Let’s start by understanding how DSL internet works a little better. Both DSL and old-school dial-up internet use phone lines to connect you to the internet; but dial-up works on a frequency that prevents you from being able to be on the (landline) phone and the internet simultaneously.

DSL stands for Digital Subscriber Line, a technology that transfers data signals using existing telephone infrastructure. In the realm of the Internet and telecommunications, Digital Subscriber Line refers to an early form of broadband Internet connection.

The setup involves a DSL modem at your home to convert digital data for transmission and a DSLAM (Digital Subscriber Line Access Multiplexer) at the internet provider's central office to manage signals and connect you to the network. This configuration allows for "always-on" internet connectivity, making it simple and reliable for daily use.

DSL stands for Digital Subscriber Line, a type of internet connection that uses your existing phone line to deliver higher internet speeds without interruption. What is the difference between Wi-Fi and DSL? DSL is a physical connection that enables your household to access the internet.
