 CARRIERS IN NORTHERN EUROPE AND ISRAEL CHOOSE SPRINT'S
 FRAME RELAY SWITCHES
 -- Sprint Also Announces Availability Of Frame Relay
 Service To U.K. --
 SAN FRANCISCO, Oct. 28 /PRNewswire/ -- Sprint's frame relay switching technology will be used by value-added network service providers covering the U.K., Sweden, Germany, the Netherlands, Belgium and Israel, the company today announced at the INTEROP 92 Fall, currently underway.
 Sprint also announced the availability of its public frame relay service to the United Kingdom which will be based on its U.K. access node. The company will begin taking customer orders immediately for U.K. service at access speeds up to 256 kbps.
 Sprint's Frame Relay Service
 Frame relay is a high-speed, bandwidth-on-demand service designed for the "bursty" communications between today's widespread Local Area Networks (LANs) and geographically dispersed SNA networks.
 Sprint -- unlike other frame relay service providers -- offers a flexible committed information rate (CIR), the sustained minimum throughput rate at which traffic flows through the network. Sprint's is the only service that permits bursts above a customer's requested CIR up to the full access channel on a sustained basis.
 The CIR feature provides the most cost-effective frame relay service since customers are only charged for the minimum throughput rate that they select. CIR also ensures that important information will always go through, especially during periods of peak usage and traffic density.
 "Sprint's new service to the U.K. is the beginning of a frame relay global deployment within our international network," said Leigh Saunders, director of Strategic Services for Sprint International, Sprint's global telecommunications subsidiary.
 "We also expect that the value-added networks affiliated with Sprint will provide joint services by similarly deploying Sprint- developed frame relay technology, thus expanding their reciprocal global reach," she said.
 Bezeq, Unisource To Deploy Sprint Frame Relay Technology
 Bezeq -- Israel's telecommunications administration -- and Unisource Business Networks, the pan-European joint venture formed last year between PTT Telecom Nederland BV and Sweden's Televerket, both have selected the Sprint-manufactured TP4900 cell-based switch as the platform for their frame relay networks.
 Unisource Business Networks, headquartered in Frankfurt, will offer frame relay services to customers throughout Europe via the new Sprint TP4900 frame relay network. The network initially will consist of five major switching centers located in London, Amsterdam, Frankfurt, Brussels and Gothenburg.
 Unisource Business Networks will expand its pan-European network services in the coming months. This will include France, Norway, Denmark, Finland, Italy, Spain and Switzerland. Further global coverage will be offered during 1993.
 In Israel, Bezeq plans to enhance its existing advanced data communications products and services by deploying a public frame relay service. With the support of Tadiran -- Sprint's distributor in Israel -- Bezeq is currently installing a three-node frame relay network at switching centers in Tel Aviv, Jerusalem and Haifa.
 Bezeq plans a live demonstration of the service at the I.L.A. trade show, Nov. 3-6 in Tel Aviv. Bezeq plans to implement frame relay service over its existing Sprint-manufactured national public data network in 1993.
 Sprint's TP4900 cell switch is the same technology deployed by the company in its own global frame relay network. It offers full support of CCITT and ANSI frame relay standards, including recent standards for management signaling and congestion management. It also supports implementation agreements for user-to-network and network-to-network interfaces adopted by the Frame Relay Forum, an emerging industry-wide standards body comprising the leading frame relay service providers.
 Unique features of the TP4900 include a Burst Bandwidth Trunking capability that accommodates extended traffic bursts, and a cell- switching trunk protocol featuring Sprint's exclusive Dynamic Cell Compression which greatly improves bandwidth efficiency and cost performance. The TP4900 also offers economical redundancy which allows a single processing unit to act as a backup for any other within a switch. Its carrier-grade features include detailed accounting and statistical reporting.
 "Sprint became the world's leading supplier of packet-switched data networks by designing switches with unparalleled performance, reliability and value," said John Holmblad, vice president and general manager for Private Networks for Sprint International, Sprint's global telecommunications subsidiary.
 "The cell-based TP4900 switch possesses those same attributes and has extended our X.25 leadership into the frame relay arena as well. The switch enables service providers to offer both technologies to their users and offers a straightforward migration path from X.25 through frame relay to broadband cell switching," he said.
 Unisource Business Networks and Bezeq also offer packet-switched data services through Sprint-provided X.25 networks. More than 40 PTTs and Value Added Network (VAN) providers around the world offer public data services via Sprint-supplied equipment, including Germany's INFO AG, Bezeq, Telekurs of Switzerland, Gulfnet USA in the Middle East, Canada's Unitel, Sprintel Venezuela, MLS of Italy, Sprint Networks in the former Soviet Union, and AOTC of Australia.
 Sprint's Frame Relay Leadership
 Sprint is the leading supplier of frame relay services and systems worldwide, to date having shipped switches and line cards which can support more than 26,000 ports. The company led in advocating and developing frame relay standards, designed the industry's most rigorous frame relay certification program, and is the only public service provider to also manufacture its own frame relay switches -- the TP4900 and TP4900F Series.
 Sprint (NYSE: FON) is a diversified international telecommunications company with $9 billion in annual revenues and the United States' only nationwide all-digital, fiber-optic network. Its divisions provide global long distance voice, data and video products and services, and local telephone services to more than 4 million subscriber lines in 17 states.
