Newbridge Networks and Stanford Telecom Announce Agreement to Deliver End-to-End Broadband Wireless Solution.

ATLANTA--(BUSINESS WIRE)--June 9, 1998--

Newbridge Agreement Sets the Stage for Continued Joint

Development Efforts

Newbridge Networks (TSE:NNC)(NYSE:NN) and Stanford Telecommunications, Inc. (NASDAQ/NMS:STII) today announced that the companies have signed an agreement, formalizing their long-standing development relationship, whereby Newbridge will integrate modem technology developed by Stanford into its broadband wireless solution.

This agreement broadens the Newbridge(R) end-to-end solution offered to broadband wireless operators using microwave and millimeterwave frequency - such as LMDS (Local Multipoint Distribution Service), MMDS (Microwave/Multichannel, Multipoint Distribution Service) and MVDS (Multipoint Video Distribution System) - to deliver data, Internet traffic, voice, video and multimedia services to business and residential customers. The modulation and demodulation functions performed by the Stanford Telecom components are incorporated into both the Newbridge base-station and customer-premise equipment in the network solution. As well, several Stanford Telecom customer interface units will be fully supported by the Newbridge network solution.

"Newbridge made an early commitment to the development of multi-service delivery solutions for LMDS operators," said Conrad Lewis, Executive Vice President, Marketing and Product Management, Newbridge Networks. "This strategic relationship with Stanford Telecom will provide Newbridge customers worldwide with rapid deployment solutions to take advantage of new spectrum opportunities."

The modem functionality Newbridge is integrating into its broadband wireless solution is based on the TDMA (time division multiple access) technology. TDMA effectively shares bandwidth among a number of users and is optimal for both variable rate connections, where potentially hundreds of Ethernet or other bursty traffic users can share the bandwidth up to wire speeds, and fixed data rate connections (n X T1/E1 or n X 64 kbits/s). Stanford Telecom has developed field-proven solutions for TDMA in the broadband wireless environment, based on its expertise in both military and satellite applications.

Newbridge, in its capacity as an end-to-end solution provider to broadband wireless operators, will benefit from Stanford Telecom's expertise and innovation in modem and customer interface technology, and the opportunity to jointly develop advanced solutions for operators. Stanford Telecom will gain access to a worldwide installed base of Newbridge equipment, and the opportunity to integrate its technology with the industry-leading Newbridge asynchronous transfer mode (ATM) platform.

"Stanford Telecom has enjoyed an excellent development relationship with Newbridge," said Dr. Val P. Peline, President and CEO, Stanford Telecom. "Marrying the strengths of the two companies enables us to offer an optimal solution to operators and immediately address global opportunities."

Stanford's modem technology will be used in the Newbridge broadband wireless solution which is based on the Siemens / Newbridge MainStreetXpress(TM) 36170 Multiservices Switch, the first ATM platform with integrated broadband wireless capability. The Newbridge solution for broadband wireless operators comprises both base-station and customer premise equipment. The ATM radio interface card (ARIC), integral to the MainStreetXpress 36170 Switch, provides an interface between the wire-line backbone and the wireless access portion of the network. The Stanford Telecom modem is integrated into the ARIC. Transmission and reception of the wireless signals is performed by a transmitter/receiver at the base station and a transceiver at the customer premise. Customer interface units provide connectivity to the wire-line network within the customer premise.

Richard Bergen, President, Wireless Broadband Group, Hardin and Associates, a consultancy specializing in wireless communications, commented: "The powerful combination of industry-leading ATM and networking expertise provided by Newbridge, together with Stanford's proven modem technology, provides a compelling solution for broadband wireless operators."

Two broadband wireless networks have been deployed in Canada using the MainStreetXpress platform. WIC Connexus, holder of 47 LMCS spectrum licences across Canada, has deployed a showcase network in Toronto using Newbridge broadband wireless technology. The Ottawa Carleton Research Institute network (OCRInet) has also deployed the Newbridge broadband wireless solution as part of its MainStreetXpress 36170 MultiServices Switch network that serves universities, high-tech companies and research institutes in the Ottawa area.
