Chambers apologized AT&T, part II Elsewhere, the impact of the network breakdown was uneven. Some businesses and institutions noticed slowdowns. These included Northwest Airlines, in its processing of reservations, and the American Red Cross, in the tracking of its blood supply. Many businesses suffered financial losses as a result, though only a few offered estimated Tuesday. Tele-Communications Inc., the cable television giant, pegged its losses at as much as $5 million -- resulting from the inability of TCI representatives who field requests for pay-per-view services, installation and repairs at 500 offices to log in to the company's central data base to get access to billing information or to process orders. The breakdown was something of a black eye for Cisco, which has been trying to sign up more phone companies as customers, breaking into the markets of Lucent Technologies Inc. and Northern Telecom Ltd. ''We view this interruption as unacceptable, and apologize to our joint customers who have been affected,'' John Chambers, president and CEO of Cisco, said in a press release Tuesday. ''The Cisco team, together with AT&T, will continue to focus on this matter until we are convinced that all problems associated with this outage have been identified and resolved.'' In the aftermath of the outage, Cisco rushed two new pieces of its equipment to AT&T's switching offices in Albany, N.Y., and Cambridge, Mass., via a chartered jet, said Darryl Miller of FOB America, the company that delivered the equipment. The AT&T network that went down is called a frame relay network because of the the method it uses to handle data at high speeds. The data packets are sent almost instantaneously over fiber optic telecommunications lines and complex switches across the country. AT&T's frame relay network has 145 switching hubs, or nodes. Company executives said on Tuesday that the exact cause of the breakdown had not yet been determined. But one executive said that the problem began with a data transmission between the Albany and Cambridge hubs. The problem cascaded uncontrollably to the other hubs in the network, for some as-yet undetermined reason.
