I have a 3/1 data connection as well as IPTV through them. The only problem is they dont have a set top DVR solution yet.

I do not qualify for Qwest's standard ADSL as I am over 25,000 feet away from the CO. But with a their VDSL I am 500 feet away from a fiber fed remote DSLAM.]]> http://www.dslreports.com/forum/remark,18491204 Tue, 12 Jun 2007 09:11:53 EDT Re: Why Fiber http://www.dslreports.com/forum/remark,18490585 koolkid1563 :

I would argue that technically, VDSL is a form of DSL.
Yes, it does use a form of DSL to the VRAD (DSLAM), I am not arguing that.

By the FTTN logic, most all cable would be Fiber as well, since the nodes are typically fed by fiber, which then connects via copper to the subscriber.
With U-verse, fiber is run all the way to the DSLAM (node), and copper the rest of the way. Right now, the copper distance from the premise to the DSLAM can not exceed 2,300ft (it has been reduced). How does this not fit your description of FTTN? From the CO to the DSLAM sitting no more than 2,300ft from the premise is all fiber. Every VRAD has a DSLAM inside, and every VRAD is serviced by fiber.

Standard ADSL in a remote cabinet (like the one my service uses) can be fed from fiber as well, but that doesn't turn my 3 mile long rural 1.5 Mbit service into FTTX any more than VDSL at 500 feet does.
That is true, and you make a great point. The only thing is, I don't know of any ADSL/ADSL2+ modem capable of speeds even close to VDSL/VDSL2. There must be a big difference somewhere in the technology feeding the two. I don't know of too many ADSL providers advertising it as FTTN, even if it is serviced out of a RT fed by fiber.

Call it what you want, but, I think AT&T is on to something. Are they the only company doing this? No, Qwest is doing the same thing, and I think they are even using VDSL to provide their IPTV services too.]]> http://www.dslreports.com/forum/remark,18490585 Tue, 12 Jun 2007 03:34:38 EDT Re: Why Fiber http://www.dslreports.com/forum/remark,18274153 LostInWoods : I would argue that technically, VDSL is a form of DSL.

I refuse to drink AT&T's Kool-Aid on this one, koolkid.

VDSL from a remote cabinet (be it on the side of the road or MDU basement) still delivers data to the subscriber over a copper pair, just like regular old ADSL.

Traditional ADSL runs on the PSTN system to the CO, VDSL rides the existing copper wire to the VRAD (DSLAM). The current local loop limit is 2,500 ft from the premise to the DSLAM for U-verse. Then it is fiber from the VRAD to the RT, then a fiber trunk to the CO.]]> http://www.dslreports.com/forum/remark,18270590 Wed, 02 May 2007 17:00:28 EDT Why Fiber http://www.dslreports.com/forum/remark,18268925 LostInWoods : Why is this listed as a fiber connection.
