TIA-102.CADA i FORWARD This document has been developed by the APCO Project 25 Interface Committee (APIC) Fixed Station Interface Task Group (FSITG) for possible publication as a TIA standard. TIA Standards are designed to s
23、erve the public interest by eliminating misunderstandings between manufacturers and purchasers, facilitating interoperability, interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining the proper telecommunications product for their particular need. Exist
24、ence of such Standards shall not in any respect preclude any Member or non-Member of the TIA from manufacturing or selling products not conforming to such Standards. Except as provided in the Engineering Manual, Standards are proposed or adopted by the TIA without regard to whether their proposal or
25、 adoption may in any way involve patents or intellectual property on articles, materials, or processes. By such action, the TIA does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting TIA Standards, to parties manufacturing or selling product
26、s or services conforming to such Standards or to users of such products or services. Other TIA rules respecting Standards where patents are involved are contained in the Manual and should be read in conjunction with these Guides-PV. Furthermore, in all cases specific requirements and restraints expr
27、essed elsewhere in these Guides must govern. TIA-102.CADA ii PATENT IDENTIFICATION The readers attention is called to the possibility that compliance with this document may require the use of one or more inventions covered by patent rights. By publication of this document, no position is taken with
28、respect to the validity of those claims or any patent rights in connection therewith. The patent holders so far identified have, we believe, filed statements of willingness to grant licenses under those rights on reasonable and nondiscriminatory terms and conditions to applicants desiring to obtain
29、such licenses. The following patent holders and patents have been identified in accordance with the TIA intellectual property rights policy: No patents have been identified. TIA shall not be responsible for identifying patents for which licenses may be required by this document of for conducting inq
30、uiries into the legal validity or scope of those patents that are brought to its attention. TIA will neither be a party to discussion of any licensing terms or conditions, which are left to the parties involved, nor will TIA opine or judge whether proposed licensing terms or conditions are reasonabl
31、e or non-discriminatory.

This conformance document is part of a document
37、suite describing all pertinent requirements of the Project 25 Fixed Station Interface. The Fixed Station Interface document suite includes the following: Overview Messages and Procedures Measurement Methods Performance Recommendations Conformance Test Procedures (this document) Interoperability Test
38、 Procedures 4.1 Definition of Conformance Testing The important factors which characterize conformance testing are as follows: The Implementation Under Test (IUT) defines the boundaries for testing - by boundaries one can only test functionality that the IUT is capable of; The tests are executed by
39、a dedicated test system that has full control and observes the IUTs behavior. The tests are performed on open standardized interfaces. Because the test system controls the sequence and contents of the protocol messages sent to the IUT, it can explore a wide range of expected behaviors. TIA-102.CADA
40、4 Conformance Tests verify the correct procedure and messaging has occurred in order to achieve the appropriate end result, e.g., verification of the order and content of a series of control tones resulting in the desirable behavior of the Implementation Under Test (IUT), an analog fixed station in
41、this particular case. The specific test cases for the fixed station interface are selected to exercise the interface functionality. In general the interface tests can be applied to a fixed station by exciting the interface with the test signals from simulation hosts and then measuring the fixed stat
42、ions response. 4.2 Types of Conformance Tests There are several types of tests which may possibly be applied to the Implementations Under Test. 4.2.1 Basic interconnection tests: These establish that there is sufficient conformance for interconnection to be possible, and that the main features of th
43、e protocol are implemented, without undergoing thorough testing. Basic interconnection tests are standardized (part of the standard conformance test suite). 4.2.2 Capability tests: The capability tests check that the observable external static capabilities of the implementation are valid with respec
44、t to the static conformance requirements expressed in the performance specifications of the IUT. Capabilities tests are standardized (part of the conformance test suite) and mandatory. 4.2.3 Behavior tests: These tests check, as thoroughly as practical, the dynamic conformance of an implementation w
45、ith respect to the dynamic conformance requirements specified in the protocol standard Messages and Procedures document. The implementation is submitted to a specific number of combinations of events and timing of events, as defined in a test suite. The behavior of the IUT is checked by the tester a
46、nd, according to the presence or absence of error, the IUT is declared conformant to a specific aspect of the protocol specifications covered by this test, or non conformant. In other words, the verdict of each test case is either Pass (meaning conformant), Fail (not conformant), or Inconclusive if
47、no definite conclusion can be derived from this test. Behavior tests are standardized (the test suite being standardized) and mandatory.
