Interleaving - Why turn it off?

[#1]

From what I read here https://community.plus.net/t5/Plusnet-Feedback/Interleaving-Why-turn-it-off/m-p/1577957#M82603 it was the DLM that automatically switched it back off, not Plusnet.

Hi @Boz,

Thank you for getting back in touch. I'm glad to hear that your connection looks to be more stable now and I'm sorry for any inconvenience that this issue caused.

Please let us know if you experience any further connection problems or if there's anything else that you'd like to discuss.

I'm sure I read somewhere that the DLM's were now controlled by the ISPs.

Are you referring to this https://www.ispreview.co.uk/index.php/2018/02/ability-reset-openreach-fttc-broadband-dlm-profiles-ar...?

If so note that this says that Plusnet can request a DLM reset. That doesn't mean they can switch interlacing off or on themselves at will.

Anyway, if the line is running fault free why would you want it permenently on?

I assume this is ADSL we are talking about, for which it has been possible for a long time for an ISP to set a line to have interleaving on or off so that the DLM will then not change it.

I had ours set to always on ages ago, because basically it's better with it on than off. Our line gets more bandwidth and fewer uncorrected errors with interleaving on than without. I don't particularly care about the latency, which isn't particularly high anyway with it on, so why wouldn't I want it on?

I stand corrected. I hadn't noyiced that the OP was on ADSL.
