ECHELON is a name used in global media and in popular culture to describe a signals intelligence collection and analysis network operated on behalf of the five signatory states to the UKUSA Security Agreement. It has also been described as the only software system which controls the download and dissemination of the intercept of commercial satellite trunk communications. ECHELON, according to information in the European Parliament document, "On the existence of a global system for the interception of private and commercial communications" was created to monitor the military and diplomatic communications of the Soviet Union and its Eastern Bloc allies during the Cold War in the early 1960s. The system has been reported in a number of public sources. Its capabilities and political implications were investigated by a committee of the European Parliament during 2000 and 2001 with a report published in 2001, and by author James Bamford in his books on the National Security Agency of the United States. The European Parliament stated in its report that the term ECHELON is used in a number of contexts, but that the evidence presented indicates that it was the name for a signals intelligence collection system. The report concludes that, on the basis of information presented, ECHELON was capable of interception and content inspection of telephone calls, fax, e-mail and other data traffic globally through the interception of communication bearers including satellite transmission, public switched telephone networks and microwave links.
