The Engineer was good. Quick and explained things clearly. I do find it slightly odd though (and this I’m sure is procedural) why using existing holes in the wall for the redundant master socket could not be used for the ONT installation. It’s also odd why they don’t take a few minutes to decoration the old copper master socket; the two are mutually exclusive. This is not a negative on the Engineer, more a frustration with the installation process as I now have both a redundant master socket and an ONT on my wall.
