Connecting the Modem to the Internet 7
Manual Setup
Use the topics and procedures below to manually set up your modem.
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.
ADSL Microfilter
Each device such as a telephone, fax machine, answering machine, or caller ID display will require
an ADSL microfilter.
ADSL Microfilter with Built-In Splitter
Use an ADSL microfilter with built-in splitter when there is a single wall outlet which must
provide connectivity for both the modem and telephone equipment.
If you purchased the modem in a country where a microfilter is not included, you must
acquire one.

Do not connect the modem 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 directly to the ADSL line.
