Natural MicroSystems Corporation

PRODUCTS AND SERVICES

The principal functions addressed by our products include connectivity to communications networks, call processing, real-time media processing, and media stream protocol processing. These capabilities are accessed through a series of application programming interfaces that expose the hardware and firmware functions to the developer for the purpose of creating an application or system.

Our products are developed for global markets and allow customers to integrate their applications and systems into the IP network and the PSTN. Our products are compatible with signaling protocols and are approved for use in many countries. In order to have a presence in the fastest growing and largest international markets, we use our technological expertise, open architecture, and familiarity with international regulatory requirements to obtain the approvals required for use of our products in principal foreign markets. Our products have been incorporated into products sold to end users in over 40 countries.

Our products are open, accessible, standards-based, layered, network protocol-and operating system-independent, modular and scalable. These features offer developers significant reduction in time and effort when developing sophisticated applications and systems.

Convergence Generation. The Convergence Generation product family, currently in field trials, consists of software and hardware components configured specifically for convergence-centric systems and applications. This product family is designed for an Intel StrongARM co-processor and Texas Instruments (TI) C54x family of digital signal processors. We believe the architecture is extensible to hundreds of ports per slot and capable of integrating high-density IP network and PSTN interfaces including T3 and OC-3. We believe this product family offers the best price performance for converged network solutions such as IP telephony gateways and IP media servers.

PolicyPoint. The PolicyPoint product family, currently in field trials, consists of software and hardware components that provide reliable, cost-effective, predictable and consistent transport of voice, video and data over packet networks. The product family is designed for the TI C6x family of digital signal processors and does not require a host processor. It provides connectivity to any ATM WAN while controlling network and application specific usage and performance. The PolicyPoint architecture offers a soft-ASIC capability that allows for the integration of additional WAN protocols including frame relay, point-to-point protocol, multi-protocol label switching and differentiated services. We believe the architecture is extensible to higher density LAN and WAN interfaces. We believe PolicyPoint’s architecture delivers a compelling price performance advantage.

Alliance Generation. The Alliance Generation is a proven product line with a field history of over eight years. It consists of software and hardware components configured to meet the needs of enterprise and enhanced services applications for circuit-switched environments. This product family is designed for an Intel x86 co-processor and TI C51 or TI C549 families of digital signal processors. The port densities offered range from 2 to 120 ports per slot and the Alliance Generation product line is differentiated from competition due to its unique extensibility. The product family enables systems to maximize resources, thereby reducing costs.

Intelligent Networks/SS7. The Intelligent Networks/SS7 product family consists of software and hardware components that provide a complete suite of intelligent networking protocols for PSTN connectivity. The product family is designed for the Motorola 68xxx family of processors. It allows for a full implementation of the SS7 protocol stack with access at all layers and contains a set of switch-specific and high availability extensions that meet service provider requirements and facilitate worldwide deployment and interoperability.

Natural Access Software. The Natural Access Software suite consists of CT Access with Natural Call Control, NaturalFax, ActiveAG, TAPI support, ISDN, Channel Associated Signaling and high availability extensions. This suite was designed as the development and run-time environment for the Alliance and Convergence Generation product families and provides for the rapid development of high performance, scalable applications. Natural Access allows developers, working with common programming languages and different programming models, independent of host platforms and operating systems, to implement applications and systems requiring communications functionality.
