Zoom® PCI Cable Modem Earns Microsoft WHQL Certification

Boston, MA, November 3, 2000 -- Zoom Telephonics Inc. (NASDAQ: ZOOM), today announced that the Zoom CableModem PCI has earned unqualified Microsoft Windows Hardware Quality Labs (WHQL) approval. The approval is the first given to a production model of an internal cable modem. This means that Zoom Telephonics makes the only internal cable modem that has both WHQL approval and CableLabs® Certification.

The Zoom PCI cable modem is one of only two internal cable modems to be CableLabs Certified. CableLabs called its certification of these two internal PCI cable modems "a major breakthrough."

Passing the stringent WHQL tests is important for a number of reasons. The certification allows the Zoom product to display the "Designed for Windows® Me, Windows® 98 and Windows® 2000 Professional" logos on retail packages. The logos assure customers easy plug-and-play installation when used with Windows operating systems. The WHQL certification also means the Zoom cable modem may be integrated into computers by manufacturers seeking the valuable and highly marketable "Designed for Windows" logo for their overall systems. Finally, some major service providers require WHQL certification for internal cable modems they market.

CableLabs® (Cable Television Laboratories, Inc.) is a non-profit research and development consortium of cable television system operators representing North and South America. CableLabs® certification ensures compliance with the cable industry's strict performance and interoperability standards known as DOCSIS (Data Over Cable Service Interface Specification).

"We are very pleased to be the first cable modem manufacturer to offer a Microsoft WHQL approved cable modem product," said Frank Manning, President of Zoom Telephonics. "This certification facilitates integration of broadband communications into Windows-based systems, including Windows-based set top devices. The certification also emphasizes Zoom's commitment to the cable industry, and our support for cable modems used in a broad range of installations and applications."
