In rural settings it is understandable as given the sparse population density it would make more economic sense to deploy the standard telephone system that way when there was no advantages or disadvantages to being that way.
Now however with FTTC there is a huge disadvantage to being on EO lines.
What are the current Openreach, or indeed industry, plans for providing "Super Fast" or such to EO lines.
I would estimate probably 50% of phonelines on small rural exchanges (sub 1000 lines) are EO lines.
I know my preference would be simply to replace the copper with fibre and provide FTTH, but I doubt that is practical from a BT cost point of view. FTTRN sounds good, but again given the low population density is that practical.
Rural properties are often affluent, but even for residents willing to pay a premium many are still stuck on ADSL Max up to 8 Mbps, and often only receive a fraction of this.
