The Beginning of 911 in America
ITU-T
o

o
o
In 1958, U.S. Congress called for a
universal emergency number.
In 1968, AT&T and the FCC announced that
911 would be the nationwide emergency
number.
On February 16, 1968, the first call was
made from Haleyville, Alabama.
Forty years later in 1998, U.S. Congress
passed the 911 Act.

One such method is 3-Way Conference
Calling.
The Commercial Call Center issues a
command to the vehicle’s cell phone to set
up a 3-way conference call through the
local cellular switch (MSC).
This allows direct vehicle-local dialing of
the emergency number as determined by
local public safety authorities.
