Another question around a "1 Stage" install if that is the case as DSL Checker states. And going back to the earlier post about the existing UG being a direct bury from the late 60s and infact it will be delivered by this pole at the rear side of property just recently installed.
My sister-in-law had a recent FTTP install, row of terraced houses where the original POTS was distributed from a JB, wall mounted at the front of the middle house with the respective house lines run along the eves, quite a common distribution method.
However, in this case, OR opted for FTTP fibre arial distribution at the rear of the houses from a newly erected pole/CBT.
So yes, OR fibre installation methods can vary dependant on the local logistics.
In my area, with existing POTS DIG installations, OR seem to opt for a completely new fibre run from the footway CBT chamber/toby box across the garden to a new entry point on the front wall, or where there is existing POTS cable ducting which may be partially blocked, this is broken into as near the dwelling as possible, fibre extracted, direct buried and run to the new designated entry point.
