[App_rpt-users] Radio connection with TDM400P

Good evening all, I am just starting out with all this Asterisk stuff and during my research I had a question that I couldn't find an answer to. Instead of finding and modifying a USB FOB or buying a URI, can I use a TDM400P card in the computer with FXS boards installed? Is there anything I should know about hook up and computer config. before hand? Schematics, drawings, or pictures are always a big help. Any info would be greatly appreciated! Thanks Wade KC0LMT
