5-pack of ADSL in-line filters which are used to improve the performance of ADSL modems and prevent interference of voice calls in the presence of ADSL modems or Home Phoneline Networking. The devices filter all telephone set facsimile machine answering machines or other analog telephone devices plugged into one of the 2 female RJ-11 ports on the filters. The other female RJ-11 jack is an unfiltered jack which provides a convenient point at which to install an ADSL modem at the same telephone wall jack used for the analog device. The filter isolates the higher frequencies used by ADSL modems from the lower frequencies used by analogue telephone devices such as a phone. The filters are plugged into any phone jack in a home or office where a telephone answering machine fax machine analog modem or other analog telephone device shares a line with an ADSL modem or a Home Phone line Network.
