Since you have gotten plenty of responses on this I thought I'd throw 
out another option. If you just want to play with how a PRI connection 
behaves without all the hardware investment, you can emulate a PRI over 
TDMOE. I did it a while back just to see how calls were passed back and 
forth and how result codes were set. Everything is configured the same 
in asterisk, you just use a dynamic span instead of a physical one. You 
will still need one side to have a timing source (I did get mine to work 
with just ztdummy).
