Harmonic Lightwaves Announces New, Compact Return Path Receiver; Custom Designed For Implementation of Interactive Services, Such as Internet, Video-On-Demand, Pay-Per-View and Telephony; Users Can Replace Receivers Without Interruption of Service.

SUNNYVALE, Calif.--(BUSINESS WIRE)--Nov. 25, 1996--Harmonic Lightwaves, Inc. (NASDAQ: HLIT), a leading developer of fiber optic transmission and element management systems for broadband communications, today announced a new high-output return path receiver (RPR) module that is optimized for the performance and reliability requirements of tomorrow's fully interactive broadband communication systems.

Additionally, the RPR 2210 is designed to offer the industry's highest packaging density, containing 20 receivers in only three rack units of space.

"With the delivery of expanded services, such as the Internet, telephony, video-on-demand and pay-per-view, major service operators can not afford interruption of service for even a few minutes," said John Dahlquist, vice president of marketing for Harmonic Lightwaves.

"Harmonic's new RPR 2210 when deployed in redundant network applications, enables the replacement of cards without downtime -- offering a significant increase in system reliability for service providers and customer satisfaction for subscribers."

The RPR 2210, built for the headends and hubs of cable networks, mounts in Harmonic's HTR 2000D chassis and offers the ultimate in packaging density -- two complete, independent RPRs on one board. Operators can effectively install up to 20 RPRs in three rack units.

The RPR 2210 also offers built-in flexibility, enabling users to switch the RPR to serve as a either a primary or backup unit -- even when located in different chassis. Users can also set the unit to the specific optical level at which they want it to switch from primary to backup; redundant switching is automatic and instantaneous.

The receivers are part of a complete series of headend return path equipment offered by Harmonic. The RPR 2210 and HTR 2000D offer several different monitoring and control configurations depending on the customers' needs. All Harmonic equipment allows for the implementation of the company's NETWatch element management and control system.

The return path receiver is used in broadband networks to receive return system data and return network management information from remote system components by converting optical signals to RF signals. The modular design of the modules allows for high-density packaging, reducing headend space requirements; system interoperability; and ease of use.

Harmonic Lightwaves is now shipping the RPR 2210 and has received volume orders from major service providers such as Tele-Communications, Inc.; Cox Communications, Inc.; and Continental Cablevision.
