| Is this a new profile? While browsing this site »adslm.dohrenburg.net/vdslm/vdslm.php
I found what appears to be a new uverse 36200 profile
»adslm.dohrenburg.net/tools/db-li···ink=1125
my question how close do i have to be to get that profile?

| It's a goofy one 36200, 32M profile is correct one. Depends on distance from VRAD, signal/noise rates, max sync, wire guage and condition, so no hard and fast distance rule.

| I just talked to the owner of the site he said that the post is legit and to 'notice' this numbers.
quote:
Total bits in all upstream bands = 0 + 1621 = 1621
Total bits in all downstream bands = 1692 + 4526 + 4244 = 10462
he also said that the poster is located in richardson tx where all the uverse tests are.
what makes u think it is bogus? |
|
| Do you see the word 'bogus' in my first post? Just said it was goofy and does not line up w/32200 like us regular folks are getting.

This is my profile. I'm in Richardson TX. All the copper lines in the city were replaced with fiber starting in 1995. We don't have normal VRAD boxes but small boxes in every alley with copper to each house (40-400'). We are not a test area - Austin TX is. In fact, it was over a year after AT&T began offering UVerse in the city (which was several years after the 1st offering elsewhere) before it became available in my neighborhood (July). I've had this profile since Dec 1st.
Don't ask me why it is different - my max down rate has always been in the 73000-75000 kbps range until 12/1. Now it is 64000.
DSL Line (Wire Pair): RJ-11
Protocol: G.993.2
Downstream Rate: 36200 kbps
Upstream Rate: 5040 kbps
Channel: Interleaved
Current Noise Margin: 28.0 dB (Downstream) Not Available
Current Attenuation: 8.0 dB (Downstream) Not Available
Current Output Power: 11.0 dB (Downstream) -8.2 db (Upstream) |

| Practically everybody's max sync goes down when G.993.2, VDSL2, software is downloaded into the RG. Mine went from 62-63M to 60M when it downloaded.

so you are less then 400'
I hope at&t brings uverse to pharr tx. |

Chris Also be aware of it the VDSL2 not only lowers everyone sync rate it also caps or reports the max sync at 64 megs as my Sync rate went from 91megs under VDSL1 to 64 megs under VDSL2. I highly doubt VDSL2 reduces the max sync by that much as it would really not be an upgrade but a downgrade in technology so it is very possible that new software is not reporting the max rate correctly and people max rate might have really increased and not decreased under Vdsl2.
VDSL2 deteriorates quickly from a theoretical maximum of 250 Mbit/s at 'source' to 100 Mbit/s at 1640 ft and 50 Mbit/s at 3280 ft. And VDSL deteriorates quickly from a theoretical maximum of 100 Mbit/s at 'source' to 64 Mbit/s at 1640 ft and 25 Mbit/s at 3280 ft
So I have a felling the software is reporting the wrong max speed or ATT has not enabled VDSL2 in the Vrads or ATT coper pairs are just super bad compared to coper pairs in most other countries as some countries around the world are seeing VDSL2 connection at 50/50 and Qwest is able to delivery 40/20 @ 2k from Vrad in ST Paul and Denver for the last 6 months. |

| My guess would be that AT&T is capping the top rate at 64 meg because before the VDSL2 upgrade my max rate varied between 67 - 68 meg. Since the upgrade, it has been at exactly 64 meg. When you think about it, 64 meg is currently more than sufficient when the top profile will be 32 meg. More bandwidth would simply be wasted at this point until there is a need for more bandwidth based on higher profiles than 32 meg. |

More bandwidth would simply be wasted at this point until there is a need for more bandwidth based on higher profiles than 32 meg. I am not disputing the fact that ATT might be capping the max sync rate at 64 megs, but based on pure theoretical maximum for VDSL vs VDSL2 which I know are unrealistic as chances are most people don't have new pristine coper pairs which are used for those tests the max sync rate should have increased for everyone which is what leads me to believe the VRAD are still using VDSL possible and have not been switched over to VDSL2 because otherwise we should be seeing more people with max sync rate of 64 megs and not with reduced max sync rates. Or the routers are not reporting the correct max sync rate.
If you look at my line I was loosing 9% of the total bandwidth from the VRAD to my RG as VDSL 993.1 had a max sync rate of 100 megs at the VRAD and VDSL2 is supposed to have 250 meg sync rate at the Vrad according to 993.2 specs. I have a felling ATT has not switched over the VRAD or increased the max rate from 100megs which could be why people are seeing their max drop instead of going up. And once ATT switches the VRAD over to 250 meg sync rate at the Vrad we should see many people with well over 100 meg max sync rates unless ATT is limiting the max bandwidth rates in which case pretty much everyone under 1500 FT should see 64 meg max sync rate which currently is not the case. |

Mauldin, SC | FWIW, I do know for a fact that no work was done in my VRAD prior to or since the upgrade we received on the RG. |

Still don't believe they've turned VDSL2 on in the VRAD either. All they've done is download the VDSL2 software into the RGs and fixed some other bugs. In Fall 08, it was mistakenly turned on and my max sync went from 64-65M to 114M for 6 weeks until a power outage.

Well, at this point we can all simply speculate based on our best guesses of what we see. Since we are not in the inner circle at AT&T, we will just have to wait and see how things unfold. If our current bandwidth is sufficient to support the new 32 meg profile, we should be set to go for now. |

said by Tel:FWIW, I do know for a fact that no work was done in my VRAD prior to or since the upgrade we received on the RG. I dont think the VRAD need any psychical work to be done, I think it is a simple upgrade that can be done remotely via software which would explain why mibrnsurg sync went over 100M for 6 weeks till a power outage reset the VRAD back to default setting which could be VDSL1. |
