C-COR and ARRIS Drive Cable's Competitive Opportunities with On Demand Dynamic Bandwidth Management.

STATE COLLEGE, Pa. & SUWANEE, Ga. -- Companies Interface C-COR PSM(TM) and ARRIS Cadant(R) C3(TM) CMTS Products for ANGA 2006 Demonstration of Consumer-Driven, On Demand, On-the-Fly Service Selection and Bandwidth Allocation

C-COR Incorporated (NASDAQ:CCBL) and ARRIS (NASDAQ:ARRS), leading technology providers to the global communications marketplace, are showcasing at the ANGA Cable Trade Fair 2006 in Cologne, Germany (May 30-June 1, 2006) a joint demonstration of on demand bandwidth allocation for VOD and other triple play services that creates value to the consumer and potential revenue streams to the cable operator. Two joint demonstrations, one each in C-COR's Booth D-14 and in ARRIS' Booth H-20, combine C-COR's Policy Service Manager (PSM(TM)) and the ARRIS Cadant(R) C3(TM) CMTS (Cable Modem Termination System) to support a TurboButton application that allows the cable subscriber to dynamically and on-the-fly request a selected service and a specific allocation of bandwidth for a high quality viewing experience.

"Cable operators are approaching a major crossroad," said Rod Peery, C-COR's Director of Sales, EMEA. "They have a choice of becoming a seller of commodity bandwidth or leveraging the intelligent-based technology demonstrated by C-COR and ARRIS to deliver the quality of service that retains and gains customers while opening up advanced billing methods, such as usage-based, prepaid, pay-per-use, and on demand, for additional revenues."

"This PacketCable Multimedia-based technology enables many new, dynamic services for cable operators," said Charles Cheevers, ARRIS CTO, Europe. "With this technology, cable operators can enhance their present network capabilities to further differentiate their offerings from competitors' services and lead the broadband industry. We are excited about demonstrating this unique PCMM-based feature on the C3 ahead of its general availability, which is anticipated to be in the second half of this year."

C-COR's Policy Service Manager provides dynamic, on demand bandwidth management to enable many of today's popular multimedia applications such as video-on-demand, gaming, and Internet telephony. PSM ensures standards-based quality of service (QoS) based on CableLabs(R) PacketCable(TM) Multimedia (PCMM) specifications. It provides cable operators with a powerful set of capabilities, including:

--Dynamic adjustments to bandwidth to ensure QoS for real-time and multimedia applications, eliminate capital costs of over-provisioning, and enable potential revenue from bandwidth-on-demand;

--Standards-based to interface with industry-leading CMTS vendors and back office recordkeeping servers for event-based billing;

--Application Management and Service Level control for subscribers to enable advanced billing options;

--Distributed architecture to scale to any scope or capacity;

--Proactive congestion management to allow bandwidth management based on projected network congestion conditions; and

--Security to proactively prevent network abuse and bandwidth consumption beyond Service Level Agreements (SLAs).

The ARRIS Cadant C3 CMTS is DOCSIS(R) 2.0 qualified / Euro-DOCSIS 2.0 based and has the versatility to provide a wide array of residential and commercial services (high speed data, VoIP, Layer 2 VPN, DS1, Wireless DOCSIS). A digital receiver, ingress noise cancellation and advanced error correction capability provide superior RF performance for challenging HFC plant conditions. The high density design (3,000 registered cable modems in 1RU) has the configuration flexibility (2, 4 or 6 upstream channels) to match anticipated traffic patterns. Traffic load balancing between upstream channels is done periodically based on bandwidth utilization. Layer 3 routing (OSPF, RIP, static) and Layer 2 bridging are provisionable on a per sub-interface basis. A dual processor architecture with Fast/Gigabit Ethernet interfaces facilitates high packet throughput.
