Interphase Creates Communications Appliance for Converging Networks

9/4/2003 - Interphase Corporation (NASDAQ: INPH), an international supplier of next-generation networking technologies, announced the iNAVTM 9200 Multiprotocol Gateway Solution, the flagship product in a new series of specialized communications appliances. The first of its kind on the market, the iNAV 9200 functions as a standalone gateway that bridges multiple communications protocols for converging networks.

The iNAV 9200 Multiprotocol Gateway Solution is an intelligent, stand-alone 1U system designed to unite networks that lack a common communications language by interworking, or translating, different network protocols. Network convergence is a recurring challenge in today’s communications networks, which is driven by the carriers’ need to both satisfy the end-user demand for communicating across multiple network mediums and consolidate network infrastructure for cost control. The legacy circuit-switched communications infrastructure is slowly evolving to packet-based technologies, such as Internet Protocol (IP), but most carriers would prefer to migrate networks to next generation technologies to extend the lifespan of existing equipment rather than discard previous infrastructure investments. Interphase expects the iNAV 9200 to play a key role in this transition by serving as a link between dissimilar network technologies while also supporting packet-based services that will future-proof today’s deployments from obsolescence in the foreseeable future.

Alternative solutions on the market today that perform protocol processing and interworking are generally costly, large-scale platforms that consume a larger physical footprint and fulfill multiple secondary functions. Powered by the WinPath® Packet Processor from Wintegra, the iNAV 9200 yields multimillion packet processing per second, a substantial performance improvement over comparable platform-based alternatives. The compact, 1U design conserves space at the network point-of-presence (POP), saving service providers a significant amount of equipment real estate. In addition, the iNAV 9200 offers substantial cost of ownership savings over traditional multi-slot gateways since Interphase offers comparable gateway functionality at a fraction of the price. These cost and real estate savings, combined with the significant performance improvement over other gateway options, enables the iNAV 9200 to offer up to a five-fold improvement in performance/price ratio over legacy solutions for converging circuit-switched and packet networks.

Although the iNAV 9200 is application-ready, it is a private label solution shipping via Interphase telecom original equipment manufacturer (OEM) customers for deployment in carriers’ access networks. Interphase OEM customers can offer it to the service providers as a standalone unit or alternatively as a rack mountable component in a larger system. The iNAV 9200 is designed specifically for use in broadband access applications that often require a gateway function including Digital Subscriber Line Access Multiplexer (DSLAM), cable headend (Cable Modem Termination Systems (CMTS)), and fixed wireless (Local Multiport Distribution Service (LMDS)) applications. The iNAV 9200 suits a broad array of additional application environments as well, where it can operate as a standalone multiservice switch or a media gateway, and can also be used to perform packet routing/classification, ATM switching, or ATM Segmentation And Reassembling (SARing). OEMs will have options for multiple circuit-based interfaces including T1/E1/J1, T3/E3, OC-3/STM-1, and OC-12/STM-4, and secondary packet-based interfaces include Fast Ethernet and Gigabit Ethernet.

Interphase is also developing additional compact gateway solutions for bridging other network protocols, such as SS7 and Ethernet, and a compact access multiplexer to ‘groom’ DS0 channels and consolidate carriers’ point-of-presence backhaul lines.

“We are very excited about the launch of the iNAV 9200 appliance,” said Greg Kalush, President and CEO of Interphase Corporation. “Aside from being an important milestone in the realm of gateway technologies, the appliance bears a common software interface to that of the iNAV Communications Blades, our line of embedded board-level communications subsystem building blocks. This will allow OEMs to leverage experience with either the iNAV boards or iNAV appliances across a variety of application architectures, including multi-slot platforms, rack-based systems, or in the standalone network node format as provided by the iNAV 9200. We are unquestionably delivering on our promise of making a significant impact on our customers’ time-to-market and in helping our OEM customers better serve their customers.”

“We cannot overstate the impact that we believe the iNAV 9200 will have on carrier infrastructures,” said Kobi Ben-Zvi, President, CEO, and founder of Wintegra. “The Interphase engineering team has fully utilized the ATM-Ethernet interworking capabilities of our WinPath processor in their gateway designs, and they have employed our chipset in a unique, application-ready appliance format that will address OEM time-to-market issues brilliantly. The iNAV 9200 is a ground-breaking advancement in performance, affordability, and simplicity for converging network infrastructures, and we are proud to be a part of the driving force behind this landmark innovation. Interphase and Wintegra have been engaged in a close partnership for several years now, and in that time Interphase has proven itself to be a true innovator in resolving communications technology bridging issues that many OEMs and carriers face today—precisely the function that we designed the WinPath to power. Interphase and Wintegra have truly achieved our mutual goal of significantly improving upon legacy alternatives on the market today.”

Preliminary versions of the iNAV 9200 are now available, and the product will be shipping in OEM quantities Q4 2003.
