-- Initial West Coast networks to be completed in the first quarter, 2000 --

ATLANTA, GA, December 2, 1999 - Hitachi Telecom (USA), Inc., today announced that US Optics, Inc., based in Los Angeles, California, will deploy Hitachi's AMN (Advanced Multiservices Network) ultra high speed optical transmission equipment, including DWDM (Dense Wavelength Division Multiplexing) and OC-192 SONET (Synchronous Optical Network) equipment, in its West Coast network.

US Optics will operate the network over the optical fiber facilities of participating utility companies. The initial deployments will be four-fiber bi-directional line-switched rings (BLSR) in the Bay Area of San Francisco and in Los Angeles. US Optics plans to expand to a nationwide backbone connecting eleven other cities within the next two years. The agreement between US Optics and Hitachi is valued at $100 million over a three-year term.

"I believe that the future need for bandwidth lies within the metropolitan areas. US Optics is gearing itself to establish WDM environments within these metro areas and interconnecting them into a nationwide backbone network," stated Robert Bral, president of US Optics.

"Hitachi is pleased to have been selected by US Optics as the supplier for this unique solution to the bandwidth demand on the West Coast," stated Don Boriskie, Hitachi's vice president of sales. "Our superior technology and our track record for delivering on time with the performance promised will be an asset to the US Optics Network."

About Hitachi's Advanced Multiservices Network Product Family

Hitachi's AMN family of advanced optical networking products is designed to provide carriers with ultra high bandwidth, flexible transport solutions whether the application is SONET, IP, ATM or any other communications protocol. Operating under a single element management system for maximum control efficiency, Hitachi's AMN family currently includes the AMN 6100 DWDM system and the AMN 5192 next-generation SONET transport system. Hitachi's AMN 6100 DWDM system offers transmission at 320 Gb/s using wavelengths in the C-band, with inservice upgrade to 640 Gb/s using L-band wavelengths. Future inservice upgrade to 1.28 Tb/s is planned.

Hitachi's next generation AMN 5192 transport system is designed to address a full range of applications from long haul transmission to metropolitan rings. The system supports growth from 10 Gb/s and beyond through Dense Wavelength Division Multiplexing. The four-fiber bi-directional line switched ring configuration provides protection against transport network outages due to a fiber cut or failure at one node. In the event of such a failure, traffic is automatically reversed in direction around the ring within milliseconds.
