Look in the telco vault of any large building old enough to have POTS lines
coming in on real copper -- there'll be huge fuse panels, one fuse for each
line; same technology was used for T1 and T3 circuits as well, though
probably with different fuses.  I can't specify exactly what type of fuses
or panels you would buy, as I've religiously avoided inter-building copper
myself.

Fiber good, copper bad.  Move along :)
