How to Wire a DSL Filter

A DSL filter is designed to keep the information being transmitted by your modem and the information being transmitted by your phone separate. This is necessary because both devices use the same phone line at the same times, and digital noise can interfere with your Internet connection without a proper filter installation. These DSL filters can be wired and installed on the phone lines in your home in just a few seconds.

• 1

  Connect the plastic clip on the end of your DSL filter to a phone jack in your wall. This phone jack should be one that is used by a home telephone. If you need to, unplug the telephone's phone cable from the jack so that you can plug in the DSL filter.

• 2

  Insert your telephone's phone cable into the opposite end of the DSL filter. The DSL filter is now installed on your home telephone.

  Repeat "Step 1" and "Step 2" to install a DSL line filter on every other phone jack in your home that is connected to a home telephone. All phone jacks will need to be wired with DSL filters to ensure that your DSL modem is able to transmit information to and from the Internet properly.
