All I know (others will have to fill in the blanks):

V.21:     CCITT standard for 300 bps modems.
V.22:     CCITT standard for 1200 bps modems.
V.22 bis: CCITT standard for 2400 bps modems.
V.32:     CCITT standard for 9600 bps modems.

MNPx:	  MNP = Microcom Networking Protocol, a modem error-correction
          protocol.

CCITT:  Consultative Committee International Telegraph and Telephone.
        An organization established by the United Nations to develop
        worldwide standards for communications technology.
