The seventh plenary assembly of the International Telegraph Consultative Committee (CCIT) of the International Telecommunication Union met in Arnhem, Netherlands, from June 5 through 13, 1953, under the chairmanship of Mr. van der Toorn (Netherlands). Most of the work of the session was carried on in study groups on the following subjects: 1) general telegraphy, 2) technical aspects of the establishment, operation and maintenance of telegraph channels, 3) technical aspects of telegraph apparatus, 4) vocabulary, symbols and classification, 5) phototelegraphy and facsimile, 6) technical aspects of switching in the service of start-stop apparatus, 7) European telegraph network operated by start-stop apparatus, 8) operational methods and quality of service, 9) services offered to users and rates other than telex rates, and 10) international service of telegraph subscribers and rates for such service. At the request of the Buenos Aires Plenipotentiary Conference of ITU, CCIT considered the possibility of amalgamating itself with the International Telephone Consultative Committee (CCIF) and concluded, by a vote of 16 to 11 with 1 abstention, that such a course would not serve the best interests of ITU. CCIT decided to hold its eighth plenary assembly in Geneva in the first half of 1956.
