Most high-speed Internet providers assemble their online packages with the expectation that customers want many services with the greatest convenience. Or, at least, they see your need to upgrade to a faster Internet connection as an opportunity to get you to sign up for every service that they offer.
With more and more people using cell phones as their primary phone line, DSL Internet providers have created a new technology to allow consumers to use DSL Internet service without a phone line. This service is known as “dry loop” DSL, and runs through existing phones wires. You do not need to subscribe to phone line service to use it.
DSL technology dates back to 1948, to research by Claude Shannon, but it wasn’t really invented until 1988 by Joseph Lechleider and other employees of Bellcore. By the late 1990s, DSL technology had grown to the point that it was faster and easier to provide, allowing for more home users to have access to it.
DSL is a high-speed way of connecting computers to the Internet through the telephone lines. Since a typical telephone line sends an analog signal, DSL sends information through a digital signal, which frees the telephone line to send and receive phone calls while the computer is connected to the Internet. Different phone companies offer DSL through their phone services.
DSL basically, it works by halving the phone line whereby the line with high frequency is made available for your connecting to the web while the other line remains for your telephone. There are other ways to access the Internet aside from DSL and one is through a cable connection. The problem is, when something’s wrong with your Internet cable, you can’t use your cable TV as well. However, with DSL, your phone line will always work separately from your Internet line which means you can use either or both and damage to one won’t necessarily mean damage to the other.
The main selling point of a DSL connection is its high speed. It, in fact, offers one of the fastest Internet connections these days. However, aside from that, it also promotes file security with its feature that allows it to be set up or configured without being networked with the other PC’s in the office, for example.
Different service providers offer DSL, including AT&T, Verizon, and EarthLink. The difference between these services is the extra options each can provide, such as varying speeds, the ability to have DSL without paying for telephone service, and bundle packaging including deals for telephone service. With DSL technology, there is the standard DSL and “naked” DSL. Naked DSL is simply the option of having DSL without a landline telephone service.
