A technology that converts an ordinary household telephone line into a fast internet connection - around ten times faster than a regular 56k modem. The existing public network is no longer limited to voice, text, and low-resolution graphics and has the promise of providing multimedia (including full-motion video).
Asymmetric Digital Subscriber Line transmits data asymmetrically meaning the bandwidth usage is much higher in one direction than the other. Typical ADSL applications transmit 8 Mbps downstream and 768Kbps upstream, depending on the length of the local loop. This is particularly beneficial for Internet access, remote access and video on demand because downstream usage far exceeds upstream usage. Additional POTS is available simultaneously because the transmission of analog signals does not require as much bandwidth as data transmission. A typical ADSL connection is diagramed below: In addition to asymmetrical data flow, ADSL can also be configured to adapt to line conditions and maintain the highest possible connection. [ Picture
Acronym for : Asymmetric Digital Subscriber Line. A method of transferring data over regular phone lines using the same copper wires a regular phone lines uses. Download speeds are much faster than upload speeds, hence the "Asymmetric" inclusion. See also SDSL
