Am thinking of leaving sky, to try somewhere else, as sky seem to restrict your SNR and don't seem to want to try and get your speed as high as it can be, i was thinking of trying Plusnet out, as they offer phone services and broadband for about the same price i am paying to sky, it is not unlimited but you get 60Gb and unlimited from 12am-8am which will do me, only trouble is it is a ADSL product and not LLU like i am on now, has anyone had any capacity/speed problems with Plusnet, i used to get them before when i was on ADSL but not since moving to LLU, i don't think i was on Plusnet at the tme, just to clear that up, any advice would be great?.

Remember that moving from LLU will introduce the IP profile which is an artificial limit of your speed. In the new system this is 88.2% of the sync speed

It isn't that important any more Jim  . Particularly moving from Sky, which has a 7dB target noise margin, where a decent WBC line now gets 3dB after a while.
The IP Profile loss includes a fair chunk of the overheads. For instance, the maximum throughput on Be/O2 is around 84% of sync.

Good point - I will remember for the future as I get about 100kbps less than the 4431kbps IP profile on speed tests

If you are syncing above or near 8Mbps at present I hope you've checked that your exchange isn't still on 20CN only!

Yes, we need to know if the exchange is WBC-enabled. Otherwise your point about below 8Mbps, and therefore the old style DLM/IP Profile/Noise Margin system would apply. It doesn't really matter what his current sync is.

So is it a good idea to move from LLU then, at the moment the sky technical support and the fact sky limit the SNR to 7 is the reason why i want to leave them, and the fact my line was syncing at 19mb but now it isn't and they don't want to do much about it, i have just looked at my exchange and notice it says (21CN WBC status: Enabled) is this a good thing, i am not totally sure what this means, also how do you get to talk to the support team live on the website, it popped up last night on my screen when i went on the site, but i cant seem to find the link to get too it now.

Yes! If it didn't say that the maximum sync speed would be 8128.

I see on the site it says the max download speed is 16Mb, is that really the max or can you sync higher?.
|
|
|
Now you see the effect of the new rules http://www.thinkbroadband.com/news/5135-is-speed-to-...
In practice the 16Mb refers to the speed achieved by the top 10% of customers The words UP TO if preceding a speed figure e.g. 6 Mbps should mean that at least 10% of the customers using a service can experience this speed.
|
|
|
If you see any ISP advertising up to 20 it's odds on they will be in trouble with the ASA!

I think sky advertise there product up to 20Mb, and i sync at 17Mb, so is that just what they advertise up to, can you actually sync higher or is it limited to 16Mb?.
|
|
|
Theoretically, if you are practically next door to the exchange you could sync at 24mbps.
In accordance with the new rules that Jim linked Plusnet can only advertise an up to speed that at least 10% of their users achieve.
If you put your attenuation in to http://www.kitz.co.uk/adsl/max_speed_calc.php it will give you an estimate of what you might get.

Right, so plusnet don't limit the sync to 16Mb then?.
|
|
|
|
Correct
|
|
|
Sky advertise using a 14 Mbps figure, this is the new figure they started using last week.
Some comparison engines have not updated yet, and many providers have not either. Am expecting a lot of complaints to ASA, particularly from those following the rules against those that have not bothered yet.

This has to be one of the daftest rulings ever, how is this supposed to be in the interests of the customer? Even more meaningless "up to" figures than before and harder to identify what product is being sold.

It isn't as if most even care, and those that do now have stupid non-information, as you say.

Superb typo.
That's nearly 68kbps then?

Nice speed, what is your attenuation to get that kinda speed, mine is 17 and i only sync up at 16898 ish, used to be over 19000 but then it dropped for no reason at all, i think sky are messing with my connection and now they wont put it back.

|

Oops I'm sure there was a capital K when I typed it and it was seconds
24383 Kbps
got it right finally.

Attenuation is 5.5
SNR margin 3.5
|

Probably explains why your sync is much better than mine then, but sayin that i did have a sync over 19000, dunno what has gone wrong with it though, cant seem to get it over 17000 now.

The "k/K" is not the issue. We all use "k" anyway.

Suffice to say that many people agree
Results from our poll
Do you support the requirement that broadband advertising only
shows a speed that 10% can get?

What's your noise margin immediately after a resync? With your attenuation you could expect over 20.

At the moment my SNR is 7.1, i would of thought my sync should be something like that, it used to be over 19000, but for some reason it went down and sky wont do much about putting it back up.
|
|
|
I've read elsewhere that their default noise margin is now 7 so that ties up. If your line is stable and could run with a lower sync they are restricting your speed unnecessarily.

My sync was higher than it is now with a 7 SNR limit, but for some reason it has gone down and wont go back up, dunno if it has something to do with sky messing about or it is my line, just weird how my sync was always over 19000 and now it wont go near that.
