ADSL Filters


AFT-1 is the world’s best ADSL filter created to provide crystal clear voice conversation for PSTN alarms by preventing broadband signals and static from interfering with facilities using landlines such as telephones and fax machines. This kind of interference frequently happens when an ADSL modem uses a POTS phone line for internet connections. Easy-to-install AFT-1 with RJ-11 ports eliminates telephone lines’ background noise and optimizes the DSL signal.
