Be cautious about using the physically smaller RJ11/12 plugs in RJ45
sockets. Sometimes the plugs can screw up the flexible pins/wires in
the sockets because the shoulder of the plug doesn't quite fit
comfortably. Better to make your patch cords with RJ45's.

As for CAT 5 and Ethernet, you must use CAT 5 for 100 MB Enet; you
might get away with short stretches of plain old bell wire for 10MB Enet.

I plan on installing a VOIP setup in my house.

The problem is that the phone wiring that enters the house is 8 conductor
and is hardwired to the phone distribution center. So, I figure I can break
into that incoming line and install a couple of cat5 8 conductor female
plugs on the two severed ends and can use a cat5 patch cord to connect them
if I ever want to go back to the teleco. But, that would only happen if I
sell the house.

The question I have is: Can I plug in a normal rj11 modular plug (coming
from the modem) into the female rj45 jack that I'll be installing upstream
from the distribution center and expect those 4 conductors in the plug to be
aligned with the appropriate conductors in the rj45 jack? The phone modem
only has rj11 plugs.


BTW-I know I'll only be able to hook up one phone (an expandable wireless
system) to this setup. I just want to make my setup easy to undo when I
move.
