I called the tech and told him what was mentioned above and he said he understood what you're saying but the root cause of my issue was due to the fact that I was moved to a pair that is not supported for U-Verse. (He said there were 3 pairs and 1 was available for me and it was 'unconditioned'.) So I'm basically getting my U-verse service on only one pair and that's why I'm seeing these intermittent issues.

He said in about 2 months he'd be able to have Engineering come back and install two pairs to work from instead of the one that I have now. (And this should give me 25/2 instead of the 19 I have now.) I guess this was the 'enhancement' he was talking about in my previous post.
