What is DSL?
digital subscriber line) Digital subscriber lines carry data at high speeds over standard copper telephone wires. With DSL, data can be delivered at a rate of 1.5 mbps (around 30 times faster than through a 56-kbps modem). Also, DSL users can receive voice and data simultaneously, so small offices can leave computers plugged into the Net without interrupting phone connections. 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. xDSL is the collective term for different variations of DSL, such as ADSL and HDSL.
DSL is a technology that uses a standard copper two-wire pair (or line) to transmit high speed (high frequency) Internet connectivity to areas that will support the service. What are the different DSL types available for Home/Home Office? • Line-share DSL— “Traditional” Asymmetric DSL (ADSL) Available up to 15,000 feet from a CO. Typically the download speed is faster than the upload speed. While ADSL can generally be installed up to 15,000 feet, this general rule does not guarantee that we will be able to install the circuit or that the circuit will perform at a reasonable level (see Terms of Service for more detail). Speed, quality and availability is determined by both distance to CO and copper quality. Speeds expressed with ADSL packages are the maximum speeds your line may achieve. Symmetric DSL (SDSL) is recommended for all eligible businesses. • OneLink™ — Dedicated Line ADSL OneLink™ ADSL does not require phone service, but does require a phone line at the location for the DSL
DSL stands for Digital Subscriber Line, which is not very descriptive. It does not tell you what it is, how it works, or what it does. DSL is like your standard home telephone line. It is a very small electric charge that is sent down two pieces of wire, usually copper. When the phone rings a different type of electric charge is sent through which causes your phone to ring. When you pick up, different electrical charges come in and cause the speaker in your receiver to vibrate in a certain way so you can hear sound come through. DSL takes a large electrical charge and shoots it down the line, creating a digital connection. Your standard telephone is an analog connection with sound, where the digital connection works by sending 0 s and 1 s back and forth to your computer. This is why DSL can run so much faster than a regular modem. It is not dependent on sounds. Sounds have a limitation to what kind of range they can have. Digital is based on numbers, and a “0” is always a “0” and a “1”
DSL (Digital Subscriber Line) is a digital data service offered by New Mexico Technet (beginning September 1999 in Albuquerque, later in other areas) that provides telecommuting capabilities at speeds up to 53 times faster than a standard 28.8 modem. That means you can download data, graphics or audio and video files at high speeds, while simultaneously talking on the phone or sending a fax–and you don’t need additional phone lines to do it.
