Reviews: The illiterate of the 21st century will not be those who cannot read and write, but those who cannot learn, unlearn, and relearn...But if the above is the case then I don't see it has being of much use if you want to learn about configuring ISDN...For that you need something like an Adtran Atlas 500 that can simulate an ISDN cloud which you connect to the appropriate interface on your lab router...
