Totally off topic, but...
In another world, I am an antique telephone collector and phone "switcher".
I have 11,700 Bell System Practices documents in PDF in stock, so for hack value I just searched them all with Acrobat for "octothorpe".
I got just one hit:
Bellcore Practice RB 241-120-040, July 1984. "Measurement and Data Management... DMS-10"
Of course the DMS-10 is a Canadian switch, so they would probably use
the Canadian term current at the time. But certainly Nortel borrowed
that from 1960s AT&T usage.
Are we off-topic yet?
