D6200 WiFi DSL Modem Router
ADSL Microfilters
If this installation is the first time you have cabled a wireless router between an ADSL 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 D6200 WiFi DSL Modem Router on
page 19.
An ADSL microfilter is a small inline device that filters ADSL interference out of standard
phone equipment that shares a line with your
ADSL service. Every telephone device that
connects to a telephone line that provides ADSL service needs an ADSL microfilter to filter
out the ADSL interference. Examples of devices are telephones, fax machines, answering
machines, and caller ID displays. Not every phone line in your home necessarily carries
ADSL service. That depends on the ADSL service setup in your home.
Note: Often the ADSL microfilter is included in the box with the wireless
modem router. If you purchased the WiFi DSL modem router in a
country where a microfilter is not included, you have to acquire the
ADSL microfilter separately.

labeled Phone. The wireless modem router plugs directly into a separate ADSL line. Plugging
the wireless modem router into the phone jack blocks the Internet connection. If you do not
have a separate ADSL line for the router, the best thing to do is to use an ADSL microfilter
with a built-in splitter.

Second best when you do not have a separate ADSL line for the router is to get a separate
splitter. To use a one-line filter with a separate splitter, insert the splitter into the phone outlet,
connect the one-line filter to the splitter, and connect the phone to the filter.
Two-Line ADSL Microfilter (Included)
Use an ADSL microfilter with a built-in splitter when there is a single wall outlet that provides
connectivity for both the WiFi DSL modem router and your telephone equipment. Plug the
