LAS VEGAS--(BUSINESS WIRE)--May 5, 1998--AT&T Solutions announced an important new managed network service at the Networld + InterOp '98 tradeshow here today for corporations that need flexible, dynamic bandwidth on demand for applications requiring multiple networks.

The new offering, AT&T Managed Bandwidth Service, integrates corporate voice, image, video and data network bandwidth requirements at a customer's premises with a common, managed end-to-end global platform of AT&T services.
