Some remarks have been made here on Telecom that the AUTOVON tone pad
frequencies are different than those generated on Touch-Tone pads; they're
not.
Once, a few years ago, I talked an AT&T fellow who was replacing an AUTOVON
telephone (which had been dropped and then crushed by machinery moving
a big safe) out of the AUTOVON-style dial. I have it here; it makes
nice Touch-Tones which our telephone system gladly accepts. Nothing, of
course, happens when the right-hand column of keys is depressed, although
the frequencies are specified in the original Bell Telephone Touch-Tone
documentation (1633 Hz). The key caps on the telephone for the "P," "I,"
"F," "FO," "A," and "*" keys are removable (they pop off if you pry a
little bit).
And for those of you who really care, "P" means "Priority," "I" means
"Immediate" (and for those of you who have been around for a LONG time,
it used to mean "Operational Immediate," which is where the "OOOO" for
"Immediate" on your AUTODIN traffic came from), "F" means "Flash," and
"FO" means "Flash Override." Another precedence exists, the NCA precedence,
and is documented in the AUTODIN architecture documents, but it takes
direct operator intervention, and on AUTODIN is referred to as "VVVV."
Trivia.
1 2 3 FO
4 5 6 F
7 8 9 I
* 0 A P <- Note that the * is not a closed asterisk,
as on standard Touch-Tone phones, but an
open, five-pointed star, pointing up.
Enjoy.

Urge reading the ITT Radio Handbook. Historically, and probably on many telco
systems, operators used the non-DTMF to do what the older telco systems could
not easily prevent the phone hacker / blue-boxer from doing. /Old fone hacker/
