My understanding is that the "c-tone" is the same as that generated by|
the "C" button of the A-B-C-D/FO-F-I-P column found on old DoD
precedence-equipped touch-tone AUTOVON phones. The C or I (for
"Immediate" precedence) button delivers a DTMF pair of 852 and 1633
KHz. Ping me off net for some AUTOVON phone pics.
