Looks like upstream interleaving has been enabled but the SNRM has plummeted...

Looks like your stats have been down since around midday Alec?

Back online now - take another look

[GigabitEthernet]

SNRM is still stuck at 4dB...

   Hmm . . . There definitely is something wrong with your circuit.    The problem is being able to point a paw towards the defect. I think you are going to need considerable patience and maintain a close watch on the circuit's performance.

TalkTalk are refusing to raise a fault with Openreach because the circuit is supposedly operating at advertised speeds. However, as I have tried to point out to them, the issue is the significant noise ingress and poor AC balance of the line.

To that they replied:

Can you run at least 3 speed tests at different times of day on the following speed tester, with PC connected to router by Ethernet cable.
 
http://www.supportal-test.co.uk/
 
Can you also please run 3 sets of pings and 3 sets of trace routes to www.google.co.uk and can you post the results

Did they even read what I wrote?

Here are a couple of linked suggestions to contemplate --

• Terminate the contract with TT as unfit for purpose.
• Migrate the service to A&A and invite them to enjoy getting the circuit fixed.

On the phone with TalkTalk "technical" support.

Right I give up. An email is on its way to the CEO office.

Progress!

A fault has been raised with the Networks Team.

Glad to see that TalkTalk's Twitter team aren't useless. They're willing to add my graphs/data to the fault notes.

I'm not an expert on such things so would somebody suggest which graphs to send and a brief description of what is wrong in each?

[Bald_Eagle1]

I would suggest these:-

An ongoing FULL__MONTY montage for the last 6 days (plus possibly one for each day)

Snapshot montages from each resync

A copy of RESYNC.LOG with a manually added reason for each resync (if you know the reason)

An explanation for any gaps in the graphs.
Have you not been logging the stats 24/7?

It may also be worth including individual graphs from HG612 Modem Stats and/or MDWS for anything that needs particular focus (e.g. overall SNRM & SNRM per band).


I'm sure some of us would take a look and offer advice/suggestions if you were to post some/all of those in this thread.

[GigabitEthernet]

I've recently migrated to a new system so the logs are split up but attached is one full monty.

Any large gaps will be when the system was turned off.

[GigabitEthernet]

Snapshot graphs in order attached over the next few posts.

The last couple will be when TalkTalk asked me to do some tests in the test socket, a couple other may be when I was changing ADSL cables, etc.

To be honest, the connection has actually stayed up for quite long periods it just errors like crazy and the SNRM fluctuates a lot.

And more...
