alt Hacker News> Ugh I don't really blame them there, that's really a dirty hack.
I certainly wouldn't do it today, but using two pair for a connection designed for two pair isn't a dirty hack, it's as designed.
Today, using 4 pair for 1G or more and a small switch on the host side to get more ports is probably a better plan.
Oh I wasn't aware of this actually being an intended usecase. And yes like the other poster said, pairing it with a phone infrastructure was more common (in the days before these went all IP of course).
It was a bit of my OCD being triggered as well. I love neat cabling at work (at home it is chaos funnily enough).
