Your response confuses me. What are you plugging into what in order to 
reach this conclusion?

You buy the mother and daughter cards (modules) as a unit. You specify what 
you want. For instance TDM22B is two FXO and two FXS. Go back to 
<http://www.digium.com/index.php?menu=wildcard_tdm400p2>, and look at the 
standard and custom configurations.

If you have two lines, I recommend a 22B since that will give you both 
lines and also the ability to plug in two cordless and corded phones, 
creating two hard wired extensions. Then you can transfer calls between 
them :) You could save a bit of money by buying a TDM12B - 1-port FXS & 
2-port FXO bundle but you'd wind up buying the second FXS sooner or later, 
and have to pay shipping to France twice.

I wonder if there is a local source for these in the EU. I'm not sure, but 
Digium could tell you.

You would plug your lines into the FXO ports, and your cordless (and 
corded) phones into the FXS ports. This is why you have to decide how many 
of each port you want.

My pleasure. At one time, we all were where you are now, so we're happy to 
bring you up to speed, especially if you ask good pointed questions, as you 
did.
