碩士 === 國立臺北科技大學 === 電資碩士在職專班研究所 === 101 === 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.
