But these bit rates are far from the maximum possible on a twisted pair alone. One process that limits bandwidth and signal strength is the steady attenuation of the signal as it travels down the line, with the higher frequencies being affected more severely. Greater capacity is therefore available if the lines are kept short. Originally, the Discrete Multitone approach was intended for sending entertainment video over telephone wires. Because such use relies principally on one-way transmission, most of the subchannels were devoted to the "downstream" signal, carrying about 6 Mbps, with about 0.6 Mbps available in the other direction. This asymmetric form of DSL has become known as ADSL, and the signal coding is now a worldwide standard. Although the video application has not yet borne fruit, asymmetric transmission fortuitously lends itself to browsing on the World Wide Web.
