Sounds like a possible carrier frame-relay switch mapping mishap. Maybe they added/changed some DLCIs to their switches and mucked up your PVC/DLCI mappings. Do you see CDP neighbor info over this DLCI (sub-interface) if CDP is enabled? That would indicate broadcast traffic is getting across the PVC end to end. Another idea would to clear the counters and do a ping test and see if other site PVC stats saw a increase in input packets relative to amount of ping traffic.
Get on the horn with the carrier and have them verify the PVC mapping end to end, and verify the DLCI #s they have in their switches are the ones you are using still. Stay on the phone when they do this. Also, they may pass it off to some other intermediate carrier who has it messed up. The carrier can also monitor the PVC/DLCI traffic while you do some ping, data tests -- see if they see traffic being sent and received. Do a large 1500 byte ping for like a count of 200 just to get some data flowing while they look at it. If you have newer IOS, (12.03T and higher) you can try the Frame Relay End to End Keepalive (FREEK) feature too. This will force the DLCI/pvc down and sub-interface down if the keepalive packets aren't seen at other site. This probably isn't going to get you much but might show the smallish FREEK packet is getting across. Just another test similar to CDP packet test.
