N300 Wireless ADSL2+ Modem Router DGN2200v3
One-Line ADSL Microfilter
Plug the ADSL microfilter into the wall outlet and plug your phone equipment into the jack
labeled Phone. The modem router plugs directly into a separate DSL line. Plugging the
modem router into the phone jack blocks the Internet connection. If you do not have a
separate DSL line for the modem router, the best thing to do is to use an ADSL microfilter
with a built-in splitter (see Two-Line ADSL Microfilter )

If you do not have a separate DSL line for the modem router, the second-best solution 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
Use an ADSL microfilter with a built-in splitter when there is a single wall outlet that provides
connectivity for both the 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 modem router into the jack labeled ADSL.
