Digital Subscriber Line Essay

Digital Subscriber Line (DSL)

Digital Subscriber Line new technology that takes advantage of standard copper telephone line to provide secure, reliable, high-speed Internet access. DSL refers to the family of digital subscriber line technologies, such as ADSL, HDSL, and RADSL. Connection speed for DSL ranges from 1.44 Mbps to 512 Kbps downstream and around 128 Kbps upstream. Unlike traditional connections DSL such as analog modems and IDSN, DSL deliver continuous “always on” access. That means multimedia-rich websites, e-mail, and other online applications are available anytime. DSL makes it possible for you to remain online even while you’re talking on the telephone-without jeopardizing the quality of either connection. DSL is available

Whether for business or the home, DSL, offers unsurpassed price/performance value compared to other online options. There are the five facts that one should know about DSL. It is remarkably fast. With DSL service, you can benefit from Internet speeds that are up to 12 minutes faster than a typical ISDN connection and 50 times faster than traditional 28.8 Kbps modems. This means that in the 12 seconds it takes to read this information, you could have downloaded a 2 megabyte presentation file or web photograph. It would take 10 more minutes (600 more seconds!) to download the same with a traditional 28.8 Kbps. It’s highly reliable. One can depend on DSL because its proven technology takes full advantage of the existing telecommunications infrastructure. It’s inherently secure. DSL network provides a dedicated Internet connection via private telephone wires, you can bypass dial-up intruders or shared network hackers. Unlike traditional dial-upp modems or cable modems. DSL protects your valuable data with the most secure connection available. It’s surprising affordable. DSL is widely recognized as the most cost-effective connectivity solution for small buisness. DSL delivers industrial- strength like speed to multiple users

This gives you the freedom to focus on what you want to accomplish on line rather than focusing on trying to get connected. In fact, you can be more productive because the power and immediacy of the internet is continuously available at your fingerprints. DSL is a network access technology that telephone companies have been testing and refining since the beginning of the decade. It has unique advantages that it can provide high speed digital transmission over 750 million ordinary phone lines that make up our communication infrastructure. Speed 384 Kbps 128 Kbps 28.8 Kbps 2 Mb image files 72 seconds 3.6 minutes 15.9 minutes 72 MB video 43 minutes 2.2 hours 9.6 ours DSL enables today’s users to gain continuous access to the Internet or corporate Local Area Neworks (LANs) at an amazing rate of 25 times to 100 times faster than the 56.6 kilobits per seconds modems. DSL modems use sophisticated digital coding techniques that squeezes up to 99% or more capacity out of an ordinary phone line, making a super-fast network access possible. DSl was originally developed to support video on demand services that telephone companies planned to offer to compete with cable companies. However most companies have
