Denver, October 11, 2001 ? Qwest Communications International Inc. (NYSE: Q), the broadband communications company, today announced it has successfully expanded its use of digital technology allowing Qwest to move voice telephone calls over its data networks. This next-generation, packet-switched network, trialed in Boise, Idaho, represents the first large-scale use by an incumbent local exchange carrier (ILEC) and is a critical milestone in Qwest?s strategy to carry voice over Internet protocol (IP) to customers everywhere.

?Qwest is continuously delivering revolutionary and robust networks to meet customers? broadband needs,? said Augie Cruciotti, Qwest executive vice president of local networks. ?With this trial, Qwest is once again at the forefront of the industry because of its innovative, first-to-market initiatives.?

Qwest plans aggressive packet-switched network deployments in Albuquerque, Denver, Minneapolis, Phoenix, Salt Lake City and Seattle. By using packet-switched networks, Qwest will be able to move voice calls across its network more efficiently because the number of circuits required to facilitate the millions of calls made each day is greatly reduced. The new network also will enable Qwest to deliver new consumer and business services, while increasing revenue and profitability.

Qwest leveraged Nortel Networks packet-based network including a carrier class softswitch. For more information about the Nortel Networks technology used in this deployment, see:
