A general term for any local network loop that is digital in nature; See ADSL, HDSL, SDSL, VDSL, xDSL.
A technology that allows a provider to use the excess bandwidth found in a copper line for the provision of data services. While this technology was meant to make use of an enormous copper infrastructure until fiber optic cable was fully deployed, it has become an industry unto itself. xDSL is used to describe all of the "flavors" of DSL in general.
A form of high-speed Internet access currently competing with cable modems. DSL works over standard copper phone lines. In fact, most DSL service is limited...
DSL is a high-speed connection over telephone lines. Speeds can be as high as 1.5 Mbps (megabits per second). DSL is an always-on connection that runs over normal phone lines, so that there is no need to dial up or login.
a high-speed method of data transfer over existing telephone lines, which is considerably faster than standard modem connections. DSL speed varies considerably depending on the service purchased.
Xdsl refers collectively to all types of igital ubscriber ines, the two main categories being ADSL and SDSL. Two other types of xDSL technologies are High-data-rate DSL (HDSL) and Symmetric DSL (SDSL). DSL technologies use sophisticated modulation schemes to pack data onto copper wires. They are sometimes referred to as last-mile technologies because they are used only for connections from a telephone switching station to a home or office, not between switching stations. xDSL is similar to ISDN inasmuch as both operate over existing copper telephone lines ( POTS) and both require the short runs to a central telephone office (usually less than 20,000 feet).
A generic name for a group of enhanced speed digital services provided by telephone service providers. DSL services run on twisted-pair wires; they carry both voice and data. Learn more.

Digital subscriber line is the transmission of digital information, usual on a copper wire pair. Although the transmitted information is in digital form, the transmission medium is usual an analog carrier signal (or the combination of many analog carrier signals) that is modulated by the digital information signal.
Broadband connection available to commercial or private subscribers, generally offered by local telephone companies. DSL typically refers to a connection offered on ordinary copper line that offers transmission speeds at about 6 Mbps downstream, bundling voice, data and Internet services on the same line. The term is sometimes used to refer to the ?next generation? of network connections beyond ISDN. Sometimes, ?xDSL? is used by a to refer to any of a number of emerging DSL technologies (symmetric, meaning same speeds up- and downstream, or asymmetric, referring to faster downstream speeds than upstream speeds). DSL services are limited with within about 12,000 feet of a telephone company?s central office.

Digital lines that telecommunication utilities provide to their local customers for both voice and data (e.g., computer and fax machines) over the same telephone line.
Also referred to as Asymmetric Digital Subscriber Line (ADSL) , DSL is a technology that enables data transmissions over existing copper wiring at data rates several hundred times faster than today's analog modems. ADSL was specifically developed for the simultaneous delivery of voice, video, and data to the home, which requires a higher downstream bandwidth than upstream bandwidth. Downstream ADSL data rates are as high as 8 Mbps, while upstream data rates can reach 1 Mbps. Fully symmetric data rates of up to 1 Mbps are also possible.
A highspeed broadband connection that uses the unused frequencies of a phone line. Maximum speeds are dependent on the length of wire between the DSL modem and telephone switching office.
A generic name for a family of digital lines (also called xDSL) provided by CLECs and local telephone companies to their local subscribers. Such services propose to give the subscriber up to eight million bits per second one way, downstream to the customer and somewhat fewer bits per second upstream to the phone company. See ADSL for more detailed information.

A technology that allows the use of a copper line to send higher bandwidth services, such as fast internet and video, to a customer's premises.
A DSL line is an ordinary telephone wire used for digital data. DSL circuits are faster than conventional analog modems. Two common types of DSL are ADSL (Asymmetric DSL -- fast downloading, slow uploading -- less expensive and commonly used for consumer applications) and SDSL (Symmetric DSL -- fast communication in both directions, used for connecting server computers to the Internet. At the customer's end of the wire, a device named a DSL router is required (sometimes incorrectly called a DSL modem.) The computers and access points connect to the router.
A type of high-speed Internet connection. Digital Subscriber Lines (DSL) are sophisticated technology that enables data to be "packed" and sent over regular telephone wires. Unfortunately, the technology is not available to everyone because the packed data breaks up if it must travel more than about 20,000 feet between a home or office to the telephone switching station. Consequently, DSL is not available in all areas.
A super fast, fairly reliable connection to the Internet that uses an existing phone line, without interruption to regular telephone service. The speed of your connection will vary depending on the plan you purchase; the minimum is much faster than a dial-up. Domain: is the name for an organization on the internet. The domain is usually made up of two parts - the name and the type - red.net, microsoft.com, ins.org, ucf.edu, etc... In country hierarchies, the domain can have more parts - each country sets its own rules. Domain Name System (DNS): Dist ributed name/address database used on the internet. back to the top E-mail (electronic mail): The transmission of memos and messages to a single recipient or to multiple users all around the world.
A digital subscriber line (DSL) transmits electronic data over regular copper-wire phone networks, making use of high-frequency bands not used in conventional telephone services. One type of DSL, known as an asymmetric digital subscriber line (ADSL), is capable of downloading data some 10 times faster than the popular ISDN (integrated services digital network) lines offered by Nippon Telegraph and Telephone Corp. DSL services require special equipment to be installed at the telephone company and the subscriber's home or business. They have grown to become a major form of Internet connection in the U.S. and South Korea, although throughput is slower than with advanced fiber-optic services. There were 291,333 DSL subscribers in Japan at the end of June 2001, compared with less than 10,000 a half year earlier, according to a survey released in July 2001 by the Ministry of Telecommunications.
See DSL.

The most common type of broadband connection, which uses existing telephone wires to carry the connection into the home, thus eliminating the need for expensive rewiring.
DSL enables high-speed voice, video, and data connections over the regular copper phone wires that connect most homes and businesses to the larger telecom network. DSL is the technology most local telecom companies are relying on to offer bundled, high-speed services and compete with alternate carriers, such as cable and satellite companies. See also ADSL.
A method for moving data over regular phone lines. A DSL circuit is much faster than a regular phone connection, and the wires coming into the subscriber's premises are the same (copper) wires used for regular phone service. A DSL circuit must be configured to connect two specific locations, similar to a leased line (however a DSL circuit is not a leased line).
is a high-speed data service provided by your telephone company over high-quality copper telephone wire. DSL transmits data at speeds far greater than standard phone service.
SDSL. Two other types of xDSL technologies are High-data-rate DSL (HDSL) and Very high DSL (VDSL). DSL technologies use sophisticated modulation schemes to pack data onto copper wires. They are sometimes referred to as last-mile technologies because they are used only for connections from a telephone switching station to a home or office, not between switching stations. xDSL is similar to ISDN inasmuch as both operate over existing copper telephone lines (POTS) and both require the short runs to a central telephone office (usually less than 20,000 feet). However, xDSL offers much higher speeds - up to 32 Mbps for upstream traffic, and from 32 Kbps to over 1 Mbps for downstream traffic.
See Asymmetric Digital Subscriber Line
