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. If you purchased the modem router in a country where a microfilter is not included, you must acquire one.
