Is DLM applied on my line?

Go to solution

Hi,

I have been on Superfast Fibre 1 for a couple of years now, with speeds capped at 55Mbps. I have recently upgraded to Superfast Fibre 2, with Point of Sale speeds quoted as 64Mbps as the lowest, and 73Mbps as the highest. The minimum speed I should expect is 56Mbps.

 

However, today I called BT regarding the speeds, and they ran a speedtest & found that between the Exchange and the Hub, the speed was 53.2Mbps, and between my hub & device was 53.2Mbps too.

 

Looking in the Technical Log on the Smart Hub, it shows the below details;

DSL Checker shows;

I am wondering if the technical log looks okay, and whether it looks like DLM has been applied here? The data suggests the maximum could be 74Mbps, if I am not mistaken? If DLM has been applied, is it possible to have it removed/reset?

 

Thanks in advance,

Ashley

What did they say when they found the speed to be 53Mb?

Did they advise connecting to the test socket with a filter? If not please do so.

Also conduct a quiet line test (best with corded phone) 17070 option 2, any noise report a line fault on 151.

 

BTW Your stats suggest DLM is active on your line.

Thanks for your speedy reply 🙂

 

They said it's not normal, but they don't know why. I am already in the test socket, for my Infinity SSFP Mk3 socket, with no success.

 

No noise on the line from what I can hear.

 

This is also the result showing on Wholesale's test using an Ethernet-to-hub device;

Thanks for the assistance so far! Is there any way to have DLM removed/reset yet on VDSL? I've searched and saw that some people have had success through a Moderator, but it seems hit & miss.

DLM is always active. Perhaps you mean banding has been applied.

DLM is usually applied because of error/fault on a line. It is pointless getting DLM reset if the problem causing it has not been resolved because DLM will just re-activate after a short time and you will be back to square one.

You should report a problem to BT and request that an engineer be sent out to investigate why you are not getting better speeds. Assuming a fault is found the engineer should then request a DLM reset.

The moderators only request a DLM reset if either the reset was not requested or it is apparent that after a repair and reset DLM has become "stuck".

Thanks gg30340!

 

When I spoke with BT earlier, they ran a fault flow & found no faults. I'm guessing it's best, as you say, at this stage to get an Engineer out to see if there is actually a fault the system hasn't detected.

 

I'd be pretty confident the £85 Engineer Home Improvement Service fee shouldn't apply in this case, since I've performed own domain checks. I know BT were warning me of the fee before I let them go on the phone earlier.

As you are connected to the test socket then the fault is external providing no extentions work.

@licquorice Yes I did mean DLM applied.

There’s one extension in the house, but has never been wired into the master socket. Cables are there when I removed the faceplate.

Thanks for your help guys - I’ll see if I can get BT to arrange an engineer for me.

Hi @MrAshieB,

I'll be able to take a look at your connection and arrange an engineer if needed. You can send me in your details using the "Contact The Mods" link found in my profile?

Thanks
