Title: Crosstalk has caught up with me
Post by: roseway on December 11, 2014, 07:09:15 PM
My FTTC service was enabled on the 25th September. At that time my max attainable DS speed was 92917 kbps. Over those ten weeks or so the max attainable DS has steadily come down, and today it reached the point where the max attainable DS equals the actual DS speed (79987 kbps). :(

I guess I've joined the club.

Your DS SNRM has lost say 2dB over thoses 10 weeks and you are now sitting on the 6dB FTTC target margin.

You still have a good line it will be interesting to see what vectoring does to your line when it's been made active on your cabinet  :-\

*pokes BT with a pointy stick*

Hurry up and roll out vectoring.

I look forward to it. :)

As with all anticipation these days it may fall short on our expectation  :(

Aw, NS ......... Christmas is just around the corner my friend, let's try and be upbeat and not condemn something that has been years in the making.
I think we'll hopefully see roll-out sometime in Feb 2015, but this is just my own opinion from the limited info I've read.

Chin up mate.  ;D

Looks like I took another small hit this week too, bringing my headline loss to 30Mb. 

I gained some back by using the Zyxel rather than the HG612, but Im now at the stage where if I put any other modem/router on, I wouldnt get 80/20. 

Cheers BS any info is always appreciated :)

  On the bright side of things   :)  your error rates look fine and are I think more important than exact speeds provided the speed is pretty good.  Higher errors would give the interleaving speed drop and latency increase.   Without of a speed test, I concluded that I simply could not tell the difference between 60 and 80Mb/s. I did think that I could tell when I was interleaved, though even then it hardly mattered. I am not sue what you would have to do to really notice?

Do you see a blanket rollout or just targeting popular cabinets?

*joins in*  ;D

I was under the impression new hardware had to be installed in the cabs for vectoring? Or is it such a simple task BT could roll it out pretty quickly? IE tell the next engineer who has a job at that PCP to connect up this new bit of kit (I know it's not gonna be anywhere near that simple  :D )

I thought I heard somewhere that installing the necessary hardware typically takes around 30 minutes, but that could be for something else in the cabinet so I might be wrong there. If I'm correct, downtime should be minimal and there's a small possibility that the downtime might be further reduced by a method of putting the new hardware in, switching the ports over, then shutting down the old hardware and removing it (if that's even possible).

Yep, something hotswappable any engineer could do on their next visit to the cab would be brilliant  ;D

I think I also got some new crosstalk, I thought was neighbour's central heating left on 24/7 but someone came today to turn it off (Was left on with noone there, made a racket all night), and attainable didnt go up :(
