NENA NG9-1-1 Go-To Handbook

__NUMBEREDHEADINGS__ = Executive Overview =

The purpose and scope of this document is to provide guidance to help 9-1-1 Authorities create a smooth, timely and efficient project management approach and transition plan to accomplish implementation of NG9-1-1. A considerable trove of written material and standards exists about the topic of NG9-1-1 within NENA, APCO, and other standards and industry organizations. An oft stated question is, “where does one start to gain a more complete understanding of all the materials?” This reference document can assist in answering this question. To navigate amongst the many NG9‑1‑1 reference materials, which are dispersed in various online web site locations, can be a daunting task for a new reader to the subject of NG9-1-1, and sometimes even so for a seasoned industry professional. Various topic areas relevant to NG9‑1‑1 are listed in this document to orient a 9-1-1 Authority person in search of context specific information. The topic area contains a very brief description and a list of references is given. The references contain a pointer to the most relevant portions of the referenced document for a reader to focus on to gather an understanding of that topic area. The reference pointers are just a beginning shortcut for a reader to focus on, as only a complete reading of the materials referenced can fully provide the background information a reader should understand to make an orderly and progressive transition to NG9-1-1.

= Planning for NG9-1-1 Transition =

While the development of technical standards and related information is still ongoing, there are many actions that 9-1-1 Authorities should consider in preparing for transitioning to an NG9-1-1 environment. These actions relate mostly to the preparation necessary to lay the proper foundation for this transition. At a high level, this process is relatively logical, and involves efforts to identify and organize the following Project Management actions:


 * Initiatives: Education, governance, scope &amp; goals
 * Drivers: cost factors, emergency event response, institutional, statutory, geo-political situations, opportunities and constraints
 * Constraints: Identify the bounds within which the initiative will need to exist
 * Requirements: What kind of service environment is called for
 * Inventory: What is already in place and what is missing
 * Partnerships: Build Inter-local/inter-authority relationships and communication channels, including the current provider of emergency services
 * Specific Actions: Establish coordination of roles and responsibilities, Funding sources, Documentation, and Performance Measurement Metrics
 * Planning: Technological and Operational deployment, training, communication, testing, and go-live plans and procedures.

More specifically, the remaining topics within section 3 provide additional detail on activities related to these project management actions.

Self-education
Educate the 9-1-1 Authority planning team to understand what NG9‑1‑1 involves and its impacts across Emergency Services Internet Protocol networks (ESInet), NG9-1-1 services (applications &amp; databases), roles, responsibilities and operational procedures. Self-education can span across all references provided in this document, but at a minimum, the below references and a basic understanding of what is important in NG9-1-1 when educating the planning team. This is especially true when comparing NG9-1-1 and the Public Safety Broadband Network (FirstNet).

Governance
Establish a service management (governance) structure with the authority to engage in the project. Recognizing that NG9‑1-1, by nature, reflects layered, interconnected systems, initial transition steps will in many cases occur at local and regional 9-1-1 Authority levels. Those activities, in turn, may progressively link together into larger regional NG9-1-1 systems. That leads to a logical role for states to deploy resources to help support and/or ensure statewide connectivity. Governance structures will need to be established to manage these intergovernmental arrangements, unless such mechanisms already exist. Among other things, agreements governing such arrangements will address relative management roles, responsibilities, and cost sharing. Ultimately, there is no single answer to how these systems will interconnect, and how related governance systems will evolve. Factors that will impact this include things like:

  Local, regional, and state emergency event response considerations   Historical institutional, statutory, geo-political culture, arrangements and related environment   Joint service environment (both existing and proposed)   Resource and cost sharing opportunities, factors and constraints Note: Whatever intergovernmental arrangements are put in place to explore, coordinate and plan for these matters may not necessarily reflect the long-term arrangement necessary to oversee and manage the system(s) involved.

Communications Plan
Develop a plan to open lines of communications among the stakeholders throughout the life of the project. Consider the below questions as the Communications Plan is developed:

  Context – what’s happened before? What’s the history?   Environmental Scan – what are the key factors that will affect your success? What is the current situation driving the need for change?   Stakeholders – Identify your stakeholders and their expected reactions. How you will manage them? </li>  Objectives – what do you want to achieve? (should be clear, relevant, measurable) </li>  Strategy – where are you going and why? What are the major activities to move the effort forward? </li>  Audiences – who are the key audiences? </li>  Announcement – given the strategy, are you making an announcement? What are you announcing? </li>  Messages – what are you saying about the announcement? </li>  Tactics – how will you implement your strategy, both before, during and after the main announcement? </li>  Issues – what problems may you have to overcome? </li>  Budget – what will the communications strategy cost? </li>  Evaluation – how will you know if you’ve been successful? The general sections of a communications plan can vary depending on the local environment and the scope of the planned NG9-1-1 effort. This is a sample Communications Plan from a statewide NG9-1-1 effort. </li></ul>

Sample Communications Plan
The general sections of what a typical communications plan might contain are shown below. Inclusion of a specific section shown below will depend on the local environment and the scope of the planned NG9-1-1 effort. The communication plan will likely evolve over time and the contents might vary during the transition effort to NG9-1-1.


