An Asterisk FXO interface connects to a phone line. So it has to detect ringing voltage, answer (take the "phone off hook", ie loop the line) and so on. An Asterisk FXS interface has to connect to a phone. So it has to make ringing voltage, detect if the phone is taken off hook or put on hook, detect tone or pulse dialling and so on.
