1 SDO Emergency Services Workshop Indiana Wireless Direct Network Byron Smith

2 Introductions Indiana Wireless Advisory Board collects and distributes money portfolio limited to wireless 911 INdigital Telecom Contractor for Indiana Wireless Direct Project Byron Smith Architect and Head Developer

3 Board Movers and Shakers improving wireless E911 overseen by the State Treasurer Tim Berry, outgoing Treasurer Richard Mourdock, Treasurer elect Ken Lowden - ENP, Executive Director

4 INdigital Telecom Privately held Indiana Corporation Owned by 11 Independent Telephone Companies Facilities-based CLEC operating in Northeastern Indiana A stakeholder in Indiana Fiber Network Won the Indiana Wireless Advisory Board’s IWDN project in a competition

5 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

6 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.”

7 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)

8 Original Wireless Network Wireless MSC to ILEC Selective Router Facilities MSC ILEC SR MSC (32 MSCs)(17 ILEC SRs) (etc.)

9 Crossroads trunk consolidation Crossroads Wireless MSC to ILEC SR Facilities MSC SR ILEC SR New Selective routers b) SS7 links (32 MSCs) MSC (15 ILEC SRs)

10 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. Current info at:

11 IN911 network All IP network Meets NENA requirements for “NG 911” IP infrastructure: Private, firewalled Redundant Diverse Monitored

12 IN911 Network Components PSAP Secure Private Diverse Redundant IP Network Gateway MSC SR SS7 links ALI DB Admin ALI DB Gateway PSAP

13 IN911 Backbone Dedicated STS-1 on diverse SONET fiber ring Dedicated CISCO “RPR” ring 16 “POP”s on ring, at least one POP in every LATA No single-point of failure Leased from Indiana Fiber Network

14 IN911 Backbone POP detail IFN POP Site Detail SONET Fiber RPR Ring Cisco 3745 IP router Cisco 3745 IP router 100 Meg Ethernet PSAP DS1 DS1 Chain (This equipment at IFN connection site) (start/end of additional DS1 PSAP chain.) DS1

15 IN911 PSAP detail (typical) Typical IN911 PSAP terminations Cisco 28xx Cisco 28xx VoIP PSAP equip Ethernet switch Dual DS1 connections to IN911 network Traditional ANI/ALI controller VoIP PSAP equipment or ethernet CAMA trunks ALI data PSAP site equipment

16 Real-world PSAP installation

17 Detractor’s view of installation

18 IN911 Status map Real time, actual network status Shows DS1s leaving backbone POP and interconnecting PSAPs A mesh architecture Economy: Redundancy at cost of less then 1.5 DS1s per PSAP, DS1 distance average width of county

19 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

20 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!


22 We have come a long way, baby!

23 Graphic visualization of live traffic And from recent history:

24 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.

25 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

26 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

27 A metro area PSAP

28 A rural PSAP

29 Which PSAP has what they need?

30 Where Technology Happens

31 wireless calls in ALIviewer

32 wireline calls in ALIviewer

33 Q&A 260-469-2010
