Zoom Ships New ADSL Gateway with Integrated 4-port Hub

Boston, MA, November 17, 2003 — Zoom Technologies, Inc. (NASDAQ: ZOOM) announced today that it has begun shipping a new ADSL gateway that integrates an ADSL modem, router, NAT firewall, four-port 10/100 Ethernet switch, and USB interface into a single cost-effective product.

The new Zoom ADSL X5, Model 5554 allows a high-speed ADSL connection to be shared by up to 253 concurrent computers on a network, and provides NAT firewall security to protect the attached computers from hackers. The built-in Ethernet four-port switch eliminates the need for a separate hub in most home networks and many small offices, since each port can be used to plug in a computer, a switch, a hub, or a wireless access point. The USB port allows the gateway to be used by a computer that doesn’t have an Ethernet interface, and can be used with the four-port switch to connect up to five computers directly to the X5. With its high performance and flexibility, the X5 is ideal for a home, a school, an office, or almost anywhere you’d like ADSL Internet access for more than one computer.

Setup for the gateway/router features 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.

The X5 is designed to be a product sold through Internet Service Providers and retailers, and features a fast and easy installation process and attractive four-color packaging.

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

The X5 is compatible with computers using an operating system that supports TCP/IP, including Windows, Macintosh and Linux computers.

All Zoom ADSL models are backed by a two-year warranty, European and U.S. multi-lingual support teams, and Zoom’s twenty-six years of experience designing and producing communication products.
