Business Editors & High-Tech Writers

SUNNYVALE, Calif.--(BUSINESS WIRE)--Jan. 5, 2000

Redback Networks (Nasdaq:RBAK) announced today that it has entered into a multi-year, multi-million dollar agreement in which Bell Atlantic has deployed the Redback Subscriber Management System(TM) (SMS) 1000.

This deployment will strengthen Bell Atlantic's consumer Asymmetric Digital Subscriber Line (ADSL) service offering, Infospeed(SM) DSL, providing broadband data access to its customers using Redback technology. Bell Atlantic is using Redback's subscriber management system to ensure that it will meet the high projected demand for its Infospeed high-speed ADSL service.

As one of the nation's leading providers of consumer and business broadband services, Bell Atlantic is building Redback's SMS into more than 80 points of presence (POPs). Bell Atlantic will also use the Redback SMS 1000 to provide DSL access to regional and national ISPs.

"The SMS 1000 was an integral part of Bell Atlantic's aggressive deployment of Infospeed DSL services in hundreds of central offices in 1999. It supports multiple service interfaces, and provides the scalability required to support a large customer base -- both of which are key requirements for Bell Atlantic," said Greg Evans, executive director, Technology for Bell Atlantic.

"Bell Atlantic's aggressive DSL roll-out program depends upon fast provisioning of new subscribers and seamless deployment of services to ISPs," said John DuBois, Eastern area vice president of sales at Redback. "Integrating Redback's SMS technology into its core infrastructure enables Bell Atlantic to provide subscribers with a faster installation experience and a future that is rich with new value-added services."
