I meant a cable-extender that lets two Cat-[456] cables become one longer cable (aka an RJ-45 F-F gender-changer, aka "RJ45 Joiner") would allow my pocket 10baseT/100BaseT signal checker to check if a cable plugged into a known good jack was good. (I don't think it supports newer 1000baseT ... but newer ones might.)
