EXTREME NETWORKS WIRELESS LAN MEETS AVAYA REQUIREMENTS.

Extreme Networks Inc. (NASDAQ:EXTR and Avaya Inc. (NYSE:AV , a leading global provider of business communications applications, systems and services, have successfully compliance tested Extreme Networks(R) Summit WM 200 and Summit WM 2000 wireless local area network (LAN) solutions with Avaya's market-leading Internet protocol (IP) telephony solutions.

Through Avaya's compliance process, Extreme Networks Summit WM 200, Summit WM 2000 controllers and Altitude Access Points (APs) were successfully tested for interoperability with Avaya Communication Manager 4.0 IP telephony software and with Avaya 3600 series wireless IP phones, featuring standards- based 802.11a/b/g technology for mobile communications.

Tests demonstrated that the Extreme Networks Summit WM wireless LAN controllers authenticated phones as they entered the wireless network and supported consistent calls with both Avaya wireless IP phones and Avaya IP softphones. Call sessions were also maintained without call shuffles or drops while devices roamed between separately located access points.

"Enterprises are seeking a seamless transition between their wired and wireless networks to support voice calls reliably and securely," said Suresh Gopalakrishnan, vice president and general manager for the Emerging Products Group for Extreme Networks. "Our Summit WM wireless LAN system provides the intelligence, security and roaming capabilities that are now tested with Avaya's world-class IP telephony solutions, giving customers the confidence they need to deploy a complete mobility solution."

Extreme Networks Summit WM wireless LAN controllers and Altitude APs were validated for interoperability through the Avaya DeveloperConnection program - an initiative to promote the development, compliance-testing and co-marketing of innovative third-party products that are compatible with standards-based Avaya solutions.

"With the compliance testing of wireless LAN solutions from Extreme Networks, Avaya customers have the opportunity to implement a fully interoperable mobility solution that can help them unleash powerful new possibilities for their business," adds Eric Rossman, vice president, developer relations and technical alliances, Avaya.
