How Has Crosstalk Affected You?


[link to this post]
 
Given Openreach are hopefully, at some point rolling out vectoring I thought it'd be interesting to see how people are being affected by crosstalk.

Also might help give some indication of the kind of loss people who aren't hitting full rate can expect. I can imagine BDUK enabling a fair amount of longer lines.

Here's Mine:

Only one on cabinet.

150+ lines down.

I have had FTTC for nearly three years and have had no noticeable effect from crosstalk. Apart from the almost inevitable drop in the first few days (for those not very near to a cabinet), my speed has been constant with a sync of just under 70/20 for the whole time, other than a brief period when there was a fault. I have no evidence of what the FTTC take-up has been in the area; I know I was one of the early ones, but I am in a village that previously could only get poor ADSL speeds due to the distance from the exchange in the nearby town. I am roughly 450m from the cabinet.

I will keep it short and sweet to avoid a rant.

2 weeks after I signed up when I unlocked my modem I had 110 max down and 36 max up. (dont know if it was higher before that).
3 weeks after signup I had max 90 down and 36 up.
4 weeks after signup I had max 73 down and approx 29 up.

Since then it has slowly been going down but no more large jumps.
Currently at 66 down and 27 up. I have lost around 40% of the downstream signal, as far as I am aware I was the first on my cabinet.

Currently I sync 6mbit below my new estimate which ironically is higher than my original estimate.

My home is approximately 800m line length from the cabinet; physically 200m from the cabinet but the duct goes along an adjacent road before going into my road and all the way back to my house; so I am the second-to-last house connected. I guess this means I will suffer more from crosstalk than anyone else in the road.

My sync started-off at around 50Mbps, in the past six months it slowly reduced down to 34Mbps. I am hoping that vectoring will increase it to at least 40Mbps.

Distance from cab - 320 metres according to Google Earth.

My initial connection in May 2012 was 79999 down, 20000 up with attainables of 92000 and 36000.

I don't have access to my modem any longer but I'm seeing throughput of 67/18.5.

The recent firmware upgrade gave me a 10% boost on downstream and allowed for the removal of interleaving.

FYI, you can get your line's current IP profile (approx. 97% of sync) from this site:

http://windows.mouselike.org/be/index.asp?DoAction=B...

It's quicker and easier than using a BT Wholesale speedtest, and you can check it remotely.

The current Upstream BRAS rate is: 20 Mbps

That doesn't work for me, and I don't think it has for some time:

Looks like BT refused to test, possibly because a speed test or BRAS check has been run recently which prevents this tool from working. Try again in a few hours.
Debug: BT no BRAS info

Does anyone know if any information about the vectoring trials have been released? I thought they had finished.

it just runs the BT Wholesale speedtest, which can be run remotely anyway smile
