ADSL Microfilters
The first time you cable a wireless modem between a DSL phone line and your computer or
laptop, you might not be familiar with ADSL microfilters. If you are, you can skip this section
and proceed to Cable Your Modem Router on page 13.
An ADSL microfilter is a small inline device that filters DSL interference out of standard
phone equipment that shares the same line with your DSL service. Every telephone device
that connects to a telephone line that provides DSL service needs an
ADSL microfilter to
filter out the DSL interference. Example devices are telephones, fax machines, answering
machines, and caller ID displays. Not every phone line in your home necessarily carries DSL
service. The need for DSL service depends on the DSL service setup in your home.
Note: Often the ADSL microfilter is in the box with the modem router. If
you purchased the modem router in a country where a microfilter is
not included, purchase the ADSL microfilter separately.
One-Line ADSL Microfilter
To use a one-line ADSL microfilter:
1. Plug the ADSL microfilter into the DSL line outlet on the wall.
2. Plug your phone equipment into the jack labeled Phone.
The modem router plugs directly into a separate DSL line. If you plug the wireless
modem router into the phone jack, it blocks the Internet connection.

If you do not have a separate DSL line for the modem, the best thing to do is to use an ADSL
microfilter with a built-in splitter. See Two-Line ADSL Microfilter on page 13. You can also
purchase a separate splitter.
To use a separate splitter:
1. Insert the splitter into the phone outlet.
2. Connect the one-line filter to the splitter
.
3. Connect the phone to the filter
.
4. Plug the modem into one of the other outlets in the separate splitter
.
