I can't believe no one is wiring to the ELAN standard. I recall one of their instructors saying it pre-dated T568A/B.
I shouldn't have joked earlier. After reterminating a dozen keypad connections for élan keypads today, my helper turned around and screwed up ten patch cables by completely reversing the solids and stripes for a standard 568A end.
