9-1-1Next 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.

February 16, 1968, Senator Rankin Fite completed the first 9-1-1 call made in the United

States in Haleyville, Alabama.

In the early 1970s, AT&T develops "selective call

routing."

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.

1998, Seattle, Qwest delivers the first Enhance

Wireless 9-1-1

1950 1960 1970 1980 1990 2000

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• Video

• 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

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

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