Until now, there's been no nationally accepted definition of what interoperability means or when and why it's needed, said David Boyd, director of the Safecom program, which developed the page document. This consensus is important not only because of the breadth of needs outlined in the document but also because it represents the needs of the users at every level of government, said Stuart McKee, chief information officer for Washington state.
Although communications interoperability has been a priority for officials nationwide for years, this is the first time there has been a document developed with this level of consensus, McKee said. Boyd characterized the statement of requirements as a living document that will grow and address future needs to include data, images, video and other capabilities. Therefore, it is not technology-specific. The document, he said, will provide industry with information about the capabilities they should incorporate into systems for first responders.
But he also said it provides state agencies and local communities with a powerful tool to justify their communications needs to lawmakers.
Safecom's statement of requirements comes eight years after the last major federal report issued by the now-defunct Public Safety Wireless Advisory Committee on wireless communications for the 50, public safety agencies nationwide.
But unlike that document, Safecom's new report does not focus on spectrum issues. Boyd said the White House Task Force on Spectrum Management will issue a report on radio spectrum by the end of the year.
Officials wanted to focus on baseline requirements that will help address spectrum, technology and other problems. The statement of requirements also addressed a recent General Accounting Office report that criticized the Safecom program in the past for its slow progress and cited the need for detailed agreements among all involved. Safecom officials have at least one solicitation for interoperability solutions already lined up to be based on the requirements.

The architecture framework will provide public safety agencies with the necessary tools to compare and integrate legacy communication and information systems and allow them to leverage resources and migrate towards interoperability. The PSAF provides practitioners with a set of tools and a common lexicon for describing the elements of their local communications systems and enables practitioners to compare capabilities and equipment to achieve interoperability between jurisdictions.
In addition to assisting the SAFECOM program in identifying needed standards by highlighting compatibility problems at key communications interfaces, the PSAF will also serve as a guide for localities planning for interoperability or technical capability upgrades.
The PSAF enables engineers and planners to document their current public safety communication capabilities and analyze their system in relation to other systems.
Ultimately, the PSAF will provide public safety with the ability to examine and develop both their operational and communications system capabilities. With the publication of the PSAF in early , OLES and SAFECOM are moving forward with a trial to demonstrate the utility of architecture framework principles within the public safety community by developing a database driven application which doesn't require enterprise architecture expertise.
The CASM tool's baseline capabilities, which gather operational data, will be extended to gather more technical details of a communications system. Public safety agencies participating in the trial activity will apply their real world experience to shape and define the tool and ensure it and the underlying architecture framework process are user friendly.
In early three Project 25 interfaces were identified as crucial for public safety agencies to purchase and implement both operable and interoperable Pcompliant systems. Those interfaces are listed below and represent where the most effective acceleration of the P25 Standards occurred in the past year and a half. While the initial releases will not fully satisfy all of the users' requirements, they will allow manufacturers to build interoperable equipment possessing the most common, basic features.
Since then OLES has worked with representatives from both user and industry communities to focus the efforts of the program and to develop an initial framework for the assessment program. A key accomplishment of this group was a memorandum of understanding stipulating the basic assumptions for testing and the means by which test results would be collected and disseminated.
That group has established a basic framework for the program and decided upon a fi rst-party testing regimen to back a Supplier's Declarations of Compliance. OLES representatives drafted and the committee accepted a work plan that prioritized the various conformance and interoperability test procedures—the test procedures that underpin the compliance assessment program. Testing of the CAI begins with evaluations of interoperability for both trunked and conventional mode operation and are on track for completion by the end of calendar year Work is ongoing to update and publish more complete interoperability test procedures, and conformance test procedures for the CAI will follow.
Testing of wireline-based interfaces such as the ISSI poses additional challenges not the least of which is the need for new test equipment and metrology. In addition, the tool will include a packet capture and visualization tool that will support system analysis and troubleshooting.
OLES is driving the broadband standardization effort on behalf of public safety. OLES leadership in this area is evidenced by its sponsorship of the Chair for the APIC Broadband Task Group, and its support from the public safety community derives from its commitment to faithfully representing their requirements. The goal is for public safety to be able to quantify their specific spectrum needs and tie these needs directly back to a repeatable simulation effort.
