| Fed up with my service Have had Uverse HSI since August 2011. Originally got it with TV in order to get the free install, after a month of subpar TV service with screen freezing issues and loss of TV signal on a few occasions ( STB was fed from a brand new Cat5 ethernet run), and annoying billing issues we cancelled the TV and stuck with the internet.
Since getting Uverse the RG would lose sync 1-2 times a month, then just about a month ago it started losing it about once a week at least, usually in the evening....this is just like our old DSL that we replaced with Uverse.
Two techs in the past two weeks have swapped us to different wire pairs and all to no avail - so far. All of my neighbors except the one right next to me (who is served out of the exact same pedestal as me) have had no issues at all with their service over the years. The technician that was here last showed me what all my neighbors RG's were syncing at and every one of them was syncing at over 40 megs (even the one that had issues before), and capable of the 32/5 profile if not already on it, we're only syncing at 34 megs and can only get 25/2 profile/18/1.5 internet. He was supposed to put in a request to get a lineman out to find me a good pair and get back to me right away, never heard a word from him after the last visit though, so I'm on my own again.
after 4 days our RG lost the connection again, in the evening as usual... All of the neighbors on my block have looplengths of 2,000-2,200 feet, we're at 2,000 feet, so the distance isn't terribly long and doesn't explain why were having issues and they're not (in fact alot of them are on the exact same cable feed as us). Inside wiring to the RG is very minimal, just an 8 foot run of CAT5 straight from the telco side of the NID, to the RG, the DSL is on it's own loop separate from our POTS.
I posted in the direct forum a couple days ago and am awaiting a response. So far I'm just getting started but I already feel like I'm running out of options as far as getting someone to actually find the issue and correct it.
I posted my UV Realtime stats above, tell me what you think. One thing I don't like is the low Noise Margin...and I'm not quite sure about the bitloading graph either. |

| I don't think you are really at 2k feet but I think that pair you are on now has a bridge tap based on the upper side of the chart going up down up down on the bits.
If the get the bridge tap off I bet you get 40 meg sync.
Also depending how good you are with this kind of stuff go check the wires in the AT&T box and make sure the one going into your house is not really old and cracked up looking.
If so replace it, or see if you can connect RG straight to box using a clean short pair you connect yourself to rule out internal wires. |

According to the records from the VRAD itself my looplength is 2,000 feet. my neighbors range anywhere from 2,000-2,200 feet. If there were a bridge tap on the line then that means that these techs are seriously not doing there job and/or are too lazy to check every pedestal (which nobody has yet).
All of the wiring on my side is brand new, RG already has a short piece of Cat5 running from the NID to the RG. |

| Hey when I had issues when I first got it they all told me no bridge tap also and showed me the test that even said none detected, but it seems another more advanced test that I had to have someone higher up did because when they came back (like the 5th time) they ended up calling a dude that tore up the ped and dug down about 8 feet deep to remove a bridge tap they found and after that my sync rate jumped and everything else sits nice at 0 except corrected blocks is about 12 a day and my bit map looks cleaner and I am over 1500 feet away also.
My house was built in 86 but I had them run new wire from ped to the other side of the house as RG is on wall behind it and used a 3ft cat5 cable to link into the RG. All has been well (minus crappy pings but thats normal for interleave and me being in FL with only one major AT&T pipe out of the state...) |

Back when you posted a tech switched your service pair and the max rate and noise margin went down... was cause enough for alarm. Repairs are supposed to make things better. |

And it made no sense at all, since that first switch it's been switched again and the noise margin went down even lower as you can see. the max rate went up by 1 meg though. Something is not right, and someone isn't doing their job to the extent that is required here. |

I do know that the last two techs didn't really run any diagnostics. I have another visit scheduled for tomorrow morning, and I'm still waiting for tier 2 in the direct forum to get back to me. Hopefully someone can fix me up here, fortunately I'm just getting started with the whole pester-AT&T-to-fix-my-problem thing. My neighbor across the yard is actually a project manager at AT&T, naturally he gets great Uverse service. (he's one of the ones fed from the same cable feeder as us too)
Our home was built in 1990 so it's not much newer then yours. All of the wiring seems to still be in great condition though, and they usually are out doing something every couple years as far as upkeep in the neighborhood. Ironically when they were out replacing connectors and checking lines back in December is when our service really took a dump. |

Had another guy out today, he cleared the bridge tap from the line (it was only a short ways down the line actually)
Above are the new UV realtime stats, and yay it finally recommends me to the 32/5 profile!....I guess that's my next project, will sit on 25/2 a little longer to make sure it's reliable though. |

| Just a thought as an old repair foreman for AT&T/SBC/SWB. To do a really good job locating bridge tap, the best tool is a TDR, a time domain reflectometer. It will give the distance to a bridge tap. It can also be located if the tech has a really good set of outside plant records. |

Max rate still looks a little low for 1600 feet. I am at 2100 feet with about the same max rate.
We always used an oscilloscope to find defects in both coax and twisted pair. We didn't have tdr's back then. Distance was calculated at roughly 1.3 nanosec per foot. we always put a 50 or 100 foot coil on coax or tp on the front to get the signal away from the sync. |

