PLANO, Texas -- Interphase Corporation (Nasdaq:INPH - News), an International supplier of next-generation networking technologies, today announced a live demonstration of a broadband-switched digital video network in the Interphase booth #611 at the NTCA Expo '05 in San Antonio. Interphase and its partners, Calix and Minerva, are demonstrating a cost-effective way for carriers to deploy new broadband services, in particular broadcast video, video-on-demand and IPTV. These interactive entertainment services are becoming increasingly popular with consumers and fueling growth for carrier broadband infrastructure spending.

This solution set delivers advanced IP-based voice, video, and data to the end-user, the highly sought after "triple play" services, and it enables services providers to offer these services in a variety of broadband access and broadcast applications. The demonstration shows the transport of 132 simultaneous video channels over DSL, with the Calix C7 serving as the DSL access multiplexer, the Interphase iNAV® 9200 as an Ethernet to ATM bridge, and the Minerva VC8000 performing video encoding to convert video to multicast IP video streams.

"This combined solution enables service providers to quickly capitalize on the emerging 'triple-play' market by offering ease of integration into existing DSL networks," said Randall McComas, Vice President of Global Sales and Marketing for Interphase Corporation. "We are pleased to work with our partners who are experts at deploying these services, to further expand the reach of our iNAV 9200 in the most high-growth segments of the market."

The Interphase iNAV 9200 was designed for multiple broadband applications, to perform cost-effective bridging and routing between OC-3/STM-1 and OC-12/STM-4 and Fast and Gigabit Ethernet networks. In this particular configuration, the iNAV 9200 bridges the multicast IP packets over Ethernet to ATM PVCs that are fed into the Calix C7, which sends video to ADSL modems connected to set top boxes at the end-user sites.

The Calix C7 is a packet-based Ultra-Broadband Loop Carrier (UBLC) platform and is this configuration is connected to a SONET backhaul of ATM OC-3 links. "In order to grant service providers a higher level of assurance that this selected solution set will operate effectively under production conditions and in scale, we conducted interoperability testing with both Interphase and Minerva," said Rick Johnston, Calix Vice President of Business Development. "The iNAV 9200 from Interphase allows our customers cost-effective deployments of the C7, because it is a straight-forward solution with a price point much lower than traditional alternatives."

The Minerva VC8000 converts video to multicast IP video streams over Ethernet, and in this configuration feeds the video over IP to the Calix C7 through the iNAV 9200. "Calix is a very proven, cost-effective solution for delivering video to the IOC marketplace. Our partnership with Interphase allows us to have an elegant, yet simple integration to provide video over IP over ATM," said Andy Crowe, Vice President of Worldwide Field Operations. Minerva Networks recently announced its new transrating technology, which will provide rate-limited digital streams to the iNAV 9200.
