Re: Sheesh...
Ehhh, anyone with half a brain knows that AT&T decided to first invest in FTTN, then extend the fiber to homes, using active FTTP tech. To get PON, they'd have to remove all the expensive VDSL DSLAM's, and all the active electronics, and sell it in a market where few would be interested in buying, I.e., at the point that AT&T decides to go FTTP, their copper active electronics will be WORTHLESS. Also, to install the PON splitters, they have to make sure the existing fiber is compatible. Also, they have to replace the equipment at the CO, since it'll have to transmit to an entire neighbourhood simultaneously. Not to mention the cost and hassle of replacing the existing RG's and CPE with ONT's. AND paying for the splicing and whatnot labor that goes into setting up the PON. Verizon? They'll be milking their fiber by that time, while AT&T has to handle copper Re-Verse cancellations, and get people to switch to the 'revolutionary' PON infrastructure. Considering the hard time Verizon is having, even after doing it right the FIRST time, I seriously doubt people will switch to U-Verse, especially by the time Comcast starts rolling out DOCSIS 3.0.
Now, if you expect AT&T to just chuck the old stuff into the junk yard, that's a whole new point, but I doubt that's happening. They're likely going to go active FTTP, not PON. Except the greenfield installs, of course.
And I probably know a lot more than you do in your dizziest daydreams, so I'll take that for a (sarcastic) compliment. |

Huh? Why would they need to power a cabinet if they go to FTTP? They'd go PON. At that point the cabinet just becomes a major aggregation point.
And you only have one fridge sized box per neighborhood and really less boxes overall as crossconnect cabinets would be pulled.
You're talking a lot of points but you don't know the engineering. |

said by a333  :I'm not talking about the Greenfield installs. I mean that areas with pre-existing FTTN (aka cheap 99cent VDSL Re-Verse) will be a lot more expensive to maintain if and ever they are upgraded to FTTP, and have more aspects that can go kooka-dooka. (i.e. power, active equipment, waterproofing, more expensive repairs after calamities, etc...) As to the BPON installs, I pray that they offer something more than 6 Mbit/sec over the new fiber. The least they can do is match existing cableco offers. Also, to add insult to injury, the greenfield developments don't get DHCP, but are instead routed over the existing old and crappy DSL backbone. Sad........ currently uverse vdsl and uverse fttp have 10/1.5 for the max tier. Legacy fttp is still on pppoe and atm, but uverse fttp is on dhcp. |

AT&T FTTP is BPON and can be software upgraded to GPON. |

hell, even if they DO go to FTTP in future, it'll be a helluva more expensive to maintain, with all that active cabinet equipment to keep powered up and serviced. IMHO, VZ took the best approach, in using a passive network. Expensive, yes, but a LOT cheaper to maintain. Also, fridge-size boxes on customer lawns not included... |

U-Verse internet speeds are Crap. They seriously need to bump their top tier up to at least 30/5, but then you have distance limitations..lol Atat made a wrong choice going with dsl technology. It WILL bite them in the ass in the future sooner or later.
