Clearly whatever the issue, the router should detect the condition and re-establish...

Chances are, it's running too hot. However, wifi still would not work, even after trying the diagnostic again. Since I have no possibility to verify the VDSL config, this is what i prepared. Proceed with Layer 1 troubleshooting in this case.Check the operating mode, trained mode, and TC mode. http://www.cisco.com/c/en/us/support/docs/asynchronous-transfer-mode-atm/permanent-virtual-circuits-pvc-switched-virtual-circuits-svc/10434-crc-tshooting.html

What Are Crc Errors

maybe just turn on debugging for ATM errors. For example, when you use a PA-A3, you can gather per-VC CRC statistics by first using the show atm pvc vpi/vci command to display the VCs. Actually CRC failures do occur at L2 on ATM cards and are counted in the interface stats. If there is no policing and this is just a best effort service, then CRC's are a fact of life.

I've been unable to match these CRC errors > to the counters for my interfaces. Troubleshooting Steps To determine the reason for the problems you are experiencing, follow the troubleshooting steps listed below: Determine if the CRC counter is incrementing or whether it is a historical If you change the operating mode between ADSL and VDSL, you might not need to reboot the router in order to activate the corresponding Ethernet or ATM interfaces.Check the noise margin Cisco 887 Vdsl Configuration Example and it is not doing so.
