Robust Network Elements Combine to Offer Internet Access at Broadband

Speeds; Highly Scalable, Flexible DSL Networking Solution

Assured Access Technology (Milpitas, Calif.), a leading provider of multi-service access concentrators, and Diamond Lane(R) Communications, the industry's leading supplier of ATM-based, multi-service DSL (Digital Subscriber Line) access systems, today announced the successful completion of interoperability testing between Assured Access' new Broadband Remote Access Server platform and the Speedlink(TM) System from Diamond Lane.

Working together, the Speedlink System and Broadband RAS enable service providers to rapidly expand their installed base of customers, leverage their infrastructure investment and seamlessly integrate multiple incompatible DSL implementations into current operational systems.

Diamond Lane's multi-service Speedlink System allows service providers to simultaneously offer all popular DSL modulation technologies. ADSL-DMT, G.Lite, ADSL-CAP, SDSL and IDSL services can all be provisioned on the same shelf and system. The Speedlink System also offers both CLECs and ILECs the best operational efficiencies in the DSL industry, by scaling up to 2304 lines of DSL in one system. Its unique dual-stage star architecture gives service provides the flexibility to deploy the system within a central office or at remote locations.

Assured Access' Broadband RAS capabilities fill in the missing piece of the DSL network architecture by providing the internetworking glue between Digital Subscriber Line Access Multiplexers (DSLAMs) and Internet Backbone Routers. A single Broadband RAS shelf can terminate up to 48,000 permanent virtual circuits (PVCs) and up to 48,000 PPP sessions in a PPP over ATM service architecture. These capabilities are available on all of Assured Access' family of multi-service access concentrators. By using these products in their networks to provide flexible, high-speed access to the Internet, any service provider can support tens of thousands of DSL users and dozens of customer networks.

"Interoperability between the Assured Access and Diamond Lane products are part of our commitment to providing Service Providers with the products and services they need to deploy broadband networks for their customers," said Marilyn Suey, Assured Access Vice President of Marketing. "In the DSL services market, interoperability between network elements like ours is key for the rapid growth of high-speed Internet access."

"Service providers must be able to meet varying customer demands," said Ron Young, Vice President of Marketing at Diamond Lane. "By proving interoperability with Assured Access' products, we have created an end-to-end DSL infrastructure that helps accelerate the growth of the DSL market. The scalability of both the Speedlink System and Assured Access Broadband RAS offers an ideal solution for the mass-market deployment of DSL services."
