1. P25 Compliance Assessment Program
Presented by:
The
Project 25 Technology Interest Group

2. P25 Compliance Assessment Program Goal
Ensure that different manufacturers’ equipment interoperates and complies to the related P25 standards

3. 3 Steps to P25 Compliance Performance Conformance Interoperability
Addressed in TIA committees TR-8.1 (Measurement Procedures) and TR-8.6 (Recommended Performance)
Implementation/endpoint behavior/interface is ‘legitimate’ – it meets minimum requirements as specified in the standard
Must pass performance testing before proceeding to conformance testing
“can do this alone – test equipment only”
Conformance
Implementation/endpoint behavior/interface responds to the receipt of a message (stimulus) as specified in the documented standard.
Check for proper order and content of messages as specified in the standard
Fixed Station Interface example: Air Interface stimulates Fixed Station, FSI puts an appropriate message on the wireline side
Interoperability
The equipment from one manufacturer interacting with equipment from another manufacturer can successfully provide a mandatory or standard option service. (Functional Test)
This definition is consistent with the Interoperability Testing documents authored by ITS.
“cannot do this alone – need the other manufacturer’s involvement/equipment”

4. P25 Compliance Committees Background
Compliance Assessment Process and Procedures Task Group (CAPPTG) drafts interoperability and conformance testing documents
Hosted Manufacturer Interoperability Board (HMIB) formed to investigate fielded interoperability issues and reach consensus on resolutions
Work from HMIB developed into a formal TIA SubCommittee TR8.25
TR8.25 Compliance Assessment SubCommittee formed to address interoperability issues and to incorporate the other facets of Compliance
NIST – National Institute Standards and Technology
OLES – Office Law Enforcement Standards

5. CAPPTG Compliance Assessment Process and Procedures Task Group
Scope
Ensure that Project 25 equipment and systems comply with P25 standards for interoperability, conformance, and performance regardless of manufacturer and in accordance with the User Needs Statement of Requirements.
Identify pertinent interoperability, conformance, and performance test procedures not addressed by other APIC and TR8 committees
Develop appropriate procedures in the form of applicable DRAFT documents which will then be forwarded for approval to TR8 Engineering Committees via APIC and the P25 Steering Committee
Review current standards and specifications to ensure that features and functions are consistent with the goals of interoperability, in accordance with defined user needs.
Assess as required the mandatory and optional messages as prescribed by users; and create implementation guidelines for system level interoperability

6. TR8.25 Compliance Assessment
Scope
Responsible for the resolution of compliance assessment related questions.
Investigate questions of Conformance, Performance (i.e. measurement methods), and Interoperability
Recommend a resolution, test compatibility of the resolution with existing implementations, and then migrate the impacted standard in the recommended direction.
New standards do not invalidate older products validated by previous standards.
Responsible for the development and publication approval of identified TIA standards for Project 25 Conformance, Performance, and Interoperability not assigned to other TIA TR-8 subcommittees.

7. Compliance Assessment Work
Trunking and Conventional Interoperability Testing Documents updates– TIA102CABC and TIA102CABA
Trunking and Conventional conformance tests (P25 Conformance Profiles (PCPs))
Phase 1 Trunking and OTAR interoperability updates

8. SAFECOM Grant Guidance FY 2007
The FY 2007 SAFECOM Recommended Federal Grant Guidance states that grant applicants using funds to purchase Project 25 (P25) equipment must obtain certain documented evidence from the manufacturer. The evidence should show that the equipment has been tested to, and has passed, all of the applicable, published, and normative P25 compliance assessment test procedures for performance, conformance, and interoperability. These procedures are defined in this document. Applicable test procedures include tests of all mandatory features and standard options installed in the product contemplated for purchase. The compliance assessment requirements for P25 are listed below.

9. SAFECOM Grant Guidance FY 2007
Subscriber Units
1.1. Performance. Subscriber units shall be tested in accordance with the following sections of
ANSI/TIA-102.CAAA-A1, and shall meet or exceed all of the minimal performance
recommendations (or Class B requirements where applicable) as specified in ANSI/TIA-
102.CAAB-A.2
§2.1.4 Reference Sensitivity
§2.1.5 Faded Reference Sensitivity
§2.1.6 Signal Delay Spread Capability
§2.1.7 Adjacent Channel Rejection
§2.1.8 Co-Channel Rejection
§2.1.9 Spurious Response Rejection
§ Intermodulation Rejection
§ Signal Displacement Bandwidth
§ Late Entry Unsquelch Delay
§ Receiver Throughput Delay
§2.2.8 Unwanted Emissions: Adjacent Channel Power Ratio
§ Transmitter Power and Encoder Attack Time
§ Transmitter Throughput Delay
§ Frequency Deviation for C4FM
§ Modulation Fidelity

10. SAFECOM Grant Guidance FY 2007
1.2. Conformance
Basic Conventional Mode Operation - No tests defined or required
Advanced Conventional Mode Operation - No tests defined or required
Basic Trunked Mode Operation - No tests defined or required
Advanced Trunked Mode Operation - No tests defined or required
1.3. Interoperability –
Conventional Mode Operation - No tests defined or required
Trunked Mode Operation.
P25 subscriber units capable of trunked mode operation shall be interoperability tested in accordance with the Project 25 Interim Standard. Subscriber units must be tested against at least a majority, i.e. more than 50%, of the commercially available, band compatible trunked systems (excluding trunked systems produced by the manufacturer of the subscriber unit under test).

11. TIA Response
January 2007: P25 Steering Committee passed a motion that developing a conformance process and compliance testing is a high priority
SAFECOM Grant Guidance - Supporting Documents
Identify tests required for a manufacturer to claim compliance
Identify information to be included in the compliance reports to ensure that tests and results are repeatable
Identify information to be included in a Supplier’s Declaration of Compliance
