Amber Networks Wins Product of the Month for World's First Aggregation Service Router Telecommunications Magazine Picks the ASR2000 for its 'Rock-Solid' Reliability.

Business Editors/High-Tech Writers

SANTA CLARA, Calif.--(BUSINESS WIRE)--August 1, 2000

Optical Internet start-up Amber Networks, the developer of a new class of carrier-grade service edge products known as Aggregation Service Routers, today announced that its ASR2000(TM) was selected as the product of the month by Telecommunications(R) Magazine, a leading industry publication. Calling the ASR2000 "rock-solid," the magazine based its selection on the product's reliability and fault tolerance, as well as port and logical subscriber densities that are as much as an order of magnitude better than any other edge device currently on the market.

Telecommunications editor in chief Sue O'Keefe explained that many parameters are used to select the magazine's featured products, including price/performance, functionality, ease of use, interoperability and the specific value proposition the product brings to the marketplace. "Telecommunications editors chose Amber Networks' ASR2000 for our August product of the month because the start-up has raised the bar in the aggregation router space, stealing the limelight from the incumbent, Cisco," O'Keefe said. "We were especially impressed with Amber's fault-tolerant OS -- the AmbOS(TM)."

Amber Networks' AmbOS represents a breakthrough in routing OS. It is the industry's first fault-tolerant router operating system that delivers stateful redundancy capable of restoring Layer 3 services with SONET-like speed -- at less than 50 milliseconds. Traditional router operating systems and router architectures are unable to maintain dynamically mirrored routing states and packet forwarding tables; therefore, when a router loses its primary control circuitry and falls back to the redundant controller, it causes a 5-15 minute outage.

Amber's ASR2000, which recently won the coveted SUPERQuest award at the SUPERCOMM 2000 trade show, is the first edge router to converge all services (TDM private line, Frame Relay, ATM and IP) to IP/Optical networks. The ASR2000 establishes a new product category which enables service providers to create the Optical Internet, a unified IP/Optical network that addresses the entire $75 billion services market.

Amber Networks joins a stellar roster of companies whose products have been featured in Telecommunications this year, including Alcatel and Sirocco Systems, Inc. (recently acquired by Sycamore Networks.)

Published by Horizon House(R), Telecommunications is a monthly magazine written for service provider executives. It covers a broad spectrum of telecommunications issues including next-generation networks, broadband access, wireless communications and optical networking. According to The Wall Street Journal, it is the second most widely-read monthly magazine among high-level telecommunications managers.
