Unclear: What speed can I really expect from U-Verse

I'm sorry; I suspect this has been asked/answered before but I can't find it...

I'm a Comcast cable subscriber (Internet & TV) considering a switch to U-Verse. I consistently get 28/5 from Comcast.
If I'm on my roof I can see the VRAD, 2.5 streets over; to walk to it takes 3-4 minutes.
When U-Verse first became available for my address, the internet portion offering was "up to 3Mbps" -- An unacceptable step down from my existing cable. I looked again a few months ago and it had increased to 6Mbps (better, but still not fast enough). Checked the "availability" webpage today and it now says "Max Plus -- up to 18Mbps." (I might be able to live with that.)

But I'm *very* concerned about the "up to" disclaimer as what one actually can expect is dependent on cable length & conditions. (It's an old neighborhood, all aerial cable from the VRAD to my house and much of the cabling is 60 years old.) I don't know the wire-length to the VRAD; I was once told years ago when investigating DSL that the cable ran in a "U" topology around my area to the cross-connect (the VRAD is right next to that) with the X-C on the end of one leg of the "U" and my house almost at the end of the other leg -- a *much* greater distance than "as the crow flies".

(1) So what could I *really* expect AT MY HOUSE from "Max Plus" U-Verse and how can I find out?
I do not want to drop Comcast, install U-Verse only to find it unsatisfactory (I also want HD TV pictures without visible compression artifacts) and have to drop it and return to Comcast (that would also be an expensive proposition!)

(2) Why, without my house or the VRAD being moved, did the advertised speed jump from "up to 3Mbps" to 18?

Your address was never green for U-verse when you saw "up to 3m" as your highest download speed. The minimum you qualify for on vDSL U-verse is 12M.

pair-bonding, probably. they used to install an iNID which would take two pairs and combine them for installs outside the distance window. since the new nvg589 has been released, maybe they can support 18mbps. I would post in the »AT&T Direct
forum, where AT&T techs can do qualifications of your address, etc.

I am subscribed to the 45Mbps power tier, and I get and sometime exceed by 1-2Mbps the advertised download. My Upload is ALWAYS consistent at 5.5Mbps. Did notice however that when 4 HD IPTV streams are going, that my download drops to 30-35Mbps, since one of those HD streams runs over the WAN and not the ingress.

ALSO, U-Verse uses, "Transmissions use digital H.264 (MPEG-4 AVC) encoding, compared to the existing deployments of MPEG-2 codec on cable and the discontinued analog cable TV system."
LONG story short, HD is better on U-Verse!

There's a wealth of info here: »AT&T U-Verse FAQ

Not so sure about that, unless there has been an update since I left.

I'm going off what is in the white papers. And the current codec is better than Comcast's codec. At least in my opinion. Compare a Comcast HD channel to its counterpart on U-Verse and I can even see the differences on my 7 yr old 42" Panasonic plasma

Hmm, that old "up to" qualifier. Has been talk that "up to" meant a vague minimum around 70%. (One for the FAQ if not already there). That they just drop your tier down if you call them on it and they can't correct your line to get your speedtest up to about 12.6M (70% of 18M in this case).

But... maybe that's only on lower speed tiers? On a TV-capable tier, you have a greater profile speed (24M for the 18M HSI tier), with the excess 6M usable only by TV/voice. And believe posts ( NormanS See Profile comes to mind, in comparisons with Sonic) have implied profile MUST sustain full 24M: it's a *hard* threshold (else you don't qualify for that tier; no 70% minimum comes into play)?

But folks until only two week ago *always* still fell short by 5-10% of their rated HSI tier (even though the profile MUST by definition sustain the full 24M profile). I gather ATT *was* indeed just being a dick and shorting us on our HSI because they could, justified by their ever present "up to" weasel-room language.

Anyone know if the TOS clarifies or defines what "up to" means? (FAQ needs link to the TOS too if not already there).

from the ATT Uverse Internet TOS
AT&T High Speed Internet Service a. Speed. The Service is composed of narrow band or broadband access to the Internet provided by AT&T. The Site, provided by AT&T and Yahoo!, is composed of a broad selection of on-line resources including email, communication tools, forums, shopping services, search services and personalized content and branded programming. AT&T offers many broadband service options, each of which has a unique Service Capability Speed range. The current speed ranges may be found at

The speeds identified at

»att.com/speedtiers

network interface device at your home, office or apartment building to the first piece of routing equipment in AT&T’s network. Service Capability Speeds should not be confused with Throughput Speed, which is the speed at which your modem receives and sends Internet access data (“Throughput Speed”). These speeds may vary and are not guaranteed. Throughput speed depends upon many factors including customer location, destination and traffic on the Internet, interference with high frequency spectrum on your telephone line, wiring inside your home, office or apartment, the capacity or performance of your computer or modem, the server with which you are communicating, internal network factors, and the networks you and others are using when communicating. In order to provide a consistently high-quality video service, AT&T Uverse High Speed Internet throughput speeds may be temporarily reduced when a customer is using other U-verse services in a manner that requires high bandwidth. This could occur more often with higher speed Internet access products. AT&T may periodically introduce new speed ranges or revise the existing speed ranges. Because these new speed ranges may become available before this Agreement is updated, you should check www.att.com for the most current product information. For purposes of clarity, this Agreement applies to all speed ranges offered by AT&T, even those which are not specifically identified above.

This is my Uverse review from a recent install vs. Directv which I had for over 4 years and from a recent move could no longer get.

Uverse tech was the best install I've ever had. On time, early actually, knew his stuff, did great work and even put on booties as not to dirty up the carpet. 10 out of 10 on the install.

Uverse picture quality vs. Directv....Uverse is soft on most channels...well, much less sharp than DTV was and I do see some pixelation with movement on some channels. DTV never had pixelation on any channel and had razor sharp pictures.

Equipment is a Uverse win hands down. Receiver is MUCH faster than my DTV DVR ever thought about being. Actions happen almost instantly.

Love the ON Demand features too. Just wish the PQ was as good as DTV.

My only gripe about Uverse is that I can't use my own internet with the system. I have to use Uverse internet to get the advanced features or I lose out. DTV of course accepted any internet into their units. My current IP is just fine and have no intent on switching to Uverse internet anytime soon. Oh well.

Hope this helps anyone with their decision.
