What is DSL?
DSL (Digital Subscriber Line) is a high-speed Internet service that competes with cable Internet to provide online access to local customers. DSL operates over standard copper telephone lines like dial-up service, but is many times faster than dial-up. In addition to being faster than dial-up, DSL does not tie up the phone line, coexisting with telephone service so that one can surf the Net and use the phone at the same time. DSL service requires a DSL modem, which connects to the telephone wall jack and computer. The device acts as a modulator, translating the computer’s digital signals into voltage sent across the telephone lines to a central hub known as a Digital Subscriber Line Access Multiplier (DSLAM, or dee-slam). In lay terms the DSLAM acts as a switchboard for local DSL clients, routing requests and responses between each client’s computer address and the Internet. Voice calls and DSL can coexist on copper lines because each service utilizes its own frequency band. You might
DSL stands for Digital Subscriber Line. DSL is a high-speed Internet service transmitted over ordinary telephone lines. DSL splits a standard phone line into two separate communications channels. One channel is used for voice and one for data. By moving the data channel out of the voice much greater speeds are attainable. Because the voice channel is unaffected by the addition of the DSL data channel; any features on your phone like voicemail or caller-id continue to work like always. In addition to superior performance and reliability you get an “always on” connection to the Internet.
