What is DSL?

What is DSL? DSL is a mode of broadband net access carried over conventional phone lines. Like dial-up, it requires its own modem. However, DSL signals cannot be processed through a conventional dial-up modem. DSL delivers speeds comparable to other broadband services, as well as is available in lots of areas nationwide.

How does DSL Work?

How does DSL work? Traditional voice signals travel over phone lines on a very limited frequencies. Local telephone cables, however, can carry signals at frequencies well above and below the frequencies used through voice. DSL takes advantage of these unused frequencies to transmit data. This technology was first used almost two decades ago, but only recently has become important. For less specific information on how DSL works, see "What is DSL?"

Discovery of DSL?
The potential for DSL net service has always existed in the unused frequencies of local phone networks. However, it was not until 1988 that a scientist a Bell Labs developed a method for employing these unused frequencies. At the time, Bell didn't believe that high-speed net access would ever be a consumer product. It sat unused for over a decade; until it became clear it was a valuable tool.

DSL Tutorial
Many people are curious as to where they can get a DSL tutorial. This springs mainly from a fear of being unable to use new technology. However, DSL is, in lots of ways, easier to use than dial-up, because the connection is constant, as well as all you must do to use the service is open your internet browser. Because of this, DSL tutorials are few and far between. The most likely location to get one would be from a potential DSL service provider. A friend or neighbor might also be able to provide an informal DSL tutorial for you, as well as answer other questions you may have related to "What is DSL?"

What does DSL Stand For?
What does DSL stand for? DSL stands for "digital subscriber line." This is to differentiate it from signals over the traditional phone network. Unlike these traditional phone signals, DSL signals only travel from the provider, to the subscriber. Thus the connection is direct. Unlike voice signals, which are analog, a DSL signal is digital, thus the "D" in DSL. For more information, see "What is DSL?"

Learning About DSL
Learning about DSL: There are lots of places to learn about DSL. One resource for answering the question "What is DSL?" could be your local DSL provider. However, they may be more interested in making a sale than imparting knowledge, so be sure to supplement this with other sources. An net search can yield additional results, but be sure they are from a reputable information services webpage. Look for third party WebPages rather than telecommunication companies corporate sites.
