As I can see from Your first post, You are using BRI in
point-to-multipoint mode. On BRI lines there is nothing like CRC/CRC4
and that is the reason, why the config is not loading any more.

On a PTMP line there may be some CRC-errors from time to time, when the
provider shuts down the line, which is normal in some countries. But
this has nothing to do with Your initial problem.

Unfortunately I don't know a solution for Your problem. It may be a
hardware issue.

HTH,
