Generally, but as with EVERYTHING on the railway, things are never always the same everywhere and an exception will always be found.
Yes, usually when a point lever is in the frame, that is its NORMAL positon but that doesn;t alwayhs mean that the actual point will be in the "conventional" normal poistion, i.e. set for through running and not a diferging route. In one particular Peak District signal box, the "Normal" poistion of a point, (in the frame) is to send a train off the main running line and onto the Up/Down through Siding.
Also RE signals, yes normally a signal in the frame is ON, i.e. at Danger, but two signal levers (in the above box) when they are IN the Frame, the signals are OFF! and when they are OUT of the frame the signals are ON!
