Olympics IT outsourcer Atos has said it successfully completed its first live batch of tests for the London 2012 Olympics.

Atos and its technology partners this week tested the communications, media, sports and technology security systems.

One rehearsal simulated periods of the London 2012 competition schedule, testing simulated "games-time conditions" to complete the tests.

Michele Hyron, Atos chief integrator for London 2012, said: "By the end of the testing phase we will have undertaken more than 200,000 hours of testing of the IT system, which will process 30 percent more information than at any other games in history."

During the games the IT team will number 3,500 "business technologists". Atos has been keen to promote the role of IT behind the games and recently hired IAS b2b Marketing to boost the role of these "business technologists".

Reuben Webb, creative director at IAS, last month told The Drum marketing website: "We developed the category redefining positioning 'The Business Technologists' which struck just the right note with a recession-hit market needing information technology to become properly business focussed."

Webb said: "The Business Technologists was also a major coup for internal branding and was celebrated as a culture redefining moment. At last the humble IT guy could hold his head high as a Business Technologist."

Those humble IT guys will be responsible for 900 servers, 1,000 network and security devices and over 10,000 PCs. A final technical rehearsal of the system will take place in May.

Other companies involved in the IT behind the games include Acer, Panasonic, Samsung, BT, Airwave and Cisco.
