CableMatrix and BigBand Networks Demonstrate Advanced Multimedia Applications at 2005 ANGA Cable Trade Fair.

COLOGNE, Germany -- Combination of Broadband Access, Policy Management, and Application Platforms Enables Broad Range of Services Spanning Telephony, Multimedia Services and Accelerated File Backup

CableMatrix Technologies, Inc., a primary vendor of PacketCable(TM) Multimedia (PCMM)-based solutions, and BigBand Networks, Inc., a leading provider of network platforms for video, voice and data services, are showing a broad array of advanced services at the 2005 ANGA Cable Trade Fair, held here through June 2. Live applications of CableMatrix solutions on display at the BigBand Networks booth (# B24) include:

--A deployable low-cost, high-quality SIP telephony solution;

--A high-resolution, full-screen video streaming application, along with an enhanced video telephony system, that can differentiates cable network capabilities; and

--A file backup application that can utilize off-peak network capacity to generate additional revenue.

"BigBand Networks emphasizes solutions-enabling platforms, and we believe our work with CableMatrix can bring about new service possibilities for our broadband network operator customers," said BigBand Networks Chief Technical Officer Ran Oz. "Operators are expanding service offerings across business and consumer applications, as well as video, voice and data media, and BigBand Networks and CableMatrix are teaming up to deliver key capabilities to the European market and worldwide."

The ANGA demonstration consists of the BigBand Cuda(R) CMTS (cable modem termination system) integrated with CableMatrix's ODSP(TM)(On Demand Service Platform) PCMM solutions suite. The BigBand Cuda enables a range of IP capabilities within a networked, multi-service environment. The platform's redundancy design and RF modulation technology are designed to maximize service availability for subscriber satisfaction. The scalable architecture allows for capacity increases and feature additions over time.

The DOCSIS 2.0-qualified Cuda CMTS is deployed for advanced, multimedia services such as VoIP and multi-megabit access, including several prominent European successes. BigBand Networks is engaging in modular CMTS and DOCSIS channel bonding development to advance Cuda's capabilities in deployment scalability, operating efficiency, and support for rich media services such as those managed by PCMM.

Viewed as the core technology for QoS (Quality of Service)-enabled services, the CableMatrix Policy Server is designed to concurrently manage thousands of diverse high-speed data sessions. To complement its Policy Server, CableMatrix recently announced the acquisition of Xinnia Technology and its unique "smart agent" platform, which accelerates the integration of PCMM-compliant applications.

"BigBand Networks has a proven track record of bringing innovative solutions to the market, and broadband service providers look to the company for leadership," said Avishai Keren, CableMatrix's VP of Engineering. "With that in mind, we are pleased to collaborate with BigBand Networks to advance the deployment of PCMM services."
