Zoom USB Cable Modem Earns CableLabs Certification
Zoom among first to offer full range of certified cable modems

Boston, MA, December 15th, 2000 -- Zoom Telephonics Inc. (NASDAQ: ZOOM) a leading supplier of Internet access products, today announced that its external USB cable modem has received CableLabs certification. Zoom's Ethernet and PCI models were certified in late July of this year.

Zoom is now one of only two companies offering CableLabs certified cable modems in all three popular formats, which makes Zoom a one-stop source for service providers, computer manufacturers and retailers. Unlike the other company, Zoom has strong brand names worldwide and a team of field application engineers and technical support professionals based in the USA.

The Zoom CableModem USB simply plugs into the USB port of a computer and provides professional installers and consumers with the easiest installation possible. Cable modems with an Ethernet interface often require the installation of a network interface card, and internal cable modems require opening of the computer case. "For anyone looking for a fast and easy installation, USB is the answer," said Dean Panagopoulos, Vice President of Network Products, Zoom Telephonics.

The Zoom CableModem USB is a significantly less expensive external solution than the combination of an Ethernet card and Ethernet cable modem.

The Zoom CableModem USB is compatible with desktop and laptop computers using Windows 98, 2000 and Me operating systems. A Macintosh-compatible version is expected to be released soon.

Zoom's complete cable modem line complements the company's other new offerings in ADSL modems and wireless local area networking. Residential gateway products which distribute broadband data through local area networks within homes and small business are expected early next year.
