SPRINT FRAME RELAY SWITCHES BREAK NEW GROUND IN PERFORMANCE

 SPRINT FRAME RELAY SWITCHES BREAK NEW GROUND IN PERFORMANCE
 ATLANTA, May 20 /PRNewswire/ -- Sprint (NYSE: FON) today introduced a new line of dedicated frame relay switches that offer higher performance and a lower price than comparable frame relay switches now available.
 Sprint's new TP4900 F-Series offers the processing power and sophisticated frame relay features of its flagship TP4900 line -- the same data switches used worldwide in private data networks and in Sprint's X.25 and frame relay global data networks.
 The TP4900 F-Series can be used to interconnect Local Area Networks (LANs), front-end communications processors and X.25 packet switches via high-speed frame relay technology. The units may be used as CPE access to public frame relay networks or as backbone switches in private or public networks.
 Depending upon the specific model, the F-Series switches can deliver a sustained throughput ranging from 7 Mbps to 40 Mbps of user data through up to 28 T-1 (1.544 Mbps)/E-1 (2.048 Mbps) ports (over 800 channels). All models offer optional common logic, line card, and power supply redundancy as well as a local software reload option.
 The TP4900 F-Series complements Sprint's standard TP4900 products, which also provide frame relay. The TP4900 differs from the F-Series because it supports high-speed (2 Mbps) X.25 packet switching or a combination of both frame relay and packet switching.
 "The F-Series is priced very competitively against other dedicated frame relay switches," said John Holmblad, vice president and general manager of Network Systems for Sprint International, Sprint's global telecommunications subsidiary.
 "Since it supports frame relay exclusively, the F-Series can offer the same carrier-grade power and features of the PDN-proven TP4900 at a substantially lower price," he said.
 The frame relay software used in both the TP4900 F-Series and the standard TP4900 provides full support of CCITT and ANSI frame relay standards, including recent standards for management signalling and congestion management. It provides sophisticated congestion avoidance and management, Burst Bandwidth Trunking for superior handling of bursty traffic, and a low-overhead trunk protocol using variable length "sub-frames." The software also delivers detailed, carrier-grade accounting and statistics.
 Like Sprint's TP4900 line of packet switches, the TP4900 F-Series is designed and manufactured by Sprint at its Mount Laurel, N.J., manufacturing facility. Sprint has been shipping TP4900 frame relay switches since June 1991, and to date has supplied the equivalent of over 6,000 DSO ports.
 Sprint is a diversified international telecommunications company with $8.8 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.
