9-1-1 Next Generation September, 2007

The three-digit telephone number "9-1-1" has been
designated as the "Universal Emergency Number."
It is intended as a nationwide telephone number
and gives the public fast and easy access to a
Public Safety Answering Point (PSAP).

1957, National Association of Fire Chiefs
recommended use of a single number for reporting
fires.
In the early 1970s, ATT develops "selective call
routing."
1998, Seattle, Qwest delivers the first Enhance
Wireless 9-1-1
2005, VoIP E9-1-1
February 16, 1968, Senator Rankin Fite completed
the first 9-1-1 call made in the United States in
Haleyville, Alabama.
1987, 50 of the US population had access to 9-1-1
2003, 96 of the geographic US is covered by some
type of 9-1-1.
30 years after the introduction of Enhanced
9-1-1, the service remains essentially unchanged.

Fundamental and significant change in the
communications industry is driving the need for
Public Safety solutions that accommodate the many
new ways that emergency services can be requested
and the response provided.

• Basic 911 A direct connection between a dial tone
  office and the PSAP
• Enhanced 911 Calls are routed based on location
  and calling party information is displayed
  (ALI)
• Wireless 911
• Phase 0 Calls are directed to a 10 digit
  administrative number at the PSAP
• Phase I Calls are routed based on the cell site
  (Antenna) location
• Phase II Calls are routed based on the callers
  location (XY)
• VoIP (Voice over the Internet Protocol)
• I1 Calls are directed to a 10 digit
  administrative number at the PSAP
• I2 Calls are routed based on the callers
  location (XY) over TDM
• I3 Calls are routed based on the callers
  location (XY) over VoIP
• Telematics, ACN OnStar, Automatic Crash
  Notification
• Text Devices Instant messaging to the PSAP
• PDAs, Blackberry
• Satellite Phones
• AirPhone
• Medical devices

A new Emergency Services Network will bridge
together PSAPs, emergency service providers,
jurisdictional oversight, management functions
and others. 

• The current solution set is constrained by the
  legacy design
• Analog circuit switching
• In-band multi-frequency (MF) CAMA signaling
• Limited messaging capability
• Fixed point-to-point communication
• Span of control is diminishing
• PSAP funding mechanisms
• Current models are breaking or are broken
• Networks and systems must be constructed to
  support the
• Higher levels of interaction
• Managed situational intelligence
• Coordinated response
• Comprehensive communication sets
• Service Provider model complexity

Controlled access points or gateways will exist
where entities do not reside in E911 today.
