Upload speed noise margin

Hi
My upload noise margin is stuck at 16
Type Interleave Path
  Status SHOWTIME
                        Downstream   Upstream
  Data rate(Kbps)     22660               864
  Noise Margin         6               16
  Output power(dBm) 12               19
  Attenuation(dB)         11                 7

Any chance it could be bought back down to 6.
Thanks.

Hi towerblocks,
I can't do any testing at the moment/make changes at the moment, but I've made a note on your account so that I can pick this up later today for you.

Re: Upload speed noise margin

Hi again,
I've done some further checks on the line for you. We can ask that the SNR on the upstream is lowered, but can I ask what you are trying to achieve from this? You shouldn't see any difference to the upstream even with the lower SNR.
Thanks,
Tony

Re: Upload speed noise margin

Is the upstream speed restricted to 888k because interleaving is on? Why is interleaving on for such a short line as this?

Re: Upload speed noise margin

I should be getting the full 1.3Mb/s upload, Also having a higher noise margin on upload restricts download speed.

Thanks for getting back to us.
I've made the change on BT's side which is showing as successful. Please let us know if you don't see an improvement.

Hi
I've just rebooted the router, To make sure.
Downstream Upstream
  Data rate(Kbps) 22440 864
  Noise Margin 6 16
  Output power(dBm) 12 19
  Attenuation(dB) 12 7
Still the same.

Re: Upload speed noise margin

I suspect ejs's reasoning is the case. Upstream Interleaving needs to be turned off.

HI towerblocks,
I've tweaked some line settings a little further for you. Unfortunately this won't go through while Monday but we hope you seen an improvement.

Re: Upload speed noise margin

Hi,
I've raised a ticket on your account to monitor this because it isn't as straight forward as I first expected. An order was placed to remove interleaving for you which should have helped. I expected this to go through this morning, but it's now due for tomorrow.
