3. Topics of Discussion History of 911 9-1-1 / E9-1-1 & NG9-1-1
GIS utilization in E9-1-1/NG9-1-1

4. History of 911
March 10, Alexander Graham Bell made the first call for help during testing of his gear, when he spilled battery acid on his clothing and said those famous words…”Watson, come here. I want you!”
July 8, Britain implements its 999 emergency telephone system serving police, fire and ems.
1957 The National Fire Chiefs reportedly suggest a single number for reporting fires
June 21, North America first 999 system was introduced in Winnipeg, Manitoba Canada

5. History of 911 <cont.>
Feb President Lyndon Johnson Commission on Law Enforcement and Administration of Justice issues its report recommending a single number to call, and that number should be used nationwide.
Jan 12, AT&T announces their designation of “911” as a universal number at a press conference in Wash DC.
Why 911? It came down to the fact that the digit 9 was the easiest to clear for access, because in many systems it was already clear; in others, equipment changes were small. The caller would then place the finger into the 1st position on the dial (rotary) and dial it two times. The outcome would be 9-1-1!

6. History of 911 <cont.>
2 pm, Feb 16, First 911 call was made in Haleyville, AL. using a “Bright Red” phone
1976 The city of Chicago, IL, claimed to have the nation’s first “Enhanced 911 system” of any major city. 6

7. History of 911 <cont.>
December Minneapolis-St. Paul implements an E911 system that was reportedly the first multi-county Enhanced system in the country. It served the seven surrounding counties. In 2006 this system was expanded to 8 counties and is still, geographically, the largest Enhanced 911 system in the country
March 31, The first phase 1 system (wireless calls display phone number and address or receiving tower) in the US in Allen County (Ind.)
April 1, Wireless carriers must be able to supply Phase I capability <callback number and receiving tower address.
October 1, Wireless carrier must be able to supply PSAPs with Phase II (Call back No., Lat/long of caller <accuracy dependant of technology>) Estimated today at over 268,000,000 US wireless subscribers (International Assoc of wireless telecommunications Industry) 7

March 31, 1998 The first phase 1 system (wireless calls display phone number and address or receiving tower) in the US in Allen County (Ind.)
2007 Minnesota is one of the leaders in transitioning into NG911, with NG911 pilot projects presently underway in the state. 8

9. PSAP (Public Safety Answering Point)
Basic Call Delivery
Voice/ANI
ALI Controller
ANI Controller
PSAP (Public Safety Answering Point)
ANI
Automatic Number Identification
Carrier End Office
Subscriber dials 911
PBX
Caller dials from either wireline or wireless and call is routed to end office switch.
End office switch sends voice and telephone number to PSAP
ALI Database
Current network not designed by user needs
Current system never intended to receive calls and data from wireless and VoIP technologies
Limited or no transfer capabilities between selective routers
Limited or no wireless transfer capabilities between selective routers
Does not provide transfer of caller notes and additional details associated with the call
Need database standardization between providers
Limited interoperability between PSAPs and other public safety agencies
Need to support new data types such as text messaging

ALI: Automatic Location Information
= Data Path
Caller dials from either wireline or wireless and call is routed to end office switch.
End office switch sends voice and telephone number (ANI) to the Selective Router.
Selective Router verifies routing instructions and sends Voice and ANI to correct Public Safety Answering Point (PSAP).
PSAP requests a bid for location information (ALI) from ALI Database.
ALI Database sends location information back to PSAP.
All happens within seconds.
Successful for more than 30 years but stretched to the limit!!

11. Next Generation 9-1-1 What is Next Generation 9-1-1 (NG9-1-1)
Fundamental objective of NG9-1-1 is interoperability of network and systems for voice, data and radio among emergency response agencies at a local, regional and national level
Set of coordinated applications on an IP internetwork that services multiple government functions and seamlessly interfaces voice and electronic data

17. GIS and Public Safety
GIS is used to determine caller locations….within the PSAP.
Next Gen – GIS plays an expanded role before the caller information gets to the PSAPs

18. Data Specifications Higher level of specifications
Data Synchronization
Data uniformity
As the use of GIS takes on an elevated use in the role of providing caller information the local jurisdictions will be required to provide and maintain a higher level of GIS data.
Additional data development may be required.

19. National Emergency Number Association NENA
Developing Data Synchronization guidelines
TDC/ODC Conference
Full day to GIS
They understand the importance of GIS as public safety moves into next gen
Workgroups
TDC/ODC – technical conference NENA is devoting a full day to GIS education

20. Questions???
As the use of GIS takes on an elevated use in the role of providing caller information the local jurisdictions will be required to provide and maintain a higher level of GIS data.

22. Minnesota Governor Council’s EPC NG911 Workgroup
Agenda
Educate Minnesota’s community on the efforts to standardize, on a national level, NG9-1-1 GIS Datasets
Provide guidance and data standards (per NENA) for GIS datasets that are to utilized for 9-1-1
Support and provide documentation to Minnesota’s communities for preparing GIS data for use in NG9-1-1
Reconciling centerlines with Master Street Address Guides (MSAG), and Emergency Service Zone (ESZ)
Synchronizing street centerlines with MSAG
Creation of Delta MSAGs
Develop support through various means to establish GIS datasets (geocodeable street centerlines, Emergency Service Zones) in Minnesota communities.
