Help - Do these line stats look normal?


Help - Do these line stats look normal?

Hi All, 

I've been on u-verse for several years with the 25/2 profile and have been very happy with the service and stability but I'd like to get the 32/5 profile so I can get an internet package with the higher upstream speed and another HD stream.  After talking to neighbors on either side of me and looking at their linestats I think I should be within the distance for the 32/5 profile, but my line stats tell a different story.  I've read the readme for UVRT but still can't make heads or tails of the bitloading and other stats -- hoping that SomeJoe or anyone can help me analyze these...




Incase those images aren't approved yet, here's links as well:



I'm not seeing any sinewave drop out patterns but it feels like the bit loading drops off very steeply compared to others I've seen.  Also, the noise margin seems low for my estimated distance I think. 


The neighbor on the side closer to the VRAD has max rates in the mid 50's with much higher noise margins and neighbor on the further side has max rates in the mid 40's and higher noise margins. 


Additional info:

I live in a neighborhood that is only about 12 years old and was "wired for lightspeed" when built back in the SBC/SNET days. 


By the tool calculuations I'm on the edge of the 25/2 profile but my service quality has been very good -- never get retrains, uncorrected blocks are never more than 1 or 2 per day (often 0), corrected blocks are usually in the 10k - 15k/day (many of which are from voltage sags when the furnace or A/C kicks on and off), and I rarely have pixelization or TV freezing issues. I had the tech and I&R out twice right after the original install to get my uncorrected and corrected blocks down  -- went from 100k / day to where it is now. 


Does anything look suspicius in my stats?  Would it be worth contacting level 2 again and have I&R come out to take another look? 


Thanks All.


P.S. SomeJoe -- very nice work on UVRT this is a very cool tool.

It's true, the line can handle 32/5, but just barely. If they do switch you, be watchful for pixelation, freezing, or retrains/resets. If you start to get those symptoms, you will have to go back down to 25/2.

I do not have U-verse internet or phone, strictly TV only.  My understanding is the upload bandwith of 5kbs can be lowered below the 5 kbs spec.   If this is true, than hopefully this will provide the line more available bandwith.

Yes, upload can ride lower than 5K in your case, but the download is actually the concern, there is only barely enough room to carry 32Mbps down, regardless of how much of a reduction in upload might be acceptable.

In addition, the equipment is not meant to run with either the upload or download user bandwidth below the assigned profile rate, and doing that can cause other problems.

Re: Help - Do these line stats look normal?

I am thinking maybe better to leave well enough alone and not go for the 4 HD streams.  I mistook the "recommended profile" on UVRT as the preferred profile to use; not realizing the line would be maxed out.  I don't want to have problems in a few months due to weather conditions reducing the line's capacity and I have frozen pics. 


Will see what the tech as to say about reliability, etc.

Re: Help - Do these line stats look normal?

I decided not to get the 32/5 profile and cancelled the tech appointment.  One of the overriding reasons is I have had zero problems with the 25/2 profile.  Knowing I am beyond AT&T's distance recommendation and the higher profile would put my line at its limit, I don't want future problems for the few times I might need 4 HD streams.  Reliability of the service is number one for me. Fortunately I have OTA for the local channels and they should cover the occasional simultaneous sporting event broadcast where the 4HD profile would be of benefit.


Thanks for the suggestions and help.
