Seems to have cleared upnow that system is on site and connected to Telco. Must have been issue with PRI test set I was using. I had never had an issue using it the same way before.

I am getting this same error repeatedly on a NV6355 with the fxs module. This is the second unit I have seen this on. On the first one, which I RMA'd, the line would occasionally not pull dial tone. When I replaced the FXS card it made no difference. Now that I am getting this again on a brand new box and card, I am kind of suspicious. I am not using a PRI. This problem persisted from an upgrade from R10.6 to R10.9. Any ideas?

This error is usually caused by an unstable clock source.  If that has been thoroughly investigated and the problem continues I would recommend opening a ticket with ADTRAN support.

Thanks,
