GPT's Vistra Range of Products Use Embedded Software Solutions from Lynx Real-Time Systems.

SAN JOSE, Calif.--(BUSINESS WIRE)--Oct. 1, 1997--Lynx Real-Time Systems, Inc. today announced that GPT, Ltd. has selected Lynx as their supplier of embedded operating systems for GPT's "Vistra" range of products for the System X Central Office (CO) switch.

Network operators today face a rapidly changing marketplace. Now, more than ever, customers expect new services - and improved service. The growing number of PC's and workstations is matched by companies' increased use of services such as file transfer, videoconferencing, document image processing and desktop multimedia. All this adds up to a huge increase in the load on the central exchange's "brain" - the processor. Today's exchanges need tomorrow's technology to cope with these new demands. GPT's new Vistra range of products (with the Lynx operating system) are set to meet these needs. The Vistra range of products go far beyond mere switch enhancement.

Following the lead of the computer industry, GPT is evolving System X from the centralized switch architecture of today to a distributed architecture using industry standard technology - providing economy, flexibility and reliability.

"After careful evaluation of many real-time operating systems, we selected the Lynx solution due to its strengths for highly-reliable telecommunications applications," said John Ward, Development Manager for the Vistra Core Software for GPT. "Lynx offered an embedded operating system that provides what Lynx calls "reliable processing" as well as standards compliance for portability, and deterministic real-time performance."

"The reliability of the Vistra range of products is of utmost importance. We required an embedded operating system that provided protected application address spaces. Lynx provides this through its 'reliable processing' feature which assures that an application cannot corrupt another application nor can it corrupt the operating system. Provision of this feature and the ability to meet our real-time performance requirements were key in our selection of Lynx," said Ward. "Compliance with industry portability standards (including Unix and POSIX) was also critical to the selection process. The Lynx solution provided us a powerful software environment and allowed us to purchase off-the-shelf software rather than to develop the necessary software."

"GPT's selection of the Lynx solution is yet another example of the strengths of our product and service offerings for the communications industry," said Dino Brusco, Vice President Marketing for Lynx. "The System X Central Office Switch uses the Lynx product in GPT's new Vistra range which will support the call chain processing of the CO switch. We will continue to focus our efforts on providing the right solutions for the communications marketplace."
