3-2 Install a filter on all other phones and phone devices.

Why do I need a filter on all my other phones and phone devices?

Converting your regular phone line into a high-speed Digital Subscriber Line (DSL) can

cause audible noise (high pitched tones and static) when you talk on the phone. You

need to install a filter on every telephone or device that shares the same phone number as

your DSL line to eliminate this noise.

Remember! Don’t install a filter on the data cable that you are

connecting to your DSL modem.
