Zoom® ITU V.90 FaxModems Now Available in Hong Kong
Zoom Dualmode™ models support both ITU V.90 and K56flex™

Boston MA, March 23, 1998 - Zoom Telephonics (NASDAQ: ZOOM), a leading manufacturer of modems and other data communications equipment, announced today that it has begun high-volume shipments to Hong Kong of ITU V.90-compliant faxmodems with a Dualmode feature that automatically negotiates the connection to allow use with both V.90 and K56flex central sites. Zoom's ITU V.90 faxmodems are distributed by Yutron Tech (Hong Kong) Ltd., which also has offices in Taipei, Tokyo, Singapore, Beijing, and Canton.

"We are introducing the Dualmode products only weeks after the V.90 standard was released by the ITU," said Ron Murphy, Zoom's International Sales Manager. "Hong Kong is a very important market for Zoom Telephonics, and Yutron Tech is a key partner in the growth of this market."

Zoom's 56K products, based on advanced chipsets from Rockwell Semiconductor Systems, have won 10 first-place industry awards for performance and value since their introduction-more than one award per month since August 1997.

The Zoom/FaxModem™ 56K Dualmode has the ability to receive data from ITU International Standard V.90 or K56flex sites at speeds up to 56,000 bps. Dualmode automatically negotiates connections in ITU V.90 mode, K56flex mode, 33.6 Kbps, or any other ITU International or Bell standard speed to achieve the fastest, most reliable connection possible.

All 56K Dualmode models provide high-quality voice mail when used with a soundcard and support both Class 1 and Class 2 fax. They also include V.80 capability, which is required for point-to-point videotelephony using the H.324 Standard, and support H.323 Internet applications including videoconferencing.

All Zoom 56K faxmodems feature a reprogrammable Digital Signal Processor (DSP) and flash memory for easy downloading of upgrades, as well as ZoomGuard™ lightning protection.
