ADSL is a new telephone line technology that allows high bandwidth data connections to be made over existing copper pair telephone lines, typically 40 times faster than current modem technologies. ATM
A method for moving data over regular phone lines. An ADSL circuit is much faster than a regular phone connection, and the wires coming into the subscriber’s premises are the same wires used for regular phone service. An ADSL circuit must be configured to connect two specific locations, similar to a leased line. A commonly discussed configuration of ADSL would allow a subscriber to receive data at speeds of up to 1.544 megabits per second,and to send data at speeds of 128 kilobits per second.
A high-speed technology that allows large volumes of data to be sent over a telephone line. ADSL allows data rates of 1.5 to 9 Mbps when receiving data and from 16 to 640 Kbps when sending data.
A transmission technology that transmits an asymmetric digital signal using one of a variety of line codes as specified in the ANSI standard. ADSL technology enables data transmission over existing copper wiring at data rates several hundred times faster than analog modems, providing for simultaneous delivery of voice, video and data.
Asymmetric Digital Subscriber Line ( ADSL) is a form of DSL, a data communications technology that enables faster data transmission over copper telephone lines than a conventional modem can provide. ADSL has the distinguishing characteristic that the data can flow faster in one direction than the other ( i.e., asymmetrically). Providers usually market ADSL as a service for people to connect to the Internet in a relatively passive mode: able to use the higher speed direction for the "download" from the Internet but not needing to run servers that would require bandwidth in the other direction or "upload". See Also: Digital Subscriber Line
A copper-based access technology that allows cable TV, video, telephony, and other multimedia services to be carried over a single twisted-pair cable that can carry from 1.5M to 8M bps downstream, and between 16K and 450K bps upstream. This technology is designed to operate over distances from 2 km. to 6 km. without the use of repeaters, depending on the quality of the twisted-pair cable and the bit rate being carried.
Digital technology to allow broadband service over ordinary copper telephone lines. Transmission capacity is greater from network to customer (c1.5Mbps) than customer to network, hence asymmetric.
ADSL is the most popular form of DSL technology which typically emphasizes high bandwidth downstream (e.g. up to 6.144Mbps) and lower bandwidth upstream (e.g. 640kbps)
or "ADSL" a technology which allows high speed data communication through the same copper lines
A version of digital subscriber line technology with a range of 18,000 feet that transmits over a single copper twisted pair cable at upstream rates of 16 to 640 Kbps and downstream rates of 1.5 to 9 Mbps.
System that uses digital filtering to eliminate noise from copper lines to allow broadband transmission. There are various types of ADSL.
Also referred to as ADSL Full Rate or G.992.1. Physical layer protocol supporting up to 8 Mbps bandwidth downstream, and up to 1 Mbps upstream. Good for video on demand, internet browsing, and remote LAN access. Base range is 18,000 feet, extendable via ADSL repeaters up to 48,000 feet (or more using fiber optic)
A technology in which high-capacity transmission requirements, such as compressed video signals are delivered through copper wire. In this case, "asymmetric" refers to the transmission capacity toward the customer being greater than that from the customer to the network.
This is a new technology that the telecommunications company's answer to cable modems. It supports data speeds over 2 Mbps downstream (to the user) and slower speeds upstream (to the Internet). This technology should eventually supplant ISDN if it achieves a reasonable price point.
a technology that allows the use of a copper line to send a large quantity of data (eg a television picture) in one direction and a small quantity (eg a control channel and a telephone call) in the other
The variation on DSL that is used for Internet access. It increases modem speeds by a factor of 30. Requires no change to existing wiring. From CNet: "Like ISDN, ADSL uses standard phone lines to deliver high-speed data communications. But while ISDN's transmission speed is limited to 64 kbps, ADSL technology can deliver upstream (from the user) speeds of 640 kbps and downstream (to the user) speeds of more than 6 mbps. Even better, ADSL uses the portion of a phone line's bandwidth not utilized by voice, allowing for simultaneous voice and data transmission."
enabling faster Internet access and the Internet to be online 24 hours a day as well as phone access.
