Press Contact Information

FRAMINGHAM, Mass. - April 7, 1999 -- Natural MicroSystems (NASDAQ:NMSS), the technology leader in Open Telecommunications™, today announced that Linux drivers are now publicly available through the open-source code model for its Alliance Generation® DSP (digital signal processor) boards. Developers can use these drivers to build a wide range of telecommunications applications on Linux – from Web-enabled call centers to IP telephony gateways and speech recognition systems.

The announcement reflects Natural MicroSystems’ commitment to address the immediate needs of the rapidly growing Linux community, which is accustomed to employing open-source code for software development. Source code for the Alliance Generation® DSP boards can be obtained via the Web at

"Our method of supporting the Linux community is actually quite unconventional for the telecommunications industry," stated Brough Turner, senior vice president of technology at Natural MicroSystems. "Typically, when a company moves to support Linux, it ports its existing code, but ships only binary – not source code – for its product. By distributing the source code for our software, Natural MicroSystems is providing Linux developers the tools they need, and is doing so via their medium – the Web. Our actions will augment the existing pool of open-source software available to Linux developers, ultimately speeding time-to-market."

Linux and the Telecommunications Market

Support for the Linux community is a logical move for telecommunications equipment providers. This is due, in part, to the fact that UNIX, the operating system upon which Linux is based, has a rich history in telephony devices and applications because of its AT&T/Bell Labs heritage. Linux provides the reliability and stability benefits of UNIX with additional advantages:


Beta versions of a Linux driver for Natural MicroSystems’ Alliance Generation products and a beta version of Natural MicroSystems’ CT Access™ for Linux are currently available via the Open Source for Open Telecom Web site at CT Access is a modular run-time and development environment for voice, fax and call processing applications. Source code for these drivers under Linux and other operating systems is also available at this site.

In addition to providing the above-mentioned source code for Linux, Natural MicroSystems provides the complete source code for its circuit-switching and CompactPCI "hot-swap" software at the site. The company also offers NaturalEdge consulting, support, integration, and testing services for Linux developers who want to accelerate development and deployment of applications.

Natural MicroSystems: A Legacy of Leadership in Open Telecommunications

Natural MicroSystems has a strong record of support for open telecommunications. The company recently launched Open Source for Open Telecom, a global initiative designed to expedite the telecommunications industry’s migration to standards-based hardware and software solutions through increased access to open-source software. (See news release, "Natural MicroSystems Launches Open Source for Open Telecom Initiative," February 26, 1999.) Natural MicroSystems was also instrumental in establishing Multi-Vendor Integration Protocol (MVIP™), the de facto hardware and software architecture standard for platform interoperability and telephone switching. In addition, the company originally proposed H.100, another interoperability protocol.