 * Purpose
 * Goals and Objectives for NG9-1-1 Specific Communications
 * Stakeholders and Roles
 * Communications Policy and Objectives
 * Communication Channels, Targets and Frequency
 * Communications Plan Activities
 * Mid to Long-term Communications Activities
 * Communications to Support NG9-1-1 Milestones
 * Educational Communications Strategy
 * PSAP and GIS Locality Specific Planning.

Statement of Documentation
Establish a library function to memorialize the project. Pertinent documents and communications should be assembled in a formal manner to allow audit and remedial processes. Ensure that all terms used in Project related documents are very clear to all users of the documents, even those who may have a less active role, especially those in control of providing the necessary funding. Utilize document management tools wherever possible including standardized file name structures and metadata tagging.

Estimated Scope and Project Timelines
This is an early statement of expectations. At a minimum, the agencies expected to have access to the NG9-1-1 system should be identified. The scale of the project, such as regional or state level, must be considered (see Governance). If the network is intended to transport more than 9-1-1 calls, (e.g., NCIC, IP radio, Poison Control), specify exactly what other emergency services applications are intended to be supported on the network. This helps establish the network engineering criteria for the systems involved. Resource and cost sharing may occur at basic network levels, and must be factored into this analysis.

When scope and governance are identified, a project definition and timeline should be initiated, for review and approval with project stakeholders.

Budget &amp; Funding
Create a preliminary budget based upon estimated costs to deploy NG9-1-1 and evaluate recurring costs. Additionally, current funding sources should be evaluated in order to determine whether transition costs can be covered. If any gaps exist, new funding sources will need to be identified in order to close the gap.

Data Inventory &amp; Standardization
For Data Inventory and Standardization, data sources should be identified for use in the development of this project. For example, while the Master Street Address Guide (MSAG) is required as a data source, this project will require migration from tabular data to a combination of tabular and spatial data. A clear understanding of the source of all required data, including spatial/mapping data stored in a Geographic Information System (GIS), ownership, responsibility and maintenance must be established.

Establish Performance Measurement Metrics
To establish Performance Measurement Metrics, determine the methodology that will be used to ensure that network and system operation and reliability meet acceptable and adopted standards. Solutions should provide the capability to monitor, record, and analyze system performance data against predefined metrics (i.e., establish system norms and flag exceptions). A key element of reliability is security and specifically Cybersecurity which should be addressed during all phases of planning, deployment and testing.

Network Analysis
For the geographic area being served, an analysis of existing broadband infrastructure must be developed. The analysis should be as complete as possible and include both private and public facilities. Record both the network architecture design and signaling used for each identified source of bandwidth and associate each with the user-stakeholder location. Where possible, note areas that lack physical diversity, so they can be analyzed further for possible remedies to lessen the risk of service failures. Consider how this area will interconnect with adjoining networks. Assess the need to interconnect with the E9-1-1 System Service Provider for routing and bridging of 911 calls. This may be needed when originating carriers remain supported by the legacy Selective Router and the appropriate Public Safety Answering Points (PSAPs) have transitioned to the NG9-1-1 system. It may also be necessary if calls are to be bridged between PSAPs supported by the NG9-1-1 system and those remaining on the legacy emergency system.

Socialization and Education
For socialization and education once the steps above have matured to a point where they can be expressed in common language, use your “Communications Plan” to begin the process of describing the project its current state and estimated timelines to your stakeholders. Keep in mind an important part of this process is answering the question of “what’s in it for me” from the perspective of all stakeholders.

PSAP Inventory
If there is no central repository for information regarding the equipment and software inventories within the PSAP, one must be assembled. Going beyond just Call Handling application, this inventory should be as granular as reasonably possible, and may include items such as types of Computer Aided Dispatch (CAD), other public safety applications, mobile data applications, control of radio consoles and related administrative communications, used in the PSAP operational environment. These documents must be kept open for updates on a regular basis. This activity supports overall planning, and includes identifying opportunities to share resources, and assists in ensuring interoperability.

Refinement of Scope
Using input from the former tasks, develop a refined, realistic scope for the project. Specificity and clarity are required of this step and it is urged that the entire stakeholder community be aware of the scope.

USDoT NG9-1-1 POC Test Plan : Appendix D – Use Case Tests.

Deployment and Testing Planning
Creation of a plan for deploying and testing, even if incomplete must begin prior to the “Acquisition” phase of the project. Reasonably estimate the amount of effort not only for the public agencies including central 9-1-1 Authority groups, but the provider community as well. Assess the interaction and testing that may be required with the SSP (there may be more than one). Use a methodical approach to deployment and expect a thorough test period prior to going live with any installation. This plan, including specific test scripts must be in written form. Initially the test scripts might be high level. But before testing begins, those high-level scripts will need to be detailed and shared with all impacted stakeholders. Everyone involved in testing must understand their role and responsibility.

