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
• 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 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
