BRAS figures correct
« on: March 18, 2017, 12:27:49 AM »

These are the downstream numbers today for my three lines

           Sync     BRAS        AA Tx rate
Line1   2827k   2493k   2460621
Line3   2880k   2261k   2506899
Line4   2934k   2305k   2554051
         
Totals   8641k   7059k   7521571

What's going on with the BRAS numbers for lines 3 and 4? BT say they have outstanding faults being worked on.

I wonder if anyone else has had odd BRAS values that don't match the sync figure?

I emailed my ISP about it. I worked out that I'm losing about 460 kbps downstream currently because of this.

you on 20CN adsl or 21CN?

20CN adsl BRAS system takes up to 5 days to increase after a sync speed increase, I think BT never really fixed the slowness on 20CN.

The Broadford exchange, at which all of Weaver's circuits are terminated, is 21CN.

With 21CN the rate changes seem far better generally, although I am not sure what the rules are.

Interesting reply from AA:
  • “Thanks for your email, the BRAS rates only apply on 20CN circuits, you have 21CN and the full sync rate is passed to us by BTOR irrespective of what shows on control.aa.net.uk.”

So shows you what I know, thanks to AA for that. If I had realised at the time, you can read off individual data rate points from the CQM graphs in clueless.aa.net.uk by simply clicking on a particular time. That would tell me what the real traffic was.
