D6300 WiFi DSL Modem Router
connects to a telephone line that provides ADSL service needs an ADSL microfilter to filter
out the ADSL interference. Example 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 modem router in a country
where a microfilter is not included, you have to acquire the ADSL
microfilter separately.
One-Line ADSL Microfilter (Not Included)
Plug the ADSL microfilter into the wall outlet and plug your phone equipment into the jack
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 modem router and your telephone equipment. Plug the ADSL
microfilter into the wall outlet, plug your phone equipment into the jack labeled Phone, and
plug the wireless modem router into the jack labeled ADSL.
