The interfaces should show up regardless of whether you configure them.
When you do a sh run or a sh interfaces you should see all available interfaces in the router whether enabled/disabled or configured/unconfigured. I would suggest you to reseat the WIC cards and make sure they are detected.
Find the below config may help...
controller t1 0/0
framing esf (should match the other side mostly esf)
line code b8zs ( do )
clock source independent
ds0-group 1 timeslots 1 - 10 type fx0-ground-start
Here most of the config depends on the type of device you are connecting to. If connecting to Telco/ISP they may give you some details like framing, line coding etc. You can also configure the Pri-group if you want to use CAS.
Please rate if this helped you...
