When the E side isn't needed...

I have a fiend who is on the end of a very long line (about 2 miles). She used to get just shy of 2Mbps on ADSL.
A new AIO cabinet was put in down the road, and now she's getting a solid 40Mbps on VDSL. However, she still gets frequent disconnecitons - I'm guessing this is due to issues further down the E side.
My question is this - she doesn't use the phone line for anything other than the internet. Yet there's a big long piece of copper causing stability issues. As far as I know BT won't separate out the line before and after the cab - but wouldn't it make sense to? This isn't a cost issue, it's more about stability. Can this be done?

Not until they are allowed to do so, i.e. LLU requires the E side to remain in place

Interested in how you've diagnosed the issue as being on the exchange side of the cabinet

Also currently needed for line testing

I thought on FTTC that the DSLAM filters were supposed to eliminate E-side noise?

I�m fairly sure one of the engineers posted that here years ago, and moving to it certainly stopped the disconnections I was getting several times a week on ADSL2+.

If there is noise causing FTTC problems surely it is D-side?

The cause of the issue could be anywhere along the line including in the friend's premises, you have not said anything about a noises line or spells of no dial tone which I assume would be hard to detect as your friend doesn't use the line for making calls.

[Edit] Just trying to make the point that its not necessary on the E side.

This was my thinking too, hence asking how the poster has diagnosed the E side as being the source of the noise.

In reply to a post by MrSaffron:

Who said anything about a noisy line?

Yes. Last night I saw you ask that, but forgot just now . I�ve just noticed also the OP said �I'm guessing ...�. Wrongly I think.

This instability, was it present on the slow ADSL? If not, it seems more likely it is a new problem on the D-side, or in the AIO cabinet.

Is the router disconnecting and re-sync�ing, or is it just the wireless connection to it?

Is your fiend using a dangly filter, and if so does the problem still occur when using the test socket?

"I'm guessing this is due to issues further down the E side"

An implication from this statement - happy to entertain other descriptions
