  Digital Subscriber Line - Wikipedia, the free encyclopedia
DSL is the principal competition of cable modems for providing high speed Internet access to home consumers in Europe and North America.
DSL takes advantage of this unused bandwidth of the local loop by creating 4312.5 Hz wide channels starting between 10 and 100 kHz, depending on how the system is configured.
The commercial success of DSL and similar technologies largely reflects the fact that in recent decades, while electronics have been getting faster and cheaper, the cost of digging trenches in the ground for new cables (copper or fiber) remains expensive.

 Howstuffworks "How DSL Works"
DSL is a very high-speed connection that uses the same wires as a regular telephone line.
DSL doesn't necessarily require new wiring; it can use the phone line you already have.
A DSL connection works better when you are closer to the provider's central office.

 Fast Guide to DSL - a Whatis.com definition - see also: DSL, xDSL, DSL Guide, Digital Subscriber Line
DSL (Digital Subscriber Line) is a technology for bringing high-bandwidth information to homes and small businesses over ordinary copper telephone lines.
DSL is expected to replace ISDN in many areas and to compete with the cable modem in bringing multimedia and 3-D to homes and small businesses.
DSL is now offered in most parts of the United States, in the UK, and elsewhere.

 Domain-Specific Languages: An Annotated Bibliography1
In many cases, DSL programs are translated to calls to a common subroutine library and the DSL can be viewed as a means to hide the details of that library.
DSLs allow solutions to be expressed in the idiom and at the level of abstraction of the problem domain.
The major reason to design a DSL (as opposed to using a library) were the traversal patterns that cannot be captured in a library.

 xDSL Technology   (Site not responding. Last check: 2007-11-02)
DSL modems, on the other hand, establish a connection from one end of a copper wire to the other end of that copper wire: the signal does not pass into the telephone switching system.
The data frequencies are wired into a corresponding DSL modem at the CO end and the resulting high-speed digital data stream coming from (or going to) the consumer is then handled as normal data (not analog voice) and may be hooked into any number of networking technologies for further connection to the data's destination.
DSL Sourcebook is a detailed treatment of DSL, with a particularly good discussion of the network layers used to provision DSL (and the use of ATM as the popular backbone of choice for DSL).

 DSL - Glossary - CNET.com   (Site not responding. Last check: 2007-11-02)
With DSL, data can be delivered at a rate of 1.5 mbps (around 30 times faster than through a 56-kbps modem).
Currently, DSL is expensive because specialized equipment--a splitter--needs to be installed at the subscriber's location.
DSL Lite, the consumer-ready version of DSL, requires no such splitter, and promises comparable access speeds at a cheaper rate.

The basic idea of a domain specific language (DSL) is a computer language that's targeted to a particular kind of problem, rather than a general purpose language that's aimed at any kind of software problem.
One community that uses DSLs a lot is the Unix community where they are often referred to as little languages or mini languages.
The pragmatic programmers have long been fans of DSLs, primarily from the Unix tradition (there is an excellent discussion in section 12 of The Pragmatic Programmer - perhaps I should call that Pragmaticum 12).

DSL and ISDN are different transmission technologies, yet both offer many of the same higher speed benefits to consumers.
DSL is an always-on service while ISDN requires dialing into a service provider's network.
If DSL transmission technology is not available in your area, ISDN may serve as an acceptable substitute for use in providing high-speed Internet access.
