  V.90
       
           An {ITU-T} {standard} {modem} serial line
          {protocol} allowing download speeds of up to 56 {kbps} with
          upload speeds of 33.6 {kbps}.  {V.90} modems are designed for
          connections that are digital at one end and have only one


          digital-to-analogue conversion.
       
          As of 1998-02-06 the V.90 standard, formerly called V.pcm, has
          been given final approval by {ITU-T}.  On 1998-10-27 the ITU-T
          announced that approval of the V.90 standard was completed.
          Interoperability testing is complete or in progress for
          several modem manufacturers.  The V.90 standard reconciles two
          competing standards, {X2} and {K56flex}.
       
          The {ITU-T} has initiated the approval process for a new
          all-digital version of the protocol, to be known as {V.91}.
