I have two 1720 routers with WIC1DSUT1 WIC cards that we are using for a P2P T1 connection. I have attached the config from one of the routers. The config is the same on the router except for the IP and the clock source internal command on the other router. Currently the serial interface will come up for about 30 seconds and then the line protocol will drop. I believe that I set the clocking on the routers correctly, but I may be wrong. Is there anything else that I need to setup to get this T1 to work correctly?
Thank you for your help.
