ADSL is the acronym for Asymmetric Digital Subscriber Line, and they are used to enact data transmission at high speed to the internet. Invented by AT&T and adopted by ANSI as standard T1.413 in 1995. Like all DSL broadband technologies, enables a standard telephone line (copper twisted-pair) to simultaneously carry voice and data.
Asymmetric bandwidth is ideal for Internet access because users typically download much more information than they upload. ADSL’s other advantages include: it is always on (you don’t need to “dial up” to the Internet), it works over existing telephone lines, you can talk on the phone and surf the Internet at the same time, and it offers increased security. The actual performance you receive from depends on many factors. See also modem, DSL, G.lite.
