Changed to T1 from ATT, tired of local (lack of) service.

have 2621 router running 12.3 and the old config is as follows

interface FastEthernet0/0 description OUTSIDE INTERFACE TO THE INTERNET ip address ip access-group 101 in no ip redirects no ip unreachables no ip proxy-arp ip nat outside speed auto full-duplex no cdp enable ! interface Serial0/0 ip address ip access-group 101 in ip access-group 102 out ip nat outside no ip mroute-cache ! interface FastEthernet0/1 description INSIDE INTERFACE TO PRIVATE NETWORK ip address ip nat inside duplex auto speed auto ! ip nat inside source list 1 interface FastEthernet0/0 overload no ip http server no ip http secure-server ip classless ip route ! !

The info I got from ATT is Customer Serial IP Address: AT&T Router IP Address: Subnet Mask:

So my question is, which is which? is the 122 address the IP of my Serial line and 121 the other end at ATT?

Customer side is you, your gateway (their side) is 121. That is my interpretation.

AT&T Router IP Address:

should clarify it. AT&T router means router under AT&T authority. So .122 is your side. You're AT&T's customer.
