26、r Tester 4 Abstract Test Method (ATM) This clause describes the ATM used for testing the DECT DLC protocol. It is the embedded variant of Remote Single (RSE) layer test method. The RSE test method has been selected, because: - - - this test method implies no specific requirements from the IUT; the U

27、pper Service Access Point (USAP) of the IUT cannot be directly observed; the variety of the possible DECT implementations is a serious technical obstacle for the adoption of a different ATM; ETSI 8 ETSI EN 301 469-5 V1.l.l (2000-1 O) - this test method places the minimum limitations in the realizati

28、on of conformance testing. The embedded variant of the remote test method provides sufficient control of the IUT DLC behaviour, through NWK layer messages conveyed by DLC frames.

29、r Tester (LT) is located in a remote DECT test system. It controls and observes the behaviour of the IUT. MSAP MAC Service Access Point - A unique MAC SAP is defined at the DECT interface and used to exchange service data of the DLC protocol. To avoid the complexity of data fragmentation and recombi

30、nation testing, the SAP is defined below this functions of the DLC layer. PCO The PCO for DLC layer testing is located on the MSAP. All test events at the PCO are specified in terms of MAC Abstract Service Primitives (ASPS) and DLC layer Protocol Data Units (PDUs). Notional UT No explicit upper test

31、er (UT) exists in the system under test. Nevertheless, some network messages are sent to the SUT for the need of the co-ordination procedures. The network layer of the SUT is used as a notional UT as defined in IS0 9646. The MAC primitives are defined according to EN 300 175-3 i clause 8 and associa

32、ted subclauses. 5 Untestable Test Purposes (TP) Due to the ATM chosen for this ATS or other restrictions, the test purposes in table 1 have been identified as being in the untestable category, and therefore have not been derived into final test case: ETSI 9 ETSI EN 301 469-5 V1.l.l (2000-1 O) Table

33、O: Untestable TP Test purpose I Reason 6 ATS Conventions This clause describes the conventions applied to define the ATS and gives the naming conventions chosen for the different elements of the ATS. The ATS conventions are intended to give a better understanding of the ATS but they describe also th

34、e conventions made for the development of the ATS, thus for any later maintenance purposes or further development of the ATS the conventions described in this clause shall be considered. The ATS conventions contain two subclauses, the naming conventions and the implementation conventions. The naming

35、 conventions describe the structure of the naming of all ATS elements. The implementation conventions describe the functional structure of the ATS. To define the ATS, the guidelines of ETS 300 406 3 was considered. 6.1 Naming conventions 6.1.1 Declarations part This subclause describes the naming co

36、nventions chosen for the elements of the ATS declarations part. 6.1 .I .I Test suite type and structured type definitions The test suite type and test suite structured type identifiers describe the information elements, and are written in uppercase: EXAMPLE: PROTOCOL-DISCRIMINATOR simple type. FILLS

37、TRING structured type. 6.1 .I .2 Test suite operations definitions The test suite operation identifiers are composed of substrings in lowercase letters, except for standard prefix “TSO-“. Each substring is separated by an underscore character (I-I). EXAMPLE: TSO-compute -checksum. 6.1 .I .3 Test sui

38、te parameter declarations The test suite parameter identifiers are composed of substrings in lowercase letters, except for the standard prefix “TSP-“. Each substring is separated by an underscore character (I-I). EXAMPLE: TSP-window-size. If the test suite parameter references a Protocol Implementat

39、ion Conformance Statement (PICS) item, the letter “C“ is added to the standard prefix. EXAMPLE: TSPC-pics-item-s23. If the test suite parameter references a PIXIT item, the letter “X“ is added to the standard prefix. EXAMPLE: TSPX-pixit-item-2. ETSI 10 ETSI EN 301 469-5 V1.l.l (2000-1 O) 6.1 .I .4 T

40、est case selection expression definitions The naming conventions for the test case selection expression definitions use free text starting with an uppercase letter. The name of the expression shall explain clearly the selection rule. The test case selection expressions are logical combinations of th

41、e test suite parameters definitions. 6.1 .I .5 Test suite constant declarations The test suite constant identifiers are composed of substrings in lowercase letters, except for the prefix “TSC-“. Each substring is separated by an underscore character (I-I). EXAMPLE: TSCretry. Complete names as define

42、d in the specifications are used. 6.1 .I .6 Test suite variable declarations The test suite variable identifiers are composed of substrings in lowercase letters, except for the prefix “TSV-“. Each substring is separated by an underscore character (I-I). EXAMPLE: TSV-count. Exception: If the test sui

43、te variable represents a system parameter or value, the name defined in the specifications is used. EXAMPLE: VR,VS . 6.1 .I .7 Test case variable declarations The test case variable identifiers are composed of substrings in lowercase letters, except for the prefix “TCV-“. Each substring is separated

44、 by an underscore character (I-I). EXAMPLE: TCV-cr-value. 6.1 .I .a PCO declarations The point of control and observation identifiers are composed of two or four capital letters, beginning with “L“, as there are only LTs. EXAMPLE: LMAC represents a PCO on MAC interface as LT in the test equipment. L

45、DLC represents a PCO on DLC interface as LT in the test equipment. 6.1 .I .9 Timer declarations Two kinds of timers can be distinguished: i) standardized: Those defined in the standard, e.g. DL-04, use exactly the same name as in the standard, beginning with a capital “T“. As there is a tolerance ma

46、rgin accepted for these timers, three values are needed: - the maximum value allowed, which will use the suffix “-max“; - - the minimum value allowed, which will use the suffix “-min“; the value actually implemented, with no suffix. EXAMPLE 1 : TDL-04-max, TDL-04-min, and TDL-04. ETSI 11 ETSI EN 301

47、 469-5 V1.l.l (2000-1 O) 2) not standardized: - Those not defined in the standard, i.e. for execution use, e. g. a timer waiting for a response. These timers begin with the prefix “T-“, followed by a string in lowercase letters. EXAMPLE 2: Tresp represents a timer for controlling the response time o

48、f the IUT. 6.1 .I .IO ASP type definitions The identifier of an ASP uses exactly the nearest name as the name defined in the specifications. It is written in uppercases, finishing by an underscore character (I-I), and three capital letters indicating whether it is a request, an indication, a respons

49、e or a confirmation primitive. EXAMPLE: DL-RELEASE-REQ for an ASP containing a layer 3 release request passed to layer 2; MAC-DATA-REQ for an ASP containing a layer 2b PDU passed to layer 2a. 6.1 .I .I 1 PDU type definitions The identifier of a PDU is given in a string in uppercase letters, which represents the layer message. EXAMPLE 1: RR for the Receive Ready layer 2 message; DISCONNECT for the DISCONNECT layer 3 message. Where the message is a composite word, an underscore character (I-“) appears in the string. EXAMPLE
