ADSL2+ Upgrade


[link to this post]
 
My exchange is due to be upgraded to 21CN soon, I just ran the ADSL checker and it comes up with this:

Our test also indicates that your line should be able to have an ADSL2+ broadband service that provides a fixed line speed up to 2Mbps.

Your exchange is planned to have ADSL2+ by 31st March 2013. Our test also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 14Mbps; typically the line speed would range between 8Mbps and 18.5Mbps. Our test also indicates that your line could support an estimated ADSL 2+ Annex-M broadband upstream line speed of 1Mbps and downstream line speed of 14Mbps; typically the downstream speed would range between 8Mbps and 18.5Mbps.


Does that ADSL2+ fixed line speed of 2Mbps bit mean that they are in the process of upgrading now? I'm fairly sure it wasn't there before.

the fixed line speed refers to the fixed speed products, of which 2M is the fastest. So the first bit means little. The wording gets changed a lot, by Indians by the look of some of the syntax, so I suspect it's a booboo if the upgrade is next year.

To add to what Yarwell said

yes it looks like WBC ADSL2+ is coming to your area, but the expected date is a few months away. So you will not see any changes for a long time, as it is totally different hardware in the exchange and backhaul.

The move from old IPStream to new WBC using ADSL2+ is not automatic at the wholesale level.

So when it says that ADSL2+ is available on the checker I will need to contact my ISP (Plusnet) and they will upgrade me?

Yeap though with Plusnet you can pay for a quick upgrade or wait for them to do all their users on that exchange in a batch which usually does not cost.

There's no cost for the upgrade, just let us know when your exchange is enabled and we'll place the order.

Thanks for your comments everyone.

I just ran the BT checker with my other phone line (the one which I currently have my connection on) and that produces a drastically different speed estimate of 6mbps down. Can it be that there would be such a large variation between two phone lines to the same address? Or perhaps it is because I have an existing connection on that number and they have more detail about the line quality?

Now you are asking a totally different question!

In reply to a post by Herstmonceux:
[semi-jokey bit]I just ran the BT checker with my other phone line (the one which I currently have my connection on) and that produces a drastically different speed estimate of 6mbps down. Can it be that there would be such a large variation between two phone lines to the same address?
Yes. It can be so.
Or perhaps it is because I have an existing connection on that number and they have more detail about the line quality?
Yes. It perhaps is.

In other words, there is only one way to find out, suck it and see.
[/semi-jokey bit]

The above is true. However what we need now is the line stats from your router. See here for help.

It is unusual for two lines at the same property to be very different in their speeds. How long has the phone-only line been in? If only a few days then check its estimate again in another two or three days as it could be showing the data for wherever it terminated the last time it was in use.

If it has been in a fair while, it could be that your existing line is under-performing. The stats will tell us if this is the case, and there are several things that can be done that stand a good chance of fixing it.

Yes, I have the same situation.
In reply to a post by Herstmonceux:

Partly! It's because you have an existing BTw connection on it.

I have 2 lines both actually capable of at least 16 Meg. My BB line has been on Orange/BT for over a year, running at 19/20 Meg but BT estimate it at only 13 Meg. What worries me is that if my speed ever drops towards the estimate, Orange will claim that I am still getting what I should and not fix it. My other line has only been on O2 LLU BB for 1 month years ago, running at 15/16 Meg but BT estimate it at the ridiculously low 7.5 Meg.

It looks like your 2 lines are estimated the other way round. What are you actually sync'ing on the estimated 6 Meg BB line?

1999: Freeserve 48K Dial-Up => 2005: Wanadoo 1 Meg BB => 2007: Orange 2 Meg BB => 2008: Orange 8 Meg LLU => 2010: Orange 16 Meg LLU => 2011: Orange 19 Meg WBC

Ummm!

As has been discussed, it could be the estimate for the ADSL line is low due to more information being available. But importantly that line is seriously under-performing and this could be affecting the information used for the estimate.

