  Asymmetric Digital Subscriber Line - Wikipedia, the free encyclopedia
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.
Real world performance is also dependent to the line impedance, which can change dynamically either dependent on weather conditions (very common for old overhead lines) or on the number and quality of joints or junctions in a particular cable length.
ADSL technologies use a synchronous framed protocol for data transmission on the wire.

 Broadband Internet access worldwide - Wikipedia, the free encyclopedia
ADSL was successful in Brazil during beta testing, and became popular in 2000, with the main ISPs being Speedy, Ajato and Velox, with typical speeds of around 256 Kbps down and 128 Kbps up.
ADSL appeared commercially in Greece in 2003, and is currently the only broadband standard that exists in the country except for Satellite Internet.
ADSL competition has been low in Sweden, mainly due to the fact that nearly all POTS copper is owned by Skanova (a part of TeliaSonera), who have made it difficult and expensive for third parties to gain access to the telephone stations.

 ADSL Moves into Prime Time
ADSL is ready for prime time and is well positioned to make the transition from moderate-scale rollouts for business customers to widescale mass market deployments.
The ADSL Forum is heading an effort to develop and implement conformance and interoperability test suites for ADSL and for the interoperability between full rate ADSL and Lite ADSL (sometimes identified as splitterless and as Universal ADSL).
ADSL works within the spectrum management guidelines established by the local exchange carriers, which are proceeding with commercial ADSL service rollouts because they know that the broadband technology meets these requirements.

In addition, Telstra has been critisised for limiting their ADSL DSLAM speed to a maximum of 1.5 Mbit and 512 kbit/s (download and upload respectively), whereas the maximum ADSL speed is 8 Mbit and 1 Mbit (download and upload respectively).

ADSL has in theory been available in Italy for a number of years, and has been very widely publicised; but in practice has to now (Sept 2004) been limited by an exasperatingly low technical competence of the telecoms companies, which consumers continue to tolerate.

 Digital Subscriber Line (DSL)
ADSL modems provide data rates consistent with North American T1 1.544 Mbps and European E1 2.048 Mbps digital hierarchies (see Figure 15-2) and can be purchased with various speed ranges and capabilities.
It is becoming increasingly clear that telephone companies around the world are making decisions to include existing twisted-pair loops in their next-generation broadband access networks.
ADSL employs advanced transmission techniques and forward error correction to realize data rates from 1.5 to 9 Mbps over twisted pair, ranging to 18,000 feet; VDSL employs the same advanced transmission techniques and forward error correction to realize data rates from 13 to 55 Mbps over twisted pair, ranging to 4,500 feet.

 ADSL
ADSL can allow users to download digital information at multimegabit speeds while still happily chatting on their analog phone, and all over the same twisted pair copper wire local loop that they used before.
Moreover, ADSL offers a permanent, packet-switched connection for all services, while ISDN supports most of the things ADSL is used for only on traditional circuits (the B channels), which dedicates bandwidth and switching resources to a specific connection for the duration of the connection.
While ADSL shows considerable promise, especially for some flavors of the technology, it remains to be seen if local loop performance limitations will eventually force carriers to abandon ADSL in favor of something else, something that perhaps has not even left the lab yet.

 ADSL
The ADSL technology modifies your telephone line, enabling you to enjoy the benefits of high speed data transfer and a normal telephonic conversation over the same pair of twisted cables.
ADSL is an asymmetric protocol and was originally designed to deliver far more data than a user could send, in fact, it was designed to deliver video signals over a telephone line.
This allows an ADSL modem to directly convert a stream of digital data into a large number of separate analog channels, operating at different frequencies and data rates to take advantage of all the available bandwidth of a telephone line.

 InterOperability Laboratory: Technologies: DSL: Knowledge Base
DSL technology is attractive because it requires little to no upgrading of the existing copper infrastructure that connects nearly all populated locations in the world.
Despite this fact, deployment of new robust and reliable ADSL services is increasingly difficult due, in part, to the physical limitations of the copper telephone system infrastructure, and also in part to the lack of useful ADSL network debugging tools.
ADSL service providers and technicians currently lack a device capable of decoding physical layer signaling and displaying actual physical layer parameters and statistics associated with a live ADSL connection, independent of the end stations.
