And you have the right forum (DSL) to see what's been written before. For me I tend to ignore all those numbers and look at whether it works or not.

Do you know what is making all the spikes in the graphs? Is is a bad cable, corrosion in the lines, a ground fault, etc....... I cant find anything on google that explains what the graphs indicate is going on in the pairs.

That's what the service folk look at.

I understand that is what service folks look at, but i am curious what it all means. I dont understand why its such a big secret as to what the graphs actually represent. Are they showing noise on the line due to a bad cable, or interference or is there a weak spot in the pair coming to the house. I just want to know what they meant. I know i cant do anything about it.

You take the courses on the subject or research it with google. I don't think there is a one paragraph answer.

But those are reported by the dsl modem itself in that FAQ.
Your using a specialized meter and not even giving us the model so you need to go look up the manual online and read it.
