How do I install a DSL filter?

If you subscribe to DSL internet service using your telephone line, DSL filters must be plugged into EVERY phone jack that has a phone connected to it. The DSL signal can cause static, noise, squealing (similar to fax tones), caller ID disruption and other issues on your line. DSL filters block the high frequency DSL signals from being transmitted to the telephone.

For most installations, it is recommended that you connect the plug end of the DSL filter into the telephone jack, then connect a telephone line cord between the jack end of the filter and your phone. Please contact your service provider to obtain DSL filters and installation information.
