I just purchased a refurbished Cisco 1721 router with a WIC-1DSU-T1-V2. I was able to connect to the console via serial and performed the initial setup for Ethernet0; however, I do not know where to begin to setup the WIC, and I don't want to pay for someone else to configure it if I can get the information here. My ISP gave me the following information (I am hiding the IP's for security reasons):
IP Address Allocation: aaa.aaa.aaa.aaa/28
WAN-Side: bbb.bbb.bbb.bbb/30
Network IP: ccc.ccc.ccc.ccc
Broadcast IP: ddd.ddd.ddd.ddd
Subnet mask: 255.255.255.240
Available IP addresses: eee.eee.eee.eee-eee
Gateway IP (Router Address): fff.fff.fff.fff
The dmarc will not be extended to my server room until the end of the week.
My question is, once I plug the dmarc into the WIC, will the router automatically pull the information from the ISP? Or will I need to manually configure the WIC? If so, I would appreciate quick setup steps.

Do you see the serial module when you perform a "show ver" or "sho run" command? If so, you need to know whether to configure for frame-relay or full T1 setup. You also need to find out the type of encapsulation the ISP is using on their end. I do not think the serial interface (WIC card)can be setup to get ip information from the ISP DHCP server like residential router can. Please provide more info so we can help further. Thanks.

Hi David,
Thank you for your response. The router shows the following information when I perform the "show ver" command:

The configuration is for a full 1.5 MB T1. I'm not sure of the encapsulation, but I believe it is HDLC. I am waiting for confirmation from my ISP.

Hi Thomas,
You must know the details such as below and configure under "interface config mode":
-clock source (depends on your telco)
-framing and line coding (depends on your telco)
-timeslots (depends on your access bandwidth)
-and of course your IP address details
