ETSIETSI EN 300 497-5 V0.3.0 (1999-10)61ScopeThe present document contains the Abstract Test Suite (ATS) to test the Digital Enhanced CordlessTelecommunications (DECT) Data Link Control (DLC) layer.The objective of this test specification is to provide a basis for approval tests for DECT equipment giving a highprobability of air interface inter-operability between different manufacturer's DECT equipment.The ISO standard for the methodology of conformance testing (ISO/IEC 9646-1 [7], ISO/IEC 9646-2 [8],ISO/IEC 9646-3 [9] and ISO/IEC 9646-5 [10]) as well as the ETSI rules for conformance testing (ETS 300 406 [6] andETR 141 [13]) are used as basis for the test methodology.Test specifications for the Physical Layer (PHL), Medium Access Control (MAC) layer, and Network (NWK) layer areprovided in other the DECT standards.Annex A provides the Tree and Tabular Combined Notation (TTCN) part of this ATS.Annex B provides the Partial Protocol Implementation Extra Information for Testing (PIXIT) Proforma of this ATS.Annex C provides the Protocol Conformance Test Report (PCTR) Proforma of this ATS.2ReferencesThe following documents contain provisions which, through reference in this text, constitute provisions of the presentdocument.· References are either specific (identified by date of publication, edition number, version number, etc.) ornon-specific.· For a specific reference, subsequent revisions do not apply.· For a non-specific reference, the latest version applies.· A non-specific reference to an ETS shall also be taken to refer to later versions published as an EN with the samenumber.[1]EN 300 175-1: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI);Part 1: Overview".[2]EN 300 175-3: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI);Part 3: Medium Access Control (MAC) layer".[3]EN 300 175-4: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI);Part 4: Data Link Control (DLC) layer".[4]EN 300 175-6: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI);Part 6: Identities and addressing".[5]EN 300 175-7: "Digital Enhanced Cordless Telecommunications (DECT); Common Interface (CI);Part 7: Security features".[6]ETS 300 406: "Methods for Testing and Specification (MTS); Protocol and profile conformancetesting specifications; Standardization methodology".[7]ISO/IEC 9646-1: "Information technology - Open Systems Interconnection - Conformance testingmethodology and framework - Part 1: General concepts".[8]ISO/IEC 9646-2: "Information technology - Open Systems Interconnection - Conformance testingmethodology and framework - Part 2: Abstract Test Suite Specification".[9]ISO/IEC 9646-3: "Information technology - Open Systems Interconnection - Conformance testingmethodology and framework - Part 3: The Tree and Tabular Combined Notation (TTCN)".SIST EN 300 497-5 V0.3.0:2003

ETSIETSI EN 300 497-5 V0.3.0 (1999-10)84Abstract 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 Upper 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 differentATM;-this test method places the minimum limitations in the realization of conformance testing.The embedded variant of the remote test method provides sufficient control of the IUT DLC behaviour, through NWKlayer messages conveyed by DLC frames.Test SystemSUTUpperLayersIUTDECT DLC DECTNWK ?MAC ASPs!MAC ASPsLTDLC-PDUsin ASPs withMCEI and if necessary Service TypeMSAP -PCOFragmentationRecombinationSubset of Lc entityand FBx entitiesMAC-CO-DATA primitivesNWK-PDUsFor implicit test coordinationDECT PHL and radio communicationDECT MAC layerDECT MAC layerFigure 1: RS test Method embedded variantLT:A Lower Tester (LT) is located in a remote DECT test system. It controls and observes thebehaviour of the IUT.MSAP:MAC Service Access Point - A unique MSAP is defined at the DECT interface and used toexchange service data of the DLC protocol. To avoid the complexity of data fragmentation andrecombination testing, the Service Access Point (SAP) is defined below this functions of the DLClayer.PCO:The PCO for DLC layer testing is located on the MSAP. All test events at the PCO are specified interms of MAC Abstract Service Primitives (ASPs) and DLC layer Protocol Data Units (PDUs).Notional UT:No explicit upper tester (UT) exists in the system under test. Nevertheless, some network messagesare sent to the SUT for the need of the co-ordination procedures. The network layer of the SUT isused as a notional UT as defined in ISO 9646.SIST EN 300 497-5 V0.3.0:2003



