摘要

本論文實驗研究出新一代國際數據專線(Ethernet Private Leased Circuit; EPLC)取代傳統國際數據專線(International Private Leased Circuit; IPLC)，經過多種電路架構實驗與透過下一世代同步數位階層網路(Next Generation Synchronous Digital Hierarchy; NG-SDH)建置而成，利用新式交換機的三項技術虛擬連結(Virtual Concatenation; VCAT)、連結容量調整架構(Link Capacity Adjustment Scheme; LCAS)和通用訊框規範(Generic Framing Procedure; GFP)改善傳統國際數據電路傳輸架構，透過實體電路建置創新與軟體交換技術的提升，硬體技術藉由NG-SDH交換機支援的乙太網路(Ethernet port)傳輸端口，取代原本的同軸電纜線(coaxial cable)的傳輸，提高國際數據電路傳輸效率、電路品質度，將國際電路信號傳送距離延長，突破原有的距離限制，透過電路頻寬的新技術，使得電路頻寬擴增進而增加企業用戶的使用戶數、大幅增加電信業者的營收，同時減少企業客戶設備成開銷與降低網管維護的困難度。
由於用戶端的需求日漸多元化，傳統的電路傳輸模式已經無法負荷，透過光纖逐漸普及與成熟，經過研究與多次電路實驗，找到一種新電路架構的國際數據電路(EPLC)，符合時代需求與現在資訊蓬勃發展的世代接軌，為人類文明進步推向更美好的未來。

This paper presents a new generation of international data lines (Ethernet Private Leased Circuit; EPLC) to replace the traditional International Data Line (International Private Leased Circuit; IPLC), through a variety of circuit architecture through experiments with next-generation SDH network (Next Generation Synchronous Digital Hierarchy; NG-SDH) network deployment switch is made, the use of modern technology three virtual switch link (Virtual Concatenation; VCAT), Link Capacity Adjustment architecture (Link Capacity Adjustment Scheme; LCAS) and generic frame specification (Generic Framing Procedure; GFP) to improve the traditional structure of international datatransmission circuit, build through the physical circuit switching technology innovation and upgrading software and hardware technology by NG-SDH switch supports Ethernet (Ethernet port) transfer port, replacing the original coaxial cable (coaxial cable) transmission and improve the international data circuit transmission efficiency, quality and degree of the circuit, the international circuit signal transmission distance is extended, breaking the original distance limitations, the circuit bandwidth through new technology, making the circuit bandwidth amplification leading to an increased number of households use enterprise users, a substantial increase telecommunications the industry's revenue, while reducing corporate overhead and reduce customer equipment into network maintenance difficult.
As increasingly diverse client needs, the traditional circuit transfer mode has been unable to load the increasing popularity and mature through optical fiber, through research and multiple circuit experiment, find new circuit architecture of international data circuits (EPLC), meet the requirements of the times and the present information booming generation standards for human civilization and toward a better future.
