serial is up, line protocol is down (looped)

I have P2P T1 from A to B location. At the A location, I got "serial is up, line protocol is down(looped)". Both routers are set to ppp encapsulation. The clock source is set to line at A location and internal at B location.
Any ideas why I am getting this???

Most likely, the telco has the circuit looped. Call them and ask them to take it out of loopback.

Should I try "down-when-looped" command? Would it do anything????

No. The circuit will still not pass any traffic.

When I configured the routers, I put the "service-module t1 remote-loopback full" command on both routers. Do you guys think that the problem is related to this command or it is definitely a Telco problem.

Doubt it.

Have you contacted your telco?

I think that is a Telco issue  because I have another circuit set up the same way as the other one. It just works fine with the "service-module t1 remote-loopback full" command.
