Since Saturday my phone line has been crackling like crazy and the VDSL keeps going off, I called my Phone provider who arranged for Openreach to come out this afternoon, the Engineer kindly called at around 1pm and said that he was just having some lunch and was about 10 miles away would be here at around 2pm, whilst he was on the line the crackling was still going on but he said he could not hear it at his end.

Anyway he turned up at 2pm as promised plugged in his phone and everything was ok, I plugged my phone back in and it was still fine, nearly 4 hours after his visit and the line still seems fine, he claims he had not done anything before he arrived, after he left I thought I would try rebooting my HG612 modem to see if the crackling returned, When I rebooted my HG612 modem this afternoon I got this message as a retrain reason: "6 ANSI Tone Power Change" in the HG612 Logs Stats viewer by Ronski does anyone know what this means?, would have Openreach done something at the exchange prior to their visit?

Below is my stats from the last 6 hours

Might need to ask broadcom for that one... It's defined in the bcm96358 chipset driver without any further explanation, and there doesn't seem to be much discussion of "ANSI Tone Power Change"  elsewhere.

Can't find references to "ANSI tones" in the context of DSL. Possibly it's an error on broadcom's part and it means an SIT tone - https://en.wikipedia.org/wiki/Special_information_tones - not an ANSI tone? Not sure that makes sense as SIT tones are low frequencies which wouldn't pass a VDSL filter.

edit: Maybe ANSI tone just means tone, as ADSL is an ANSI standard. In that case I guess it means power levels dropped on enough tones that maintaining sync was impossible.

According to this thread, the values should not be interpreted so literally:

Thanks for your replies, Normally when it resets I get Reason Code 1 which is a Remote Defect Indicator/DLM, this was the 1st time I saw this code which was just after Openreach had called. Guess it will have to remain a mystery along with why my line stopped crackling minutes before Openreach attended!

Thanks again!
