Allied Telesyn Broadens Interoperability with Nortel DMS10 Call Server Certification.

SAN JOSE, Calif. -- Allied Telesyn, a global provider of secure Ethernet/IP access solutions and an industry leader in the deployment of IP Triple Play networks over copper and fiber access infrastructures, today announced that it has successfully completed interoperability testing between its iMG600 family of intelligent Multiservice Gateways and the Nortel DMS-10 release 601 Call Server SIP interface. Rural carriers and independent operating companies now have additional capability with which to drive revenue-generating IP voice, video and data services.

Nortel has issued a certificate of compatibility for Allied Telesyn's iMG600 family of intelligent Multiservice Gateways after successful completion of interoperability testing with Nortel's SIP-enabled DMS-10, the industry's most widely deployed voice switch.

"Allied Telesyn continues to add capability to its IP/Ethernet networking solutions and our partnership with Nortel reinforces that," says Allied Telesyn's Executive Vice President of Marketing and Product Development Philip Yim. "Our certified interoperability with Nortel will enable forward-thinking carriers and rural telephone companies to introduce exciting new IP voice video and data services with confidence."

Allied Telesyn offers a wide array of iMG intelligent Multiservice Gateways for ADSL and Fiber-To-The-Home (FTTH) networks, available in a variety of configurations and speeds. The iMG600 family combines support of IP Multicasting, QoS capabilities and the bandwidth capacity of fiber to deliver multiple video streams, IP Telephony and high-speed Internet access to subscribers. Using iMGs and next-generation FTTH or xDSL access infrastructure such as Allied Telesyn's iMAP integrated Multiservice Access Platform, service providers are able to provide their end-user customers with a wide spectrum of converged services from a single end-to-end system.

The Allied Telesyn and Nortel solution is deployed at Skyline Telephone Membership Corporation, which serves northwestern North Carolina and eastern Tennessee. Skyline chose Allied Telesyn's iMAP integrated Multiservice Access Platform to upgrade its copper plant to a hybrid fiber infrastructure. The new 100Mb FTTH delivery network will support both active Ethernet and passive GEPON protocols over Allied Telesyn's 10 Gigabit transport to bring high-quality voice, video and data to more than 37,000 subscribers in the Blue Ridge Mountains. As well as deploying the iMAP integrated Multiservice Access Platform, Skyline is using two hardened iMGs -- the active Ethernet iMG646BD-ON, and the passive GEPON iMG646PX-ON.

"SkyLine has evolved with the communities we serve, taking the lead in identifying customer needs and offering innovative solutions -- our fiber to the home initiative is a perfect example of this evolution," said Jimmy Blevins, CTO, SkyLine Telephone. "Interoperability between Nortel and Allied Telesyn allows us to offer our customers new bundles of digital entertainment, voice, communication and information services with confidence, knowing that we can reliably provide our customers with the communications choices they need."
