| Constant disconnects... Need help
Hi all I'm new here. I'm currently running Dry DSL in Ajax / Pickering (band C). However my DSL has been dropping pretty much constantly for the last two days. This problem first started occurring a few months back. The problem would go away for weeks at a time then return.
The DSL would fall out of sync every 5 to 10 minutes and I'm forced to either redial or keep waiting until the signal gets back.
I've called tech support a few times and even had an electrician come look at the lines, everything appears to be fine, yet the problem continues.
Can someone give me any suggestions? The email I got from TS says network maintenance is during midnight to 6am, yet my DSL is dropping during day time... Any help would be appreciated. |

The modem I use is D-Link DSL 2320-B set to bridging. The router is a D-Link DIR-615. |

He wants you to post your line stats, AKA your sync speed, the errors, and all that good stuff you can find on your modem's infos page for your DSL connection. |

I'm not entirely sure the meaning of your links. I assume you simply wanted me to post a picture of the ADSL status page? I already have the manual with me (came with the modem).
For future references, please assume I can't read minds...
Here's a screen grab from the modem. If you need different stats please tell me.

| Your attenuation figures look good at 22 and 24.5 respectively. (You should be able to get a solid 5MEG.) However, the SNR margins are borderline for upstream and not much better for downstream. It's quite likely you have a line/loop problem. Could be internal or external for all we know at this point.
You haven't mentioned how the modem modem is connected. Is it connected at the demarcation point, or somewhere else in the house? How long is the cable from the modem to the line?
If you have a newer syle NID, connect your modem directly there and repost those stats.
You may benefit from using a ST516 modem as well. |

| The stats are from within the house. I will try to get the stats by connecting to the demarc point. The lines are short.
I don't have a laptop so it'd take me a while to take stats from outside the house (where the demarc is). However just out of curiosity, what does a "line/loop" problem imply? And what kind of repairs would be necessary should that be the case?
Thank you for your help. |

1 edit | By testing directly at the demarc/NID, you rule out internal wiring problems. Wiring over time can degrade, and jacks can go bad.
The loop is generally referred to as the pair Bell provides to/from your house to their CO. This loop typically goes through many submerged and sometimes aerial portions, and it is cross-connected along the way (those brown boxes at the side of the road). There are many issues that can arise in this loop, as you can imagine.
If you find your stats improve dramatically at the NID, you know where the problem is. It's usually best to have the modem installed as close as possible to this demarc point, and then feed your house network via Cat5e/6 and/or wireless.
EDIT: as for your testing at the NID, just run a long ethernet cable from outside to your computer inside. That way you don't have to drag it all outside. G'luck!

The SNR for DL improves 3 fold, hovering at 30 or so, while the UL stays the same. Not sure what it means.
As for dragging a wire (cat5 or otherwise) it is impractical since I would have to leave my junction box open, hang a line all the way up to the second floor, then go in through the window... I don't have the tools to complete such an operation, and I don't think it's a good idea to expose the junction box wiring to external elements. Can telephone wires even survive the Canadian winter?
Any other possible solutions? (Or is this even the source of the problem? Should I be getting same SNR inside and outside?) |

| Definitely IKNS.
It's possible that the modem could confirm this as follows:
telnet
admin
admin
adsl info --vendor
The US SNR (6) and US Atn (24.5) are obviously bogus.
But if the DS figures are to be believed, the signal is 6 times stronger at the demarc and the SNR is 85 times better.
TSI support should be able to get the actual line stats.
Perhaps poor and fluctuating line conditions, aggravated by IKNS intolerance result in sync failures?
BTW, the following command should display line errors:
adsl info --stats |

Hi,
Are you sure you wouldn't like a fortune teller?...
The linked thread suggests that you'll have three
3rd-party utilities available for your brand/model,
that's all. Your attenuation levels seem odd (the
UpStream side is fainter), which may confirm that
you're on a "remote" already so i feel it might be
safe to predict you'll be lucky in a close future...
You can contact me if you wish to "trouble-shoot"
using long-term averaged "noise" curves... ...or it
may be more tempting for you to try other tricks...
Life isn't always simple when there's crappy wiring
in the middle and it's not clear where to begin!...

Improvement!
Comparing the original to the demarc, notice how your upstream is now synced at 800 instead of 640? Your downstream SNR is vastly better too!
5056/800 is what you're supposed to get.
And yes, it looks highly likely that you're on an IKNS remote.
This confirms that your internal wiring is the source of the problem. Start checking jacks and removing devices. Add things back 1 at a time to see if you can figure out the main source.
Gluck.
EDIT: If you plan on staying with DSL for a while, it may be worthwhile to invest in an ST516 modem.
If you can clean up your internal wiring, you may be able to move from interleaved to fast path. |

He could be on it already, isn't always reporting interleave the other glitch with the IKNS remotes? He's most certainly on one, the upstream power would be bumped up if it was really that bad.
Try a tracert, 10-20ms first hop mean fast path, 30-40+ means interleave. |

@Gokuu:
No clue what IKNS remote is or what it implies.
Regarding the wiring, there are no devices attached to the dry loop DSL line as far as I know. The DSL seems to be on separate lines. Should I unplug all the phones in the house hold and review the stats?
And how do I "clean up" my internal wiring?
As well, what additional advantages are there with an ST516 modem?
Thanks.
@everyone else:
Sadly I'm nowhere near as competent on technical jargon as the rest of you seem to be. I do not understand most of what you guys wrote. |

| Something I forgot to mention (probably amnesia due to old age), I'm on the Roger's Home Phone service, which uses their digital network. This is the reason why I said I doubt there are devices on the same line as the DSL.
I no longer have a working Bell phone line in the house. This is the reason I had to utilize dry DSL in the first place. |

Ok, so Rogers home phone comes in via RG6 to their modem device, which is then connected to your house wiring.
I then also assume your dry loop comes in from Bell and is connected to your entire home wiring as well, or is it just one jack on the other floor? If it's for the entire house, then you're probably using the same home wiring, but using the OTHER pair than the ROGERS home phone is using. Residential phone wiring typically has 2 pairs in it (red/green and black/yellow).
Take some pics for us showing the dry loop demarc and the Rogers setup.
The ST516 is widely used here by many of us, and could very well be regarded as a "defacto" standard modem in use. You will be able to use a graphic DMT tool for line stats with the ST516. Its chipset (Broadcom) and the right firmware has proven to be beneficial in many instances. In your case, it *could* help with the resets, but I would get your wiring in shape first.
Cheapest place to get the ST516 is here:
»www.caneris.com/Hardware
Or you can find them at Infonec.
