to really play around with ISDN, you need a BRI or a PRI (if you are at home, not that cheap). You need an ISDN Network to use your ISDN interfaces, to build one by your own will be difficult. -----Urspr|ngliche Nachricht----- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]Im Auftrag von Thomas Gesendet: Donnerstag, 7.

I wonder if it is possible to setup the simulation for ISDN with this 2 routers? What else do I need? I know it is not going to be the same as the serial interfaces (which I can use crossover cable), since ISDN involve the phone numbers.... Thanks in advance!
