AT&T CORP said a software glitch in switching equipment supplied by CISCO SYSTEMS INC caused last week's massive failure in its high-speed data network that serves large business customers. AT&T said the problem began when a computer command was issued to upgrade software code in one of the network switch's circuit cards. This created a faulty communications path that generated a large volume of administrative messages to other network switches. As a result, the other switches quickly became overloaded and stopped routing data from customers' applications for periods ranging from six to 26 hours before the network was fully restored.
