HONG KONG, CHINA--(BUSINESS WIRE)--March 2, 1999-- NEWBRIDGE(TSE:NNC.) (NYSE:NN) Networking Solution Enables Delivery of Value-Added Converged Voice and Data Services.

Newbridge Networks (NYSE: NN; TSE: NNC) today announced that Zhengzhou telecommunications Bureau (Zhengzhou Telecom), a service provider that offers a wide range of voice and data services, including local, long distance and mobile telephony and integrated services digital network (ISDN) to approximately six million customers, has selected Newbridge to expand and upgrade its digital data network (DDN). The significant network expansion will enable Zhengzhou Telecom, which provides telecommunications services to one of the most populous cities in Henan province, to respond to rapidly growing customer demand for value-added, integrated voice and data services. The agreement to provide the networking solution was completed through Vodatel Systems, a Newbridge(r) distributor, based in the People's Republic of China.

Since its installation in 1994, the Zhengzhou DDN network has faced explosive demand to support advanced voice and data services. As such, Zhengzhou Telecom was seeking a flexible networking solution to support this explosive growth now and well into the future.

Zhengzhou selected the Newbridge solution because of its high scalability, reliability and the unmatched network and service management capabilities provided by the Siemens / Newbridge MainStreetXpress(tm) 46020 Network Manager.

"The superior network and service management capabilities provided by Newbridge and the ease with which service providers can expand their networks and migrate simply to a multiservice, multi-access, asynchronous transfer mode (ATM) platform were key factors in Zhengzhou's decision to select Newbridge Networks," said Roger Fung, Executive Vice President, Asia, Newbridge Networks.

These superior network and service management capabilities, will enable Zhengzhou Telecom to protect its initial network investment and expand its network to quickly and effectively meet the diverse needs of its customers.
