Thanks for your post @bb21081 and welcome to our Community Forums.
I've placed an order with our suppliers to change the provisioning of your broadband service to permanently turn off interleaving which should go through on Monday as the next working day.
Currently it's in an automatic mode which means the automated dynamic line management (DLM) software at the exchange will toggle it on and off as it sees fit to try to keep line errors at a minimum.
I've also prodded the upstream SNRM target up to 9dB. Let me know if you have any further issues.
From 31st October 2022, I no longer have a regular presence here as I’ve moved on to a new role.
