Those who tested I understand, and EO too, but others unless their low end VDSL2 estimate is below their current ADSL2+ speed its worth a try, and for ADSL(ADSL2+) users even if same download speed the better upload can be worth it alone e.g. even if they go from 0.7 Mbps upload to 1.9 Mbps upload that will be noticed.

At least one won't be able to order as there too far from the cab. One is on the limit and would rather have a slow but working ADSL service then an extra mbit or 2 on a line that might not stay up any better. Several don't want the 12 month minimum term (very limited number of providers do monthly)

I agree the upload would be great (especially for me) but I cant have a line that's going to end up interleaved or banded after rain or in the winter when the noise floor comes up - with no way to remove it, my line plant isn't great, we are OH fed and suffer breakthrough and many missing tones due to medium wave TX'ers

Issues with X-Talk and ever reducing speeds have left at least 2 others shy of bothering at the moment (They wanted the 80mbit service, but locally people are down to about 65 in some places) - They may defect to VM shortly I suspect.

And one mad/lucky person who's looking at FTTPoD!

Annoying as this is, what you are seeing is DLM working as expected. Does it warrant an engineer to visit, because a setup is performing how it was engineered to?

Ultimately, in the absence of interference, a fault and/or disconnections your line would not have been banded. In your case as it was a fault I would expect a fairly quick recovery (say a few weeks). Certainly when I had a fault the banding got removed after around 14 days and interleaving around 1/2 months after. Full recovery about 2 months for me but this was back in 2012.

I totally understand what you are saying and agree that DLM is doing what it should be doing BUT the fault was caused by the uplift work that BT were doing at my cab which caused a loose joint and BT have admitted as much - which I have it in writing (albeit an online chat log).

When they rang this AM to cancel my appointment, they said they were doing it because an engineer had done the DLM reset. I don't believe this for a minute as it should have caused a disconnect and also reset the banding.

I am of the opinion that, as it is their fault, they should get an engineer to do the DLM reset for me.

I think all the engineer did this morning is swap me to a different port at the exchange!

Well despite BT cancelling my engineer appointment yesterday, telling me the engineer had fixed issue, I had 14 resyncs overnight so something is seriously wrong.

Do I have grounds to ring BT an insist they send engineer? If anyone wants to check, I'm Tenbyboy2 on MDWS.

You can insist, but whether they will is another matter, and its possibly more of a battle convincing the retailer than it is open reach

Must be so difficult for them to source an engineer or someone who can spend a minute putting your phone number into an automated telephone service to reset the DLM.

There are arguments all around DLM its such a touchy subject but if you advertise your service as most do nowadays especially for multi user household use and 'gaming' then you have to be willing to clear any sort of interleaving after a hard fault has been fixed.



Nobody should expect perfect internet but simple things like this are all the difference OR need to realise this.

I have yet to have any Openreach engineer who's flat out refused to do an DLM reset just before leaving after a visit.

DLM reset is not done from a phone number. It's done with an OGEA reference which the engineer can only see on an FTTC fault job.

I concur with that as it is the reason this all started in that the engineer that came to fix the phone line fault didn't have an OGEA reference as it was only down as a line fault.

Got home at lunchtime and couldn't hear an answerphone msg due to all the noise on the line - it was back!!

Straight onto BT chat and she did a test and said there is a fault and has booked me Engineer for Saturday morning. I also told her about the now 21 resyncs I've had in 18hrs so there was a mention of that in the notes.

She said it was to fix the line so I asked her to make sure it is for Line and Broadband as last time it wasn't and he couldn't do DLM reset. I said he needs access to OGEA reference and she she said she'd make a note.

I have even recorded the noise on the line this time as it wasn't so bad when engineer arrived last time
