Business Editors & Technology Writers

MINNEAPOLIS--(BUSINESS WIRE)--May 3, 2000

Global Systems Integrator and Consulting Firm to Deploy and

Demonstrate Convergent Customer Care and Billing System

as Part of a Full OSS Suite in its Dallas Data Center

ADC (Nasdaq: ADCT; www.adc.com) today announced that professional services powerhouse Ernst & Young LLP, one of the world's leading system integrators, will use its Dallas Accelerated Billing and Operations Support Systems (B/OSS) Solution and Delivery Center to integrate Singl.eView(TM) into other market leading business and operations support systems. Ernst & Young and ADC will be able to provide fully integrated end-to-end solutions to their customers.

Relying on its broad understanding of the complete B/OSS application landscape, Ernst & Young will use a number of accelerated tools and techniques to perform customer-specific configurations and testing at the center to ensure customers get the most from their applications. This will significantly speed up the implementation process and provide critical time-to-market advantages. Ernst & Young and ADC will also be able to demonstrate to prospective clients how they can compete more effectively with Singl.eView as their comprehensive convergent customer care and billing solution.

Integrated communications providers (ICPs), Internet service providers (ISPs) and other telecommunications companies can now rely on the combination of ADC's expertise in convergent customer care and billing and Ernst & Young's extensive systems integration experience to gain a competitive market advantage. Rather than spending large amounts of time and money trying to deploy a convergent customer care and billing system themselves, service providers can rapidly deploy a system that will help them boost customer retention and expand their customer base.

"ADC has established a track record for delivering convergent customer care and billing solutions that help CLECs, ISPs, and other service providers easily add new services and boost customer satisfaction," said Cathy Culp, telecom billing service line leader at Ernst & Young. "Deploying such comprehensive systems can be a costly nightmare for service providers without the technical expertise to do so. Together, Ernst & Young and ADC can give emerging CLECs a time-to-market advantage with a solution that will enable them to compete more effectively."

Faster time to market through Accelerated B/OSS Solution/Delivery

Center

Ernst & Young's facility enables service providers to evaluate and determine the B/OSS architecture and application set that best suits their needs. At the B/OSS Delivery Center, Ernst & Young can configure the system the service provider wants and create the actual client interfaces to facilitate fast deployment. Integrating Singl.eView and other OSS applications means Ernst & Young can run tests there to ensure smooth operation before deploying the systems at the service provider's site. Ernst & Young can also train service providers on how to use Singl.eView at the Delivery Center prior to deployment.

The Singl.eView advantage

Singl.eView relies on an expression-driven architecture that eliminates expensive, time-consuming custom coding to meet changing market demands. For example, Singl.eView's flexible rating structure enables service providers to create special discount offers without the limitations imposed by fixed tables and custom coding.

Singl.eView grows with a service provider's customer base. It will also facilitate how service providers expand their product and service offerings to include future innovations by allowing them to simply add new pre-configurations to the system.

"Ernst & Young has built a solid reputation for successful systems integration in the telecommunications industry," said Larry Barker, president of ADC Software Systems Division. "Their integration expertise coupled with Singl.eView's open architecture gives service providers a way to rapidly deploy a key part of their OSS -- a convergent customer care and billing solution they need to grow and remain competitive."

Singl.eView is an integral part of Singularit.e, ADC's new suite of products and services that allows ICPs to build open operational support systems (OSSs) to compete more effectively in the broadband era. Singularit.e automates key OSS processes by combining real-time convergent billing, advanced customer management and service assurance technology with integration services from leading consulting companies.
