Hi,
 I have a 4-pair CAT-5 cable between two floors in my house. I was
wondering if I can use this 4-pair cable instead of two CAT-5 cables to
connect to a switch I have at one location.
The toplogy is:

                       PC3_
PC1\                     __ \
   >====4-pair=cable===<  |^^^^^^^^|
PC2/                     \_| SWITCH |
                    PC4___|________|
Can this work?

you need to connect two rj45 connectors on each side of the cable.

one pair to pins 1,2 of connectors A and B (A from one side of the line, 
B on the other)
one pair to pins 3,6 of connectors A and B
one pair to pins 1,2 of connectors C and D
one pair to pins 3,6 of connectors C and D

it should work if the cable is not too long

cheers,
erez.
