Regarding DM3 and springware boards

Hi All, I am very new to dialogic boards. I have Intel's D41JCTLS board. I am not getting any pdf's or documents related to this. I went to Intel's site with this configuration. The documents related to this board is currently not available. I need to understand the board architecture, how it handles the call control and provides an interface to the call manager software. I also dont know the difference between DM3 and springware boards. I could not get the full form of DM. D - Dialogic. What is M?? I am sorry if I am asking very basic questions. Kindly help me by giving a few documents related to these board concepts. It would be great if I can get some free online books available on these basics. Thanks in advance. With Regards, Speakspeech
