STATE COLLEGE, Pa.--(BUSINESS WIRE)--May 27, 2004

C-COR.net Corp. (Nasdaq:CCBL), a global provider of broadband communications transport products, software systems, and technical services, today announced that it has completed the purchase of substantially all of the assets and certain liabilities of Alopa Networks, Inc., under the terms and conditions of the agreement previously announced on May 11, 2004. California-based Alopa Networks is a provider of subscriber-centric software solutions for end-to-end activation, management, and assurance of digital services over cable. With the completion of this purchase, Alopa becomes part of C-COR's Broadband Management Solutions (BMS) division, and the Alopa MetaServ(TM) platform will be added as a component of the BMS ISM(TM) (Integrated Services Management) suite of OSS (operations support systems) solutions for the broadband industry.

Alopa Networks is an industry driver in developing OSS solutions for broadband service providers that accelerate time-to-market for advanced network-based services and applications, including Internet telephone (VoIP), differentiated access, security, multimedia, and more. Alopa's combined family of products automates the complete life cycle of subscriber acquisition and service management by facilitating service creation, deployment, and assurance and security functions while, at the same time, accelerating revenue and lowering operating and capital expenses. Its flagship Alopa MetaServ platform is currently the only industry solution that automates the entire subscriber life cycle--from equipment qualification through service creation and activation to customer support--and integrates all layers of the IT infrastructure, including billing, order entry, customer care, and network management. It also provides secure provisioning for both PacketCable(TM) and CableHome(TM) networks, offering a framework for VoIP, multimedia services, and interactive gaming.

Alopa MetaServ is designed to support advanced data, voice, and video services with little or no development effort, minimizing or eliminating service support costs. Further, the platform's open architecture allows seamless integration with existing network infrastructures and IT architectures, thereby ensuring easy adaptability to emerging broadband standards. C-COR's OSS specialists will demonstrate the MetaServ platform as well as the Network Service Manager and Mobile Workforce Manager components of its comprehensive software solution in C-COR's booth #856 at the SCTE (Society of Cable and Telecommunications Engineers) Cable-Tec Expo, June 15-18, 2004, in Orlando, Florida.
