    (ITU) ITU-T, the telecommunication
   standardisation sector of ITU, is responsible for making
   technical recommendations about telephone and data (including
   fax) communications systems for PTTs and suppliers.  Before
   1993-03-01 ITU-T was known as CCITT.  Every four years they
   hold plenary sessions where they adopt new standards; there
   was one in 1992.

   ITU works closely with all standards organisations to form
   an international uniform standards system for communication.
   Study Group XVII is responsible for recommending standards for
   data communications over telephone networks.  They publish the
   V.XX standards and X.n protocols.  V.21 is the same as
   EIA's EIA-232.  V.24 is the same as EIA's EIA-232C.
   V.28 is the same as EIA's EIA-232D.
