A google search indicates the Lantiq chipset may well have settings to adjust the upbo, but I've found nothing to indicate the actual cli commands.
Time to get the ECI modem from the back of the cupboard and start playing

AFAIK upbo is intended for use on short loops to reduce crosstalk from them interfering with the signal coming from more distant subscribers. I'm on the end of 1 Km of mixed copper and aluminium, I doubt a strong upbo settings is intended for this type of line.
I've notice in "My BT" that BT have now marked this fault as complete!
Still getting the same 0.5Mbps upstream sync on my VDSL connection. How on earth do you contact anyone at BT support with the slightest knowledge of how VDSL works or who has any interest in trying to help paying customers.
