Natural MicroSystems Unveils New PowerAccess Architecture: Breakthrough High Density and Cost per Port as Low as $30 for Broadband Access Switches and Gateways Tuesday 16 January 2001 PDF Print Products Based on Advanced ASIC Designs Now Available Natural MicroSystems (NASDAQ: NMSS), the technology leader enabling a new era of communications, is today introducing its revolutionary PowerAccess architecture-capable of supporting over ten thousand ports in a single CompactPCI® chassis-and reducing the cost to produce broadband access switches and access gateways to an unprecedented $30 per port. At the same time, NMS is announcing the availability of the first PowerAccess products based on this architecture. The PowerAccess architecture is the foundation of a new family of high-capacity hardware and software platforms providing the base for lower-cost, higher-density network access offerings to appeal to network operators and service providers, who need more economical ways to deliver broadband services in today's revenue-conscious environment. Communications equipment developers can rapidly create more compelling offerings when they use NMS' PowerAccess technology inside their own access switches and access gateways, including voice-over-Internet Protocol (VoIP) gateways, voice-over-digital subscriber line (VoDSL) gateways, voice-over-wireless local loop (VoWLL) gateways, and broadband access switches. In the case of broadband access switches, PowerAccess technology will enable developers to build solutions competitive with the vastly more expensive Class 5 telecommunications switches. Three NMS platforms are the first to take advantage of the PowerAccess architecture, implemented within a new PowerAccess Bus for each platform. Initial NMS products enabled with PowerAccess technology are: the PA HYPER-T3 DS-3/STS-1 broadband access adapter (now shipping), the new high-capacity PA-16 T1/E1 broadband access adapter and a new PA200 voice over broadband ATM platform. NMS is announcing the PowerAccess architecture and the availability of the initial product line offerings in conjunction with its exhibit and sponsorship at the VoDSL Europe 2001 Conference and Exhibition in Paris, France this week (January 16-19). Cost per Port and High Capacity Are Boons to Profit-Conscious, Growth Markets Business and consumer demand for lucrative voice-over-IP and voice-over-broadband services, coupled with high-speed access technology, come together in a largely untapped market with huge potential. According to leading analyst firm Probe Research, Inc., voice over packet gateway port shipments will reach 9.2 million ports per year in 2002. In response, network operators and service providers continue seeking ways to fill the demand, while ensuring that the cost of new infrastructure and provisioning doesn't consume their profit margins. "The market opportunity associated with innovative voice-over-broadband services is one of the most important and promising areas in the emerging packet convergence industry," said Tom Valovic, Program Manager for IP Telephony at IDC. "By pushing the envelope for both port density and port cost, Natural MicroSystems' announcement will help to facilitate the deployment of these systems in today's cost-sensitive carrier environments." PowerAccess Bus Advances CompactPCI Capabilities "Higher port density is simply fundamental to reduce system costs for next-generation broadband switches and gateways," said Michel Laurence, vice president and general manager of NMS' Network Access business. "The PowerAccess architecture blasts through the barrier that until now has limited the scalability of the CompactPCI format. And importantly, we have retained all the best of CompactPCI-the openness and high availability that communications equipment suppliers and their customers require for fast time-to-market and reliable operation." To expand the capacity attainable with standard CompactPCI designs, NMS' PowerAccess architecture features the PowerAccess Bus-an external, parallel TDM (time division multiplexing) bus similar to the H.110 TDM data bus specified by CompactPCI. The PowerAccess Bus complements the H.110 bus by doubling the number of voice ports (that is, adding an extra 2,048 ports) to a CompactPCI chassis. In contrast to the H.110 bus, the PowerAccess Bus can be partitioned to connect groups of PowerAccess boards via cable between rear I/O connectors. This enables development of very high capacity gateways that can scale to more than ten thousand ports. First PowerAccess Products Detailed NMS is also announcing its first platforms to be equipped with PowerAccess technology. The award-winning PA HYPER-T3 DS-3/STS-1 broadband access adapter, announced last year, is immediately available with the PowerAccess Bus. The three new NMS products making their debut in Paris today are: · PA 16 T1/E1 access adapter. At 480 ports, this broadband access adapter features twice the capacity of any comparable product currently on the market. The 16 T1/E1 adapter will be available in March, 2001. · M100 Echo cancellation and compression option. A mezzanine module for both the PA Hyper T3 or the PA 16 T1/E1 access adapters. Using advanced DSP and ASIC technology, this option provides up to 672 ports of standard G.165 echo cancellation and 32 or 16 kbps ADPCM compression (G.726-16). Available in Q2, 2001. · PA 200 Voice over broadband platform. Based on high performance, second generation ASIC technology, this board and software platform delivers 2048 ports of TDM to ATM processing with an OC-3 network interface. Available in Q2, 2001.
