It's a rural area, I think there is one other line enabled on the cabinet. I doubt it is crosstalk.

Bald_Eagle, is that event in the graphs you've generated for me?

[Bald_Eagle1]

From what I have read, depending where the pair is located in the bundle from the cabinet, a single crosstalk disturber can cause a loss of sync speed by up to 30%

Rural areas sometimes = electric fences, which can cause interference, possibly increasing when an animal touches one of them?


To which event do you refer?

If you mean when the other line was connected, do you have a rough idea when that was?



Do you have any idea what might have caused any of yesterday's disturbances? (See the attached MDWS graph).

[GigabitEthernet]

No idea I am afraid.

It is weird though that it seems to sometimes affect the upstream and at other times, the downstream.

Perhaps this interference is the reason for my rather poor (IMO) upstream sync?

Engineer arriving on Monday between 8 and 1.

What should I be asking them?

[GigabitEthernet]

DLM has removed upstream interleaving for no apparent reason.

[Dray]

According to MDWS, G.INP is off completely

[GigabitEthernet]

It's very odd why DLM decided to remove interleaving when the upstream wasn't error-free but oh well.

SNRM is still going up and down like a yo-yo.

Which graphs should I be showing the engineer and what should I be asking for?

[GigabitEthernet]

A user on MDWS, craigv, seems to have a very similar looking line to mine:

Another thing I've noticed: my attenuation has gradually got bigger?

It's gone from 23dB up to 23.3dB in the last 20 days or so. Surely that's not right?

    I am still not sure that anything is amiss in your Hlog.  Looking at all the people with syncs of about 38Mb/s it seems normal for the upstream values to only be shown when an upstream tone achieves a bit loading.  You have just picked one such example. 

  It is also normal for attenuation to rise as the weather gets warmer and wire resistance increases, your increase could be just that.

  Has an engineer measured your lines AC balance and advised on how it compares to good/fault values.  I remain of the view that the fluctuations in snrm are to only clearly unusual feature of your stats.  That odd behavior may be a bad and changing noise background on a good line or more average noise aggravated by a line with poor AC balance. 

 If it just noise it is possible that an RF3 might help.  It will loose you about 1Mb/s but help IF the noise is common mode. Usually it is not common mode and it does not help but it is worth a try. If you have one or get one is it best to wire it up into a RJ11 cable so it trivial to insert and remove. ahead of the modem

My attenuation fluctuates from time to time, seems to be nothing to worry about. When my HR fault was repaired, Attenuation didn't change

[GigabitEthernet]

I'm getting conflicting views here.

Is my line faulty or not?

Hi Alec - see you're on Plusnet and ThinkBroadband as well...

I'd say there was a problem owing to the wild fluctuations in your SNRM, I don't think attenuation changing as per JIDs comment is much to worry about. Everything is supposed to change over time depending on the temperature, or at night when your line acts as a large radio antenna - your line is made of metal so resistance etc will change depending on various factors.

It just shouldn't change as wildly as yours does - that's indicative of a dodgy joint or some kind of electrical interference.

^ Thank you That is what I thought, I just wanted confirmation that I'm not going crazy!

Is the engineer likely to look at my graphs if he sees that they come from a "hacked" HG612?

From experience, some engineers will be keen to look some won't even realise you can hack the HG612.

The engineer I last had was great, he saw the MDWS graphs and said something looked wrong and off he went, however in the past I've had an OR engineer who didn't understand the graphs at all

All depends on the engineer you get
