New Dedicated Analysis Tool Enables Any Size Company
to Better Monitor Network Performance

Standards-Based NxT1 Solution Boosts Dedicated Bandwidth,
Cuts Internet Access Costs for Small/Mid-Size Businesses

CLINTON, Miss., October 23, 2002 - WorldCom (WCOEQ), the leading global business data and Internet communications provider, today unveiled WorldCom Dedicated Analysis^SM one of the first commercially available end-to-end dedicated Internet access-monitoring tool for companies of all sizes. The company also introduced a new standards-based NxT1 access solution to fill the gap between popular T1 (1.5 Mbps) and T3 (45 Mbps) dedicated Internet connections to WorldCom's UUNET® backbone for small- to medium-size businesses.

"The launch of WorldCom Dedicated Analysis and our new NxT1 dedicated access solution epitomize WorldCom's unwavering commitment to develop and deliver the kind of innovative services business customers are asking for," said Frank Grillo, WorldCom senior vice president of marketing. "Coming on the heels of the introduction of The WorldCom Connection - our new IP-based converged voice and data network service - these new offerings further solidify WorldCom's position as the source for business communications solutions for companies of every size and shape."

WorldCom Dedicated Analysis
For the first time, through Dedicated Analysis, customers have a tool to monitor their end-to-end Internet network performance at the access level. In fourth quarter of 2002, all WorldCom Dedicated Internet Access customers - including T1, OCn, Ethernet and NxT1 connections to the UUNET backbone - can take advantage of WorldCom's unique new Dedicated Analysis monitoring tool.

"By incorporating Dedicated Analysis into their WorldCom-provided dedicated access solutions, IT managers have the power to easily analyze the efficiency of their network services and view customer-specific dedicated traffic statistics with just a few mouse clicks," said Grillo. "Similar to our groundbreaking WorldCom Dial Analysis^SM solution for Internet dial customers, Dedicated Analysis uniquely provides the kind of detailed network performance visibility that is essential in today's information-driven business environment."

Supported by Visual Networks IP performance management technology, WorldCom Dedicated Analysis allows network administrators to monitor the quality and performance of their circuits as needed, on-demand. Network statistics, including latency and packet loss, are updated daily and can be accessed anywhere, any time, via the secure WorldCom Customer Center (WCC) Web portal (http://customercenter.worldcom.com).

"Despite its Chapter 11 status, WorldCom continues to demonstrate its ability to provide innovative and flexible solutions," said Steve Harris, research manager at IDC. "WorldCom's Dedicated Analysis and NxT1 are examples of forward thinking services that will be valuable additions to WorldCom's portfolio."

WorldCom NxT1 Solution
WorldCom's newest Dedicated Internet Access service, NxT1, is a breakthrough bandwidth solution for small- to medium-sized businesses. NxT1 is designed for SMBs whose Internet needs exceed the capacity of a T1, but cannot justify the expense of a T3. Unlike a T3 line with a set bandwidth of 45 Mbps, WorldCom's NxT1 solution brings together multiple T1 connections to WorldCom's UUNET backbone, creating the appearance and performance of a single high-bandwidth data pipe and the flexibility for customers to individually customize their bandwidth solution to their individual business requirements.

"When a T1 is no longer enough, but a T3 is too much, the answer is WorldCom NxT1," said Grillo. "NxT1 enables small and mid-size businesses to maximize their IT spending by purchasing bandwidth in digestible amounts that fit their needs now with the ability to easily add data capacity as their business grows. It is the solution for bandwidth management in a disciplined budget atmosphere."

Capitalizing on new standards-based Multi Link Frame Relay (MLFR) technology, WorldCom's NxT1 solution enables customers to utilize from two to eight T1 lines at a single location. By aggregating T1 circuits together, customers save on local loop costs while gaining greater bandwidth flexibility and increased reliability through circuit redundancy. Using Tasman customer premise equipment, WorldCom is leading the industry by offering an NxT1 solution utilizing MFLR technology and connections up to 12 Mbps, the equivalent of eight T1 lines.

Currently available in more than 2,000 U.S. municipalities, WorldCom's NxT1 solution is backed by some of the most precise and comprehensive Service Level Agreements (SLAs) available in the industry today. The SLAs for NxT1 and all of WorldCom's Internet Dedicated Access services include guarantees for Latency, Packet Delivery, Availability, Installation and Proactive Notification.
