What is the interleaving bit? Also what is the DLM that the engineer re-set? I am still having the occasional dropout since the engineer visit. Could this be a router issue?

Quote from: Olifran What is the interleaving bit?
Interleaving is error correction, basically. If any of the data that's transmitted to you is corrupted for any reason interleaving means that it's minimised and can be recovered without the computer having to request that the corrupted data is set again from the server it got it from. It does increase ping times though, but that's usually only an issue for those who play a lot of online games.
Quote from: Olifran Also what is the DLM that the engineer re-set?
DLM is Dynamic Line Management - basically an adaptive system at the exchange or in the case of FTTC the green box that adjusts the line to the ideal compromise of speed and stability. A slower line is more stable and less susceptible to errors, and vice versa.
Quote from: Olifran I am still having the occasional dropout since the engineer visit. Could this be a router issue?
It's more likely that your line can't actually handle the speed it's been set to at the moment and that's why the connection is dropping. The DLM system will adjust the line though and should slow it down just enough to stop the drops, at least that's what it's meant to do. Sometimes though it's a little over zealous.
Hope that helps explain.

This will cause the DLM to adjust the settings on your line.
Do you notice any interference or crackling on your phone line when using it?

Any ideas about the drops? Quiet line test seemed ok last night.
By the way can plusnet re set the DLM or is it an OR engineer that has to do it?

The DCN is referring to your drops in connection that you're experiencing, this is causing you to have a lower sync speed.
We're waiting for an update on the fault raised.

But said it was live so couldnt do anything, then he went underground. He was here for two hours and yes i guessed it,he re-set the DLM and something about a Triage Team who are specialist in FTTC?
So for the moment i am back up to speed , however I am expecting it to drop within a few days as the engineer has not fixed anything
