Actually, Frame Relay switches don't forward the loop messages received on local port to the remote port. You can only loop between each end router and it's local Frame Relay switch. So, unless this is a cross-over simulation, you won't be able to achieve end-to-end loop. So, you can do loopback tests between each end router and it's Frame Switch. As long as those tests show fine - and your configuration is correct :-) - and you still have issues it might simply be the telco problem. But most often than not, you gotta prove it to them by running these tests.
