Hi hopkapi,

If you can message over your username I'm happy to the a look at your connection to see if I can see anything amiss.

Also, what is your speed estimate?

DLM does not set the sync speed. It sets various stability parameters.

Indeed.

I think Tommy *may* be lumping the IP Profile system in together with the whole DLM statement.

DLM does not set the sync speed. It sets various stability parameters.

Which in turn will decrease or increase the rate that the connection will sync at, hence DLM setting /controlling the sync as well as other parameters of course, And sends this to the bras where it generates the profile according to the sync speed negotiated by dslam and cpe modem
info contained within this thread seems to sugest something similar

The IP profile is in that way connected to DLM, But as far as the end user is concerned the IP profile serves to regulate the actual throughput, and occasionally the system that control this can have a senior moment or two, following a changing in sync if the sync increases but the bras profile remains at the previous value, throughput will be throttled back to its previous level set by the ip profile, until it either updates or is reset manually (if that is possible) if the sync decreases but bras remains at the higher level, no adverse effects regarding throughput would be observed, that's basically my understanding of how it works

Hmmm,

In all that discussion nobody seems to mention the ring wire.

Covered by Tommy;s excellent suggestion of using the test socket, which will be a 1st step diagnostic towards looking at the extension wiring.

Indeed.

Well. Two comments Tommy.

First, it's good to see you've been doing some research and are now getting close to what happens. But I don't need you to inform me about it - you will only find stuff that agrees with what I've been telling you.

Second, the link you give happens to be to the pirate copy of these forums. Or didn't you notice that . Maybe you'd like to find it on these and edit the link. Otherwise you increase their visibility on google .

Well it was google that found that link, for me,so i doubt it will make a lot of difference,
And no i ain't been researching how DLM works because TBH i didn't need to,

Does a re-synch always result in a lower IP Profile?

Tommy, stop digging yourself deeper into the hole when I've tried to offer you a hand out of it . Taking your latest wriggle:-

hence DLM setting /controlling the sync as well as other parameters of course, And sends this to the bras ...

Wrong. The DLM sets the noise margin; Impulse Noise Protection level and Fast Path/Interleaving. The difference between "setting" and "controlling" is huge. They are far having the same meaning, which is what you imply.

On all connections, including LLU, those same parameters are set by the ISP, be it dynamically or statically. That is not something special to the BT Wholesale DLM.

... where it generates the profile according to the sync speed negotiated by dslam and cpe modem

So we come to the nub of it. You now say "generates the profile according to the sync speed". Directly contradicting:-

In reply to a post by tommy45:

As for your speed, that is currently being restricted by the current Bras IP profile

which is all I did in the first place where the sync speed was being discussed.

In reply to a post by RobertoS:

The Bras IP Profile is set by the connection speed, not the other way round. Connection speed (15285kbps) x 0.882 = 13.48Mbps which is the IP Profile displayed.

Nothing at all wrong there. The reason for the low connection speed is what we need to look for. Sort that out and the IP Profile will track it.

The diagnostic tests you suggest might help.

It appears that I was wise in ignoring it .