ADSL allows very high-speed data movement over regular copper telephone lines. The term is "asymmetric" because the speeds going INTO your house or business are much greater than the speeds sent from you back up the line. Operating in this "unbalanced" way makes sense because the large files requiring a lot of speed and bandwidth are coming TO your computer screen, while all that's being sent back from you is a relatively small amount of data -- the signal you send back down the line when you click your mouse or type on your keyboard.
A very high speed data transfer technology which uses standard telephone lines.
ADSL is becoming the alternative to an ISDN line. It allows much higher bandwidths over a standard digital telephone line. It needs to be configured similar to a leased line in such a way that it can connect only to ISPs that are near you. A typical ADSL setup allows download speeds up to 1.5 megabits per second (about 200 kilobits per seconds), but upload is restricted to 128 kilobits per second (similar to two ISDN lines). ADSL works asynchronously, therefore the different up- and download speeds. See also bit, bps, ISDN, leased line, {\em xDSL.
A technology for transmitting digital information at a high bandwidth on existing phone lines to homes and businesses.
This is a technology used for access to the internet. ADSL will let us download information quickly and upload data at a slower rate. ADSL is suitable for web browsing where we want to download pages to our computer but upload infrequently. E-speed uses ADSL technology. Users may use a single telephone line for both data and voice communication. ADSL access is much faster than modem access. It also has the advantage that the same telephone line can be used for both talking and internet at the same time.
See ADSL.
An evolving high-speed transmission technology that allows more data to be sent over existing copper telephone lines (POTS). ADSL supports data rates of from 1.5 to 9 Mbps when receiving data (known as the downstream rate) and from 16 to 640 Kbps when sending data (known as the upstream rate). ADSL requires a special ADSL modem. It is currently available to the general public in a few trial areas, but many believe that it will be one of the more popular choices for Internet access over the next few years. The ITU is currently defining an xDSL standard based on ADSL, called G.dmt.
fast digital connection to your telephone exchange. ‘Asymmetric’ because data downloading is faster than uploading.
A technology that provides high-speed data on an asymmetric basis. Typically a copper line is used to send a large quantity of data (eg a television picture) in one direction and a small quantity (eg a control channel and a telephone call) in the other. Currently used for speeds of up to 2 Mb/s.
A technology that is the phone company's answer to cable modems. It supports data speeds over 7Mbps downstream (to the user) and slower speeds upstream...
Also referred to as Digital Subscriber Line (DSL), ADSL 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.
(ADSL) ADSL is a technology for transmitting digital information at a high bandwidth on existing telephone lines. Unlike a regular dial-up telephone service, ADSL provides an "always on" connection. ADSL is asymmetric in that it uses most of the channel to transmit downstream to the user and only a small part to receive information from the user. ADSL simultaneously accommodates analogue (voice) information on the same line. See also Digital Subscriber Line (DSL).
ADSL is a data communications technology that can “piggyback†a standard voice telephone connection and a high-speed (up to 8Mbps) digital data link on to a single pair local loop connections to a customer premises. ADSL technology is an asymmetric technology, meaning that the speed of the digital link to a customer premises is generally not the same speed as the connection coming back. With ADSL, for example, a customer may have only 128Kbps of outbound bandwidth, but may be able to receive data at speeds of 8Mbps. See DSLAM, NID, and xDSL.
Form of digital subscriber line service commonly deployed for commercial and residential users, designed mainly for World Wide Web use. Downstream data rates are significantly faster than upstream rates.
A high-bandwidth digital transmission technology that uses existing phone lines and also allows voice transmissions over the same lines. Most of the traffic is transmitted downstream to the user, generally at rates of 512 Kbps to about 6 Mbps.
Asymmetric Digital Subscriber Line (ADSL) is a form of DSL, a data communications technology that enables faster data transmission over copper telephone lines than a conventional voiceband modem can provide. It does this by utilizing frequencies that are normally not used by a voice telephone call, in particular, frequencies higher than normal human hearing. This signal will not travel very far over normal telephone cables, so ADSL can only be used over short distances, typically less than 5 km.
