I have no idea, but I do know that in the case of wired computer-network 
lines, they must all be terminated in the characteristic impedance of the line 
itself.

For instance, if 50 ohm coax is used for those wired computer-networks, the 
terminating devices are usually BNCs with a 50 ohm resistor built into them. I 
still have several of those here in my stash.