ETSIETSI EN 300 497-5 V0.3.0 (1999-10)9The MSAP primitives are defined according to EN 300 175-3 [2] clause 8 and associated subclauses.5Untestable Test Purposes (TP)Due to the ATMs chosen for this ATS or other restrictions, the test purposes in table 1 have been identified as being inthe untestable category, and therefore have not been derived into final test case:Table 1: Untestable TPTest purposeReasonTPUV_000No procedure can be defined to determine if, after receiving the first UI frame, the IUTconsiders the class U link as established. It is an internal state of the DLC layer of the IUT.TPUV_001No procedure can be defined to determine if, after receiving an upward release, the IUTconsiders the class U link as released. It is an internal state of the DLC layer of the IUT.TPLC_002Prioritized queuing of broadcast message between normal and expedited data is not testable. Itis very difficult to define a procedure in the IUT to force it, to transmit normal and expediteddata in a sufficient short time. It is, also, very difficult for the tester to transmit normal andexpedited data in sufficient short time and to define a procedure to verify the correct order ofthe reception in the IUT.6ATS ConventionsThis clause describes the conventions applied to define the ATS and gives the naming conventions chosen for thedifferent elements of the ATS.The ATS conventions are intended to give a better understanding of the ATS but they describe also the conventionsmade for the development of the ATS, thus for any later maintenance purposes or further development of the ATS theconventions described in this clause shall be considered.The ATS conventions contain two subclauses, the naming conventions and the implementation conventions. The namingconventions describe the structure of the naming of all ATS elements. The implementation conventions describe thefunctional structure of the ATS.6.1Naming conventions6.1.1Declarations partThis subclause describes the naming conventions chosen for the elements of the ATS declarations part.6.1.1.1Test suite type and structured type definitionsThe test suite type and test suite structured type identifiers describe the information elements, and are written inuppercase:EXAMPLE:PROTOCOL_DISCRIMINATOR simple type.FILLSTRING structured type.6.1.1.2Test suite operations definitionsThe test suite operation identifiers are composed of string in lowercase letters starting by the uppercase string "TSO_".EXAMPLE:TSO_compute _checksum.SIST EN 300 497-5 V0.3.0:2003



ETSIETSI EN 300 497-5 V0.3.0 (1999-10)106.1.1.3Test suite parameter declarationsThe test suite parameter identifiers are composed of string in lowercase letters starting by the uppercase string "TSP_".EXAMPLE 1:TSP_window_size.If the test suite parameter references a PICS item, the letter "C" is added to the standard prefix.EXAMPLE 2:TSPC_pics_item_s23.If the test suite parameter references a PIXIT item, the letter "X" is added to the standard prefix.EXAMPLE 3:TSPX_pixit_item_2.Complete names as defined in the specifications are used.6.1.1.4Test case selection expression definitionsThe 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 logicalcombinations of the test suite parameters definitions.Certain test cases are selected only when the IUT is a FT part or a PT part. Therefore, to cover all test cases applicableto the implementation, it is necessary to change the relevant test suite parameter for running the desired test cases.6.1.1.5Test suite constant declarationsThe test suite constant identifiers are composed of string in lowercase letters starting by the uppercase string "TSC_".EXAMPLE:TSC_retry.Complete names as defined in the specifications are used.6.1.1.6Test suite variable declarationsThe test suite variable identifiers are composed of string in lowercase letters starting by the uppercase string "TSV_".EXAMPLE 1:TSV_count.Exception: If the test suite variable represents a system parameter or value, the name defined in the specifications isused.EXAMPLE 2:VR,VS.6.1.1.7Test case variable declarationsThe test case variable identifiers are composed of string in lowercase letters starting by the uppercase string "TCV_".EXAMPLE:TCV_cr_value.6.1.1.8PCO declarationsThe point of control and observation identifiers are composed of two or four capital letters, beginning with "L", as thereare only LTs.EXAMPLE:LMAC represents a PCO on MAC interface as LT in the test equipment.LDLC represents a PCO on DLC interface as LT in the test equipment.SIST EN 300 497-5 V0.3.0:2003



ETSIETSI EN 300 497-5 V0.3.0 (1999-10)116.1.1.9Timer declarationsTwo kinds of timers can be distinguished:1)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 margin 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_04.2)not standardized:Those not defined in the standard, i.e. for execution use, e. g. a timer waiting for a response. These timers beginwith the prefix "T_", followed by a string in lowercase letters.EXAMPLE 2:T_resp represents a timer for controlling the response time of the IUT.6.1.1.10ASP type definitionsThe identifier of an ASP uses exactly the nearest name as the name defined in the specifications. It is written inuppercases, finishing by an underscore character ("_"), and three capital letters indicating whether it is a request, anindication, a response 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.6.1.1.11PDU type definitionsThe 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 ("_") appears in the string.EXAMPLE 2:RELEASE_COMPLETE is the RELEASE COMPLETE layer 3 message.6.1.1.12Alias definitionsThese are used to make the sending and receiving of PDUs within ASPs more understandable when writing the dynamicpart of the test suite. This is done by giving the ASP an alias. The alias name indicates the PDU carried by the ASP andwhether it is sent or received by the tester.No alias are used in the test suite.SIST EN 300 497-5 V0.3.0:2003
