I have posted about this before but,I ask as perhaps OR have enhanced equipment to trace Shine
My case is a high burst of CRC with a fall of SMRM to zero or below. On most days this results in a resync. This happens daily at 0921 or as near as DSL stats will report.
I’m aware that @blacksheep often talks about the cone of acceptance. I fully appreciate this approach, especially considering the vast vagaries of DSL.
I suppose the question actual boils down to, is a daily resync within that cone of acceptance, and if not, is technology able to find the source. It’s certainly not on my premise.
All that said if I didn’t have line monitoring I likely wouldn’t know, and my neighbours, who likely suffer the same don’t either ! Only occasionally the line resyncs while noise present with a bad connection, requiring a manual resync.
