Re: Protesting too much? Our ADSL2+ cards cost less than our legacy ADSL cards. ( about 5 times less at the time of purchase )
Our line maintenance also went down ( did I mention these cards are fantastic on crappy lines? )I don't see how one could possibly incur a increased service cost.
Truck rolls = $$$
Even the modems are purchased customer side. |

How do they do on 20k+ loop lengths? |

| Depends if your ISP supports line bonding. All ADSL2+ cards support line bonding right out of the box.
We don't support it, so we have a cutoff of about 18K. We do support VDSL2 pair bonding though.
With the mass defection of POTS we have plenty of pairs to go around, so why we don't support ADSL2+ pair bonding is a mystery to me. |

Not sure that those spare pairs are all that common in the places with long loop lengths and zero density, like Kettleholm, which is about 3-4 miles from Lockerbie. Wouldn't be surprised to see plenty of phones still running on DAMLs, PairGains, and ISDN extenders.
The reason you don't see ADSL2+ pair bonding is called "U-Verse".
Sonic's Fusion offers ADSL2+ and pair-bonding. Reports are mixed.
Some users indicate speeds are slower than ADSL, and MUCH slower than theoretical speed charts state. But it doesn't really matter now that Sonic forces new subscribers to buy dialtone. |

Our new JDSU test units already have the port and testing tools for 2 pair ADSL2+ |

But what LEC or ISP will offer it?
What performance gains will a customer actually realize other than slightly increased upload speed?
(Referencing Sonic's product, which is rather underwhelming.) |

And people beyond 18K to about 25K could now get service.
Do you currently have sonic.net's bonded ADSL2+ service? |

Santa Monica, CA | We don't have Fusion yet, though it is promised "soon".
We're at ~15k feet - the line varies, sometimes will qualify for 1.5M, but historically maxes at about 650kbps, with typical speeds of 480kbps.
I'd like to think that Fusion / ADSL2+ can deliver more than 3mbps, but I'm not optimistic. |

| Are you on ADSL? Or ADSL2+?
ADSL2+ typically performs better than 650k at 15K. |

We have ADSL.
My concern is that despite all the hoopla, their ADSL2+ product doesn't perform at anywhere near the advertised speeds for many, but those of us coming late to the party DO enjoy the privilege of paying an even higher price for less-than-mediocre bitrates and dialtone we don't necessarily want. |

2 edits | I can tell you ADSL2+ outperforms ADSL in 2 ways.
Firstly, it mitigates noise better. Secondly instead of using 1.1Mhz it doubles bandwidth to 2.2 Mhz. (VDSL is 12Mhz)
Now at 15K all bets are off as to whether or not you see any of the additional bandwidth |

Unfortunately, the "upgrade" is a roll of the dice, pair-wise, so the improved protocol doesn't necessarily yield anything, and none of the king's horses or men are interested in coordinating a fix if you draw the short straw.
We'll still give it a roll at a few sites, those that still use hardwired dialtone, providing it comes available real soon. $55/month for ~1-3mbit and voice isn't anything to write home about, but I'd still rather give Sonic a shot at it before yielding to U-Verse or cable. |
