NEW HAVEN, Conn. -- DSL.net, Inc. (NASDAQ: DSLN), a leading nationwide provider of broadband communications services to businesses, today announced that it would use Cisco Systems infrastructure equipment, including routers and gateways, as part of its integrated voice and data T-1 service offering.

"By combining the quality and reliability of the DSL.net broadband network with an all-IP Cisco solution, DSL.net is able to offer a high-quality T-1 bundled voice and data service to its business customers while realizing significantly reduced operating costs through an integrated platform," said Keith Markley, president and chief operating officer of DSL.net. "Traditional circuit-switched network architectures cannot match the functionality and flexibility that is offered by the combination of DSL.net's broadband network and the Cisco Systems equipment. The end result is a product that can give business customers substantial savings on their long-distance calls and unlimited local calling."

The Cisco Systems equipment being used in the DSL.net broadband network supports the Session Initiation Protocol (SIP) and includes the Cisco IAD2400 Series and the Cisco BTS 10200 Softswitch.

DSL.net has conducted interoperability testing in its lab of Cisco's softswitch-based networking equipment, which DSL.net plans to utilize in its expanded roll out of integrated voice and data services into Metro New York City, including Northern New Jersey, as well as Greater Boston and parts of Connecticut. DSL.net's NETgain One T-1 integrated voice and data offering is currently available in Washington, DC, and parts of Virginia and Maryland. DSL.net expects to continue interoperability testing over its network of next-generation Cisco equipment as it becomes available.