The correct estimate for that line is over 17Mbps, which tallies with your other one. However, that being the case, at your "capped" 8128Kbps, which is the maximum available on a "BT" ADSL line, your noise margin should be sky-high. See "Cause 3" on this page, then calculate back using
On ADSL such as ADSL Max each rise of 3dB in the target value costs between 500kbps and 750kbps of connection speed.
I reckon your downstream noise margin should be over 24dB.

Have a read about the Ring/Bell wire and Miscellaneous nasties in this section.

I'm assuming absolutely everything that connects to your phone line has a working filter, including Sky boxes and burglar alarms.

While line may be under performing and no harm in tidying up ring wire. I'd not be so pessimistic on the line, my usual power backoff comment does not seem to apply as power levels look high, but could just be the way that modem works when synced at the maximum rated speed

I sort of agree. I don't think it will be primarily the ring wire causing the issue, more likely one of the things I cover in the references I gave him.

I ran my number through the checker again today and it came up with the following, does this mean ADSL2+ is now available?

Exchange HERSTMONCEUX

Your exchange is ADSL enabled, and our initial test on your line indicates that your line should be able to have an ADSL broadband service that provides a fixed line speed up to 2Mbps.

Our test also indicates that your line currently supports an estimated ADSL Max broadband line speed of 7.5Mbps; typically the line speed would range between 6.5Mbps and 8Mbps.

Our test also indicates that your line should be able to have an ADSL2+ broadband service that provides a fixed line speed up to 2Mbps.

Our test also indicates that your line currently supports an estimated ADSL2+ broadband line speed of 14Mbps; typically the line speed would range between 8Mbps and 18.5Mbps. Our test also indicates that your line could support an estimated ADSL 2+ Annex-M broadband upstream line speed of 1Mbps and downstream line speed of 14Mbps; typically the downstream speed would range between 8Mbps and 18.5Mbps.

Finally got my upgrade today, here's my line stats:

DSL Status Up
DSL Modulation Mode G992_5_A (ADSL2+)
DSL Path Mode Interleave
Downstream Rate 17086 kbps
Upstream Rate 440 kbps
Downstream Margin 5.2 dB

Upstream Line Attenuation 8.3 dB
Downstream Transmit Power 20.1 dB

Speed test is still showing my old speed of 6.4 down and 0.4 up but I understand it takes a week or so before I get full speed. Is that correct?

your upstream speed seems to be capped.

Check what speedtester.bt.com says your IP profile is for downstream

I've run the BT speed test and here's the results:

Download speedachieved during the test was - 13.87 Mbps
For your connection, the acceptable range of speeds is 4 Mbps-21 Mbps.
IP Profile for your line is - 14.89 Mbps

Upload speed achieved during the test was - 0.2Mbps
Additional Information:
Upstream Rate IP profile on your line is - 0.45 Mbps


And here's a speedtest.net result http://www.speedtest.net/result/2421115552.png

So it seems that download has improved but upload is no better (actually worse) than before.

That seems to imply you're on a capped upstream profile. I'd query this with your ISP - your line should be capable of a faster upstream speed.

Re the capped upstream, that was supposed to be fixed not long ago. It clearly isn't.

Your quickest solution may be to post in the Community Forum and ask for it to be uncapped. (You'll probably see a few similar posts there.

Alternatively PM ChrisParr who posted earlier in this thread. He can do it. A PM might alert him, which is quicker than waiting for him or similar to see your speed here.

Is that testing speed on wireless, rather than wired? The downstream connection speed is comparable - though a daytime re-sync may restore that.

When worried about speed tests, always run wired. If the first time after a reconnection/re-sync, always include the text results boxes from a BT speed test as those show the IP Profiles, (in particular the downstream one); and on ISPs such as Plusnet who also hold and use a copy of the BT IP Profile check the copy corresponds to the BT one within a few hours of the re-connection..
