1 edit | The Up Rate only being 1920 kbps/1.9 Mbps is a little concerning
Might be worth contacting one of the Tier 2 guys & have them run a couple of tests. From your Max Down rate being 60 Mbps, it can be assumed you are fairly close Loop Length wise to the VRAD, and therefore your up rate should be more than able to sync at the full 2048 kbps/2.0 Mbps |

Your stats look good. Your Max rate indicates as ILpt4u stated, that you are close to your local VRAD.
The normal profile for your indicated distance would be: 25216 kbps down and 2048 kbps up
Since your up profile is showing 1920 kbps there is an indication that there is a possible source of inteference in your upstream band of the VDSL signal.
Your Attenuation is showing at 17.1 dB, I would expect it to be above 20-21 based on your other stats. Again this may indicate a source of interference in your upstream.

Lubbock, TX | I would think the lower the attenuation, the better. |

His attenuation should be closer to 10-12 or so according to his other stats, so at 17.1 db, there is some undo interference on his line.

Just an FYI, That up/down is not my thorughput of my service. I just copied the info from my U-Verse statistics page on the \mdc page . My current service is 6016/768. I am just concerned about my attenuation for the most part. I do have a sort of digital tileing on my phone while the other person is talking which I think might be caused by the attenuation on my line, but I want to make sure before I start a service ticket with customer service. |

I contacted uversecare@att.com with this message:
I am getting a recurrable digital - tiling effect on my phone while the other person is talking. This happens during every phone call at least once during the call, the longer the call it will happen at least another time. One concern is that when Uverse was installed the tech said the outside line installer had to come to redo the line since there was noticeable noise interference on his meter. This was never done. I feel this is where my above problem is coming from. Please reply back. Thanks.
I hope to get a reply soon. |

West Simsbury, CT | Just out of curiosity... when you say tiling, what exactly do you mean.
I've noticed on some calls we will get an occasional beep like as if somebody pressed a number key. It's very loud and annoying... |

West Simsbury, CT | No, nobody pressed a number. It happens on both ends (we hear it sometimes, they hear it sometimes).
What is DTMF detection? |

Digital-tiling is that sound of like a repetitive rolling of the person's voice on one word, its annoying. If you remember the late 80's tv commercial digitally-animated character "max headroom" when he talked they would intentionally roll his words. Thats what the other person on the line sounds like.
FYI: I got a response from uverse care they are saying there is a bridge-tap on the line when they did the drop. They said that needs to be removed which they think it is causing this issue. |

West Simsbury, CT | Yeah a bridge tap could very well do that
And that is definitely not what is happening to us. I'll have to look into my stuff more. |

I found this tool to check my vdsl modem for interefernce.

| Well, did you reply and tell him how close you are to the VRAD? If so you should have gotten an email explaining what that interference in red at the top looked like AM radio stations interfering at those tones 720-1518 Khz.

I just sent a response to uversecare@att.com and will see what they say tomorrow. Also, on Saturday they sent a premise technician instead of a line tech as they promised they would. He said he would put in a ticket for a bridge-tap removal. Lets hope it happens Monday as the premise tech advised. |

| No I meant send a comment at Dohrenburg and Robert there will find what the interference is caused by. I had interference on 3 frequencies that corresponded to 760 WJR
AM and 800 CKLW AM here in metro Detroit w/o any problems caused by this.

I just sent a comment to dohrenburg with the link to my line analysis. The tech just came today to I assume remove the bridge tap. I am still getting interference on my line. I am hoping this fixed the phone issue though. We shall see. Here is the new test link.

I just copied this from my statistics /mdc page for my modem. My attentuation went up for some reason. If they fixed my line and removed the brigde-tap wouldn't it go down instead of up?

I performed another test with dohrenburg and it now says my line is using the pair bonded profile instead of the default vdsl profile. I know pair bonded is better, but I am getting less rx power gain. I used to have 25.0 rx gain now I have 6.0 rx gain plus 18.0 dbm of attenuation. I contacted uverse care and they said that the bridge-tap might be in the house. Now they will be charging me for this...?

I isolated the my uverse system without having the phone line connected, just ethernet, digital tv,and retrained the modem. I also did yet another analysis test from dohrenburg. Here is the link: »adslm.dohrenburg.net/tools/db-li···ink=1025
There is not much of a difference there is still inteference and 18.0 dbm of attenuation, so I believe that it is either the install itself (coax) or the line from the pole. The Uverse installer said he saw interference and that the drop needed to be redone. Lets hope for the best and see if there is a resolution. |
