We are going to configurate an E1 to connect to internet using a router 2811 using an Interface fastethernet(embebed in the router), I was wondering if you could provide me some recomendations/tips/theory or guides to underestand all the proccess, I know that ISP also types some commands. there is(are) documents where can explain the commands typed(in both sides. ISP and client). Any kind of info. about this configuration will be very appreciated.
Thank a lot.
