Hi,


FXS card  = plug to regular phone

FXO card = plug to phone line


The trick I use is:
FXO with a 'O' as in Office.
This is where you plug your phone
A FXO card emulates a phone (receives power)


FXS with 'S' as in (public) Switch
This is the part that gives power
A FXS card emulates a switch (gives power)


Plugging 2 FXS elements together is not a good idea
Plugging 2 FXO elements together will not work but no problem otherwise
