This document is intended to test aspects of the operation of
\nsubscriber and Radio Frequency Sub-System (RFSS) equipment in the
\ninterests of adhering to key aspects of the Two-Slot Trunked TDMA
\nVoice Services Common Air Interface MAC protocol as described in
\n[R1]. It includes a set of CP items for primitive operation. A CP
\nis a conformance test consisting of set of preconditions and input
\nparameters that result in an expected output from a Unit Under
\nTest. The CP nomenclature provides an independent conformance test
\nnumbering system that is unique with this Standard and not
\ndependent on the paragraph, clause, or subclause numbering used in
\nthe document. The CPs are:<\/p>\n
CP 1 – Burst Field Conformance Tests<\/p>\n
\nTests the Reed Solomon encoder.<\/p><\/blockquote>\n
CP 2 – Transmit Voice Channel Conformance Test<\/p>\n
\nTests the modulation polarity, construction, coding,
\ninterleaving, and scrambling of individual bursts, superframes, and
\nultraframes.<\/p><\/blockquote>\nCP 3 – Receive Voice Channel Conformance Test<\/p>\n
\nTests the error correction of the decoders in the
\nreceiver.<\/p><\/blockquote>\nIn general, the standard defines test messages, which are
\nencoded and processed to generate expected test vectors which are
\ndocumented in Annex A, as well as in text files distributed with
\nthe standard document. An expected test vector can be an
\nintermediate encoded codeword or can represent bursts that could
\noccur on the Phase 2 Two-Slot Time Division Multiple Access \u2013
\nTrunked Voice Services Common Air Interface.<\/p>\nA test of a transmitter function in a UUT, such as an encoder,
\nconsists of applying a test message to the transmitter function,
\nand recording the output that results. This output from the UUT is
\nthen compared with the expected test vector to verify correctness.
\nIn a test of a receiver function in a UUT, the test vector is
\napplied to the receiver function, perhaps with transmission errors,
\nand the receiver output is then recorded. If the receiver corrected
\nthe errors, then the output of the receiver should match the
\nexpected message for correctness.<\/p>\nThe test messages and test vectors used in the transmitter tests
\nCP 1 and CP 2 are selected to exercise the modulator and non-voice
\nencoders of the transmitter under test for various codes used in
\nthe Two-Slot Trunked TDMA Voice Services Common Air Interface [R1].
\nIn CP 3, test vectors defined in CP 1 and CP 2 are applied as input
\nto test the receiver response. The test vectors used are selected
\nto exercise the error correcting and detecting mechanisms of the
\nnon-voice decoders of the receiver under test. The functionality
\nproduced by the receiver is not tested in these tests but can be
\ninferred from the information content of the test input, the
\nconditions of the test, and the operating characteristics of the
\nreceiver.<\/p>\nThis document is intended for use by manufacturers to serve as a
\nstandard reference for verifying adherence to the MAC protocol as
\ndescribed in [R1], as a means of assisting manufacturers in the
\ndevelopment of interoperable equipment, and as a means of assisting
\nmanufacturers in the diagnosis of interoperability issues, should
\nthey occur. This document is not designed for use as a functional
\ntest suite. This document assumes an audience familiar with terms
\nand definitions contained in the standards.<\/p>\n","protected":false},"excerpt":{"rendered":"Project 25 – Phase 2 Two-Slot Time Division Multiple Access Trunked Voice Services Common Air Interface Conformance Specification<\/b><\/p>\n
