Nebula company is linked to a wrong article
Currently Qwest is offering both internet and television services over VDSL in the following markets:
* Denver, CO * Phoenix, AZ
Can the text "No fair-use policy" be changed ? It suggests some kind of lack of fairness, which is misleading. This is used in the description of the provider T-2 .
I currently live in Tokyo and NTT now has 100 Mbps VDSL/FTTH. I have it in my apartment, and watched the technician perform several speed tests where it was clocking an average of over 70 Mbps.
I changed the Q2 2006 to Q2 2007 in Netherlands, because Q2 2006 is in the past.

Verizon FiOS Reference in US
"Verizon offers it's FiOS service in some metropolitan areas at speed of around 30Mbit or higher, depending on line quality. The Verizon service is based on FTTN, Fiber to the Node."
First, FiOS is true FTTP, not FTTN. Second, except for a few multi dwelling units, Verizon uses standard CAT5e ethernet or coax using MoCA to deliver data from the ONT, at a rate up to 50 Mbps is some areas.
I have cleaned up the Verizon reference, and specified that VDSL is only used in MDU situations. Toddyboy711 15:08, 28 October 2007 (UTC)
Openreach UK Service
Reading the paragraph about openreach services it appears to imply the 80/20Mbps service is VDSL while strictly it's VDSL2 (I have it myself and can confirm this), certainly this should be obvious to someone who read and took in the rest of the article as it is specified that VDSL only supports speeds of 55Mbps downstream just seems to me there is no guarantee of that and it's quite possible someone could visit this page specifically to look at the deployments say to see who might provide such services. Granted it's possibly hair splitting a bit and am not sure if it was written that way for the sake of simplicity and brevity so not inclined to just go rewrite it without checking.

Removal of "Supply"
Anyone agreeing with me on the removal of the "Supply"-section. I find it superflous, not adding anything interesting to the article. If anyone do have intricate knowledge of the technology, there should be added more technical information. --220.127.116.11 (talk) 07:49, 4 October 2010 (UTC)
- Yes, it does seem dated and unevenly sourced. My guess is the "currently" sometimes means 2006 for example. The problem is that then there would be not much left! If it is going to evolve into a description of the technology itself, then I would suggest a merge of G.993.1 as a first step. I do see G.993.2, for example just redirects to the more common name. One encyclopedic sourced article would make more sense in my opinion. Asymmetric Digital Subscriber Line 2 Plus goes the other way, which seems odd, but is still one article for both common name and standard number. W Nowicki (talk) 17:42, 28 August 2011 (UTC)
Turkey listed in Europe, not in Asia?!
Why is Turkey listed in the list for Europe (in the "Deployment" section) and not in the list for Asia when about 95% of it is in Asia?! --Лъчезар☭共产主义万岁★ 08:21, 11 January 2013 (UTC)
Ranges and Cable Types
In the introduction, it stated that for VDSL2 "The maximum available bit rate is achieved at a range of about 300 meters" and for VDSL it stated the maximum bit rates for twisted pair copper wires and coaxial cable.
Can the VDSL2 bit rates be included for each cable type and the ranges at these maximum rates can be achieved for both VDSL and VDSL2 and for all cable types?
