Lemme guess....you're an undergrad who's got an assignment to be completed in a hurry? Dude, these are detailed topics...

Anyway, PCM is a tecchnique used to convert an analog signal to digital, then MUX this dig. signal with other dig. signals and transmit them over a T1 / E1 line. PAM is the first stage in achieving a PCM signal.
