Kernersville, NC | This DSLreports article is incorrect. This article is wrong.
VDSL2 offers speeds of up to 100 MB, not 25 MB as stated. Look at the graphic charts that were posted. Someone make an error.
ADSL2+ is the technology that offers 25mb per bonded pairs. |

Just not at distances where people may actually live. |

| Some tidbits about SBC's VDSL/FTTP rollout strategy:
For everyone: the pronto RT network optic interconnects between RT and central offices will be upgraded to gigabit speeds.
For new housing/buildings: FTTP: each residence will have a battery backup equipped ONT (Optical Network Termination) with 4 POTS, 1 data and 1 F connector for video. lots of room to grow, if you live in a swank enough neighborhood and bring home a high enough salary for Whitacre and his cronies to deign to dole out the good sh*t.
For the rest of us: FTTN: they'll run fiber and power from the existing RT's to the cross connect boxes (aka "B boxes")to feed mini nodes that will fit on the existing footprints of the original cross connect boxes. In telco terminology, they're cutting out the F1 (main feeder cable) and the F2 (the run between the F1 and the customer's premises) will now be 2Kft or less. And they're also having technicians dedicated to going to all the cross connect boxes and cleaning up F2's in preparation for the rollout of FTTN.
So, for all the chicken littles crying about how they're not within 1-2Kft of an RT, go find the nearest crossconnect box for a rough estimation of how far your copper loop will be. there should be one within a block of your house or apartment complex. Some apartment/condo complexes will also have mini nodes on site, making the copper loop very short.
Overall, I'm still extremely skeptical of Whitacre's claims of being able to squeeze HDTV and SDTV, video on demand, 4 dialtone and high speed (the talk I've heard for up/down speeds makes me weep, it's not that much better than regular Pronto DSL) data over copper. It might work, but I predict the quality will suffer noticably.
Verizon has the right idea: upgrade the ones who want it, regardless of whether they're existing structures or "greenfield" structures just starting to be built. |

To me, if you have distance limitations, then your technology is already outdated |

What is really interesting is that my mother in law has an older house, and just recently got fiber to the house installed by SBC. She has a APC battery backup box in her living room. Maybe it has something to do with her living in the "Telecom Corridor". Maybe they are doing some testing there... SBC just sent her a notice by mail that on this particular date they were going to install fiber. She has the option to use the fiber for her Internet connection but she is currently happily using Comcast (cheaper if I recall correctly) so she is only using it for voice service right now. |
