I was assured both by sales livechat and by the installation engineer that my connection would be FTTP (ONT outside, coax through the wall, as documented in various images I found of Lightning installs). But my end result looks a lot like a normal ye olde coax install.
In particular I notice there's no extra reverse power cable for an exterior ONT. Unfortunately I didn't take a peek inside the exterior box while it was being worked on.
Either Lightning now uses the old-style exterior box with a smaller ONT and gets its reverse power from the Hub... or I was sold FTTP and got HFC. Can anyone confirm?
