With models for a variety of U.S. and international phone configurations, the Z-BLOCKER line is the choice of telecom carriers, ISPs and consumers worldwide. Since their introduction in April 1999, their performance, value, reliability and easy installation have made them the top-selling phone filters in the U.S. and around the world.

Complementing the phone filters, we also offer products to provide broadband Internet access to office buildings, hotels, apartment complexes and other multi-tenant units (MTUs). As a contributing member of the Home Phoneline Networking Alliance (HomePNA), we offer products to bring the power of high-speed data networks to homes and small offices.
