ITU Telecommunication Standardization Sector (ITU-T) Standards are now freely available
ITU is the leading United Nations agency for information and communication technologies. The function of ITU-T is to provide global telecommunication standards by studying technical, operating and tariff questions. The results of these studies are published as ITU-T Recommendations.
ITU-T aims to continue to be recognized as the pre-eminent worldwide telecommunication standards body. As of March 2005, there are around 3100 Recommendations in force on topics from service definition to network architecture and security, from dial-up modems to Gbit/s optical transmission systems to next-generation networks (NGN) and IP-related issues.

Standards produced by ITU — ITU-T Recommendations — are now available without charge. The announcement follows a highly successful trial conducted from January−October 2007, during which some two million ITU-T Recommendations were downloaded throughout the world.
