xDSL

Digital Subscriber Line (DSL), is a family of technologies that provides digital data transmission over the wires of a local telephone network. xDSL refers to the different variants of DSL. DSL originally stood for digital subscriber loop, although in recent years, the term digital subscriber line has been widely adopted as a more marketing-friendly term for Asymmetric Digital Subscriber Line  (ADSL), which is the most popular version of consumer-ready DSL. DSL can be used at the same time and on the same telephone line with regular telephone, as it uses high frequency, while regular telephone uses low frequency.

Typically, the download speed of consumer DSL services ranges from 256 kilobits per second (kbit/s) to 24,000 kbit/s, depending on DSL technology, line conditions and service level implemented. Typically, upload speed is lower than download speed for ADSL and equal to download speed for the rarer Symmetric Digital Subscriber Line (SDSL).

The line length limitations from telephone exchange to subscriber are more restrictive for higher data transmission rates. Technologies such as Very high bit-rate Digital Subscriber Line (VDSL) provide very high speed, short-range links as a method of delivering "triple play" services (typically implemented in fiber to the curb network architectures). Technologies like Gigabit Digital Subsriber Line (GDSL) can further increase the data rate of DSL. Fiber Optic technologies exist today that allow the conversion of copper based Integrated Services Digital Network (ISDN), ADSL and DSL over fiber optics.
