Maximum acceptable sync loss


[link to this post]
 
Hello dudes,

So the installation of my second line seems to have played hell with the primary. From initially having a max attainable back in 2013 of over 98Mb it settled at 64-67Mb up until this week when the second line into the property was brought back into service.

It's now banded at 55Mb, and errors continue to merrily increment even at that level, stats below.

So it's lost over 18% of sync and had at least 3 DLM interventions, the last of which was banding. I don't know the exact details of that as I don't monitor obsessively.

It's not yet outside the 'clean' estimate range, which goes down to 54.3Mb. Would my provider be able to raise a case with Openreach?

Max: Upstream rate = 20132 Kbps, Downstream rate = 64916 Kbps
Bearer: 0, Upstream rate = 20000 Kbps, Downstream rate = 54999 Kbps
Bearer: 1, Upstream rate = 0 Kbps, Downstream rate = 0 Kbps

Down Up

Do you a landline phone? Dial 17070 and select option 2, the line should be quiet.

Router in use: Billion BiPAC 8800AXL.

It's not a WLR line.

what's the upper end of your clean range estimate? 80mbps?

I assume if you disconnect the new line the error's plummet on the first line?

I got no idea what openreach would do, they now have added a new figure on the BT wholesale checker which is below the 20 percentile used for the clean low range, and kitz's isp are using that to stop her fault been escalated. If your isp (or openreach) does the same then you may hit the same brick wall. It seems in return for openreach and CPs offering to refund people for low performance the goal posts for determining if a line is under performing have been moved.

I would probably raise a fault and see what happens. There is ways to alleviate the threat of fee's.

73.4. The range is 54.3-73.4.

Between distance from cabinet and worst case scenario crosstalk 80Mb is impossible without vectoring smile

Doh.

http://www.speedtest.net/result/3219692669.png should be the first one.
