Serial interface says line down, protocol down

i have a serial interface that says down, down. I have looked at both routers and the encapsulation is correct. The one router says s1 is up, up and the only thing configured on it is the ip. on the other router the s1 interface is down, down. I was always led to believe this is a physical problem with the cable or the interface itself but I was told to check my config. it is not administratively down either. Any thoughts would be great!

THX!
