  2. 1837 Invention of the first electric telegraph 1844 Samuel Morse sent his first public message over a telegraph Iine between Washington and Baltimore 1865 Foundation of the International Telegraph Union by twenty States 17 May with the adoption of the first Convention. First Telegraph Regulations. 1876 Alexander Graham Bell patents his invention of the telephone 1924 Paris - Creation of CCIF (International Telephone Consultative Committee) 1925 Paris - Creation of CCIT (International Telegraph Consultative Committee) 1927 Washington - Creation of the CCIR (Intl. Radio Consultative Committee) 1932 Madrid - Plenipotentiary Conference. Telegraph Union changes name to International Telecommunication Union 1947 ITU becomes a Specialized Agency of the United Nations 1956 Geneva - CCIF and CCIT merged into CCITT (International Telegraph and Telephone Consultative Committee) 1992 Geneva - Plenipotentiary Conference. Creation of 3 Sectors: ITU-T replaces CCITT, ITU-R replaces IFRB, CCIR, and ITU-D replaces TCD ITU Landmarks

New relationships betweenForums/Consortia and ITU-T

  41. “Consensus: after WTSA-2000, the ITU-T procedures are now very streamlined and efficient so that any perception of slowness can no longer be attributed to the ITU-T methods…” • “fully recognized that Sector Members have a significant leadership role in the ITU-T technical standardization activities…” • “ITU-T is and should remain the unique worldwide venue for industry and governments to work together in developing, providing and promoting global consensus-based telecommunication requirements and standards for the Information Society” • Welcome you in ITU-T! • ********** Industry Views on ITU-T Martigny, February 2001
