Telecommunications Magazine Names Seranoa Networks ``Hot Start-Up'' for 2004.

CHICAGO -- Seranoa Networks (www.seranoa.com), the leading provider of service edge solutions, was named Hot Start-Up for 2004 today by Telecommunications Magazine. Seranoa Networks was one of only ten start-ups in the telecommunications industry to be selected for this internationally recognized award. Editors at the publication chose this year's hot companies to watch based on their ability to succeed, despite the challenging market climate. The award ceremony will take place on June 22 at the SuperComm 2004 show.

"Seranoa's service edge concentrators are designed to help service providers easily transition from TDM-based services to IP-based voice and data services. The difference between this start-up and the incumbent edge router vendors is that Seranoa's products cost-effectively address the aggregation of IP business subscribers while also significantly optimizing the value of traditional TDM business services. It's a tough market, but among the competition we've seen, Seranoa has one of the best opportunities to gain traction," said Sue O'Keefe, Editor in Chief, Telecommunications Magazine.

"To be recognized by Telecommunications Magazine with the distinction of Hot Start-Up Company this year, is an honor and a thrill for the whole Seranoa team that has worked so hard over a long period to get to this point," said Graham Pattison, President and CEO of Seranoa Networks. "This award, along with our customer's deployments, reaffirms the industry acceptance of our approach to solving today's Service Provider critical issues while embedding technology for their future needs."

The IPeX family of carrier-class Service Edge Concentrators from Seranoa Networks allows service providers to more efficiently and cost-effectively deliver popular IP services with traditional TDM-based services to business customers, while leveraging their embedded access infrastructure. With its unique IP-aware switching technology, Seranoa is changing the economics of network access and edge aggregation so providers can immediately improve the profitability of existing business services while facilitating a convergence to a core IP/MPLS data network.

"Service providers are at the inflection point where they must offer popular IP-based services to customers - but also continue to deliver their legacy PSTN services. Delivering traditional TDM services with packet services over an existing SONET metro/access infrastructure - reliably and profitably - becomes the challenge," said Deb Mielke, President of Treillage Network Strategies Inc. "Seranoa offers service providers the ability to manage this transition cost effectively. By pushing IP intelligence to the edge of the network, and maintaining TDM services as TDM, service providers can cost-efficiently utilize transport bandwidth while preserving traditional services and enabling new service revenues. And they have a way to do it without making big changes to the portions of the network (access) where change can be 'pricey' and time consuming (operations, management, process, etc.)."
