ADSL（AsymmetricDigitalSubscriberLine）亦即非对称数字用户线技术。它使用现有的一对铜双绞线（即一般电话线），为用户供应上、下行非对称的传输速率（带宽），上行（从用户到网络）为低速传输，可达1MKbps；下行（从网络到用户）为高速传输，可达8Mbps，传输距离约为3KM—5KM。

(ADSL (AsymmetricDigitalSubscriberLine) is the asymmetric digital subscriber line technology. It uses an existing pair of copper twisted pairs (that is, general telephone lines) to provide users with asymmetrical transmission rates (bandwidth) for uplink and downlink. The uplink (from the user to the network) is low-speed transmission, up to 1MKbps; From the network to the user) is high-speed transmission, up to 8Mbps, and the transmission distance is about 3KM-5KM.)
