By Wednesday evening the crackling had ceased and the buzzing was very low. The fluctuations in the signal noise ratio on the broadband had also stopped. It was the same on Thursday morning when two underground engineers turned up, one of them had called on Wednesday to view the job. I told him all I knew about the previous visits as he hadn't all the information about the job. They were testing on top of No.2 pole on the far side of the rail crossing. Next they were digging close to the pole.
Some time later they called and said they had found and repaired a wet joint and asked how the phone line was now. As it had been quiet there was no obvious noise but I did detect the same buzzing noise but it was very low. Before they called on me I had been running Dslstats and didn't see any improvement that I hoped I would see on the QLN graph so I had doubts about the fix. With the low noise they were happy the fault had been fixed and we left it at that.
Some twenty minutes later I had an incoming call which triggered a lot of loud crackling, as bad as I had heard before. I went over the rail crossing hoping to see the engineers and fortunately they were still there. With phone in hand they heard it too. Testing again they couldn't be pick up a dial tone at that time which was good. Further testing revealed an intermittent fault some 10mtrs from the joint they had repaired. That was all they could do that day and said they would be back on Friday morning. Nobody came today so I will see what happens next.
Today the line has recovered a bit with less crackling but the broadband is syncing at its lowest level now. I have 18db TSRN on the D/s and 12db TSRN on the U/s The QLN is not as bad as the post but still looks poor.
