You're probably correct assuming the TDM card has been recognized. 
However, the majority of users on this list are not TrixBox or FreePBX 
users and it would appear at least part of your problem might be related 
to the various scripts and macros embedded in those implementations. 
Therefor, you might pose your questions to the lists supporting those 
implementations.

I (for one) became frustrated with the lack of documentation for FreePBX 
and gave messing with it. It was taking longer to figure out what was 
supposed to be happening then what the benefits of the gui interface was 
providing.
