How to Install a DSL Filter Correctly So it Will Not Damage

DSL, also called digital subscriber line, is broadband Internet service that uses the copper wiring in the existing phone lines and a special modem to connect you to the Internet. However, phone calls and faxes on the same phone line as your DSL connection can interfere with your Internet service if you do not have DSL filters properly installed. Your DSL connection will be unstable without the filters.

Instructions

1. Unplug any device, such as a fax machine, land-line telephone or a dial-up modem, that is plugged into your DSL phone line.

2. Plug the DSL filters into every phone jack in use, except for the phone jack the DSL modem is plugged into.

3. Plug the phone device into the other end of the DSL filters. Make sure they are plugged in securely. Check the connection by picking up a telephone. If you hear a dial tone you have installed them correctly.
