Your existing copper telephone lines are made up of different bandwidth channels. The lower bandwidth channel carries your voice communication (telephone), which leaves the higher bandwidth channel available for two-way high-speed data transmission utilizing DSL technology. There is no need for an additional phone line because DSL uses the higher bandwidth channel your telephone doesn’t. Therefore, you can talk on the phone at the same time you are accessing the Internet at DSL Speed!

In order to make DSL work, your digital modem or router at your location accesses the local telephone companies’ central office (CO), where the telephone company has installed a DSLAM that translates your DSL signal. The signal is transmitted from the copper telephone line onto a network backbone, and directed to the DSL aggregation routers. They then verify your access to the network and deliver you to the Internet through a relationship with a backbone network provider.
