21CN switchover and training period

ADSL Link Downstream Upstream
Connection Speed 7680 kbps 992 kbps
Line Attenuation 33.0 db 14.5 db
Noise Margin 6.0 db 11 db

My line was switched over to 21CN this morning. I believe im still on adsl1 as i did not request adsl2+, so its just the exchange stuff that changed.

The email i got my my ISP mentioned a new 10 training peroid similar to when you first get adsl on your line. Does this training period count if you havent been upgraded to adsl2+ and still remain on adsl1 on 21cn?

Asking as ive had a few disconnects since being swtiched over

You are on ADSL2+. The maximum upstream on ADSL is 832Mbps and you were probably on 448Mbps anyway.

Have you any previous stats? If you have, also check the downstream connection speed and attenuation.

Downstream before was 7616, so only slight improvement. Line attenuation was 32db

I thought with a attenuation of 32db (or 33db is it now) i could sync faster than that?

Ping has improved too by quite abit

You should be able to connect much faster than that. It is either your local wiring or it could be the way their training works (Sky for instance start at 4Mbps and over a period of some days increase it).

Yes, I agree. I think he is on ADSL24 though.

Time for him to ask them I think .

14Mbps or so. Which package are you on? How up-to-date is your router and its firmware? What is it?

Yea adsl24. tbh id settle for a stable line over a fast one anyway. 8mbit is plenty for my needs, and ive increased my upload speed and my ping which is good.

Im guessing they wont do anything until the 10 day training period anyway, so will wait till after that and take it from there. They did state in the email they sent me that i would have to request an upgrade to ads2+, hence i wasnt sure if i was on it or not

Its a Netgear DG834Gv5. Its not got the newest firmware update on it, its got the one before that

Says on there the router isnt great with adsl2+, even tho its advertised as adsl2+ compatible

That looks like your problem then I'm afraid.

There is a bit of confusion in that thread, even for when it was current. I thought the version number was on the label on the product, but not on the box.

Netgear 834v5 is Conexant, as is the 834Nv2.
834v1,2,3 and 834Gv1,2,3 are TI AR7. May be OK but not on Be LLU. But you aren't on that.
834v4, 834Gv4, 834GT and 834Nv1 are Broadcom. Fine.

Difference between 834 and all the rest is they have wireless and it doesn't.

Once you get a router that works properly the 10-day period would need re-running, to reset your Fault Threshold rate. All it does is set the Maximum Stable Rate and the FTR, and those are going to be incorrect due to the low sync. 10-day training.

No ISP should be concerned about the 10-day period when there is an obvious problem. The 10-day period is irrelevant in such a case. The user's difficulty is in getting that through to them.

Yea i suspected the router at first aswell. As i said tho its not something im overly concerned about. Id rather stay on the speed i have than risk going to 14Mbps and making my line more unstable.

Just got this email from adsl24

We are pleased to advise you that your line has now been upgraded to the BT 21CN platform.

You are now able to regrade your service to the ADSL2+ frequency which potentially offers higher speeds at no extra cost.

Should you wish to regrade to ADSL2+ you can do so by raising a ticket or by contacting us, however please remember that you will need an ADSL2+ compatible router.

So that suggests im not on adsl2+ yet? Is there a chance im on some kind of capped adsl2+ service? Hence the increase in upload

You are probably on ADSL via WBC hardware, or a capped profile that emulates ADSL like speeds while delivering ADSL2+.

Some modems report the mode they are connected at which avoids all this doubt you are having. Personally I'd go for the ADSL2+ as you should be able to run nice and fast

I don't think the WBC "ADSL" profile allows 992kbps upload does it Andrew? Maybe it does .

Can't say for sure here either.

Two many DLM systems to remember everything now, and very long Ofcom documents dont help

In reply to a post by MrSaffron:

Agreed.

They get longer because the author of each new one is equally confused about what has gone before, so has to start from scratch.

Yes, it does (and always has).

As soon as a line is upgraded to 21CN, we have the option of a capped 448k (as like 20CN) or an uncapped upstream, i.e. up to 1.4Mb. This is seperate to ADSL2+ which will increase the downstream.

We provision all upgrades to 21CN on the uncapped upstream by default, but on the 8Mb ADSL profile on the downstream, so yes, the customer still needs to request the ADSL2+ upgrade to see higher downstream speeds

If you PM me your line number I can place the ADSL2+ modify for you - it only takes 24hrs to complete.

Thanks James .

(Simples, then. ).

Your post is clear. The reasons it is done like that by BTW, less so.

Yep. The reason they actually allow an uncapped upstream on the 21CN WBC ADSL profile is because of Office packages, who previously benefitted from 832k upstream on 20CN Max Premium packages, so they had to offer the equivalent (or better as it's uncapped up to 1.4Mb) on the 21CN WBC ADSL profile, but we're not fussy and just let everyone get the max upstream their line can take rather than cap them at 448k.

D'oh!

Obvious once you know .
