In fairness, it’s nothing short of sheer voodoo what they managed to do with the simple copper loop. As usual though, it was the rural communities that felt the pinch (and the gains) more than most though.
The chances of it being the filter were stupidly low, and I don’t think I ever had a case of the filter being at fault - but it was one of those potential issues that would make a customer look stupid (and £120 lighter) if BT tipped up and declared it a customer equipment fault.
In newer homes (at the time), there were NTE faceplates that had a filter built it, with individual ports for telephone and for data telephony cables. They didn’t last long though. Maybe they were stupidly expensive in comparison, maybe BT could see the fibre future and stopped producing them.
This is actually true though. With ADSL you needed a filter to split out the ADSL line with the phone line.
