If it's not twisted pair, it will be SLOW...maybe about 10-30Mb, because to go any faster, the twists are all the "magic" (magnetic induction). But, it will pass data, just at old school data rates.But, it will work, unless there is heavy EM interference in the shaft. Any way to use wireless access points to do what you want?

In which case, use the actual telephone connection in the elevator and forget the electricians wires. The PC in the cab is "guest," the one in the control room is "host."What's the big deal here, really?

If the cable is good enough you may get a connection. At this length untwisited it may be very prone to electrical interference.

The pairs are twisted at different amounts so transmision reaches the other side at the same time. Go wireless or use a repeater to achive your objective. d;o)
