Legacy Network
The current 911 infrastructure is based on point
to point voice grade circuits using CAMA
signaling. Customer location information is
delivered to the PSAP via the Qwest ALI data
based managed by Intrado

ALI-M Migration

• The ALI-M migration replace the current ALISR
  with ALI-M
• Distribution Points are replaced with Terminal
  Servers
• 56k is replaced with CO LAN, T1s and the Intrado
  WAN

IP to ALI

• IP to ALI replaces the point to point data
  circuit with Qwest provided TCP/IP over Frame
  Relay or iQ Private Port
• 202T modems are replace with Cisco 2811 routers
• The PSAP connects directly to the ALI-Ms
  eliminating the Terminal Servers
• XML Bridge is installed at the PSAP to manage the
  XML to ASCII conversion

Next Gen 911 Layer 1

• Next Gen 911 Layer 1 Re-homes the EM trunks and
  converts from CAMA to IP.
• The IP Selective Router is introduced to perform
  the CAMA to IP conversion
• CAMA Trunk are re-homed to the IP SR
• iQ Private Port is used to deliver the voice and
  ALI to the PSAP
• A PSAP Gateway Module is installed at the PSAP to
  convert the IP to CAMA

So what now?
FEDERAL
LOCAL
STATE

• Responsible for managing statewide IP network and
  the delivery of 9-1-1 calls to PSAPs
• Strong State 9-1-1 Coordination
• Statewide 9-1-1 Management/Boards (for all
  aspects of 9-1-1)
• Management and Guidance
• Manage technical interface and requirements for
  PSAPs to access state IP network
• Coordinate all efforts and stakeholders within
  state
• Minimize need for PSAPs to understand all
  technology advancements and individual service
  provider capabilities
• Knowledge broker for local government

• Primary responsibility should be to receive calls
  and provide response to calls (assurance of
  service delivery)
• 9-1-1 service remains locally managed and
  controlled
• Responsible for much less technology and vendor
  relationship management
• Develop and Maintain Local Data
• Local PSAP authorities have best knowledge of
  local Information and Infrastructure

• Develop guidelines, standardized system
  interfaces and provide funding for a national IP
  emergency services infrastructure (state
  coordinated)
• Including, but not limited to 9-1-1 (shared IP
  infrastructure economies of scale created)
• Guidelines should be provided for states to meet
  (not specific solutions)
• Funding requirements need to be tied to these
  guidelines
• Analogous to federal highway model
• An entity within federal government needs to
  coordinate all federal activity (should
  be/include National 9-1-1 ICO)

No, I mean what now for Colorado?

• Get your priorities straight
• In practical terms what does NG9-1-1 mean to you?
• More bandwidth
• Better routing solutions
• Greater interoperability
• Fewer points of connection
• Decide where you want to start
• EM
• ES
• SR
• CPE
• EO/MSC
• Decide if you stand alone
• The current model (BESP) only works when everyone
  participates
• Decide how are you going to pay for it
• You will spend more, a lot more
