Modems are generally classified by the amount of data they can send in a given time unit, normally measured in bits per second (bits, or bps). They can also be classified by the symbol rate measured in baud, the number of times the modem changes its signal state per second. For example, the ITU V.21 standard used audio frequency-shift keying, aka tones, to carry 300 bits using 300 baud, whereas the original ITU V.22 standard allowed 1,200 bits with 600 baud using phase shift keying.
