SNR and Interleaving

[#1]

Hi Alex,
They were performed over ethernet.The speed seems to be jumping around a lot. One minute it's at 2Mb, then 6Mb, then 2Mb then 4Mb. I don't really know what's going on? It started when Adam increased my profile at PlusNet's side.

[#2]

There's no technical reason why this is happening.  It could just be a temporary capacity issue at your exchange.  Please monitor your speeds over the course of today and let us know if the problem continues.

Hi Alex,
The throughout is back to normal at the moment. Let's hope it stays that way!

[#4]

Well, it was fun whilst it lasted...
ADSL Link Downstream Upstream
Connection Speed 3776 kbps 448 kbps
Line Attenuation 43.0 db 24.0 db
Noise Margin 14.6 db 23.0 db
On the plus side, the throughput is normal.

Restarted this morning, not much better.
ADSL Link             Downstream Upstream
Connection Speed  4000 kbps 448 kbps
Line Attenuation     43.0 db         24.0 db
Noise Margin     15.8 db         23.0 db

All ok now!

[#7]

I raised a ticket and support said they would reset my SNR. Nothing has happened. Could this be looked at?

Hi sjrinfroyle,
We're exceptionally busy on the digital care team today so I'll need to ask for your patience here. Someone in the CSC will reply to your ticket eventually.
Thanks.

[#9]

Sorry about that Adam, I didn't mean to sound desperate. I'll wait!

[#10]

I have got a response. I was originally told it would take 10 minutes, now I am being told it will take up to 72 hours? I don't need anybody to check this, I would just like a definitive answer on how long it should take.
Thanks.

[#11]

In a way both are correct, the reset itself takes a few minutes but it can then take a further 72 hours for the IP profile to increase.

[#12]

Ok, but my SNR doesn't seem to have decreased at all:
Stats:
                        Down            Up
SNR (dB):        14.6            23.0
Attn(dB):          49.0            22.0
Pwr(dBm):        19.6            11.9

[#13]

It's now been over 24 hours. I understand that it takes three days for the speed to increase, but the SNR doesn't seem to have reset, so there will be no speed increase as the speed hasn't changed.

[#14]

I'll have to get back to you on this sjrinfroyle as I need to look at the bigger picture. Please bear with me and I'll get back to you this afternoon.

Thanks Adam,
As always, thanks for responding so quickly and helping me with my problems.
