A DSL modem modulates high-frequency tones for transmission to a digital subscriber line access multiplexer (DSLAM), and receives and demodulates them from the DSLAM. It serves fundamentally the same purpose as the voice-band modem that was a mainstay in the late 20th century, but differs from it in important ways.
Asymmetric digital subscriber line (ADSL) is a type of digital subscriber line (DSL) technology, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. ADSL differs from the less common symmetric digital subscriber line (SDSL).
Digital subscriber line (DSL; originally digital subscriber loop) is a family of technologies that are used to transmit digital data over telephone lines. [1] In telecommunications marketing, the term DSL is widely understood to mean asymmetric digital subscriber line (ADSL), the most commonly installed DSL technology, for Internet access.
Different terms are used for broadband modems, because they frequently contain more than just a modulation/demodulation component. Because high-speed connections are frequently used by multiple computers at once, many broadband modems do not have direct (e.g. USB) PC connections. Rather they connect over a network such as Ethernet or Wi-Fi.
The term “broadband” refers to a high-speed internet connection that uses a satellite, digital subscriber line or cable connection for data transmission. A broadband connection is usually a lot faster than a dial-up connection and allows you to browse the web and download videos, music and games much more quickly.
Fixed broadband subscriptions (per 100 people) In telecommunications, broadband or high speed is the wide-bandwidth data transmission that exploits signals at a wide spread of frequencies or several different simultaneous frequencies, and is used in fast Internet access.
Very-high-bit-rate digital subscriber line (VDSL or VHDSL, ITU G.993.1) [61] is a digital subscriber line (DSL) standard approved in 2001 that provides data rates up to 52 Mbit/s downstream and 16 Mbit/s upstream over copper wires [62] and up to 85 Mbit/s down- and upstream on coaxial cable. [63]
