CAD-to-CAD Interface

The Base Building Block for Interoperability


In today’s public safety world there is an increasing awareness about the need for Interoperability between disparate CAD systems, and it is becoming a vital component of a PSAP’s operations. In today’s increasingly “connected” world, this requirement is growing. The pressure to implement this capability comes from a multitude of sources: the increasing use of sophisticated communications devices; public awareness of these capabilities and demand for public safety agencies to incorporate capabilities in their operations; the increasing usage of the various forms of social media such as Twitter and YouTube; the implementation of NG911; the need to coordinate multiple jurisdictional efforts during terrorist activities; to name some of the more significant drivers. This is especially true when it comes to a PSAP’s dispatching functions and the need for CAD-to-CAD communications. These forces are driving the demand for increased sophistication in the use of CAD information, which in turn is requiring additional technical systems to assist PSAPs in disseminating incident information to other jurisdictions.


This communications capability is defined by The Department of Homeland Security as “Communications Interoperability – “the ability of public safety agencies to talk across disciplines and jurisdictions via radio communications and systems, exchanging voice and/or data with one another on demand, in real time, when needed, and as authorized.” Further, the Department of Homeland Security has published a paper called the Interoperability Continuum. There are 5 elements that comprise the Continuum and they are:

  • Governance
  • Standard Operating Procedures
  • Technology
  • Training & Exercises
  • Usage


When we look at Interoperability in its fullest sense, the core component needed to achieve this ability is technology. Technology within the Continuum is defined to include a number of different elements including Swap Radios, Gateways, Shared Channels, Proprietary Shared Systems, and Standards-based Shared Systems. CAD-to-CAD Interfaces are based on Standards Based Shared Systems and are a necessity to achieve an optimum level of Interoperability.


The primary function of communications interoperability is CAD-to-CAD communication. Last year, Winbourne Consulting published a white paper looking at the various types of CAD-to-CAD interfaces. The paper discussed 4 different levels of communications.

  1. Consolidation Model – Multiple PSAP’s join together to form one large center and utilize a single CAD (Computer Aided Dispatch) System;
  2. Point-to-Point Interface Model – Two PSAP’s with different CAD vendors’ contract each CAD vendor to create an interface between the two CAD systems;
  3. Message Broker Model – Two or more PSAP’s with different CAD vendors’ contract with a third party Vendor to create a rudimentary hub that acts as a transfer agent to deliver basic CAD information to each participating CAD system; and
  4. Intelligent Hub Model - Two or more PSAP’s with different CAD vendors’, or the same CAD vendor contract with a third party Vendor to create an intelligent hub that acts as a transfer agent to deliver complex and configurable CAD information between all participating CAD systems. When all the pros and cons are evaluated, it becomes readily apparent that an intelligent Hub is required in order to function in any sort of interoperability mode.


During this past year, Winbourne Consulting has been working with various public safety organizations including a major northeastern university, one of the nation’s largest metropolitan areas fire departments, and jurisdictions in an upper mid-western state to define CAD to CAD requirements and to implement an interoperable solution. In working with these and other clients, it was found that the most effective model to implement even a basic form of Interoperability was the Intelligent Hub Model.


As a result of these projects, it became readily apparent that a stepped approach was needed to address the varying needs of agencies. In that stepped approach there are 3 basic CAD information sharing models:

  1. Level 1 – Information Sharing which is a real-time, view-only model that is fed by the participating agencies’ CAD Systems
  2. Level 2 – Interactive Facilitation – model with ability for agencies to interactively work as a team in developing responses to a specific incident
  3. Level 3 - Full seamless operation with multiple CAD Systems where responses to designated incidents are automatically initiated and managed by the designated agency. * See Note 2


Additionally, Winbourne has identified a number of functional specifications as being essential to achieve CAD-to-CAD Interoperability. These include the ability to:

  • Subscribe to the current status, time stamps, and location of resources and assets from connected CAD systems
  • Publish in real-time the status, time stamps, and location of resources and assets with connected CAD systems as authorized
  • Provide a centralized view of current status, location and time stamps of resources and assets from all connected CAD systems
  • Enable transfer, sharing, and ongoing updates of incident information between connected CAD systems as authorized
  • Publish and subscribe to requests to share resources and assets between connected CAD systems
  • Acknowledge the delivery of a request to share resources and assets to a lending connected CAD system
  • Publish the approval or denial of a sharing request for resources and assets to the requesting connected CAD system
  • Support subscribing and publishing of supplemental information of incident narrative between connected CAD systems as authorized
  • Provide centralized filters and business rules to flexibly configure and automate mutual and automatic aid agreements, and other information and resource sharing policies and/or procedures between connected CAD systems
  • Provide a CAD-to-CAD information and resource sharing monitor to view the state of active shared incidents and resources
  • Provide regional situational awareness and a common operating picture for EOC and incident command functionality of all connected CAD systems as authorized


While an effective CAD-to-CAD interface is the foundation to Interoperability, the Department of Homeland Security has also emphasized the importance of developing clear business models of operational facets within the Interoperability Continuum.


“To drive progress along the five elements of the continuum and improve interoperability, public safety practitioners should observe the following principles:

  • Gain leadership commitment from all disciplines [Emergency Medical Services (EMS), Fire, Law Enforcement],
  • Foster collaboration across disciplines (EMS, Fire, Law Enforcement) through leadership support,
  • Interface with policy makers to gain leadership commitment and resource support,
  • Use interoperability solutions on a regular basis,
  • Plan and budget for ongoing updates to systems, procedures, and documentation, and
  • Ensure collaboration and coordination across all elements [Governance, Standard Operating Procedures (SOPs), Technology, Training/Exercises, Usage].


In addition to the technology aspects of the CAD-to-CAD Interoperability projects, Winbourne further worked with the various agencies involved to implement the operational aspects of the above outlined principles that are needed to achieve Interoperability.
