Internet的高速发展使ADSL技术1997年以来在全世界范围内得到大规模的应用 ,促进了ADSL技术各项指标的标准化。比较基于两种不同线路编码和调制技术(CAP &DMT)的产品的各自特点和一种新的组网方式以及它们对产品应用的影响 ,详细讨论了ADSL技术在实际应用推广上所需解决的问题 ,最后比较两种不同网络结构的ADSL宽带接入技术及提出发展ADSL宽带接入技术的策略。
The rapid development of Internet ADSL technology has been in large-scale applications around the world since 1997, promoting the standardization of various indicators of ADSL technology. Compares the respective characteristics of products based on two different line coding and modulation technologies (CAP & DMT) and a new networking mode and their impact on product applications, and discusses in detail the problems that ADSL technology needs to solve in practical application and promotion Finally, we compare ADSL broadband access technologies with two different network structures and propose strategies for developing ADSL broadband access technologies.
