Zoom Announces Next-Generation Modem

Boston, MA, May 24, 1999 -- Zoom Telephonics, Inc. (NASDAQ: ZOOM) in concert with Lucent Technologies Microelectronics Group, has announced it will soon ship a consumer-market modem which supports Digital Subscriber Line (DSL) protocols. Zoom's client-side DSL device will deliver an affordable and flexible transition to high-speed DSL communications by also providing a V.90 56K analog modem on the same PCI-format card. The new Zoom modem is expected to be available by year's end.

Zoom's product will allow data download speeds of up to 1.5 megabits per second and data upload speeds of up to 384K bits per second over ordinary telephone lines using the ITU G.992.2 (G.Lite) protocol. The product is based on the Lucent WildWire™ DSP1690 chip set from Lucent Technologies Microelectronics Group.

"We believe that DSL will be a very high-volume category of product in the near future. Service providers will widely deploy G.Lite DSL and Zoom will be supporting that deployment on the client side with both our Zoom and Hayes brands," said Terry Manning, Vice President of Sales and Marketing for Zoom Telephonics. Zoom recently acquired most of Hayes' modem assets.

"This announcement marks one of the first client DSL offerings in the channel," said Surinder Rai, Lucent's Director of Marketing. "Zoom has been a key partner with us on our 'Lucent Edge' modem campaign and is now taking client side communications to the next level by announcing support for a DSL offering."

Zoom is a leading brand of modems sold through North American distributors, according to PC Data's current Distribution Hardware Report. The Hayes brand is one of the oldest and most respected brands of modems in the world.
