NTT Frame Relay Service Network Suffered Outage October 31, 1997 (TOKYO) -- Nippon Telegraph and Telephone Corp.'s Super Relay FR, a frame relay service network, suffered a serious outage. The network outage occurred Oct. 16 and it affected about 8,000 lines in the Osaka area, Nagoya and other cities in west Japan. The outage struck Super Relay customers as well as customers of NTT's open computer network (OCN), an Internet access service using a frame relay network for the backbone, and EBN, an IP service for businesses. NTT's frame relay service is used to connect enterprise local area networks (LANs). An Osaka-based corporate customer had its lines disconnected. The company utilizes the frame relay service for workshops held throughout Japan. Its lines to more than 100 of its business offices located across the country were rendered useless by the network failure. The Osaka company's lines connected to many local offices recovered quickly. But at five locations, communications remained disabled until the early evening. The company used ISDN lines for backup communications. Another customer with a nationwide business suffered an outage in its business hubs in western Japan. The cause was a problem with NTT's frame relay switches. NTT explained that an accident occurred and stopped the switches when hardware was being replaced to expand system capacity. Some customer routing information was apparently erased when the switches were restarted. NTT is analyzing the causes of the trouble. NTT could be installing new FR switches from ASND and Operator Error occured.
