Most likely most people lost both wires in their pair and this person was the lucky one

I have a family member who currently gets less than 1mbps over ADSL. We understand the lines in their village are aluminium, which I believe is a fair bit of the problem.

The BT checker rates their line as "ADSL Max Up to 1 -- 0.75 to 2.5 Available".

Reports from other villages in similar circumstances suggest that VDSL is not operating very reliably, and speeds are small fraction of 40mbps.

Is it likely that this new ADSL service would be better for them than VDSL?

Appreciate any advice.

cheers, Martin

IF it becomes available then largely depends how long the line is from the cabinet

Do you mean a short line is better for VDSL, and longer for ADSL? I guess you can't mean the other way around?

So, where is the cutover likely to be, in terms of line speed or attenuation or SNR? Again - specifically in relation to aluminium lines from cabinet to home.

cheers, Martin

Both service operate best on shorter line but ADSL can operate better at a longer distance than VDSL....

This is because VDSL uses higher frequencies than ADSL and "evaporate" quicker (if you like) than the lower frequencies of ADSL.

To answer your question "will ADSL work better than VDSL" yes it will but always depends on line length from the cabinet.

Thanks. Given my question was specifically in relation to aluminium lines, can I confirm the answer is also in relation to aluminium lines?

Yes, ADSL will work better over aluminium lines, and considering your current sync rate I would be shocked if that didn't at least triple.

Given that we know nothing about the distance from cabinet to house, it is hard to say what the impact of putting an FTTC cabinet into the village would be.

And because we don't know the distance between exchange and cabinet, we can't know whether cabinet-based ADSL (or 2+) is likely to offer any improvement over cabinet-based VDSL2.

Getting an accurate answer right now will be impossible anyway, because we know very little about what BT intends to do; all we have seen so far is the testing process that they will use for the customer-end modems. The best we can do is speculate wildly.

Finally, in terms of the aluminium, that is pretty hard to gauge. Like copper, speeds also depend on the diameter of the aluminium, not just the length. It also depends what proportion of the length is done in aluminium; it may be partly copper.

vdsl does also use adsl frequencies , so yes it does use higher frequencies but it still uses low frequencies as well.

From what I see the main reason why vdsl is bad at very long distances is the adsl power cutback.

So if I'm correct you mean the output power of VDSL is low compared to ADSL as it would kills signals on VDSL hence it not having a greater reach.

Which would also mean they would maybe reduce power output of ADSL2+ from an NGA as it may interfere with VDSL signals.

As mentioned previously there's not really much to speak of at the moment as not much detail has been released.

Though a question on my lips is would the ADSL DSLAM be completely separate to VDSL DSLAM or would it be the same equipment with a dual mode activated.

And am I correct in saying that only non LLU providers would be able to use the service if enabled and also would it be active in selected areas or would it be available everywhere VDSL was.