Acquisition
Acquisition is usually done as a Request for Proposal (RFP) or similar. Acquisition may be done as a single provider solution or be provided by more than one source. Regardless of how the solution is acquired, local and state procurement laws will dictate the process.

Go-Live
A Go-Live Checklist should be developed to be used to determine if all procedures, system capabilities, fallback or failover considerations, and interoperating systems are ready for cutover to live operations on the NG9-1-1 system. Among possible items for such a high-level checklist are the following:


 * Has compliance been achieved with all statutes or regulations that allow a state, regional, or local 9-1-1 authority to deploy, operate, or manage software-and database controlled NG9-1-1 systems?
 * Does the 9-1-1 Authority have sufficient jurisdiction to implement NG9‑1‑1 emergency service IP networks to replace dedicated 9-1-1 systems that are shared among multiple emergency response entities?
 * Are existing liability protection statutes or regulations in place to cover all services and

information that may be delivered over NG9-1-1 systems and shared among emergency

response entities (e.g., voice, sensors, images and other data, video, medical records, and any new, not yet developed, product or service)?
 * Are existing privacy, confidentiality, disclosure, and retention statutes or regulations sufficient to apply to all types of 9-1-1 calls and call content that are possible with an NG9-1-1 system (e.g., voice, data, images, video, information from third-party databases added to a 9-1-1 call record)?
 * Has full coordination and planning been achieved with Originating Service Providers (OSPs) to allow native delivery of emergency calls via Internet Protocols?
 * Are all system maintenance and Service Level Agreements in place to allow the NG9-1-1 network and system to be managed and operated operate in a secure 24/7/365 fashion?
 * Have all Policy Routing Rules and Call Diversion strategies been established and agreed to with surrounding jurisdictions?
 * Has a rollback plan been developed that would be implemented if the Go-Live is not successful? For instance, if a situation at the PSAP requires a physical evacuation to the organization’s backup facility, the secondary location must can begin live operations relatively quickly and not be susceptible to service interruptions.
 * Has all system and end-user training been completed to ensure the user community and

maintenance staff are prepared to operate and support the system?
 * Has a complete treatment of verification and validation taken place to ensure GIS data for NG9‑1‑1 meets or exceeds the NENA 98% accuracy threshold?
 * Has the NG9-1-1 Service Provider completed all Operational Readiness Tests of the network to include end-to-end tests, integration with NG9-1-1 Core Services Functional Elements, system and network failover tests, third-party integration tests, and Call Handling System integration tests?
 * Has consideration and planning for denial of service attacks, telephony denial of service attacks and other cybersecurity protections been completed and thoroughly tested?
 * Are the necessary call and system performance metrics for NG9-1-1 identified and able to be captured within reporting and systems and management monitors to allow the 9-1-1 Authority to measure system performance and to monitor key performance thresholds?
 * Is there a detailed Transition Go-Live Plan (including tasks delineated in hourly increments with specific individuals assigned to tasks for Go-Live Day) in place with all system and network partners? A well-coordinated and well-documented cutover plan is needed to systematically and efficiently make the cutover from the legacy 9-1-1 system and legacy Service Provider to taking calls with the new SSP within the NG9-1-1 system.

Management and Maintenance
As an ongoing element of the project, both the provider and public stakeholder will have a role in continual management and maintenance of the NG9-1-1 system and its components. Maintenance becomes an active part of the” Statement of Documentation” process and will remain an active role throughout the life of the network and system.

A comprehensive list of references is found below. The reader should be aware of an annual effort undertaken by the National 911 Program to prepare a document, “The Next Generation 911 (NG911) Standards Identification and Review” document. The Next Generation 911 (NG911) Standards Identification and Review document is a compilation of existing and planned standards for NG9-1-1 systems distributed by the National 911 Program, a department of the National Highway Traffic Safety Administration of the US Department of Transportation. The mission of the National 911 program is to provide federal leadership and coordination in supporting and promoting optimal 9-1-1 services.

The NG911 Standards Identification and Review document is updated annually to reflect the latest status in NG911 and related standards. It is a living document that contains information on various standards activities related to NG911. The document includes a description of the importance of Product, Interface, Data, Design, Test, Performance, and Operational standards, and provides information on the best practices, stakeholders, and standards organizations. The document highlights NG9-1-1/ESInet standards but not lower level standards such as SIP and VoIP.

The core of the document includes references to standards documents from the various organizations including 3GPP, APCO, ATIS, DOC, FCC, ISAO, NENA, and USTelecom. All of the relevant standards committees are also listed. The appendix to the document contains a table with all NG9-1-1 standards documents listed with information on their relevance to the NENA i3 Architecture. The standards documents are categorized based upon whether they relate to Client, Access Networks, Origination Networks, NG9-1-1/ESInets, or PSAPs.
