The selected method is the remote method, as defined in ISO/IEC 9646-2 5, clause 11. This test method has been selected, because: - - -
38、this test method implies no specific requirements from the Implementation Under Test (IUT); the upper Service Access Point (SAP) of the IUT cannot be directly observed; the variety of the possible TETRA implementations is a serious technical obstacle for the adoption of a different ATM; - this test
39、method places minimum limitations in the realization of conformance testing. The DM-REP2 MAC protocol defines the operation of a DM-REP2 serving two air interfaces, the master and the slave link. To test the repeater operation in some cases both interfaces need to be controlled and observed simultan
40、eously. This implies that two testing methods are used: the remote single-party test method (with one PCO) and the remote multiparty test method with two PCOs. 4.1 Single PCO testing The remote Single Party test method with a single PCO is illustrated in figure 1. , PCO GASPS TCP MAC- PDUS lu1 Figur
41、e 1 : Remote SPyT test method for TETRA DM-REP2 MAC layer 4.1 .I Lower Tester (LT) A LT is located in a remote TETRA test system. It controls and observes the behaviour of the IUT. 4.1.2 Upper Tester (UT) There is no explicit UT in the remote test method, but the DM-REP2 MAC layer and the layers abo
42、ve inside the System Under Test (SUT) are used implicitly for testing the MAC layer. 4.1.3 Test Coordination Procedures (TCP) The implicit send events defined by the provider of an implementation in annex B serve the purpose of the TCP. They are used as an input to the IUT communicating with the UT
43、to initiate test events at the DMO MAC layer. ETSI 9 ETSI EN 300 394-4-1 4 V1.l.l (2001 -01) 4.1.4 Point of Control and Observation (PCO) All test events at the PCO carrying service user data are specified in terms of MAC layer PDUs. Only few Abstract Service Primitives (ASPS) are defined for contro
44、l or observation purposes. The mapping of the MAC PDUs into the physical layer frame structure is left to the test implementation. 4.2 Multiple PCO testing The selected test method is illustrated in figure 2.

They observe the behaviour of the IUT. They are controlled and syn
46、chronized by the lower tester control function. 4.2.2 Upper Tester (UT) There is no explicit UT in the remote test method, but the layers above inside the System Under Test (SUT) are used implicitly for testing the DM-REP2 MAC layer. 4.2.3 Test Coordination Procedures (TCP) The implicit send events
47、defined by the provider of an implementation in annex B serve the purpose of the TCP. They are used as an input to the IUT communicating with the UT to initiate test events at the MAC protocol layer. ETSI 10 ETSI EN 300 394-4-1 4 V1.l.l (2001 -01) 4.2.4 Point of Control and Observation (PCO) The PCO
48、s are located inside the protocol. All test events at the PCOs carrying service user data are specified in terms of MAC PDUs. The mapping of the PDUs to possible physical layer service primitives is left to the test implementation. 4.3 Test configurations and use of concurrent TTCN As this ATS cover
49、s both single-party testing using non-concurrent TTCN, and multi-party testing using concurrent TTCN, the notation chosen for the complete ATS is concurrent TTCN syntax. Therefore, tests components are defined to describe the two configurations: the “single-party“ configuration and the “multi-party“ configuration, as shown in figures 3 and 4. The single-party configuration is used in case of single-party testing, i.e. for testing a single air interface only, a master link or slave link interface. In this case only a
