Would it have the same effect as a DLM reset?

[licquorice]

In my experience it would perform a DLM reset but not remove any banding applied.

[N0STIE]

From my experience, indeed it does perform DLM reset.

I'm confused here, licq ?? I my experience, whenever I perform a DLM Recalculation (Reset) after repairing a circuit, whatever banding was applied is always automatically removed.
The only time a DLM reset won't happen, even though it has been requested, is when the circuit in question is already on the open profile ...... ie: 128kbps-40Mbps, 128kbps-80Mbps .......... unless I'm missing something here ??

Well all I can say is there was a DLM reset when my Infinity1 cap was changed but I was still banded afterwards (and still am). There was a thread some time ago positing that there are 2 levels of DLM reset.

Yeah, if you don't have a banded line, then changing products will mean a DLM reset, however if you do, then everything but the banding is changed in a DLM reset. All I did was talk to BT live chat and they sent me a broadband boost engineer (the guy who picked up the job was a guy called Glenn who we know very well) and did a DLM reset from his van, this removed G.INP but a few weeks later it came back and haven't had a better connection since!

Really I've never heard or had discussion with anyone, (including Btw and our DCoE) about 2 levels of reset ?? There are certainly levels of manual intervention that can be applied, but this is a new one on me ?? Que sera ….. we live and we learn.

Perhaps as DLM doesn't appear to want to remove banding automatically, it doesn't like removing it when applied manually!! 

[William Grimsley]

Was this aimed at me? All along I did say I was "testing" how DLM worked, but after a while it should of reset itself but didn't hence the Openreach engineer visit was required.

Ha ha ......... tis' a stubborn bar-steward for sure !!!

Err, no. Why would it be aimed at you? It was a slightly tongue in cheek (with a hint of the reality) reply to BS

Ahh, ok. No worries, just thought this was aimed at me, but it's true isn't it?

It was my speculation, amidst Kitz's discovery that we saw some resets remove FEC+interleaving, while some put it in place deliberately, at least for 2 days.

Alongside this, there seemed to be something "above" DLM that controlled the permissions that "ordinary" DLM was allowed to work within - particularly whether various forms of retransmission were permitted on a line, in response to the client modem capability.

The fact that banding does not appear to be removed in a DLM reset (or at least some forms of reset) continues this speculation. After all, surely, there must be a form of reset that *can* remove banding?

Yes, the NGA reset removes banding which was performed on my line earlier in the year.

Hmmmm ?? There is more literature to be read on DLM than there are stars in the sky  .

From what I can glean though, whether it's a 'Baseline reset' or a 'DLM reset' ...... the variable memory is removed, and all DLM counters and history will be reset, basically putting the circuit back to 'Open profile' on whatever policy is in use (40M/80M DS ... 2M/10M/20M US).

I can't find anything that mentions holding on to the banded profiles via a DM reset (or recalculation - both the same) ??.  Strange.
