Presentation Agenda PSAP Console Technology- Legacy 11/15/2018 Presentation Agenda PSAP Console Technology- Legacy PSAP Console Technology- Today Wide Area Trunked Radio System Overview High Level Presentation! I will do my best to stay out of acronym hell! Disclaimer Depictions noted are for demonstration purposes only and do not reflect any specific system design. Presenter is not responsible for errors or omissions in training materials

Dispatch Radio Console 11/15/2018 Dispatch Radio Console If you are responsible for procuring a replacement radio console, it is the objective of this presentation to help you understand the general technology of your system today This knowledge base will provide a recognition of what technologies a future console system is capable of leveraging

Dispatch Radio Console-101 11/15/2018 Dispatch Radio Console-101 Do you know how your radio console works? A console is NOT “FM” (Freakin’ Magic)!

Dispatch Radio Console 11/15/2018 Dispatch Radio Console A console is NOT a radio!

Dispatch Radio Console-Legacy 11/15/2018 Dispatch Radio Console-Legacy Basic design-Two building blocks Dispatch Position-Typical GUI (PC w/Monitor) or Buttons/LED’s (Legacy design) Interface Box Microphone, speakers (Select/Unselect, Monitor 1-X) headset interfaces, footswitch etc

Dispatch Radio Console Legacy 11/15/2018 Dispatch Radio Console Legacy Backroom equipment-Typical Cards which communicate with operator (Dispatch) position Typically one card per position Cards which communicate with a circuit Typically one card per radio “channel” Circuit is usually connected to a radio/base station/repeater at a remote location (EX tower)

Circuit- This is important! 11/15/2018 Circuit- This is important! IP MUX OR OR PSAP Backroom P25 Conventional Base Radio OR OR Leased Circuit

Dispatch Radio Console 11/15/2018 Dispatch Radio Console Q&A Who has “digital” (P25) radio channels into their PSAP? Of these PSAP’s, which ones leverage the advanced features of P25 (Radio ID, Emergency, etc.)? If not, why? Which PSAP’s back up their neighbor for radio communications? One of the possible reasons is the limitations of the CIRCUIT!

11/15/2018 We are building a foundation of knowledge, so be patient! Questions…so far?

Dispatch Radio Console-Today 11/15/2018 Dispatch Radio Console-Today Basic design-Two building blocks Dispatch Position-Typical GUI (PC w/Monitor) Interface Box Microphone, speakers (Select/Unselect, Monitor 1-X) headset interfaces, footswitch etc Dispatch interface relatively unchanged from “Legacy” BUT What really matters is “Beneath the hood” In this case, the backroom!

Dispatch Radio Console Today 11/15/2018 Dispatch Radio Console Today Backroom equipment-Circuit Based Typical Equipment may have a different look, but it will still have modules or interfaces to legacy circuits only May have gateways or Radio over IP interfaces, but they still connect to the same old radio circuits The equipment will connect to a trunked radio system via wireless radios only (Control stations) Backroom equipment is NOT capable of a network connection to RFSS (RF Sub System, also referred to as the “Core”)

Dispatch Radio Console Today 11/15/2018 Dispatch Radio Console Today Backroom equipment-Network Based Typical Will look very similar to a computer network rack. An assembly of servers, switches and gateways. Backroom equipment connections to RFSS(RR Sub System) via dual network connections (redundancy) IE Patch Cables Gateways are utilized to connect to Legacy radios Any controls stations utilized are for backup or recording purposes Basically network equipment with backwards capability to Legacy circuits

Dispatch Radio Console to wide area communications network 11/15/2018 Dispatch Radio Console to wide area communications network Two Types Wireless subscriber-unit interface Wired RFSS Interface (Network) Wireless Wired RFSS

Dispatch Radio Console to wide area communications network 11/15/2018 Dispatch Radio Console to wide area communications network Wireless Description Architecture based in circuit technology IE Backroom equipment similar to Legacy console systems Compatible with legacy conventional radio systems Does not allow for supervisory dispatch (dispatch interrupt) control of wireless radio resources Dispatch same priority level as any field radio PSAP Redundancy with neighbors limited (Same as today) Encryption limited on a per channel talkpath basis Expanding qty of talkpaths via wireless requires additional hardware and installation Radio w/antenna system, connectivity, interface port/gateways, etc Not CSSI Capable (P25 Console Sub System Interface) Wireless

Dispatch Radio Console to wide area communications network 11/15/2018 Dispatch Radio Console to wide area communications network Wired RFSS Description Architecture based in network technology IE Backroom equipment consists of servers, switches and gateways Backward compatible with legacy conventional radio systems Allows for supervisory dispatch (dispatch interrupt) control of all trunked radio resources PSAP Redundancy with neighbors limited by permissions and agreements, not technology Access to any radio resources network connected to RFSS (Conventional or Trunked) Encryption is end to end (IE Encrypted Audio from DISPATCH position to field unit) Expanding qty of talkpaths (On RFSS) via programming No additional hardware require CSSI Capable (P25 Console Sub System Interface) Wired RFSS

NOW TO TIE IT ALL TOGETHER! 11/15/2018 NOW TO TIE IT ALL TOGETHER! A single trunked radio site has extra capabilities and resiliency over a conventional infrastructure, but the real benefits for public safety are realized when trunked communications sites and PSAP’s are connected (Networked together).

Dispatch Radio Consoles and Trunking 11/15/2018 Dispatch Radio Consoles and Trunking Fact or Fallacy? I need to replace my radio console to talk on a trunked radio system! False If (Name your agency) adopt trunking, we will not be able to talk to my neighbors! I cannot page (tone and voice) over a trunked system! True

11/15/2018 Questions?

Televate User Study-Summary 11/15/2018 Televate User Study-Summary Recommended Trunked System Buildout VHF and 700/800 MHZ Standards Based System (P25) Not proprietary (per TIA Standards) Depicted direct console interfaces in concept diagrams

Televate User Study-Summary 11/15/2018 Televate User Study-Summary What the study didn’t cover Detailed Design and Review of system Phase 1or Phase 2 P25? Phase 1-FDMA Based Conventional and Trunked Operation Analog, Digital P25, or Mixed Mode Phase 2-TDMA Based Trunked Operation Only Backward Compatible with all Phase 1 operations

Console procurement questions for your vendor? 11/15/2018 Console procurement questions for your vendor? Is console (X) capable of dispatcher interrupt? (Dispatch supervisory control) Is console (X) capable of a wired or CSSI connection to a RFSS core? Is console (X) capable of a wired or CSSI connection to a P25 Phase 2 RFSS core? Is console (X) capable of emergency radio ID on a P25 trunked system? How does console (X) handle encryption? End to end? Per channel/talkgroup?

PSAP Console-What to do? 11/15/2018 PSAP Console-What to do? Console choice is not mandated! Window of opportunity 12 out of 22 ND PSAP’s own dispatch equipment reaching end of life. Measure twice, procure ONCE! Educate yourself and your local vendors Keep an eye on big picture of public safety communications in ND (Today and Future) Take the “long view” IE Do not simply replace what you currently have
