STRATUS SUPPORTS 20 MILLION MOBILE TELECOM SUBSCRIBERS WORLDWIDE WITH HOME LOCATION REGISTER

Fault-Tolerant Stratus Systems and Middleware at the Forefront of Innovative Telecom Applications

Marlboro, Mass., November 4, 1997 Stratus Computer, Inc. today announced that its systems now provide essential Home Location Register (HLR) capabilities to 20 million wireless telecommunications subscribers around the globe, making Stratus® systems the single most widely used computer-based platform for HLR.

HLRs are vital to the smooth operation of wireless telecommunications networks, because they handle two core functions: subscriber mobility management and subscriber data management. They store data such as subscribers' telephone numbers, current locations, and available supplementary services.

Because HLR applications must always be up and running, fault-tolerant Stratus Continuum® Series systems and the company's extensive family of standards-compliant telecommunications middleware - including the Stratus Intelligent Network Application Platform (SINAPTM) - have become a top platform choice among telecommunications service providers, application developers, and infrastructure suppliers.

"As the demand for mobile calling services continues to rise, telecommunications providers count on Stratus to deliver the reliable hardware and comprehensive telecom middleware that has proven so successful in many of the world's most innovative wireless networks," said John Scanlon, Vice President of Telecommunications Systems at Stratus. "Service providers find Stratus platforms unmatched for robust HLR operation in addition to other critical, intelligent network (IN) applications, such as local number portability. Wireless and wireline customers alike value our hands-on expertise in IN."

Supplying Leading-Edge Solutions Wireless networks are evolving to a distributed, software-driven model, notes Mark Lowenstein, Vice President of the Yankee Group's Wireless/Mobile practice. "Companies such as Stratus are providing the key building blocks for this model, enabling quicker development of enhanced services, and real-time access to customer data for a host of customer registration, authentication, billing, and customer care applications," said Lowenstein.

Among the international market leaders that have delivered HLRs powered by Stratus platforms is NEC in Japan, a major supplier of cellular and PCS (personal communications service) PCS systems to wireless service providers in Japan and worldwide.

In South Korea, LG Information and Communications Limited (LGIC) has developed Stratus-based HLR software used by PCS provider SK Telecom (formerly known as Korea Mobile Telecom). LGIC and Stratus recently launched a partnership to make an enhanced version of LGIC's standards-compliant IS-41C HLR available internationally.

Orange plc, a national digital wireless phone service provider in the United Kingdom, last month announced that it is ready to meet a December 1998 regulatory mandate for number portability. Orange's ability to quickly respond to the mandate is due to the Stratus-based IN platform that it originally deployed for its Service Location Register (SLR), an innovative implementation of subscription management and call processing.

Proven Telecom Middleware In addition to its fault-tolerant Continuum family of UNIX® systems, Stratus provides a suite of telecommunications middleware based on SINAP, the successful Signaling System 7 platform installed in more than 60 wireless and wireline providers' networks. Application developers and customers depend on this mature platform for HLR and local number portability (LNP) as well as short message service, caller name, voice messaging, prepaid calling, personal number, and other IN applications.

SCEnicTM software, the Stratus Service Creation Environment, builds upon the capabilities of SINAP to accelerate the development, testing, and deployment of continuously available IN solutions. Open, standards-based SCEnic products include SCEnic/Service Control Point (SCP), SCEnic/Service Node (SN), and SCEnic/Mobility.
