Frank,
A PBX is a Private Branch Exchange.
It is used inside commercial buildings to distribute phone calls, with each phone being an extension of the main phone, I think.

Nasty indeed. Shorting or crossing the actual phone lines wouldn't cause this.

The miswiring was most probably either:

(a) 120 or 240V AC power connected to the wrong points, or

(b) a 50V battery supply incorrectly wired and no proper fusing in place.
