V.90

A standard for 56-Kbps modems approved by the International Telecommunication Union (ITU) in February, 1998. The V.90 standard resolves the battle between the two competing 56 Kbps technologies -- X2 from 3COM and K56flex from Rockwell Semiconductor. Both manufacturers have announced that their future modems will conform to V.90. In addition, most users who already purchased 56 Kbps modems will be able to apply a software upgrade to make their modems support V.90.
