The Nevada Western stuff we used in the 1980s was probably vendor

to swap out the modular cable with one that was made "upside down" and
turning it into a null modem. More directly, I don't think the 6P6C
pinout was symmetrical (there was only one ground wire, not two in the
middle).
You still could get adapters that routed eight terminal sessions over
a 25-pair cable with Telco 50-pin ends, and you could still use telco
punchdown blocks, but the device ends weren't wired like the later
Cisco stuff was.

Are any of those other pinouts
"standard"? I've found the material in
several of these Wikipedia articles to be very incomplete.
Well, for certain values of "standard", perhaps.
