Re: IP-DSLAM 3.0 and continuing loss of sync issue. said by Tanshin:The battery backup also serves as a surge protector/ in line transformer thing of sorts to regulate the current going into the modem. I don't feel like looking for it, but somebody actually tested between the power cord, battery Rev. A, and battery Rev. B to see if different sources affected connection, and they did (Rev. B being the best, although it was also tested on a 3801, which the Rev. B is designed for). Both batteries caused an increase in max throughput and, I believe, lowered uncorrected blocks count when compared to the power cable alone.
Yes, my understanding is that it will compensate for any voltage drop on the line. That was the reason it was originally given to me by the AT&T tech.......in the odd chance that my house has voltage issues of some sort, and in the event of a voltage drop, the battery backup would regulate the voltage, like you said.
But, I got the same results last night when it was plugged into a completely different cicuit than the scanner, so the entire voltage drop theory seems to be wrong, but that's my assumption. |

kudos:1 | Makes me wonder if electricity is either feeding into your lines, or if the interference is just getting in somehow. I know we had an issue with our phones that was fixed when we traced one of the lines. It wasn't connected to anything and was touching a metal shelf in our basement. Disconnected it and the problem stopped. |

It seems the shielded Cat5 would stop any interference though......that's one thing that's confusing to me.....if it is simply interference. |

I talked to the latest tech that they've had on my problem today, and told him about the scanner phenomenon, and he agreed that it's a separate issue from what this thread has mainly been about. The good news is he thinks that issue may be resolved with the latest repairs and changing the DSLAM I was on. We'll see.
Anyway, he said the same thing as a guy I know at an electrical supply house, that seeems pretty knowledable.......that the scanner seems to be putting out some harmonic frequency that is getting into the electrical of my home.....and that it could affect the hot, nuetral, and ground, so it's feasible that the battery backup wouldn't stop it. That was the opinion of the tech, and he did say, "but I'm not an electrician". He said they had an issue with a customer once, where every time the guy turned on this spare computer, the modem would crash. It took a few visits before the guy realized the possible correlation, but they tried it, and every time he turned it on, down went the modem. In his case, he had it checked, and it turned out to be some diode in the modem, and he had it repaired.
Anyway, he didn't think it was something you can "fix", just a weird phenomenon. Again, just his opinion, but hope he's right, as the scanner is out of here anyway. Maybe the fact that is on the fritz is why it is putting out some weird frequency too, it's hard to say. I know an electrician I can call, now that I think about it, that would be nuetral on the whole thing, with nothing to lose or gain, and I'm curious what he will think of this theory. |

kudos:1 | Well hopefully these things hold up so we can put an end to all this :P
I am definitely interested in what an electrician would say about this though. |

I agree on both points.  |

| The other thing that still bugs me a little is the fact that AT&T ran a #6 ground wire from my NID to a ground rod they put in, and also ran another #6 wire from my house main ground to that same ground rod. AT&T has been the only one that says that's an o.k. way to do that. I keep hearing it can cause more problems than help, sometimes. I've been told I only need the one wire coming from the house ground to the NID. *shrug* Not that it has any connection to this weird scanner issue, but overall, it might.....I just don't know. If I cut the one wire, and just run the one from the house to the NID, that tech might come back for something, and see it, and say I'm interfering.....who knows? He thinks changing my DSLAM and the other repairs is going to be the solution, so we'll see in a week or so. I have my fingers crossed. The one thing that has been consistent the last couple days with all this unplugging of the RG is that it keeps syncing back up in the 8 meg range, give or take. Before it was syncing up all over the place every time it came back up from a drop.....anywhere from 4-8 megs, so hopefully that's a good sign. |

| Not trying to hijack your thread but just wanted to say we just got IPDSLAM for a customer and it was working fine until tonight and now the connection is bouncing off and on every few minutes. ATT tier 2 said he was getting bad results on the lines and said they are over 11,000ft from the office. They are going to send a technician out to check it. If they can't fix it soon we'll just have them drop the service as they can't afford this much down time. I'm thinking about emailing the uversecare email. |

