we are getting a T1 line and would like to know the commands that needs to be entered on the new cisco 2801 router. Router didnt come with a serial interface, so i purchased a WIC card to add to slot1. This is a point to point connection for internet from our router to the ISP router. assuming the ip address of ISP router is 220.127.116.11, what are the commands that i need to add to the serial interface.
The ISP mentioned couple of things:
Line is B8ZS
Frame is ESF
The CSU DSU function will need to be handled by the WIC as well.
After the Serial Interface is set to point to the ISP router, how can the fast ethernet interface talk to the serial interface. For example if i connect a cisco switch to the fastethernet port of router, how can users connect to the internet using fa0/0 through the serial interface.
