Not to mention that if you need to pass cables through tiny holes in walls, you do need to be able to put a plug or socket onto a wire. That probably requires a tool (I'm yet to see a connector that could be easily done without one). > One thing I've wondered: On what basis should one choose between > using EIA 568A and EIA 568B?

I wonder if the way some cables are formed makes it easier to wire it one way or another? Hand wrangling the wires into the right place to crimp on a plug can be a right pain. You've got untangle wires, cross some over others, and get them all to go into the plug the same distance. It would have been a lot easier to do that if they'd come up with a wiring arrangement different from the current specs. i.e. A pair on 1 & 2, the next on 3 & 4, the next on 5 & 6, the last on 7 & 8, instead of having the break apart pairs and straddle others. I seriously doubt that would have degraded noise rejection. -- (Currently running FC4, occasionally trying FC5.) Don't send private replies to my address, the mailbox is ignored.
