ITU-T
The ITU Telecommunication Standardisation Sector (ITU-T), is a permanent organ of
the International Telecommunication Union. The ITU-T is responsible for studying
technical, operating and tariff questions and issuing Recommendations on them with a
view to standardising telecommunication on a worldwide basis.
As a consequence of a reform process within the International Telecommunication
Union (ITU), the CCITT ceased to exist as of 28 February 1993. In its place the ITU
Telecommunication Standardisation Sector (ITU-T) was created as of 1 March 1993.
