What is a DSL Modem?

Let’s start with the basics. DSL stands for Digital Subscriber Line. It is a general term for services that offer Internet connections through phone lines.


There are three types of DSL connections: SDSL, VDSL, and ADSL. A modem is a small box that connects your devices to the Internet using cables. In the case of a DSL modem, the modem is connected to your Internet service provider through a phone line, typically with an Ethernet cable.

How does it work?


Similar to the way landline phones carry signals, broadband lines also allow data from your Internet service provider to be sent via DSL connections. Your DSL modem is the middle man between your Internet service provider and your computer, acting as a data translator that connects your device to the Internet.


Unlike dial-up Internet, which also uses a phone line, DSL allows you to use your phone while connected.

Choosing a Modem


DSL modems are made specifically for DSL connections, so it’s important that you pick a modem that’s compatible with your service. DSL modems can be purchased from many online  or in-store retailers such as Amazon or Best Buy. You may also have the option to purchase or lease a DSL modem through your DSL service provider or telephone company, which ensures you’re getting the right modem for your service.
