BigBand Networks Unveils BEQ(TM)6000; First Universal Edge QAM Deployed for Both Switched Digital Video and Modular CMTS.

BigBand's Third-Generation Edge QAM Platform Deployed on Three Continents; Delivers Industry's Lowest Total Cost of Ownership Through Superior RF Performance

REDWOOD CITY, Calif. -- BigBand Networks, Inc. (NASDAQ:BBND), today unveiled its "universal" edge quadrature amplitude modulation (QAM) platform -- the Broadband Edge QAM (BEQ[TM]) 6000 -- designed to deliver a wide range of services, including video-on-demand (VOD), switched digital video, network PVR, video-over-DOCSIS([R]), high-speed data and voice-over-IP. BigBand believes it is the first company to deploy universal edge QAMs to provide switched digital video (SDV) and modular cable modem termination system (M-CMTS). Cox Communications is deploying the BigBand BEQ6000 to power its SDV deployment in Northern Virginia. Dutch operator Multikabel has deployed the BEQ6000 platform for M-CMTS to provide high-speed data and voice-over-IP services, and Japanese operators Cable Networks Akita, Hino Cable Television and Bay Communications are using the BEQ6000 to deliver high-speed data services as well. BigBand believes it has deployed more edge QAMs for SDV and M-CMTS than all of its competitors combined.

"BigBand's universal edge QAM deployments for SDV and M-CMTS are breakthroughs," said Gerry Kaufhold, principal analyst for In-Stat. "Versatile QAM platforms, with the ability to support video, data or voice services, are key to keeping costs down and efficiency up as operators ramp up to deliver more bandwidth and new services."

While the pricing of today's platforms is roughly equivalent, price-per-QAM has incorrectly been a focal point in the analysis of edge QAM economics. The ongoing cost to maintain and operate each QAM platform can vary widely, and thus total cost of ownership is the more accurate measure of an edge QAM platform's true cost to operators. The BEQ6000 establishes a number of industry benchmarks designed to enable it to achieve what BigBand estimates to be the lowest total cost of ownership of any available edge QAM platform. BEQ6000 benchmarks include:

* Lower operational cost. BigBand estimates that the BEQ6000 achieves a forty percent improvement in operational cost over other leading edge QAM platforms. The BEQ6000's protocol support, power efficiency, RF performance and reliability are designed to lower the operational costs associated with delivering video, data and voice services.

* Superior RF performance. The BEQ6000 achieves QAM modulation with more than twice the signal quality and up to twice the signal level compared to other leading QAM devices on the market today. This enables operators to achieve a high quality-of-service for a broad range of applications, even as they migrate to new, advanced technologies such as M-CMTS and SDV.

* Superior reliability. The BEQ6000 has been designed with a balance of density, functional design, component durability, signal quality and modularity designed to make it the industry's most reliable edge QAM platform. BigBand has customized high-quality components -- such as power supply and fans -- to improve product uptime and enable longer product life. BigBand believes the BEQ6000 also features the industry's only service-level fault detection and protection switching to maximize the benefit of redundant transport and minimize the impact of routine network maintenance.

BigBand's SDV and M-CMTS are two of the most economically beneficial technology solutions in the cable industry. SDV is designed to allow cable operators to expand to virtually infinite programming and increasingly personalize content by delivering programs only where they are requested. BigBand's M-CMTS can substantially lower the cost of increasing broadband speeds by leveraging the BEQ6000 to perform some of the capabilities traditionally performed by the CMTS core.

"The universal edge QAM is a significant breakthrough for the cable industry; it can simultaneously enable new video and data services and lower the cost of providing them," said John Holobinko, BigBand's vice president and general manager of cable IP. "The BEQ6000's superior RF performance and reliability are designed to allow operators to ensure quality across services, and significantly reduce operational costs."
