IXC Selects DSC's Intelligent Networking Solutions: Competitive Carrier to Deploy IN Products for Customized Service Delivery.

DALLAS--(BUSINESS WIRE)--Sept. 10, 1996--DSC Communications Corporation and IXC Communications, Inc. today announced the signing of an agreement calling for delivery of DSC's intelligent networking (IN) systems. IXC plans to deploy multiple elements from DSC's A-INfusion(TM) product family. With these DSC systems integrated into its network, IXC can offer faster service delivery and more customized options for its customers throughout the United States.

IXC's contract with DSC calls for delivery of the A-INfusion Intelligent Service Peripheral (ISP), DSC's Service Creation Environment (SCE), and the MegaHub(R) STP-W/2. These products will be combined with IXC's embedded network of DSC DEX 600 tandem switches, with hubs in Dallas, Los Angeles, Atlanta, Philadelphia and Chicago. Together, DSC's systems will enable IXC to offer applications such as advanced 800/888 services, call routing and customized account codes to its subscribers.

"We needed a new platform for advanced services, and DSC's ISP provides us with a solution that fits our needs," said Ken Hinther, IXC's executive vice president of network operations and engineering. "DSC has proved that it can deliver the reliable products and customer support we need to maintain a first-class, coast-to-coast, all-digital telecommunications network."

Butch Charlton, DSC's vice president, public networks, said: "By using DSC's family of advanced intelligent networking equipment, IXC will be able to expand and improve its service significantly. The capabilities these new systems will bring to IXC, combined with their existing DSC-based network, are outstanding, since they increase the carrier's capability to respond to customer needs much more rapidly and efficiently. In effect, IXC will be able to tailor its network quickly for more individual service delivery."

DSC will provide IXC with its Intelligent Service Peripheral (ISP), the latest addition to DSC's A-INfusion product family. The ISP combines both Service Control Point (SCP) and Intelligent Peripheral (IP) functions in a single platform for cost-effective delivery of a broad range of intelligent network applications, including enhanced carrier-based services such as NOO/888 PIN translation or validation services. Whether an application requires a database lookup (an SCP function) as in a personal number service or requires voice processing resources (an IP function) for voice-activated dialing, the service can be deployed with a single system. The ISP platform also interfaces with the SCE function, providing a complete system for service creation, simulation and deployment.

To complete the intelligent network installation, DSC also is providing the MegaHub STP-W/2. With its high-performance packet switching capability, the STP-W/2 transmits Signaling System No. 7 (SS7) signaling messages for both basic and advanced services, such as call set-up, caller name and caller identification, and toll-free services (800 and 888).
