Zoom Technologies Ships Four New ADSL Modems, Including Innovative Residential Gateways
Products Targeted to Retail and Internet Service Provider Markets

Boston, MA, January 16, 2003, - Zoom Telephonics, Inc. (NASDAQ: ZOOM) announced today that it has begun shipping four new ADSL modems designed for easy installation by consumers.

The new products include two residential gateways that combine an ADSL modem with an integrated local area network router. The residential gateways allow a high-speed ADSL connection to be shared by up to 253 computers on a network, and provide firewall security to protect the attached computers from hackers. The Zoom ADSL X3 Model 5560 includes an Ethernet port for connection to a computer, hub, or wireless access point. The Zoom ADSL X4 Model 5551 adds a USB port for connection to a computer's USB port, and allows the USB port and Ethernet port to be active concurrently. Setup for the gateway/router features in both the X3 and X4 is easily done using a Web browser and Zoom's intuitive graphical user interface, facilitating setup by an end-user, a network administrator, or an Internet Service Provider.

In addition to the residential gateways, Zoom is now shipping a PCI internal ADSL modem and a USB external ADSL modem for Windows computers.

The four products are available as retail products, and feature self-install software and attractive four-color packaging. In most cases, the self-install software eliminates the need for a site visit by an ADSL service provider. The first shipments of all four products have been made to Dixon's Store Group, a leading computer retailer in the UK.

The USB model is also available in a self-mailer designed to fit through a mail slot, so that an Internet Service Provider can provide reliable and inexpensive shipment of a unit to a residential customer. The PCI model is also available bulk-packed for use by computer manufacturers and system integrators.

The Zoom ADSL USB Model 5510A modem connects to the USB port of Windows computers for easy installation and setup. The Model 5510A features a compact, space-saving case, and is powered by the USB port to eliminate the clutter created by power adapters. The Model 5510A also has a Point-to-Point protocol stack that runs on the modem to improve system stability.

The ADSL PCI Model 5506 modem is a space-saving internal modem that plugs into the PCI slot of a Windows computer.

All of the new Zoom ADSL products support full-rate Annex A data transmission, with data downloads at up to 8 Mbps speeds. Multi-lingual documentation is in English, French, Spanish, Portuguese, Dutch, and Danish.

All Zoom ADSL models are backed by a two year warranty, European and U.S. multi-lingual support teams, and Zoom's twenty-five years of experience manufacturing communication products for the small office and home office.
