The ringers for party line use were interesting too.
A standard ringer could be any of 1) across tip and ring
(single party line) or 2) from tip to ground or 3) from
ring to ground.
When a subscriber instrument on a multiple-party line
was installed at a customer's location, how did the
craftsman get a good electrical connection to ground so
that the ringer would operate properly ? Would they
clamp onto a cold-water pipe coming in from the street,
drive a ground rod, tap into the ground connection on
the electrical panel, ...? For that matter, wasn't an
electrical ground required at each subscriber location
[single or multiple party] for the line protector ?
They were (are) required to drive a ground rod. The
difference now is that only two wires, tip and ring, are
required to be extended to the actual telephone set,
where as with a party line phone using that method there
had to be 3 wires, with the ground also going to the
telset.
