| Bonded customer An ATT tech was recently working on the lines in our area. I asked him if we could get Uverse. He checked the signal and said due to the distance from the box/node we would need to be a bonded customer. I failed to ask him what that meant. Does anyone know what that means? |

1 edit | VDSL has an average range of around three thousand feet from the VRAD before the signal's maximum speed drops below the required minimums needed to sustain service. What bonding does to get around this limitation is use two lines that are combined to form one connection. For example here are the stats on my bonded u-verse connection:
Line 1 = 27Mb
Line 2 = 26Mb
-------------
Total = 53 Mb
Since the service requires at a minimum of around 30 - 33Mb connection, one line could not provide enough bandwidth to sustain the lowest profile offered by Vdsl U-verse (Lowest being 25M profile. There was a 19M profile but I'm pretty sure they aren't offering it anymore).
So if you were to get a bonded U-verse setup this is what you could expect:
- Up to 18Mb down 1.5Mb up internet connection
- 4 simultaneous television channels (3 HD / 1 SD)
The cost is the same as someone who has a single line configuration. The installer will mount a box on a wall outside of your home where the bonding will occur (generally next to the NiD). From there there are two lines run into the home, one which carries Tv signal and one that carries internet. If you have any further questions just ask! |

| Bonding lines does not increase maximum speed it reduces resistance. Reducing resistance allows for higher freq to pass thus allowing faster speeds. Faster speeds operate at higher hertz freq. A single speed profile has nothing to do with a customers ability to get service. In this instance the OP is beyond the resistance range for a single twisted pair there by filtering the needed freq. To overcome this bonding another pair will reduce resistance and allow the freq to pass. Refer to OHMs law. |

And the end result is that a customer with a bonded connection is able to get faster speeds. |

Two independent DSL lines are provisioned on separate pairs and the traffic combined into one virtual link by the DSLAM and CPE at either end. It does not physically tie two pairs together to reduce resistance. |

they still offer the 19m profile thats what they offered to my family on another block but they kept cable |

Hmm, really? What is the resistance of one line and what is the resistance of two bonded lines? |

Would the quality/speed of our service be worse than a home that is not bonded or the same? We are thinking of getting TV and internet. Should we use our existing wireless router if we get Uverse or use ATT's RG?
Is it ok to use the existing RG6 cable in the home or should we have ethernet cable run throughout the house? |

I'll preface this with the qualification that I'm not on a bonded connection.
My Uverse install is connected through 18 year old RG59 cable with a balun installed at the NID outside my house. I have the triple play bundle with 2 TVs, 3 wired phones, and a Netgear switch that connects to 4 PCs and a networked printer. I have the 12/1.5 speed connection. No problems with any of the services.
As always YMMV.

+1 and you are correct.
(coming from the guy that can look up at the sync rates on both lines from inside.  )

No, the "bonding" is done at the data link layer, not the physical layer. Refer to VDSL/OFDM specification.  |

The download speed of a bonded pair on a 25m profile is the same as a single pair on a 25m profile (Max 18Mb download speeds). However, the upload speeds are a bit lower, which I believe is the reason why bonded pair installs are limited to the 25m profile. In comparison, many single pair users can get a higher 32m profile. This offers a 24Mb maximum download speed as well as 4HD simultaneous viewing channels (and greater upload speed).
As for using your own wireless router; here's the deal. You must use the supplied ATT router with your U-verse service. However, if you want you can add your own wireless router behind theirs for wireless access to your network. Many people do this because the ATT u-verse router is limited to wireless G and they would rather have wireless N speeds.
As to your question about using existing coax, your installer should be able to determine if the quality is good enough to use or not. Or you could use ethernet cable if you choose. Either option will work just fine. It's just a choice of preference.
I don't want to overload you with a lot of techno babble so let me just say this. U-verse bonding works just fine. All you need to know is that is has a maximum download speed of 18Mb and that you can view a maximum of three simultaneous HD channels and 1 SD channel. I can't comment on the voice service because I use Vonage.
Good Luck! |

Louisville, KY | Thanks Wingless60. We will add our existing router after the ATT RG if we get UVerse. I may have ethernet cable run to our TV with the XBOX. I think a hardwire connection would be better for it. |

Bonded pair installs can be a crap shoot. It's 2x the amount of equipment, connections and copper for 2/3 the bandwidth of a good Uverse install, but it can be huge benefit if your address limits your options and your up for the learning curve and growing pains. I would pull the trigger, and keep a close link to this board and the ATT Direct forum. |

If you have a neighbor who has UVerse TV I'd drop by and make sure you'll be happy with the picture quality. In my area it's total crap. However, in some areas people say it's decent.
Overall, I'd say most people are happy with it. If you've been spoiled by a really good cable or satellite provider you may just discover it's not quite on par.
Keep in mind that if you get it installed and don't like it, you can call within 30 days and have it removed without much fuss. |
