Understanding ADSL Microfilters

ADSL technology uses the same wires as your telephone service. However, ADSL adds signals to
the telephone lines which create noise in the telephone service. You must use ADSL microfilters to
filter out these signals before they reach your telephone.
Note: If you purchased the modem router in a country where a microfilter is not included,
you must acquire one.

Each device such as a telephone, fax machine, answering machine, or caller ID display will require
an ADSL microfilter.
Warning: Do not connect the modem router to the ADSL line through a microfilter
unless the microfilter is a combination microfilter/splitter specifically
designed for this purpose. Doing so will prevent block your connection to the
Internet. If you have any doubts about this, connect the modem router directly
to the ADSL line.
