asymmetric digital subscriber line

asymmetric digital subscriber line
非对称数字用户线路
Asymmetric Digital Subscriber Line is a term for one-way T1 transmission of signals to the home over single twisted-pair wiring already going to homes in the prior art. ADSL modems are attached to twisted pair copper wiring. ADSL is often provisioned with greater downstream than upstream rates (hence the term "asymmetric"). These rates are dependent on the distance a user is from the central office and may vary from as high as 9 Mbps to as low as 384 Kbps.
电话线主要标准有：(1)ADSL(Asymmetric Digital Subscriber Line，非对称数字用户线路)。ADSL采用频分多路复用方式，在一对双绞铜线上，进行非对称高速数据传输。

非对称式数位用户回路（=ADSL）
四种DSL技术之一。ADSL是设计用於传送下游频宽（downstream）（从局端到用户端）多於上游频宽（upstream）的情况下。下频频宽的范围1.5到9Mbps，而上游频宽范围则为16到640Kbps。ADSL在单一双绞铜线上，传输距离可达18,000尺（5,488公尺）以上。
