AT&T Corp’s Marietta, Georgia-based Tridom Inc appears to have won a deal that picks up significant parts of the IBM Corp Sirena-3 $150m contract that never was. Tridom says it has signed a master purchase agreement for an AT&T Tridom Clearlink CL-400 Very Small Apeture Terminal satellite communication system. The deal, worth $20m, will see the creation of a Moscow hub that will support up to 800 Very Small Apeture Terminal sites around the country. Sirena has been working on an airline ticketing, cargo reservation and tracking system for Russia or at least four years. Sirena is made up of 48 organisations from the airline industry of the former Soviet Union. In 1991 it agreed with IBM a $150m project but in October, after some equipment was delivered, the Sirena-3 project was dropped (CI No 2,519) due to problems with financing and also the diminishing number of domestic air passengers. AT&T Tridom has also managed to secure a US Eximbbank bank guarantee for the project – announced during P resident Yeltsin’s visit to the US at the end of September.