That's exactly what this last guy used, and he got the job done in 45 minutes. the guy previous to him didn't bother using his, and the one before that used one but switched me to a different line instead of fixing it (which just made the issue worse). The ones that did use their TDR's both came up with the same results, about 20 or so feet of bridging about 100 feet up the line...which led us right to a 3-way pedestal in my yard, the bridge tap ended in a pedestal about 20 feet over from that one. He cut me out of the multi pair connector and connected me straight to my line in that first pedestal and that was that. |

I'm actually at 1,900-2,000 feet according to the VRAD's records. But I agree that it's still a hair on the low side, the next door neighbor is syncing at 44 megs, and two doors down is syncing at 46 megs and his loop is 200 feet longer then ours. |

Just as a guess, since your pair was switched a couple of times, I suspect that the tech doing the last switch didn't check for "left in drops" which are one form of bridge tap, but that is just a guess on my part, since I wasn't there.
One of my technicians was an absolute whiz with a TDR and could fix just about any cable pair with the info from his TDR. I tried to keep him supplied with the most current one and pass the old one down.
I don't know about regular repair guys and the number of TDR's, I had all needed because I had responsibility for T-1 lines. |

| Ha, told ya was a bridge tap 
Anyway, your line will NOT support 32/5 even though UVRT says it will.
This is because your line will not support 5Mb upload needed
You are best to stay on the 25 profile.
Your upload is probably in the 3.5-4 range. (not what you will get but max sync wise)
I know at 45 on the down it will be just shy of 4.9 on up and you are only 41 so no way it will support 5.
Going to the higher profile will bring you new issues because the line will be provisioned to high and upload will end up doing a lot of error correction.
You can confirm this buy calling and talking to level 2 or having a lvl2 tech check the actual line stats (not what the router shows).
Anyway it still kind of looks like another bridge tap may be on the line, did he recheck the line after the first one was removed?
I guess it's possible the wire running down the street is not the best but I know mine from the mid 80s is somewhat decent.
Anyway at least you got better so is right direction and no worse off |

| You may think it's fine but do YOU have access to what your upload sync is at?
The end user is not able to see this.
Just because you are on the profile and not noticing issues per say does not mean it's not struggling or having issues behind the scenes.
The simple fact is if it ain't over 5040 it can't sync at 5040 which is what the 32/5 profile requires to work correct.
This is why I said he should call level 2 support or have someone check it who has access. Its possible the upload sync is able to reach it but in most cases the line simply can't handle it and the user can't see upload to know it.
Same thing holds true for bonded pair people. You can have bonded pairs and show down of 50Mb but upload still be less than 4 (thus why inid installs are limited currently to lower speeds). It's all about distance and line quality. It varies from person to person but on average a users down needs to be around 45ish to have the up be able to fully support 32/5.
Same for you, call or have a level 2 check and tell you what your actual upload sync is. It ain't 5040 so its either higher (doubtful with that down) or lower, which means it technically shouldn't be on that profile. I also don't think level 1 support can see it and most that don't know any better will say it is fine.
In all, if your line is correct you should see 0 uncorrected blocks and at most a few hundred corrected blocks a day. (Unless a lightning storm is going on, in that case it will have some spikes which is normal)
I have down sync of 53841, my upload is 5548 and I have 0 uncorrected blocks and about 12-25 corrected blocks a day.
My line runs 32/5 fine because my upload supports it.
UVRT says 32/5 is recommended the second it sees the down is good enough but it has no way to see the upload to be 100%, its just a estimate and should only be taken as one.
To each his own but just trying to save people trouble and advise how things should "properly" be configured. |

This last tech ran a SELT test on the line and said everything checked out good as far as that goes. I'm sure there could be another thing wrong with the line, but it sure is alot better then it was before, I'm still not syncing up as fast as my neighbors though, I'm gonna go over the cat5 run to the modem though and make sure everything is very neat, those AT&T techs just don't leave the wires as neatly as I do hehehehe.
I'm pretty sure when he was testing the line after removing the bridge tap he showed it syncing at 6 megs up, either I'm crazy or it really was that high. I'm probably gonna contact tier 2 and see if they'll even give me that information to confirm what I saw...
My line goes through 4 pedestals before it actually reaches the drop to the house, and so far they've only made it up to two of them to check connections, so I'm sure there's something to be found in the other two up the way a little bit. If it acts up anymore then I'm sure I can get someone to look that far. |

GusHerb94,
I noticed a posting you have in AT&T Direct about 32/5 profile. It doesn't appear to have been viewed. Did you ever get a response for this? |

I sent an email to uversecare@att.com and got an almost instant response, I am now on the 32/5 profile! my max attainable down is running at 41 megs, and 6 megs up. Andy in tier2 said he didn't recommend moving me up based on my history, but was more then happy to let me try it and see if it works for me, so that's what I'm doing, and so far so good. |
