DSL High Speed Internet Service, T1 and OC3 Information (DSL)
DSL Service (digital subscriber line) is a proven technology that uses standard telephone lines to provide reliable, high-speed Internet access for business and home (Business DSL and residential DSL). DSL service is "always-on," providing DSL high-speed Internet connectivity for websites, e-mail and other online applications.
DSL service and similar technologies have deep roots in the advanced analog (dial-up) transmission techniques developed over the years to improve the data rate over ordinary phone lines using modems. This provides high rates of speed for DSL Internet access. Furthermore, DSL service is built on techniques to take advantage of low-cost digital signal processors to further improve the available DSL bit rates and DSL transmission reliability across an ordinary pair of twisted copper wires.
Over the years, these DSL advances have made it possible to support data rates of not Kbps, but Mbps. This DSL digital service can be used to deliver bandwidth-intensive applications like streaming audio / video, online games, application programs, telephone calling, video conferencing and other DSL high-bandwidth services. Today, DSL service is putting high-speed Internet access within the reach of the home (residential DSL), small and medium-size businesses (Business DSL). DSL service takes existing voice cables that connect customer premises to the phone company's central office (CO) and turns them into high-speed DSL Internet Access.
DSL has many benefits over analog modems with high-speed topping the list. Unlike the dial-up connections required for analog modems, your DSL connection is always on. That means no more logging on and off, no more busy signals and no more waiting for the connection to happen—it is always there. Another benefit is the ability to use the phone at the same time the data connection is on; you don't have to choose between the two.
