A bit about me
  Came to Telecom in 1992 from
     academia
  MS from Purdue (Computer Science),
     additional graduate work University
     of Illinois at Chicago
  Recruited by Marc Linsner (and others)
     to Sprint, 15 years in public safety
Indiana Wireless Direct Project
  Board unhappy with performance and
     cost of “grafted-on” wireless 911
     solution
  Board was aware of the Kansas city
     area MARC project
  Hired L. Robert Kimball & Associates as
     consultants to do “wireless direct.”
History of the project
  2003 Kimball “Feasibility study”
  2004 RFI, responses, and competition
  2005 Contract negotiations and startup
  2006 Part I – “Crossroads” project
     (SS7 trunking and consolidation)
  2007 Part II – “IN911” project
     (IP network to PSAPs)

Stats and Status
  IN911 presently carries 25% of the
  daily traffic (1500 calls / day)
  IN911 is in the “back room” of PSAPs in
  63 of the 92 counties
  IN911 currently delivers voice and ANI
  to ~ 40 PSAPs
  IN911 currently delivers ALI data to ~
  25 PSAPs
IN911 protocols
  IP: TCP, UDP, EIRGP, BGP, others
  SIP, RTP, etc.
  CPL
  XML, HTTP, etc
  SS7: TCAP, AIN, ISUP
  And “traditional” CAMA/Enhanced MF,
  PAM, E2+, and RS-232 serial data!
We have come a long way, baby!

   And from recent history:
 http://www.quake.in911.net/
The bottom line…
  nearly a million calls in 2006
  over two million calls in 2007
  average 6000 calls every 24 hours
  improved call delivery speed, accuracy,
  redundancy, and lower cost
  an infrastructure we can build on for
  the future.
Transitioning to Next Generation

  Moving beyond 9.6k data and MF
  signaling
  Creating redundancy, high availability
  Road mapping the future
      text messages to 911
      pictures to 911
      OnStar and ATX crash information to 911
Delivering expanded data
  Forklift upgrades aren’t an option
  Data delivery improvements
  offer a lower cost path to the future
  We want to get more information,
  and more accurate information on
  the dispatch screen
