xDSL technology allows the use of the copper twisted pair network already in place to virtually every home in the USA for high-speed data traffic, piggybacked on the voice network already in place. Besides the Internet, applications include remote LAN access, video conferencing, medical diagnosis, distance learning, video on demand and others ...

2013年4月19日 · DSL（Digital Subscriber Line数字用户环路）技术是基于普通电话线的宽带接入技术，它在同一铜线上分别传送数据和语音信号，数据信号并不通过电话交换机设备，减轻了电话交换机的负载；并且不需要拨号，一直在线，属于专线上网方式，这意味着使用XDSL上网并不 ...

primarily two different schemes that are under consideration, Discrete MultiTone Modulation (DMT) and Carrierless Amplitude Phase Modulation (CAP). The coding scheme favored by the standards bodies is DMT modulation.

2017年5月3日 · DSL varieties called xDSLs are handled separately and compared in terms of data transmission speeds (download / upload), structures (symmetric / asymmetric) and transmission distances. And it is...

2000年6月15日 · In this tutorial we take a detailed look at the International Telecommunication Union (ITU) Study Group 15's G.99x series recommendations (G.lite, G.dmt, G.hs, etc.) that provide a set of worldwide xDSL standards for broadband Internet access.

XDSL（Extended Digital Subscriber Line）是一系列基于传统电话线路的宽带接入技术的统称。 这些技术利用现有的铜质双绞线，通过较高频率和相应的调制技术，实现高速数据传输。
