There were lower levels of priority that you could also use, but "flash" was the top one that I heard about.

The four buttons on the "1633" row of an AUTOVON telephone are labeled P, I, F, and FO for Priority, Immediate, Flash, and Flash-Override. The fifth (normal) level is of course routine, with no priority code attached.

And those levels appear as the TOS bits in RFC 791.... --Steven M. Bellovin, http://www.cs.columbia.edu/~smb
