VoIP Adopts the Wireless E9-1-1 Model 5
Requirements for E9-1-1 Requirements for a proper E9-1-1 call: • Must know location of caller • Must use caller location to route call • The US has over 8000 Public Safety Answering Points (PSAPs) • PSAPs typically cover metropolitan areas or counties • PSAPs are Call Centers which dispatch Emergency Services • Must deliver caller location • Call Centers can automatically receive location information • For wireline & VoIP, street address information is delivered • For wireless, latitude/longitude information is delivered 1 [Location] + 2 [Routing] + 3[Delivery] = Full E9-1-1! 6

The Current VoIP E9-1-1 Models 9
VoIP Presents E9-1-1 Challenge • Voice over IP (VoIP) • Voice transmitted as data over IP transport • Three broad categories of service: • Static VoIP: to the home as a wireline replacement • Nomadic VoIP: person stops in different places • Mobile VoIP: continuous movement within VoIP network • Challenges: • [1] How to locate? • [2] How route? • [3] How deliver? 1 2 3 10
Phased Approach for VoIP E9-1-1 • I1 – routing to PSAP administrative line • This is “Basic” 9-1-1 – not “Enhanced” E9-1-1 • Requires geospatial boundary maps for PSAPs nationwide • I2 – use existing E9-1-1 infrastructure • True “Enhanced” E9-1-1 • Requires same as I1 and also access to Selective Routers • I3 – use VoIP in the end-to-end delivery model • True “Enhanced” E9-1-1 • Requires boundary maps but NOT selective routers • PSAP uses VoIP in their response systems • VoIP call the whole way 11

The Toughest VoIP Challenge: Location 14
Automatic Location: Port Discovery • Port identification & discovery • System identifies ports in use • System interrogates devices attached to ports • Port mapped to telecom identifier • Administrator can map port to a specific location • Done for PBX systems today • Helps business meet FCC E9-1-1 MLTS requirements • Updates submitted daily – activated w/in 48 hours • VoIP implementations will change more rapidly • 48-hour delays will impact progress on MLTS issues • Excellent for Enterprise applications 15
Automatic Location: Triangulation • WiFi triangulation techniques • Triangulates on attached devices • System interrogates devices attached to ports • Interacts w/ client software on device • Accuracy demonstrated within 3 to 5 meters • Excellent for enterprise applications 16
Automatic Location: GPS • GPS Triangulation Techniques • Integrated into WiFi device • Interacts with visible satellites for multi-point triangulation • Same technology as in current wireless handsets • Accuracy under 5 meters in many scenarios • Excellent for consumer applications 17
Automatic Location: TV-GPS • TV-GPS Triangulation Techniques • Integrated into WiFi device • Interacts with TV towers for multi-point triangulation • Same technology • With three connections, can triangulate within 1 meter • Excellent for consumer and enterprise applications 18
Automatic Location: WiFi Mapping • Mapping of WiFi Hot Spots • Handset identifies WiFi connection point • Over 70 major metropolitan areas mapped • Thin client communicates IP address to Mapping Server • When 9-1-1 is dialed, TCS interrogates Mapping Server • Accuracy within 30 meters or better • Currently able to provide live demonstrations • Excellent for consumer or enterprise applications 19

You May Be Unprotected!! • Public Safety is demanding E9-1-1 • The customer base expects it • The FCC has mandated it • Regulations protect Competitive LECs (CLECs) • Most states provide liability protection • Extends to wireline, wireless, and CLEC • Not all VoIP Service Providers are CLECs • Some wish to avoid the regulatory environment • Unfortunately, they miss the regulatory protections 23
Solutions Being Tested and Deployed 24
Applying Wireless Mobility to VoIP VoIP Carriers • Preferred vendor for Vonage (largest VoIP Service Provider – VSP) • Partner with Level(3) (largest VoIP Backbone Provider) VoIP Solutions Being Deployed • I1 solution provided today • Calls can be primary-routed to Administrative Lines • Calls can be primary-routed to TCS Response Center (RC) • TCS RC can deliver calls to Administrative Lines • TCS RC can deliver calls directly to First Responders (Fire, Police, Ambulance) • I2 Calls successfully completed at hundreds of PSAPs nationwide • Routing Instructions provided to VSP call server • Call-back number and Registered Location automatically delivered to PSAP PSAP Outreach Efforts • Education & information exchange w/ 3000+ PSAPs nationwide 25
