Hi! I'm sure the Chase and Bank One have switched over to digital HF
networks moving their financial data around.

You think so? I don't. I'm guessing that their data moves via phone
lines. If the phone lines aren't there, it'll move when there are phone
lines.

My guess is that their mainframe stuff uses buried fiber optic
circuits. In 1988 I got the nickel tour of the then-new Union
Pacific Railroad Control Center in Omaha. The Comm chief actually
showed me where two circuits emerged on two sides of the building,
one running via St. Louis and the other running via Kansas City. In
vital data circuits, redundancy is the name of the game.

I can understand your confusion, Brian. The power lines carry
electricity. The telephone lines carry telephone conversations. The gas
lines carry natural gas.

Ah!! Good point.
