hook-flash
The hook-flash is used to communicate to the system that some sort of control
sequence will follow. It is accomplished by depressing the telephone hook switch
for an interval of greater than 50 milliseconds and less than 750 milliseconds (a
millisecond is 1/1000ths of a second, so 750 milliseconds is 3/4 of a second).
Some telephones have a flash button that accomplishes this task.
Note that your telephone system distinguishes between a hang-up, which is
longer than about three-quarters of a second, and a hook-flash, which is a short
depression of the hook switch.
The symbol
is used in this manual to indicate a hook-flash.

figured. Day and night mode can be changed from the telephone keypad and
