Sounds like they will simply cap your downstream sync by sticking the SNRM at 12dB or something like that frown

They really are a complete waste of space...if they are aware of the issues then a SFI should be booked!

Funnily enough, I did say something very similar to them regarding how they will deal with this fault. I don't think they have any intentions of actuall investigating the root cause of the fault, but as I said before, they will just paint over it. It's sad, but that's the stage they're at.

I may be wrong with this next bit?

I mentioned to the Fault Manager that If my line can not support the speed and is stable at 4.5meg, when Fibre Optic is available from FTTC, would I be able to receive the quoted figures? He said "it would hold 30 to 60 meg just fine.) considering its the same copper cable as now, is that not some sort of a contradiction ? As I said, I may be wrong, but it seems slightly odd.

Only as far as your local cab. The fibre replaces the copper cable from cab to exchange.

So, they are probably right. The BTw Availability Checker with give the best estimate for FTTC.

Oh dear frown I'm getting the feeling that I'm a long way from being out of the woods yet?

I'm guessing they will do what 4M2 suggested? NM up to 12db and hope it stabilises my line enough to stop me moaning.

Is it worth me mentioning the confusion they (EE) are having with Near and Far End?

With FTTC, I'm guessing the technology is different and that's how the higher speeds can be achieved.
Although our exchange is "fibre ready" our street cabinet has not been upgraded - and OR think its not "commercially viable to upgrade it yet" so it's onwards and (hopefully) upwards with EE for now.
I may even get a direct line to the Fault Team soon smile

What I should of said is, although the existing copper wire from cabinet to my home would be shorter, would that mean it can cope with the higher FIbre speeds ?

Let's hope they do nothing for the time being other than perhaps switch you to interleaved, which might happen automatically anyway.

The fact that there may be problems with the copper pair between your NTE5 and the cabinet means they are talking absolute nonsense when they mentioned potential FTTC speeds on your current line.

Err - no.

The copper wire from the cabinet to your home is unchanged. The wire from the cabinet to the exchange then only carries your voice traffic and is filtered at the FTTC cabinet. You do have a slight increase in the cabinet to home length as the signal effectively has to travel from the FTTC cabinet to the PCP to connect to the home copper. More detail.

4M2.... It looks like you we're spot on with the NM!

They've stuck you on ADSL1.

Does it work if you set ADSL Mode = ADSL2+ and then reboot?

I'm out again right now, but will give that a try when I get back smile

I hadn't even noticed that they seitched me from ADSL2 + to be honest.
Is there much difference between the two - as Errors seem to of stabilised and they are sending out another Router now. Also I still have a ping of 100ms (min) 204ms (max) so I'm unsure If there may still be an issue somewhere.

Just got in and noticed that the router was re-syncing. Checked the stats and its now on ADSL2+ and moved from Fast Path to Interleaved.

I'm guess I'm no in re-train ?

Here are the stats.

The difference between the downstream ADSL1 and ADSL2+ attenuations of 3dB looks fine, interleaving doesn't seem to have helped the error rates on ADSL2+ just yet...

Probably a good idea to start a new thread when you hook up the replacement router in the test socket smile
