Hi, I'm currently on the plusnet 40/2 package and trying to figure out what sort of speeds I would get if I upgraded to the 80/20 package. My stats are on MDWS. The attainable stats are below but I was thinking I would get a higher sync than this as the SNRM would go down to 6 when on the 80/20 package ?

SNRM
Down - 10.1
Up - 26.9

SYNC
Down - 40000
Up - 2000

ATTAIN
Down - 49008
Up - 9155

ATTENUATION
Down - 24.3

You should get close to your attainable sync with say 48000 kbps on the Downstream and 8000 kbps on the Upstream, most of the time you can't rely on the attenuation on FTTC I will always go with the users knowledge of distance to fibre cabinet.

[GigabitEthernet]

You've got a lot of spare SNR on the upstream, so I'm thinking around 9Mb for the upstream.

You've got less (but still a bit of) SNR on the downstream, so I'm thinking about 50Mbps on the downstream.

[burakkucat]

Your target SNRM has been set high to cap your circuit to 40/2 Mbps.

Let's work on the assumption that the current (approximate) 10 dB DS & 27 dB US are reset to 6 dB DS & 6 dB US. The difference is thus (approximately) 4 dB DS and 21 dB US. Not knowing how your circuit behaves over a typical 24 hour period, we now need to estimate what those differences could give you . . .

   Hmm . . . somewhere in the ranges of 48 - 51 Mbps DS and 8 - 10 Mbps US, possibly. 

What is the prediction when you input your telephone number into the BT Broadband Availability Checker?

[big360]

Thanks for the replies. You can see the historical stats on MDWS if interested.

Here's the DSL checker estimates. The cabinet has had FTTC for a couple of months so I guess I could lose a bit more to crosstalk in future. Maybe should wait till vectoring goes live?


                                      High   Low    High   Low      
FTTC Range A (Clean)   44.6    32.4   8.8   6   --   Available
FTTC Range B (Impacted)   38.2    22.4   8.8   4.5   --   Available

Having seen Beattie's prediction, it might be wise to just wait and watch. I think you will only see a really significant improvement in the US direction and so the question -- Is it worth it?

In the light of that new information, I wonder what N*Star and AlecR think? 

[GigabitEthernet]

An 8Mb upload is quite a jump from 2Mb. Would your Internet activities be helped significantly by that jump?

If not, I cannot see the upgrade being worth it, unless the cost is very similar to what you pay now. In my case, with TalkTalk, an 80/20 connection was only £5 more a month than the 40/2 package, so I thought the extra cost worth it.

I don't know if I'm missing something obvious here, but the 'Attainable' mentions the maximum your circuit will support ?? I can only go off my JDSU findings when working on various circuits, but it doesn't matter what the existing package the EU is on ..... it will always show the maximum the circuit can achieve.

[roseway]

BS is right of course, although the attainable figures can become suspect when interleaving is at a high level. In this case the attainable values look to be realistic indications of what to expect from an uncapped connection.

[GigabitEthernet]

My estimate quite nicely matched the attainable rate, no?

Black Sheep,
Is that true because the 40/2 service is a capped 80/20 line ?
Is there anyone who provides a 40 service without capping?
(Sorry for dumb question)
Very useful to know as you can estimate your upper limit without having to take a punt on the 80/20 service and hoping it is worth it, then downgrading if it is too marginal an improvement.

[Black Sheep]

I have no idea how it works, I'm afraid. All I can honestly say, is that if the EU is on say a 40/2 circuit and is close to the DSLAM, our Hand Held Testers will show the full attainable rate.

I'm guessing the 'Capping' is done further down the circuit ?? 

[renluop]

May or may be not relevant, but I believe that PN does not use the higher estimate that BT does. I think then that they would not permit 80/20.

[big360]

Thanks again for the replies. Currently on a discounted offer of £11.99 a month for the 40/2 service. As the 80/20 offering is £5 more than 40/2 would assume I could upgrade for an additional £5 a month if they allow me to with the BT estimates below 40.

What I would really like is an addon for say £2.50 a month to switch me to 40/10 but plusnet don't do that. I think I'll wait it out a bit longer and see if crosstalk lowers the attainable even more over the next few months.

[tommy45]

I would migrate to a provider who offers the 40/10 unlimited product, plusnet and tt are non professional shysters  IMO A 2mbps upstream rate for a VDSL product Joke!!!
