size=2>A, B, C and D are valid DTMF "digits" with their own tones... imagine
another column of four more keys on the right hand side of your existing keypad
with A - D running top to bottom. This column has its own tone in the
"Dual-Tone Multiple Frequency" setup, and uses the same row tone as that used by
the digits you are already familiar with, combined to make a dual-tone like
every other digit.</FONT></SPAN></DIV>

size=2>They were principally used on the U.S. DOD AUTOVON private telephone
network to signal priority. A call preceded by an A (flash override, the
highest priority) would preempt any calls on congested trunks with lower
priorities. The remaining three digits represented lower levels of
priority, and a call with no digits preceding was deemed "routine" with the
lowest priority of all. Telephone carriers companies used to also use them
for various signal indications back when analog trunks were still fairly
prevalent.</FONT></SPAN></DIV>
