Catapult Extends Leadership in 3G Testing with Support for cdma2000; Availability of cdma2000 Protocols Makes Catapult the Test Solutions Provider of Choice for 3G.

Business Editors/High-Tech Writers

MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--April 9, 2002

Catapult Communications Corporation (Nasdaq: CATT) today announced availability of cdma2000 protocols for its industry-leading DCT2000(TM) Digital Communications Test System. Now shipping, the cdma2000 protocols position Catapult at the forefront of providers of 3G simulation test systems.

With the addition of protocol stacks to test the A, Ater, Aquinter and Aquarter interfaces, Catapult becomes the first company to provide simulation testing solutions for both of the major 3G wireless technologies -- UMTS (Universal Mobile Telecommunications System) and cdma2000 (Code Division Multiple Access). The DCT2000 test system now supports all of the necessary signaling and user traffic connections needed to interface to the cdma2000 core network. Specifically, the DCT2000 now supports the A9 and A11 signaling protocols, the A8 and A10 GRE protocols, and the A1, A3 and A7 IOS protocols.

"The DCT2000 is the test platform of choice for 3G equipment vendors," said Dave Mayfield, COO and president. "For the many companies targeting the 3G marketplace with both cdma2000 and UMTS products, the DCT2000 provides important benefits by supporting both classes of 3G protocols on a single platform. By allowing multiple users to work in parallel and perform different tests simultaneously, the DCT2000 enables telecom companies to get their products to market faster, improve the ROI on their test systems and to optimize their investment in user training and test script development."

With test capabilities for both cdma2000 and UMTS, Catapult is positioned for growth in an important telecom market. It is estimated that CDMA will achieve a market share of at least 25 percent in the wireless telecommunications arena by 2005. The cdma2000 technology is currently being implemented primarily in North America and Asia for remote wireless connectivity between computers and handheld devices, wireless transmission of streaming video, and other high-bandwidth network applications.

The DCT2000 test system -- which provides the broadest range of protocol test modules in the telecom industry -- can be used for complete product lifecycle testing. During the early stages of development, the DCT2000 can be used to test compliance with industry standards and to emulate network equipment that is prohibitively expensive to purchase for test purposes, or not yet available. Later, the DCT2000 can support load testing to measure how much traffic the equipment can handle and monitor traffic flow between network nodes to identify configurations that deliver optimal performance.
