How to ISDN toward ISP?Pls

[imran_mcse]

I have Cisco 2522 Router. It has bri port(not mentioned S/t or U type), firstly i am confused about this that what interface type it has.

I am from Pakistan,in Pakistan external NT1 is used for connectivity(S/T interface).I want to connect my this router to ISP so that my network clients share internet via this using NAT feature.The ISP access no. is 13111333 so pls let me know the command and steps to accomplish this task. Pls provide me help.

The c2522 is without the builtin NT1, that makes it a S/T interface.

In order to connect to the ISP & configure NAT across the 2522, please refer to:
