Samsung To Use JTCAP Signalware From Ulticom For 3G Wireless Services; New Signalware programming interface with Java Technology will speed application development.

Business Editors/Hi-Tech Writers

MOUNT LAUREL, N.J.--(BUSINESS WIRE)--March 19, 2001

Ulticom, Inc. (NASDAQ:ULCM) today announced that Samsung Electronics, Co. Ltd. is developing a new third generation (3G) wireless Service Control Point (SCP) using Ulticom's Signalware(R) JTCAP(TM) API, a Java(TM) technology-based TCAP API (application protocol interface).

The effort from Dallas-based Samsung Telecommunications America (STA) and Samsung Electronics in Korea development groups will create an end-to-end solution with voice, data and video capability in a 3G wireless architecture.

Samsung's core network engineering teams are developing products based on the UMTS standard for the global market place. The 3G products under development include a Mobile Switching Center (MSC), Serving and Gateway GPRS Support Nodes (SGSN and GGSN), a Service Control Point (SCP), and a Service Management System (SMS). All core network products utilize Samsung's next generation carrier class platform that consists of commercial hardware and software enhanced with distributed processing, fault tolerance, flexible service logic, data-driven OAM&P, and multimedia call processing software features.

The MSC architecture is based on Softswitch technology, which provides a smooth upgrade path to the all IP network as advocated by the UMTS standards. The MSC and SCP products support a service execution environment for call processing services developed with Samsung's JAVA based Service Creation Environment (SCE).

Jim Bunch, Vice President of Engineering of Network Systems Lab for STA said, "One reason we selected Ulticom's SignalWare and JTCAP products was their early adoption and commitment to Java and JAIN technologies. Samsung's next generation product strategy places heavy emphasis on flexible service creation of voice, data, and multimedia services. Java and JAIN technology provides us the flexibility necessary to achieve our product strategy."

As a new feature to Signalware, the JTCAP API enables the next generation of network applications for popular services to be developed by application providers independent of the underlying voice and data network. By combining the programming ease of Java with the carrier-grade reliability, scalability and performance of Signalware, Ulticom helps developers like Samsung rapidly build premium services.

Shawn Osborne, President and CEO of Ulticom, Inc. said, "We are pleased to work with forward-looking companies like Samsung who are creating the infrastructure for the delivery of the next generation of wireless services. The powerful combination of Signalware and the programming ease of Java will enable Samsung's new wireless services to be quickly deployed and seamlessly enhanced as demand for these services increases."

On a daily basis, Signalware interworks thousands of carriers, connects millions of subscribers and processes billions of transactions. In real-world networks, Signalware is relied upon to provide a host of revenue-generating business and consumer services. Signalware enables communication service providers to offer Intelligent Network services such as voice-activated dialing, prepaid calling, caller ID and text messaging. Signalware also enables voice and data networks to seamlessly integrate, allowing converged network services such as Internet off-load, voice over the Internet, and Internet call waiting.

"Samsung's selection of Ulticom's JAIN-based JTCAP API demonstrates the advantage standards-based offerings have in this very competitive market. With the flexibility and portability of Java and the broad industry support of JAIN, Samsung will have excellent investment protection and diverse options as they roll out next generation services. We're pleased to see the JAIN standards effort bearing fruit," said Ann Wettersten, vice president of the Wireless Business Group at Sun Microsystems, Inc.

The Signalware JTCAP API is the first to be certified as conformant with the JAIN(TM) TCAP API specification standards established through the Java Community Process(SM). The Java Community Process program was developed by Sun Microsystems, Inc. and other industry members for the development and revision of Java API technology specifications.

The JAIN APIs enable the integration of Internet (IP) and Intelligent Network (IN) protocols by providing a new level of abstraction and associated Java interfaces for service creation across Public Switched Telephone Network (PSTN), packet (e.g. IP or ATM) and wireless networks.

The JAIN Initiative:

A Service Provider's Extension to the Java Platform Organized by Sun in 1998, the JAIN initiative addresses the needs of next-generation telecom networks by developing a set of industry-defined APIs for Integrated Networks. Network services today are typically built using proprietary interfaces that inhibit the marketplace for new services.

Members of the JAIN community have joined forces to define open APIs based on Sun's Java platform, thus allowing service providers to rapidly create and deploy new flexible, revenue-generating services. The development of JAIN specifications is spearheaded simultaneously in Asia, Europe, and the U.S. To date, more than 75 of the communication industry's leading hardware providers, network equipment providers, protocol providers and service providers have joined the JAIN initiative.

The JAIN community also coordinates with other broad-based industry groups like the Parlay Group, the International Softswitch Consortium and 3GPP to provide quality industry-supported community extensions for the Java platform.
