Using the right pieces(ATA+Asterisk, or Asterisk with analog card and two fxs modules) I successfully create a fake pstn and connect two 56k modems(Windows to Linux or vice-versa) to emulate the old good ancient internet of the 56k era. Using the right hardware is also possible to emulate a isdn circuit(isdn gateway + asterisk or asterisk + isdn bri card). I have also the idea to emulate an ADSL, only for hobby/testing, nothing professional or serious. The question is: using an hardware like the VC-231G
is possible to use two of them(one master, one slave) and connect two adsl modem in a p2p way(Linux pppd + Linux pppd or Linux pppd to Windows), maybe using asterisk to simulate the pstn?
