MCI Introduces Trio of New Internet DSL Services Nationwide

Businesses Can Utilize One Product, One Provider Solution Across 300 Metro Areas in U.S.

ASHBURN, Va, NOVEMBER 9, 2004 - MCI, Inc. (MCIP) today announced it is rolling out a trio of new Internet Digital Subscriber Line (DSL) services to reach businesses in more than 300 metropolitan areas nationwide. The offerings comprise a single-provider solution to deploy cost-effective broadband Internet connections and extend MCI Internet Protocol Virtual Private Network (IP VPN) Service to geographically dispersed businesses more simply and affordably.

"With MCI's expanded DSL product portfolio, businesses can turn to MCI for uniform service nationwide, without the difficulty and complexity
of working with multiple solutions from multiple providers around the country," said Nancy Gofus, MCI senior vice president of Product Management. "MCI's new DSL suite underscores our continued focus on delivering IP products and services that offer businesses greater value and simplicity."

MCI's new trio of services - Internet DSL Solo 768 Kbps, Internet DSL Solo 1.5 M and Internet DSL Solo Resale-is ideal for businesses like retailers, service companies and other organizations with multiple
locations, requiring cost effective, "always on" connectivity to the Internet. MCI DSL Services are also well-suited for teleworkers needing the same high-speed, high-performance connectivity as their office counterparts to corporate resources and the Internet.

With MCI's new offerings, companies can implement standardized DSL Internet access from more than 8,800 switching centers, representing more than 85 percent of all U.S. locations where business DSL is
available today. Offering consistent access speeds and customer premise equipment (CPE), MCI provides a comprehensive package of asymmetric
business-grade DSL Internet access solutions including 24 x 7 technical service and support and consolidated billing.

For customers wanting to enhance their DSL security, MCI offers IP VPN Broadband, a managed solution that encrypts the traffic between remote
locations and corporate headquarters over MCI's DSL offerings. This solution is targeted to medium and large customers with retail store and
small office applications. Ideal for large scale deployments, MCI's IP VPN Broadband Service is delivered to customer sites pre-configured and
ready for immediate installation, allowing remote company locations to get online quickly and easily.

In June 2004, MCI and New Edge Networks, a national provider of multi-site broadband networks for business and carrier customers, announced the companies had extended their strategic relationship to deliver additional DSL services to more MCI business customers nationwide. Through New Edge's expanded broadband reach called 'Bigfoot,' MCI now offers and supports DSL services in 300 metro areas in the U.S.
