My 1760 has a WIC1-T1 card in Slot 0 and the slot 0 "OK" light is lit. When the router boots it shows that it sees the T1 card. I would like to configure my T1. I received the following details from my ISP: * Removed IP's

IP Version: IPv4
Router Interface: edge1.mia1 -- t1-2/1/0:2:13 --
Switch Port:
WAN Network: 4.59.?.?/30
Level3 Side: 4.59.?.?
Customer Side: 4.59.?.?

Cust. LAN IPs: 4.59.?.?/27 

The problem is that it is not listed under interfaces. I am a noob with IOS, please let me know if you need more details. Thanks.

Apparently it IS listed, I just need help configuring it: – Joseph Jan 13 '11 at 0:56
Serial0/0 is administratively down, line protocol is down Hardware is PQUICC with Fractional T1 CSU/DSU – Joseph Jan 13 '11 at 0:56

conf t

ip default-gateway 4.59.?.?
ip route 4.59.?.?

int serial0/0
no shut
ip address 4.59.?.?

the first two 4.59.?.? should be replace with the "Level3 Side" IP and the last 4.59.?.? should be replaced with the "Customer Side" IP.

There may be some additional S0/0 configurations needed, especially encapsulation on a T1, but the above will get you closer than you are right now.

That is MUCH closer thanks. Here is the current status: – Joseph Jan 13 '11 at 2:45

Now, if i set my ip to one in the Cust. LAN IPs range, and set the gateway to the Customer Side: 4.59.?.? it will not route. Any ideas? – Joseph Jan 13 '11 at 2:47
