SoxFan,

I think there's some subtle evidence that you may have a bridge tap on your line.  For your distance, the max rate seems to low and the upstream power level seems too high.  For 1900 feet, I would expect a 42 - 45 Mbps max rate.  Yours is only 37 Mbps.

Call tech support, have them send a premises tech, and have him check your line.  He may need to call the linesmen's group (I&R) to come and find the bridge tap.  If you do have a tap, your bitloading graph implies that it's very far away from your house, up near the start of the line.  If you have one and it gets removed, the max rate should come up by 5-6 Mbps, and then your 32/5 profile will run properly.

If they can't find a bridge tap and can't condition the line any further to improve the max rate, then you will have to have the line moved to the 25/2 profile to prevent the errors that are occurring.

Thanks Joe I will give them a call today.  What should I tell tech when I call them? Just request a tech to come out and test the line? Will ATT go for that?

You'd want to tell them that you think that there may be a bridge tap on the line.

Or, you can skip the whole "script reading phone people" and email AT&T's uVerse Tier-2 Technician Team at uversecare@att.com.  Just give them your uVerse Account Number, a good phone number to be called at, and a good time to be called at as well.  Or you can just send them an email with your uVerse Account Number and tell them in the email what we told you.

I called up uverse. They said that the bridge tap as been removed from my line. However there is alot of "noise" on the line.

They are sending a line tech out tomorrow to determine the problem.

Please tell me how mine looks.....

Thanks!

We will have to wait for your images to be approved but when they are we'll be sure to look at them.

flhthemi, I'm seeing the classic bridge-tap sinusoidal wave, But unless you're experiencing issues, I don't know that I'd worry about it.  You're getting 32/5 and have some room to spare.

[trparky]

I'd still say to get that bridge tap removed, any bridge tap (don't care if it's not causing issues now) should be removed for it can cause problems later on down the road.

There looks to be a small bridge tap there.  However, you're close enough and on a good enough line that you have the highest available profile and it looks to be working correctly.

Unless you're getting pixelation or freezing you probably don't need to worry about it.

Thanks for the reading! I do get a little freezing and some pixelation on occasiion. I'm guessing a bridge tap looks like a splitter? If so there are two on the side of my house that were put there at inital installation.

No, a bridge tap is a length of wire that is connected to your pair somewhere in the middle of your line, and then goes to nowhere.  Usually this happens when a previous resident in another house had been assigned your pair sometime in the past.

Bridge taps will interfere with the U-Verse VDSL signal.

Well it's not something I can take care of. Think I should request service?

[trparky]

Yeah, I would if I were you.  Tier-2 Contact info is below...

Please see the following thread...

Or, simply email David and Matt at uversecare@att.com. Simply send an email explaining the situation as best as possible with your uVerse account number, a good phone number to be called at, and a good time to be called at as well. If you have any past trouble tickets that you are aware of, include them as well; any extra information is going to make David and Matt's job easier.
