I did some quick looks into a couple of books I have to see what they say.
Scott Keagy's book "Integrating Voice and Data Networks" has nothing to say about FXO and FXS in particular. The "Cisco Call Manager Fundamentals" book makes the rather brief assertion that "FXS ports provide connection to loop-start or ground-start telephone lines, ... ( PBX ) ports, and other analogue telephone devices. FXO ports provide connection to central office ports or PBX extensions" Interesting wording, and seems to apply to what I was told. Learn something new, some better way to think about things, every day.
