What is strange is my upload has gone from 5Mb to 8Mb something the engineer who came when the upload dropped from 10Mb to 5Mb couldn't get back despite putting me on a new pair and a reset, now all of a sudden I gain some back and loose a chunk of the download in the process. not happy
Download speedachieved during the test was - 46.66 Mbps
For your connection, the acceptable range of speedsis 40 Mbps-48.15 Mbps .
Additional Information:
IP Profile for your line is - 48.15 Mbps

Your speeds are quite like mine. Best download from TTB was 66.61 (14/06/2015), best upload 18.46 220/07/2014.
Nowadays, I'm luck to get 58 down, 18 up.
But for a day or two, the following is typical
11.44 Mbps (single thread) 52.16 Mbps (*6) 15.75Mbps(up)
I could be wrong, but there seems to be grotesque congestion somewhere.
Of course, no announcement/posting/warning from Plusnet. No graphs to look
at to verify it's not just me. Only wiggly TTB graphs on a speedtest (and the
problems could of course somewhere nearer or in TTB. Bah!

this is how it is now
Download speedachieved during the test was - 47.29 Mbps
For your connection, the acceptable range of speedsis 40 Mbps-49.04 Mbps .
Additional Information:
IP Profile for your line is - 49.04 Mbps
Upload speed achieved during the test was - 8.58Mbps
Additional Information:
Upstream Rate IP profile on your line is - 20 Mbps
what's going on it's been 55.9Mb down 5Mb up for nearly year after the last engineer visit and all of a sudden this, what i don't understand is why the upload has suddenly gained back on the expense of the download where had it gone could something in the cab be faulty or something i dunno and what caused the drop in the first place it wasn't DLM because the profile is fully open Interleaving would have been applied if the line was unstable so something caused the drop and at 3 in the morning it certainly wasn't me.
i'm still above estimate for anything further to be done ? can someone from CRT confirm that. so looks like i'm stuck with this not happy at all

How do you know - have you attached your own test equipment and analysed the waveform :P? I would be a little surprised if crosstalk required the DLM to intervene twice in one week as I assume interference is fairly constant(*) but maybe someone else has just been connected and crosstalk has worsened again. Is yours a relatively new cabinet? If it's been there a while then two new users in the space of a week seems unlikely but if it's only been active for a month or so it's more likely.
Quote from: Terranova667 this is not cross talk
Ultimately crosstalk isn't a fixed 'thing'. Some people never get affected by it. Others get affected by multiple users over time. You could go years without noticing a problem then suddenly a neighbour signs up and wham! you've been hit.
Sadly I suspect that until/unless your downstream speeds drop below 40Mb/s BT won't want to look at it. I don't think they take upstream into account.
(*)By 'constant' here I mean for a particular cabinet configuration. If/when a subscriber leaves or joins crosstalk can change.

Sync Status In Sync
Downstream Speed 50.1 Mbps
Upstream Speed 4.7 Mbps
Appointment Required N
Fault Report Advised N
Profile Name 0.128M-80M Downstream, Error Protection Off - 0.128M-20M Upstream, Error Protection Off
The upload speed is below where I'd expect, the fault is with the team here to look in to so hopefully they'll be able to help out.
