FXS is a station port. It provides battery(power) to the line for any
devices hanging off of it. 

FXO is a device port. It is the device on a line that already has
battery(power).

The port on the back of your telephone is a FXO port. The jack on the
wall could be considered your end of the FXS port. FXS ports connect to
FXO ports. You can only have 1 FXS port per line, but you can have
multiple FXO ports on a line.
