said it would use the companies' gear in building its new Internet protocol network.

San Jose, Calif.-based Redback said BellSouth would use Redback's SmartEdge Service Gateway platform. Paris-based Alcatel said BellSouth has identified the French company as its preferred supplier of digital subscriber line access multiplexers, the tool big telcos use to deliver high-speed Net access over existing copper phone lines.

The companies say BellSouth's new network will enable the delivery of so-called triple-play phone, cable and broadband Internet services. SmartEdge will also serve as the new architecture for subscriber management, Redback said, adding that deployment of the systems could begin as early as the second half of 2005.

"Today marks a critical milestone for Redback Networks, as BellSouth is one of the most highly regarded carriers in the world," said CEO Kevin DeNuccio. "We are thrilled to extend our relationship with BellSouth into this very important network transformation project," said Alcatel's Mike Quigley.

On Tuesday, Redback rose 26 cents to $7.54, and Alcatel added 24 cents to $12.84.
