The itu telecommunication standardization sector (itu-t) is one of the three sectors of the international telecommunication union (itu). It coordinates standards for telecommunications. The international telegraph and telephone consultative committee (ccitt, from french: comité consultatif international téléphonique et télégraphique) was created in 1956, and was renamed itu-t in 1993. Itu became a United Nations specialized agency in 1947.
