方式遙測遠端用戶迴路功能上的缺失。以網路技術完成人力科技在用戶迴路量測上的無限延伸，對遠端用戶迴路障礙的排除，提供一個快速而有效的解決方案。

This thesis has got the design and improvement for the subscriber loop remote measured system and analytics of the subscriber loop’s characteristic, basic characteristic discussion of the subscriber loop, maintenance of automatic testing system includes digital meter measure, analog meter measure, troubles of subscriber loop, the effect of subscriber loop has half connect for broadband network.
Designs the image displaying analog meter on the personal computer’s screen that can provide performance for local users to processing the remote telephone troubles on network before digitalize and simulation the analog meter of voltage by analog to digital converters, it’s a good solution for subscriber loop remote test equipment in future.
