Pretty much the same here. 600 ohm balanced pair to the house. But if
you were to add a surge suppressor to the lines, like the old carbon
blocks or MOVs, or whatever, you would want to do it near the
single-point ground, and connect the ground reference of whatever the
protective network was, to the SPG. You still have to maintain the
balance and ground independence of the phone pair, though.

Just curious, how is the telco connection done in the states ? What is
there to connect to a single point ground?
Here in SM it is just two wires coming to the house from the telephone
pole, no screened cable to ground and no ground connection allowed on
any
of the incoming wires.
