How does DSL work with my phone line?

How DSL works

DSL (Digital Subscriber Line) is a type of broadband Internet connection that utilizes telephone (copper) wires to transmit data at high speeds.

Here is how DSL works:

Telephone lines consist of a pair of copper wires installed in your home by your telephone company. The copper wires have room for carrying much more than just voice conversations. DSL uses this extra room to carry data information on the telephone wire without interfering with your normal phone conversation.

Therefore, you do not need have an additional phone line in order to use DSL Internet service. Nor will you have to limit your phone usage while you are connected to the Internet using DSL. Telephone use and DSL Internet activity can occur simultaneously with no problems.
