Installing DSL filters
The DSL signal is carried over the same lines as the regular phone signal. Converting
your regular phone line to DSL can cause high-pitched tones and static when you use
the phone. To eliminate the noise, install DSL filters on every phone or phone device
that shares the same phone number as the DSL service.
You need one DSL filter for each phone device (such as a desktop phone, analog
modem, Fax, or answering machine). If you have several phone devices connected to
each other and are using a single phone jack, install only one DSL filter between the
phone jack and the first device in the series.
Important:
Do not install a DSL filter on the line that is connected to the DSL gateway.
Installing a DSL inline filter
For most phones, you should install the DSL filter between the device and the phone
jack.
1. Connect the cable from the phone to the DSL filter.
2. Connect the cable from the DSL filter to the phone jack.
