The Cisco 2503 has an S/T ISDN Interface NOT a U interface. Meaning you need an NT-1 Adapter to connect to the ISDN line from the telco.

Subject: ISDN BRI dialout help

Hello,
 
I am trying to configure ISDN BRI for dialout using 2503 but could not connect to remote access server of the ISP. I have taken a ISDN dialup account from ISP and it has given me "userid", passwd and dialup number. I tried these through normal dialup (windows dun) and it connects succesfully. Now I have following configuration for my 2503 router but this could not connect. Please advise if I am missing something as I am new to ISDN and doing it for the first time
