Well line/fibre done but there are issues!!

The line seems to be provisioned on the 40/2 product as max speedtest I get is 37.5/1.95 - not a big issue as it's probably not updated Plusnet's end yet.

What is a problem is when I pickup the phone, there is a beeping sound which seems to last a few seconds and a constant clicking sound - obviously a fault.

When the Engineer rang this morning, he said he's detected a fault between exchange and my house which he obviously hasn't remedied so I think I best ring Plusnet and report this. I wish I'd been there when he was installing the line as I would have picked that up straight away.

Any thoughts anyone?

Are Plusnet your voice provider? If so call them, if not then call the appropriate provider.


As it is not an FTTC issue he may not have been able to fix it especially if it is in the exchange. However, he may have reported it.

Well I've managed to sort the problem myself. I had to reboot the modem as Plusnet told me I needed to but I decided to swap th eopenreach modem/router combo to my Billion 8800nl so I can see the stats. Soon as I did that, the noise disappeared! Strange but true.

Can anyone run their eyes over these stats and tell me what they think?


Downstream Upstream
Line Coding (Trellis) On On
SNR Margin (dB) 18.5 20.0
Attenuation (dB) 19.5 0.0
Output Power (dBm) 12.4 4.0
Attainable Rate (Kbps) 84485 16190
Rate (Kbps) 39998 1999

Obviously I'm still waiting for Plusnet to change the profile after they provisioned me on the fibre unlimited instead of fibre unlimited extra but looking good to me for pretty good speeds once it's done

Ummm.

My attenuation is 19.8dB and I get around 58Mbps sync on a quite clean line from the cabinet. You'd think looking at your stats you would be at or close to 80Mbps but I don't think Attainable works at all like intuition and ADSLx would suggest.

Viz. the several Mbps gain in it when interleaving is put on FTTC , accompanied by a 10Mbps loss of sync, but the opposite when the interleaving is removed.

I do have a tiny amount of residual interleaving, (8/1), with G.INP active, so maybe that has an effect. On the other hand I was on a seemingly banded 60Mbps when upstream G.INP was also on. Strangely, having sync'ed a few times since that was removed, attainable is now always below actual.

The delay setting is zero.

Upstream Attainable rate looks a little low ... I would normally expect to see a full 20000 when te downstream is over 80000. Distance based attenuation will hit the downstream first and to will often see a downstream in the 60s with a full 20 up.


Wait until the profile is sorted and then a reboot to see what happens.

looks like the SNR margin is currently at 20db for upstream... probably due to small requirement for upstream (1999) so assuming that will decrease as demand for bandwidth comes.

In reply to a post by MHC:

Upstream Attainable rate looks a little low ...

It ties in with my actual on a very similar downstream attenuation. I believe it's the downstream Attainable that is wrong.

Not good after a restart, have started a new thread here.
