How does an acoustic coupler work?

The first acoustic couplers used a telephone handset and transmitted at speeds of up to 300 baud. To transmit information the acoustic coupler converts data into sound signals, sends those signals over the phone line, and then the receiving acoustic coupler interpreted those signals.
