Re: DSLXtreme Experience So Far
I was reading that 52 is a "poor" - but maybe I'm missing something?
I guess my question is - do my numbers suggest I could get fastpath and does DSLxtreme offer it?

Ok, I'm having a lot of flux on my line - but mainly my problem is with upload speeds. I have the 3000/768 package and my modem shows that I can get 768 - but I'm always just getting 640 or roughly around there. My upstream/downstream SNR ration is out of whack - why does that happen - and is there anything I can do about it and should I open a ticket?
Shouldn't I by syncing at 768 upstream when my modem says I can?
Here is what I'm showing right now:

Actually, right now it's showing 756 - weird - but anyways, shouldn't I be getting that atleast with the 3000/768 package?

| The lines are typically rate adaptive and will sync at the highest rate that they can hold without losing sync within the package limits. The highest on the downstream that Verizon will sync you at is 3360 and on the upstream is 864. It looks like the line is holding the full 3360 on the down but isn't able to obtain the full 768 on the up. It is therefore rate adapting down to 640 in order to hold sync.
Do you have access to the MPOE to plug the modem in there and see what the line will sync at?
Thanks

Hi George,
Yep, I do have access and I've solved the upstream/downstream ratio problem... I'm running cat-5e directly from the NID into the modem. I also replaced the old terminal that used "posts" to terminate on with a clean jack on the outside of the house.
As you can see - things do seem to be deteriorating slowly (based on the stats I've been posting since the Verizon dudes were here)... my max sync rates are getting lower. Latency has been excellent... But what do you think is happening? I'm not getting a very good upload speed at all - and that's super important to me since I do a lot of remove administration for work.
Here are the new stats (with modem plugged directly to NID):

| Your SNR Margin on the upstream is slightly marginal which would likely be the cause of the DSLAM rate adapting down. usually when it is issues on the upstream it indicates a problem on the far side close to the home. Could there be anything at the house that could be generating noise on the line? Sometimes halogen lamps, dimmer switches etc.
Where those readings directly connected to the MPOE?
Thanks

Hi George,
I've phoned the other George (the dsl guy from Verizon who gave me his card) and have told him the problem - I left a message - hopefully he'll call back today.
Those readings are from a direct connect from modem -> NID.
If he doesn't call back, should I open up a ticket with you guys?
There shouldn't be any issue with lamps, power, etc...
I'll give it a couple more days - see if I can resolve the problem directly with Verizon myself - and if I can't get through to the proper channels I'll escalate it to you guys, cool?

| Yes, you would want to open a ticket with us directly. Under normal circumstances that would be the right course of action. Since this technician has been extremely helpful for you I am not opposed to seeing what he has to say though.

Hi George,
I talked to him and he said the best course of action - since it may require some time and he needs to account for it - is to open a normal ticket - but he agreed - based on the readings I gave him there is something wrong...
So, I'll open up a ticket right now and I'll also link to this thread.
Cool?
Thanks for all the time you guys have helped me with this - totally appreciate it. I personally think the customer service at DSLExtreme is awesome!

George,
I opened up a ticket. The ticket id is: 3556020
Hopefully we can track down why my upstream is so messed.
- Marco
PS: I've never been able to sync at 768 - the closet I've gotten is what you've seen reported on this thread. |

Ok, here is an update:
The Verizon guy who came out for the dslextreme ticket I opened just left.
Several things:
1. the cable bundle outside my house that runs in the ground is a problem spot he said - it fills up with moisture and Verizon knows about it - they aren't going to dig it up and replace it.
2. He said when he got to my house and measured the pair I was on he could hear a horrible hum. He said he found the best pair he could find and hooked me up to that.
3. My SNR has improved on the downstream quite a bit, but my upstream is still the same. He told me it just isn't going to get any better then what I have now - but he did tell me that with the new pair I'm on it should be stable - but that I should keep checking it to see if it's affected by the moisture in the morning, etc.
Here are my modem readings at 10:54 AM today:
Mode: G.DMT
Type: Interleave
Line Coding: Trellis On
Status: No Defect
Link Power State: L0
Downstream Upstream
SNR Margin (dB): 16.2 10.0
Attenuation (dB): 52.0 31.5
Output Power (dBm): 16.8 11.9
Attainable Rate (Kbps): 6944 780
Rate (Kbps): 3360 672
As you can see, my upstream's max is 780 but the modem is synced at 672 because there probably isn't enough headroom at 780 to stay synced at 768 reliably. That's fine, I'd rather have 672 stable then 768 unstable - but I wish I could have what I'm provisioned for. :-( Those extra kilobytes/sec are precious when having to upload massive files).
So, I'm not sure what else I can do. If there is a known problem in my neighborhood with the copper trunk getting wet, etc. - and Verizon doesn't feel the need to replace it - DSLExtreme can't really do anything about it - so it's not their problem.
By the way, DSLExtreme has phoned me everyday since I created the ticket and has followed up promptly. Great job, guys!

Ok, this is NOT good. The line was holding at the values I posted above, but now it's 5:00 PM and I'm losing sync and dropping all over the place.
The values now for the downstream have dropped all the way to 4 and go up to 9 and flux between 4 and 9 - right now as I refresh the modem's ADSL page I can see it is at 7.
Obviously there is something wrong with the cable trunk that I'm on - because this is exactly what happened before the Verizon guy came today - I'm just on another copper pair.
So...
NOW WHAT DO WE DO?
If Verizon won't fix it (and the guy who came today admitted they are out here all the time in this area fixing that particular bundle) is there anything DSLExtreme can do to help?
I'm actually starting to worry a little bit. Connectivity is a big part of my livelihood... It just kills me to see fiber running by my house and just because I live in a condo with a housing association I can't order it...
For the record, the guy who came today was nothing like the guys who helped me out the other day. When I asked him, "so is this going to solve my problem?" - he said, "well, it's holding now - but it may change throughout the day. You'll have to check it." That wasn't very reassuring.

| You're being punished for giving money to Verizon (by way of DSLX). When I had landline service, dialtone would disappear completely on rainy days...it took four visits by different Verizon techs before one of them noticed that a backyard tree branch had grown completely around one of the phone wires! They switched me to a different line but never talked about fixing/replacing the piece of wiring that was now running through a tree (and yes it's still in the same condition).
This is why I won't support Verizon by patronizing their FIOS service even though it is available in my neighborhood. |

Hi Zak,
I went ahead and power cycled just now before I replied to you to give you the readings after I did that:
Mode: G.DMT
Type: Interleave
Line Coding: Trellis On
Status: No Defect
Link Power State: L0
Downstream Upstream
SNR Margin (dB): 8.1 10.0
Attenuation (dB): 52.0 31.5
Output Power (dBm): 19.4 11.9
Attainable Rate (Kbps): 4064 776
Rate (Kbps): 3360 672
K (number of bytes in DMT frame): 106 22
So, no, it's just horrible. The modem just keeps downcycling all the way to oblivion until basically my highest attainable rate is lower on the downstream then on the upstream...
Can you guys contact Verizon?

Marco,
We would need to send out another Verizon technician to your location. If that was the best pair that they had available they may need to downgrade your speed tier in order to keep you stable.
It is odd that your downsteam remains fine but your upstream is adapting down. This usually indicates a problem with inside wiring or at the far end from my past experience. I believe you already tested from the MPOE though correct?
Thanks
