Zoom ADSL Micro Fliter
- BT Approved The devices filter all telephone set, facsimile machine, answering machines or other analog telephone devices plugged into one of the two 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 & Home Phone line Networks (HPN) from the lower frequencies used by analogue telephone devices, such as a phone. The filters are plugged into all phone jacks in 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.
