SAN JOSE, Calif.--(BUSINESS WIRE)--Sept. 26, 2000

TeraBridge Technologies, developer of the PathMinder(TM) softswitch for call and connection control over IP and ATM next-generation broadband networks, and Talarian(TM) (Nasdaq: TALR), a leading provider of real-time infrastructure software, announced here today that TeraBridge has embedded Talarian's SmartSockets(R) into their PathMinder softswitch solution.

The TeraBridge PathMinder softswitch solution is a next-generation software-based switching technology that enables the delivery of voice, data and video services over a single packet-switched network. This advanced telecom solution enables service providers to deploy next-generation networks that are seen as the future of the Public Network. Such networks allow service providers to offer integrated multimedia services over a single network infrastructure while achieving significant cost savings over today's communications networks. By placing the SmartSockets real-time infrastructure at the core of their PathMinder product, TeraBridge equips service providers with a high-availability, fault-tolerant product, designed to reliably and securely scale across the Internet and other next-generation networks.

"Talarian met our corporate objectives of simplicity, flexibility and speed-to-market," said Don Swartz, Senior Vice President of Development and Production at TeraBridge. "These objectives have allowed TeraBridge to be the first commercially deployed softswitch in the nation."

Talarian's SmartSockets infrastructure software offers real-time, Guaranteed Message Delivery (GMD), fault tolerance, and easy-to-deploy architecture TeraBridge needed for their softswitch product. "SmartSockets simply fit our design requirements, which is why we saw it as the ideal infrastructure for our PathMinder solution," said Gary Yi, Director of Application Development at TeraBridge Technologies. "We found that other options, such as CORBA, were simply too complex and demanded too much time and effort to build and maintain. We have a very advanced, complex system; we didn't need our middleware making it more complex."

"The TeraBridge softswitch is one of the most scalable and robust in the telco arena, and we are pleased they chose to embed SmartSockets as their core infrastructure," said Tom Laffey, Chief Technology Officer of Talarian. "We are finding an increasing number of hardware and software companies - like TeraBridge -- embedding our software to get to market faster and provide them the robust environment they need for their real-time solutions."

The Embedded Systems Conference, taking place Sept. 24-28 in San Jose, Calif., is recognized as the largest and most prestigious event in the embedded systems industry. Talarian infrastructure software delivers this industry reliable IPC for HA systems with guaranteed message delivery, hot failover, and dynamic message routing. Conference attendees will find Talarian at booth No. 8051 and at the WindRiver (Nasdaq: WIND) Partner Pavillion, booth No. 830.
