Somebody correct me if I am wrong, but I believe you can build a 
direct connect modem without going thru FCC certification; however
you must use an FCC certified DAA to do so.  Off hand, I believe 
Cermetec and Novation build FCC certified DAA's, there are probably 
other manufacutrers also.  Anyway, the DAA's are EXPENSIVE in single 
unit purchases, they aren't even cheap in 100,000 unit pricing.  
It may be cheaper and less headache to buy a modem than build your
own.  Good Luck!
