N150 Wireless ADSL2+ Modem Router DGN1000
ADSL Microfilters
If this is the first time you have cabled a wireless router 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 N150 Wireless Modem Router on pag
e 14.
An ADSL microfilter is a small in-line device that filte
rs 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. Note that 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 included in the box with the wireless
modem router. If you purchased the wireless modem router in a
country where a microfilter is not included, you have to acquire the
ADSL microfilter separately.
One-Line ADSL Microfilter
To use a one-line ADSL microfilter:
1. Plug the ADSL microfilte
r into the DSL line outlet on the wall.
2. Plug your phone equipment
into the jack labeled Phone.
The wireless 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.
Figure 6. One-line ADSL microfilter
If you do not have a separate DSL line for the router, the best thing to do is to use an ADSL
microfilter with a built-in splitter. See Two-Line ADSL Microfilter on p
age 14. 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.
