Dlm 2?

[Saturday]

DLM on my line finished a few weeks ago, knocking just a hundred k or so off my 12.5meg connection giving me a nm of 7db rather than the uncapped 6.9db (the change was day 1 and it stayed static thereafter for the 3 weeks of DLM daily resyncs, so who knows what that was about). Subsequently I've had well over a 1000 hours uptime showing in my router stats. i.e. not a single drop out - though I never had them pre DLM either. My line, pre and post DLM has only the error level you'd expect for a fairly fast ADSL2+ line.

Now, for the last few days I'm getting a resync every morning around 3am again. Looking at other posts in the forum, a couple of members have reported the same thing.

Surely DLM hasn't come back?

God help us if it is

My DLM Nightmare lasted over 1 month.

Don't think DLM ever went away to be honest.

That was what I thought. DLM runs for a training period of 10-20 days, then stays on your line, unless it is manually removed. There would not be much point in having a dynamic management system if it was not going to run all the time.

Not exactly dynamic at that point lol All I can say is I hope Sky has tweaked it a bit if they are running it back out again in earnest. That or at the very least send a flaming email out this time to the customers being hit by it

Hmm. There's DLM and there's DLM.

"Real" DLM would progressively adapt the connection depending on the prevailing line conditions - a bit like SRA but exchange based and probably not as granular. It wouldn't have or need a "training period", with the possible exception of new connections. As far as I'm aware, Sky's DLM was only applied to existing, and in many cases, long standing connections.

I can see little evidence that what Sky call DLM is any such thing. It looks like a roll out of their rubbish reprofiling tool to me (the one that T1 kicked off whenever they got a call anything remotely to do with a connection/speed problem) but with some automation, or quite possibly, an adaptation of BT's archaic RAMBo approach, if so, having removed, it would appear, the basic intelligence that system contains.

However, the point I was making by rhetorically asking whether DLM was back, was that I was under the impression that Sky had removed all existing "trial" customers from DLM as it had clearly not been a complete success.

Maybe I misunderstood.

It would be helpful if Sky provided some further info on this, not much has been forthcoming after the initial announcement.

I hope you are right about them scrapping it, I wasn't subjected to it and don't want to be

In a way I'm glad I switched to O2 (BE)...not only is support 'user friendly' but the connection is solid and fast.

When I first signed up to Sky they profiled my line as 8mb and stuck me on standard ADSL. Thankfully a kind sole looked into this raising the bar to 11.5mbps however when DLM was introduced I was shunted down to 10mbps.

I switched to O2 (BE) and on 1st connection to their ADSL2+ service I was getting around 12mbps, a quick tweak by a support agent and it jumped to 14.5mbps.

Either Sky is airing on the cautious side by artificially profiling lines to what they think is acceptable or the DSLAM's they are using are different/inferior to what O2/BE are using.