Did you ever get the issue resolved? |

| said by networKnoob:Did you ever get the issue resolved?
It appears so. I haven't been back here for a while, obviously. The last thing that was done, about 4 months ago now, was they changed the drop from the pedestal to my house, and changed the pedestal, and grounded it better than it was, which was not at all. They also changed the DSLAM I was on, whatever that means. It's hard to say if it was one of the three last things they did that cured it, or all of the above, since those three things were all done in a day or two, and it hasn't dropped since. We had power go out a couple times, and one time they upgraded the firmware on the network, so I saw that "flashing red light" a few times not long after the last work was done, but it's different when you know the cause. I got so used to seeing it over that 5 month period, I still sometimes expect to see it.
I have it on a battery backup now, so any loss of sync would not be from power loss, just so I can rule that out if I see any record of loss of sync, but it's been 83 days and counting, and like I said, before that it was from loss of power and a firmware upgrade, so it's actually worked the way it should since the last tech was here. This guy was a "think way outside the box" type of guy, and he said he's the one they send when no one else can find the problem. Can't help wonder why they didn't send him sooner, but at least he fixed it. He was around #20, and that was after 5 months of dealing with it. It does what it's supposed to do, I doubt it would handle the 6.0 Tier, but that's o.k.........when my financial situation improves, I want to switch to cable anyway. It will eat this for lunch, and they'll probably never have the real HSI in my town. Here are my stats, FWIW. |

| Kind of funny how I wandered back here and posted that I haven't had problems for about 4 months or so, and it appears to be solved, and it may very well be. But in some kind of evil irony, or hopefully some weird coincidence, today I lost sync twice in about an hour. Must have jinxed it by posting here. Or it's just the same crap rearing it's ugly head. The difference is, there is no way in hell I will watch this service lose sync over and over, and call and listen to anything AT&T would have to say. I put up with WAY more than most rational humans would even think of putting up with , back when all this was going on. Start this pattern again, and my IP-DSLAM and land line are gone, and it's hello Comcast. It's that simple. They only give me the promotional price because I have a land line, so getting rid of both will cover most of the monthly Comcast bill.
Hopefully it's just some weird glitch. |

Dude, I feel your pain - and understand right where you care coming from. I've been battling AT&T since June of 2011 and they still can't solve the problem. They have sent out over 18 technicians (same guys over and over) and still cannot explain why I continue to lose sync about twice a day and my neighbor doesn't.
AT&T is about the most worthless company it comes to for customer service. You might as well give up talking to the same person twice because it won't happen. Here we are January of 2012 and I'm still battling to get a charge for a modem taken off my bill (I've ben given every excuse in the book as to why it hasn't come off yet).
If I had any choice other than AT&T I would be gone. I wouldn't recommend AT&T to my worst enemy. They are the bottom of the barrel when it comes to customer service. |

I agree with everything you said, hands down. They are the absolute worst company I've ever dealt with, beyond the shadow of a doubt. I hate them. As soon as things pick up with my work, I will go to Comcast. It's nothing against the tech's.....they go with what they know, and the last guy really went outside the box, and actually stopped my loss of sync.
Turns out because he returned a phone call I had made to him one day, and talked to me for almost 30 minutes, he was suspended for 30 days without pay. They called it "misappropriation of funds". They said I never called him on the day in question. Apparently, if you call an AT&T tech on their cell phone, and it goes right to voice mail, it shows no record of the incoming call. Sounds like bullshit to me, but the union steward that is representing this tech said there was no record of me calling him. I found the call on my cell bill and sent it to her. It may end up in arbitration and I agreed to stick up for this guy, because he was a good guy, and shouldn't be getting shit on like this. He actually fixed the problem. I guess they don't call sending some of the same techs, that didn't know what more to do, a misappropriation of funds......and that's nothing against those techs. A few of them said they had no training with this IP-DSLAM. AT&T disgusts me to no end, and first chance I get, I'm gone, land line too. |

| The techs are the low men on the pole, and most of them do the best they can with what they have to work with -- which isn't much. When they installed this IPDSLAM stuff here the MANY techs who visited said they have received ZERO training on it, had ZERO equipment to test with and had ZERO ability to get any of the education or tools. Their best tool they had was an analog multimeter. That's it -- nothing else.
After I finally had it with the AT&T nonsense I complained loudly enough that they escalated my case and after two months they finally sent the techs a professional grade test kit. The tech who came thanked me profusely because they finally had some decent equipment to test with. It's a sad state of affairs when it takes irrate customers to get the proper tools for the techs.
We already dropped AT&T for our cell phone provider, land line is gone as of this month and the minute they finish the fiber build-out here in town (another organization finally came into town and started laying fiber after AT&T refused to upgrade anything that cost more than a $1.00) AT&T has seen the last red cent they will ever see from me.
Good riddens to bad rubbish. |

| said by dmxrob6:The techs are the low men on the pole, and most of them do the best they can with what they have to work with -- which isn't much. Yep.....I agree. Some tech's are better than others, just like anything, but for the most part, most of them that came here did what they could. The last tech was definitely an exception........really went outside the box. Then, they penalize the guy for a completely justified phone call to me, saying wasn't. What a joke. Corporate mentality at it's finest.
More than one tech told me it wasn't the same company that they started working for. |
