Speed Tester / IP Profile Problems

Hi

My BT IP profile is 2500kbps
IP profile for your line is - 2500 kbps
DSL connection rate: 448 kbps(UP-STREAM) 3136 kbps(DOWN-STREAM)
Actual IP throughput achieved during the test was - 1298 kbps


PN MSR is 2500kbps

Your High-speed Broadband Service
Your current broadband speed is 2500 Kbps


Namesco Speedtester is 1500kbps
Download Speed: 1498 kbps (187.3 KB/sec transfer rate)
Upload Speed: 363 kbps (45.4 KB/sec transfer rate)
Download Speed: 1497 kbps (187.1 KB/sec transfer rate)
Upload Speed: 361 kbps (45.1 KB/sec transfer rate)


Exchange VP's are green

All speedtester results come back and say around 1488-1501kbps?

My guess is PN's MSR has is not correct... Can someone please look into this and confirm? Evil (James, where r u?)

Everything is set correctly at our end.

Interesting that your BT Speedtest comes back that low too. Were you connected on the BT Test Login at that time? Are these results at peak time?

Little odd tbh.

BT have you at ~2800kbps against our 2500kbps. Not sure why you are getting speed results that are practically identical constantly, with a slower speed than I would have expected.

Keep trying and see if it differs at all?

Thanks for the replies, results at varying times, peak and off peak...

Somethings not right? Is there anyway to actually break out of the PN network and route directly through BT? This would help pinpoint the issue...?

My ADSL is totally plagued...

Cheers James, thought that way had been discontinued by BT

The Results
The speed test has completed on test server speedtester1.nat.bt.com for user xxxxxxxx and you have downloaded a 1.7Mb file at a speed of

What do you think this result means? Shockedops:

Assuming your speeds are still similar on normal speedtests, it's suggesting that your speeds are slightly faster on BT's Network alone, than on ours.

Does gateway hopping help at all?

Hi James...

I'm on pte-ag1 (not sure what gateway before) and take a look...

Namesco Test:
Last Result:
Download Speed: 2356 kbps (294.5 KB/sec transfer rate)
Upload Speed: 356 kbps (44.5 KB/sec transfer rate)

Game on, looks sorted!!

James, you remember that we got BT to assign a manual SNR target of 12.5db?

Well not sure if you know but I made some filtering changes (direct into XTE-2005) and my sync instantly shot up from 1888kbps to 3136kbps, the only thing limiting this from going up further looks like the manual 12.5db SNR target...

Downstream Sync - 3136
SNR Margin - 12.5db
No drops at all

What do you think?

I think that BT don't like dropping SNR levels. :/

Did that ticket ever go anywhere? I remenber raising it shortly before I went on holiday.

James, How was the holiday?

BT did drop it to 12.5db which is where it is now...

What I'm asking is, what are the implications of this being set back to automatic?

Holiday was cold. Spent in Sheffield and Rotherham...

Implications? Potentially experiencing some intermittency. The biggest challenge would be to get BT to drop the level lower Smiley

In a pub no doubt? Dude, I just had the worst holiday ever!!

So can I clarify...

Is it true that usually, the line has automatic SNR targeting which is arrived at after the training period.

and

in the event of a manual SNR target being set, this disables the automatic targeting?

So what would happen if my line conditions were to improve drastically? Would the line adjust or would it be capped by the manual 12.5db SNR target instead of the usual automatic 6db?

If your line condition were to improve drastically, I would also expect the automated noise margin to decrease accordingly.

Hi James, that's exactly the question...

Now its been manually targeted at 12.5db and the line conditions have improved (but is still on 12.5db - coincidence?), is it automatic any more?
