A bit about me
Came to Telecom in 1992 from academiaMS from Purdue (Computer Science),
additional graduate work University of Illinois at ChicagoRecruited 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 solutionBoard was aware of the Kansas city area MARC projectHired L. Robert Kimball & Associates as consultants to do “wireless direct.”
History of the project
2003 Kimball “Feasibility study” 2004 RFI, responses, and competition2005 Contract negotiations and startup2006 Part I – “Crossroads” project
(SS7 trunking and consolidation)2007 Part II – “IN911” project
(IP network to PSAPs)

Stats and Status• Indiana has:
• 11 wireless carriers
• 91 counties take 9-1-1 calls (Warren/Fountain are consolidated)
• 171 emergency communication centers (PSAPs)
• ~ 143 PSAPs take wireless 911 calls
• Crossroads handles 5000 – 7000 calls per day.

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 countiesIN911 currently delivers voice and ANI to ~ 40 PSAPsIN911 currently delivers ALI data to ~ 25 PSAPs
IN911 protocols
IP: TCP, UDP, EIRGP, BGP, othersSIP, RTP, etc.CPLXML, HTTP, etcSS7: TCAP, AIN, ISUPAnd “traditional” CAMA/Enhanced MF, PAM, E2+, and RS-232 serial data!
We have come a long way, baby!

The bottom line…
nearly a million calls in 2006over two million calls in 2007average 6000 calls every 24 hoursimproved call delivery speed, accuracy, redundancy, and lower costan infrastructure we can build on for the future.
Transitioning to Next Generation
Moving beyond 9.6k data and MF signalingCreating redundancy, high availabilityRoad 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 optionData delivery improvementsoffer a lower cost path to the futureWe want to get more information,and more accurate information onthe dispatch screen
