Multiplexer use X.25 protocol, while statistical multiplexers use the Alpha protocol
Statistical multiplexers need buffers while multiplexers do not need buffers
Multiplexers often waste the output link capacity while statistical multiplexers oppose its use
Multiplexers use Time Division multiplexing (TDM) while statistical multiplexers uses Frequency division multiplexing (FDM)
