That’s what I was thinking. Back in the day, we had a 10Mbit hub that we ran all printers through, leaving the nice 100Mbit switch for workstations. Shortly after I started, I noticed one of the workstation cables had a bright green zip tie on it. When I asked our network manager why, he said it was a special person upstairs, whom I’d soon come to know well, who occasionally needed to be patched into the printer hub.
Pin 1,2,3,6 is connected, it can be used with 100Mbit/s ethernet.
(I once met with wall sockets wired like that – each Cat5e cable was splitted in two 4-wire groups, and each group was wired with pin 1236 of the two ends of socket. It happily runs as 100Mbit/s

Possibly the start of a crossover cable? Best I can tell…
10mb/s 😀 That’s it. Probably it was a cable from a DSL router in which 1mb/s is enough
millibits per second?
10 Meg half duplex. Early days of Ethernet. Still scares me to this day.
voip. voice only.
I figured that was the cable the IT guy used to hook who ever really pissed him off to the network. ;-}

Its a phone cable.

It’s fairly uncommon, but there are systems that use standard RJ45 cables just to transfer electricity/serial data.
