What is DSL?
DSL (Digital Subscriber Line) is a technology that allows DIRECTV DSL to provide you with high-speed internet access over ordinary copper phone lines. We provide two types of DSL; SDSL (Symmetric Digital Subscriber Line) and ADSL (Asymmetric Digital Subscriber Line) and each requires a different type of phone line. The type you get depends on what’s available in the area where you live. Current advances in DSL technology include wireless DSL. DIRECTV DSL does not currently provide wireless DSL. SDSL SDSL (Symmetric Digital Subscriber Line) uses a dry copper phone line to connect to the Internet; a dry copper line cannot carry voice calls. With SDSL, uploading to the Internet (which you do when you send email) occurs at the same speed as downloading, which is what you do when you surf. With a SDSL connection from DIRECTV DSL , however, we optimize your download speed since that’s what subscribers will be doing most often. ADSL ADSL (Asymmetric Digital Subscriber Line) lets you use the s
DSL stands for Digital Subscriber Line. Often, DSL is proceeded by one of the letters “A, S, H, or x”. These letters describe the kind of DSL in use, with “ADSL” corresponding to the majority of residential DSL installations and “SDSL” describing a method of DSL that many businesses use. “xDSL” is used to describe DSL in generic terms. DSL technology involves equipment located outside the home or office, the actual phone lines in your home or office and a modem or similar device connected to your computer or network of computers. DSL Modems help to convert the signals from your computer to travel on the same copper lines that carry regular voice telephone service. Many ADSL installations involve regular voice and high-speed data traveling on the same copper phone line, often at the same time. To accomplish this, digital signal processors in the modem suppress the noise created when high-speed data is crammed down a standard copper-wire phone line. DSL Modems can deliver Internet access
DSL (Digital Subscriber Line) Internet access provides very high-speed connections by sending digital signals over your existing phone line. A DSL connection uses a special modem to split the digital and analog signals on your phone line and routes them to the local phone company’s central office, from which you are connected to the Internet. Digital signals can transmit much more data, much faster, than an analog dial-up signal.
