Cable-Tec Expo 2003

STATE COLLEGE, Pa.--(BUSINESS WIRE)--May 9, 2003

C-COR.net Corp.(Nasdaq:CCBL) celebrates five decades in the cable industry at this year's SCTE (Society of Cable and Telecommunications Engineers) Cable-Tec Expo in Philadelphia, May 11-14. From cable pioneer to today's top-tier global company, C-COR remains 100 percent broadband-focused, drawing upon its historical experience in cable and in-depth knowledge of its global customer base to provide leading-edge, full network life cycle solutions for our dynamic industry. Recognizing that network integrity and superior value are key to success, CEO David Woodle sums up C-COR's mission as follows: "Our customers' customers buy a service; they don't buy a network. Our job is to help cable operators provide those services flawlessly."

Cable's multi-service networks necessitate superior products, a high-level of technical management, and pro-active maintenance. C-COR's three-prong offerings of products, software, and services, developed specifically to meet these advanced network demands, will be showcased in its SCTE Exhibitor Booth No. 1360.

Metro-Access and Metro-Core Products: Advanced Technology for Reliable Multi-Service Broadband Networks

At this year's Cable-Tec Expo, C-COR will introduce new product branding for its Metro-Access offerings to reflect its fully integrated product lines following major acquisitions from ADC and Philips. C-COR's Metro-Access products are deployed in the local hybrid fiber coax network to deliver two-way services from the operator's local headend to the subscriber's home or business. At SCTE, C-COR will feature the following Metro-Access products, offered by its Broadband Communications Products Division:

-- The CHP Max5000, the smallest and densest headend optics

platform in the industry. C-COR will demonstrate the CHP's new

dual input forward transmitter that provides over 60 dB of

isolation between services, making it ideal for applications

such as VoIP and high-speed data. Additionally, C-COR will

provide a demonstration of the CHP's Gigabit Transport Module.

This module offers Gigabit Ethernet grooming, making the 2.4

Gigabit WAN more bandwidth efficient and cost effective for

transport of MPEG-2 packets used in VOD applications.

-- C-COR's flexible line of nodes-- the Opti Max4000, Opti

Max3000, and Opti Max1000 address fully segmentable,

multi-functional, and fiber-deep node applications,

respectively. For European applications, C-COR will also have

the Opti Max2000 Cabinet Node available for demonstration in

the booth.

-- C-COR's highly regarded and flexible amplifier product line--

the Flex Max series.

C-COR will also demonstrate its system of modular, high-performance optical communications products in local headend-to-hub-to-home and business network architectures that include transmitters and passive optics components for return path DWDM (Dense Wavelength Division Multiplexing) applications.

On the Metro-Core side, C-COR will display its DV6000(TM) line of digital transport products that network local headends with other cable facilities or third-party operations to transport high-quality video, data, and voice for a variety of applications, such as broadcast, distance learning, video surveillance, and video-on-demand. C-COR will provide a demonstration of the recently released DV Ethernet Switch Modules, and advanced IMI-9000 monitoring system.

The Integrated Services Management (ISM(TM)) Solution: Using OSS to Increase ROI and Decrease Operational Costs

C-COR will provide live demonstrations of two of the modules under its flagship OSS market offering, the ISM, a comprehensive suite of software applications for proactively managing broadband service delivery and network integrity, developed by its Broadband Management Solutions division.

-- The ISM-NSM(TM) (Network Service Manager), currently deployed

by Bright House Networks in Tampa, Florida, and Time Warner

Cable in Hawaii, integrates best-in-class, standards-based

network management technology with customer care and billing

data sources to enable operators to proactively monitor and

manage the health of their network infrastructure.

-- The ISM-MWM(TM) (Mobile Workforce Manager), implemented by

a number of MSOs, including Time Warner Cable and Insight

Communications, provides cable operators with automated

routing, dispatch, and workflow management tools as well as

real-time monitoring and business intelligence reporting

capabilities that result in cost reductions and improved work

capacity for their field workforce activities.

Technical Services: Skilled Hands-On Field Service for Complex Broadband Networks

Representatives from C-COR's Broadband Network Services (BNS) division will be available in the C-COR booth to discuss their respected Worldbridge(TM) technical services for engineering, design, and deployment of advanced applications over broadband networks. With regional offices throughout the U.S., this group of professionals provides customers with outsourced operational services, network design and engineering, network integration services, outside plant and construction services, and consulting.

In line with the venue location for the 2003 Cable-Tec Expo in Philadelphia and SCTE's Expo Night Gala at The Franklin Institute, C-COR will be awarding a $100 bill (that features Benjamin Franklin's portrait) to the winner of each of five drawings held at the C-COR booth between May 12 and 14. Names of the winners will be posted on the C-COR Web site (www.c-cor.net).
