In the meantime, I have done a little research, and I see this term "banded" being used here and there - does that apply to my line? I have no idea.
If you could help me, and also if you could tell me if EE are competent enough to actually sort this within the specified 48 hours, that would be a great help.
I've just spoken to my neighbour who is an Openreach engineer, and he tells me that sometimes the line cards in the exchange (System Y, in my case - Ericsson switch - AXE10) can overheat, which knocks them out (understandably). He's said he can come and plug his "special bit of kit" (his exact terms... haha) into the line and do a throughput test, if the fault isn't sorted in 48hrs.
Thank you folks
