Lucent Technologies Chooses Operating System from Lynx Real-Time Systems for Multimedia ProductsLucent's MMCX is first product for new multimedia networks

WHO ELSE USES A LynuxWorks EMBEDDED OS?

SAN JOSÉ, Calif., April 23, 1996—Lynx Real-Time Systems, Inc. announced today that Lucent Technologies—formerly AT&T's systems and technology business—has selected LynxOS as the operating system for its MultiMedia Communications eXchange (MMCX) Server.

The MMCX is the first product to bridge the separate worlds of private voice and data networks. For the first time, the MMCX allows people to use all the familiar office telephone features—such as conferencing or transferring calls—on multimedia calls involving voice, data, image and video.

Lucent chose the LynxOS operating system for two reasons: the product's ability to support deterministic, real-time functionality, and the company's high level of support, service, and technical expertise. "The MMCX is state-of-the-art, requires multi-threading, and accomplishes many tasks simultaneously, like taking information from a LAN and transmitting it to a conference call on a PBX," said Joy Pinsky, general manager for the MMCX. "Customer expectations for multi-media applications—especially in the voice arena—make real-time functionality a must-have. Without it, quality of service would be totally unacceptable."

LynxOS is the only commercial operating system that delivers hard real-time performance while complying with POSIX® and UNIX® standards. To support complex applications, LynxOS fully supports the Microprocessor Memory Management Unit (MMU). This enables programmers to partition computing programs, thereby safeguarding processes in one area from defects or bugs in another.

"We're finding that communications engineers are the fastest-growing segment of the market turning from home-grown real-time operating systems (RTOS) to off-the-shelf RTOS solutions, like LynxOS," said Inder M. Singh, President and CEO of Lynx Real-Time Systems, Inc. "Programmers are more productive when they focus on developing complex applications, rather than worrying about creating an RTOS from scratch."

POSIX, an enabling standard for sophisticated applications

One of the key advantages to buying an off-the-shelf RTOS is that they are often in compliance with critical industry standards.

No other real-time operating system matches the degree of LynxOS' compliance to POSIX. IEEE's POSIX standard plays a key role in leading the embedded, real-time world toward open systems. It defines the industry's standard application programming interface (API) for UNIX, and provides the first standard API for real-time embedded applications.
