Plusnet Current Line speed and BT IP Profile (FTTC)

<Moan On>

Just a comment on Plusnet's tracking of the BT IP Profile on FTTC...

Why does it track downward trends so avidly but ignores increases in the BT IP Profile...

I know Plusnet can reset it, and they have twice before, but still..

Well it shouldn't ignore it, mine has tracked it upwards a couple of times recently.

I have no problems running the BTW diagnostics and I copied the information from that onto the Plusnet ticket (86597571)

Without being able to do that I'd have to do the maths from my sync speed, which I guess is what you're having to do.

I've got an HG612 back on the line so that I can track these changes in sync speed and see when they're happening. I'm glad that I'm not the only one who's Plusnet speed doesn't match the BT IP Profile.

We shouldn't be setting you at 78000 as the highest profile you've reached is below this, setting it too high means our traffic management isn't as effective for your line.

Your line is syncing at 77460 and has a profile of 74900 (74800 on our side). This is correct as the profile is 96.7% of your sync.

Pete's speed *does* match the sync and profile correctly. I'm taking a look at yours now.

Yours is a bit odd, we've not received a line report for your line for quite a while, hence it not changing. I've manually set the profile now to 96.7% of your sync rate.

Sync= 74.4 Mb/s
Profile= 72 Mb/s

Ive NEVER been able to see the BT profile data for my line, always gives an error.

The PN supplied router was continually crashing and was causing disconnects (not line drops) so this was muddying things a little.

I now have a new router that is not rebooting every few hours so stable line, yet I still cant see my profile data!

Im on the Samknows panel and the latest tests are approx 65Mb/15Mb, and according to the portal I should have 78/20.

Why cant I see the BT data? Without this I cant know what my line is synced at????

Thanks Chris for sorting out my profile issue. It seems that it's not as common an issue as I thought!

Every time I've had an issue with Plusnet they've always resolved it for me or explained why they can't do what I want.

Thanks Plusnet or more accurately the Plusnet Digital Care team.

There's a problem we're aware of that means some customers can't run the test to get the IP profile, we've been talking to BT Wholesale about it and will continue to do so until it's resolved.

Been 3 months now, any progress at all???

Can you see the sync?

I have raised this matter back in February with Chris Pettitt....and it now June. That's four months now and I was really surprise that BT Wholesale doesn't care to do something about it. But, mine is fine and was fixed by Chris Pettitt here: http://community.plus.net/forum/index.php/topic,1242...

I'm still working on this. Had a call with BT Wholesale yesterday afternoon. They think they know what's causing the issue but I'm yet to get details on what they think is the problem.

I should hear more on this over the next couple of days.

::edit:: and now he's left.. with the cover for the box on the pole dangling so it's exposed which means we get some rain....

Idiot.

From the BT website:

Damage to outdoor equipment like junction boxes, telephone poles and overhead wires

This equipment is looked after by Openreach, and you can report the fault directly to them.

You can report the problem through their website or over the phone on 0800 023 2023

The Plusnet profile just set itself down on my line again... only a tiny bit to 71.8 Mb.

I've been collecting stats from my HG612 and it doesn't show any line re-syncs during the 4 day and 11 hour period, though there have been connection resets, and is still synced at 74444 kbps

I don't understand why it's below the BT IP profile of 72.06 as I thought they were meant to be identical.

@timl if BTW profile is 72.06Mb and your PN profile should be 72.0Mb

In reply to a post by adslmax:

@timl if BTW profile is 72.06Mb and your PN profile should be 72.0Mb

Indeed, and it isn't, so the question is, "why not?"

I would want to see the current IP Profile before passing judgement. Not a statement of unchanged sync.

timl did say the IP profile was 72.06Mb, which matches the sync, so unless it briefly sync'd lower and the IP profile followed it down, then it all went back up again, the Plusnet profile doesn't make sense.

Exactly, it doesn't make sense. So I don't trust figures that are not supported by a test taken and copied at the time, and also in this case a view of the full HG612 xdslcmd info --stats figures.

Hi Roberto,

Here's the results from the xdslcmd. I think there's a clue to the Plusnet sync... it seems to be taking the attainable or sync rate whichever is lower.

