I suppose it's also possible that your modem/router's system time is slightly out of sync with the PC's system time?
Just checked this - yes there is a slight difference, but only 2 seconds.
I can 99.99% guarantee that it is the DLM that has caused the resyncs. Ive had DLM changes every day and you can see that since they fixed whatever they did last Wed, the DLM has been slowly returning my line to normal settings a bit at a time each day. Since last Wed Ive had no other CRC errors aside from the normal odd one or two.
Its apparent that I only get this very high burst of CRCs when the DLM has caused the resync
PPP sessions can hang on even when the connection resyncs. ../snip ../
the connection can resync before a new PPP session is initiated (sometimes it isn't even refreshed following a resync).
hmm.. yes thats a possibility, I wonder if thats something to do with the cause of the CRCs?
Although from what I can see in the router logs, everything seems to be happening as it should.
Ive merged XDSL, Internet & PPPoE together as my router shows them separate, but it looks ok time wise and everything seems to have happened correctly. The PPP session terminated before resync and a new PPP session initiated after resync complete with a new gateway change which was previously 195.166.128.230

I suppose the question is, when did that CRC burst occur?
Because HG612 stats will have obtained them at 09:48, that means it has to have happened after 09:47:05 and I think we can safely assume that it wasnt a high burst of errors which caused the Loss of sync... so it would be after 09:47:32
