I knew some guys in the Chicago suburbs circa 1965 who had their own
private telephone system among them. They had learned it was possible
to lease burglar alarm lines very cheaply from the telephone company;
and in fact when you leased one you got an ordinary wire pair that
worked just fine at voice frequencies. So that was what they used for
their distribution. Eventually the phone company got onto what they
were doing and connected large capacitors across the pairs, which put
an end to their scheme.
