I have a situation where I want to have two extensions carried by three
wires. I have a four-wire cable going between floors, with two of the
wires shorted together. It would be much easier to use the existing
cable than to rip it out and string a new one.
Is it possible to make the two lines share a wire, is there a common
ground? If it is possible, which should I make common. I know there
is something called tip and ring, but how do I tell one from another?
Please send mail directly to me, I'll summarize. Thanks.
