[GreenKeys] Off topic but interesting - ADT Security

That reminds me of a "semantic" problem with the name of a department at
Amtrak.

Communications and Signals (C&S) is responsible for, as one would guess,
the communications and signal facilities of the railroad.  (In Pennsylvania
Railroad days, this was called the Telegraph and Signals (T&S) department.)

The "sub-department" responsible for the "C" side was always referred to as
T&T for Telephone and Telegraph.  There were those who thought that the
designation was "dated."  I always said, however, that "Telegraph" can also
mean "Printing Telegraph" which, in 1978-79 still meant 5 bit code: a
digital entity.  Of course, as that was phased out, it was replaced with
other forms of digital communications that just use a different number of
bits at higher speeds.  T&T sounds fine to me!