When it was first put in the attainable was in the high 90's. Now, whatever it syncs at the attainable is either exactly the sync or slightly below it... it varies throughout the day (as my sync log shows)

If it were (which it isn't), that would give 71.5 or 71.6, not 71.8. You will probably find that the attainable figure varies from one minute to the next in any case.

Yes I was making an assumption and I shouldn't have.

And here are the BT and Plusnet portals with current rates

BT SpeedTest

Plusnet Page

It is a bit odd, but it will be having a negligible effect on your speeds. But you are right, it should be 72.0, not 71.8, I'm sure Plusnet would nudge it up if asked.

I've asked Plusnet to nudge it up for me last week... and I raised a fault ticket for it when it went down to 71.8.

I just want to understand why when Plusnets system tracks BT's profile they appear to show different values.

Very strange. I've no idea how that happened.

It should track, as you say, but the "Max" figure I don't think matters. The tracking isn't exact by the way, it is to the 100kbps below the BT IP Profile, and I thought was set from that not from the raw sync.

I had the following reply from Plusnet (slightly abbreviated).

If I'm understanding correctly they're saying that it should have tracked the BT profile but it might not be the same as the BT profile... this week it was only 0.25Mb/s, but last week it was 4Mb/s out! I know it's not a lot and I should just be grateful for the service I get... but if I was with Zen or BT I wouldn't have this system getting in the way! So perhaps I need to consider whether it's worth moving for an extra 4Mb/s

Thank you for getting in touch.

Due to the way profiling works you may find that our profiles occasionally are not perfectly reflective of the BT profiles. The BT profile will be quantized whenever a resync event occurs, whereas our profiles will only change when a 'delta report' to be generated. These delta reports are submitted to our systems by the BT line management software, and unless one is received the speeds don't update. They are not generated constantly, and there can be some time between reports- particularly when there are no significant changes to your speeds.

The receipt of a delta report and subsequent change of profiled speed frequently forces a disconnection as well. If your line changed its speed as regularly as the profile was quantized on BT systems not only would it have a massive negative impact on our resources and ability to manage accounts, it would also cause additional service disconnections.

In this instance because the difference between our profiles and the BT profile was so small it did not trigger a change

You should ask someone on plusnet community forum to ask plusnet staff to put your ip profile on 72.0 to match BT IP.

Hi Adslmax,

Thanks for the excellent advice. Plusnet raised the profile to 72Mb soon after my last post. I did a speedtest which is the most stable speedtest I've had for about 6 months.

Glad to hear it.

Mine seems to have fixed on its current value without much change.
"Download speed achieved during the test was - 58.99 Mbps
For your connection, the acceptable range of speedsis 40 Mbps-69.89 Mbps .
Additional Information:
IP Profile for your line is - 69.89 Mbps"
My Plusnet info:
Estimated line speed:
There's no speed estimate currently held on your account.
Current line speed:
69.8 Mb"
.
Should it be higher?

In reply to a post by jackburt0n:

No, assuming you mean the Plusnet line speed. If you are talking about the download speed then yes, you should be able to do better, try the test on this site and see what that comes up with.

Yep, sorry meant download speed.
Test taken today on this site
58.16 Mbps
This pretty much reflects the consistency of my regular speed. I note TB speedtests used to be around 64 Mbps up until around August last year when it dipped to its current level.
More curious than anything as the extra speed is not that big a deal.

Edited by jackburt0n (Wed 11-Jun-14 19:40:57)

How about speedtest.net, any different?

Seems pretty consistent across them all.
http://www.speedtest.net/result/3557509438.png

That is odd but I'm going to ask the daft question - you're not testing using a wireless connection, are you?

Using ethernet all the way.
Well, at least it's consistent. Looked back at all my TB speedtests back to May last year and 66.58 Mbps was the highest but as I said they settled to their current level about end August last year.

66.58 would be about right, I wonder why you're losing that extra 8Mbps or so. It might be worth raising a fault for that.

If it were to decline I probably would, but twas more curiosity than anything as I recall it being faster. As it's quite consistent and fairly stable I don't mind, but thanks for your input and help.

Your IP Profile is 68 Mbps but your downstream throughput is 58 Mbps (that's is 10 Meg big gap) your throughput speed should be around between 64-66Meg.
