V.32ter
     
        An extension of the {ITU-T} {V.32bis} {modem} {protocol}.
        While waiting for {V.34}, many {modem} manufacturers decided
        to extend V.32bis to 19.2 kbps.  This was known as V.32ter
        which some {marketroid}s rechristened V.32 terbo which is not
        only misspelled but misses the fact that V.32ter means the
        third revision of V.32.
