Hi
I have had a resync in the early hours of the morning and my attainable has jumped from 49 to 61 and my snr has jumped from 7.9 to 16.1 but my down load has dropped a bit , I am banded at 43998 and on a 55 /10 line with idnet
Stats on MDWS same as username if some one would just have a quick check for me please
Thanks
Chris

I don't think you can tell on there,you have to look at the telnet output
-
What modem/router are you using?
Some report vectoring status.
-
Thanks
Using a Zyxel 9325 B10B
just checked and showing ( below ) i presume vectoring 1 full is vectoring applied , would it be worth asking idnet to try and get my banding lifted

Have you had a look in the GUI magement page?
-
thanks lee111s , i just edited my post above to show this , thanks
-
You do indeed have vectoring.
-
thanks
-
It's such a black art this VDSL. I have a lower attenuation but a considerably lower speed downstream and upstream. No G.INP or Vectoring, but presumably that's because I'm on an ECI cab at the end of some aluminium cable.
I know this adds nothing to the discussion, just thought I'd reiterate the 'them and us' thing ;)

I wish that vectoring had not been enabled, had a steady 43998 for months and now the DLM system has been playing and down now to 28780 with a 19.6snr , had a few restarts yesterday due to thunderstorms and the electric going on and off and just done a manual reboot now , will this pick up on its own
Cheers
-
You could use a modem that doesn't support vectoring
-
I contacted idnet to see about getting the banding lifted and after chatting and a few reboots of the router and cable swaps just to eliminate my equipment I now have an engineer booked for the morning to reset my line.
The support I have had from idnet has been amazing and I can honestly say that I have never had support like this from any of the other providers I have used

This surprises me. As I understood it an engineer can only reset DLM if he/she found a fault on their (Openreach's) side and that they can't just be booked to solely reset DLM. If that really happens then that's amazing customer service.
-
With the reboots and thunderstorms that caused the electrics to have a few outages my speed had halfed so this may have also helped getting the call out
-
The Openreach engineer has just left after been here for nearly 1.5 hours , checked all my line, no faults found , replaced the Mk 3 face plate with a new type that just clips in to place ,remade all the connections in the master socket and did a DLM reset by telephone using the secret menu ( only known to telecom engineers , so he told me )
the test equipment that he was using was showing my line was running at 6.9 snr with a download speed of 31490 and upload 6.5 snr and 7800
He connected the cable back to the router (Zyxel 9325 b10b) and once synced the router was showing connected at 55000 with an snr of 9.7 download and 9526 and snr of 6.5 down , the MDWS is showing that interleaving is applied and G.INP on the downstream only
Attainable is showing 62237 down, he was suprised that I was synced at 55000 for the length of my line ,so vectoring must be doing something and no errors apart from fec errors showing
Will see how it goes over the next 48 hours
Cheers

-
If he did a DLM reset there shouldn't be G.INP on the downstream. The default state for a Huawei cabinet after a reset is usually interleaving.
-
I asked him twice if he had done a full reset on the DLM and he replied yes , there is G.INP showing active on my MDWS , so I don't no what to think now
same name on there as username here
-
When I had a DLM reset G.inp was removed but came back on a couple of days later on downstream, before that I had G.inp on upstream but only briefly when there was fault on the line. Your speed seems to be much improved now so just see how it goes over the next few days. I don't suppose the engineer offered any explanation for why your speed was hit so hard by DLM just after vectoring was enabled. Thunderstorms are supposed to be treated as wide area events and not cause DLM action, but who knows how BT's systems work!
-
He had no explanation and also could not understand why his test equipment was showing different readings, he took a lot of notes and shots of my stats for before and after vectoring was applied and was going to pass it on to someone in his department, I will just monitor it now and hopefully it settles down again
Cheers
-
why was his test equipment syncing so low?
ahh I think his jdsu probably doesnt support vectoring.
-
You could use a modem that doesn't support vectoring
and annoy all those other vectored users as he would then crosstalk onto them ;)
-

That would imply that vectoring has pretty much doubled the attainable line rate, 31490 to an attainable of 62237 :o
Possibly the DSLAM backed off the power so not to affect other users???
-
Vectoring can double line rates on high grade copper, never mind whats on BTs network :)
-
Previous to vectoring on my line I was synced at 43998 which it had been at for a couple of months , I presume it was banded, it certainly lifted the attainable from 56000 to 61000 and some
Cheers
