摘要
给出ADSL2/ADSL2plus接入技术的概念,重点分析ADSL2/ADSL2plus的编码调制、速率自适应(SRA)、能量管理、双端测试(DELT)等技术特性及其在接入应用中的具体实现,给出ADSL2/ADSL2plus一个清晰的面貌,最后对ADSL2/ADSL2plus的应用情况和发展前景进行了介绍。通过分析,使读者更清楚认识ADSL2/ADSL2plus,促进ADSL2/ADSL2plus接入在电信网中推广应用。
<Abstrcat>The concepts of the ADSL2/ADSL2plus are given.Analyze the new feature of ADSL2/ADSL2plus, such as specific coding and modulation,seamless rate adaptation (SRA),power management,double ended line test (DELT),etc.And present the theory and solid technologic realization in ADSL2/ADSL2plus access application . Introduce the application of ADSL2/ADSL2plus currently and in the future.The purport of this paper is to make ADSL2/ADSL2plus more clear to readers,advance the progress of ADSL2/ADSL2plus application in telecommunication network.
