V.32bis - The standard that came after V.32 which increased the speed from 9600 baud to 14.4 Kbits per second.
V.34 - This was a dramatic improvement for modem communications. It doubled the top speed of the V.32bis standard to 28.8Kbps.

V.42 - The name given to the standard for transmitting at 2400 baud.
