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

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?

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

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
16
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
17
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
18
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
19
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

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
