What sort of environment is this in? If it's servers you have built  
and supplied to others, I can understand why it is such an issue.

I have a 3 FXS, 1 FXO card. On the one occasion I had to move the box,  
I left the line cord in the FXO. Because the other end is not RJ11  
here, that saved me making a mistake.

I hadn't actually thought of the adaptor in FXS port idea, but that  
would work too. When I wired the internal lines at my house, I  
terminated each with RJ11 to fit the card. I could have used BT plugs  
and adaptors, perhaps.

If you are in a country where RJ11 connectors are used on everything,  
it is much harder to resolve.
