Frame-relay sub-interfaces will not come UP

There is a Headquarters router , a Branch1 router, and a Branch2 router connected to a 1760 Frame-Relay switch. Clocking is configured on the Frame-Relay switch, however, I cannot get the serial sub-interfaces to come UP on any router. All configs are shown below. Any assistance would be greatly appreciated.

thanks,

Ron

Frame-relay sub-interfaces will not come UP

This problem has been resolved. I had mismatched LMI types.

Thanks,
