rjh,

What do you mean by 'DLM intervention'? Do you mean that, the line having been stable for some time, suddenly decided to re-sync?

And 'REIN' stands for?

It looks like adslmax is no longer using this topic. I'll give him/her a few more days to respond, but if I see nothing by then I'll try getting in touch with him/her via a private message.

"Him" .

Bear in mind these power supply plugs are really cheap stuff and no doubt highly variable in quality even from the same manufacturer.

He may simply have had a rogue one.

Crikey, that's a thought.

Sorry, it's easy to assume that everyone knows what I'm talking about.

Anyway, DLM is the system that monitors the line and tries to correct it when there are too many errors. In my case, it reduced my connection speed. I check this using software which works on my unlocked BT modem(they are supplied locked so that we can't access the figures!).

REIN is Repetitive Electrical Impulse Noise, a kind of electrical interference. There's a good breakdown of the various types of interference on the kitz.co.uk website, in the ADSL section.

I'll add that an intervention by DLM is, when monitoring the line, it decides to make changes to the line profile in order to improve the number of errors happening. The usual first step is to add FEC (forward error correction) and interleaving, which steals some of your bandwidth (to allow the error correction to function) and increases your latency. Subsequent DLM steps tune the settings, in attempts to cope with different types of noise.

Each intervention causes a re-sync that looks spontaneous to the end-user. Such a resync usually occurs between midnight and 8am.

However, not every re-sync is something triggered by a DLM intervention.

Billion 8800NL are now back in stock http://www.broadbandbuyer.co.uk/products/18474-billi...

adslmax,

Have you noticed that I've asked you about your power-supply problem, about a webpage or two back in this topic?

@ meditator - as for power supply u have to investigated it yourself between openreach modem plug and billion 8800nl plug as I have found billion 8800nl are less noise with openreach plug. (the white plug)

ES 30 with openreach plug (24 hour)
ES 71 with billion plug (24 hour)
