The set of signalling tests cover major areas of functionality on the air, Abis andA-interfaces, but is not designed to be a complete set of all the possible scenarios.The tests were designed from the set of core specifications that exist for the GSM network and anychanges that occur these specifications will be reflected in the test set documented within.2Normative referencesThis ETS incorporates by dated and undated reference, provisions from other publications. Thesenormative references are cited at the appropriate places in the text and the publications are listedhereafter.

A description of each follows.4.1Layer 2 signallingClause 5 contains the test set for LAPDm on the air interface.Clause 6 contains the test set for Internal Abis interfacing. This interface is optional for GSM PLMNoperators.Clause 7 contains the specification for the A-interface. This clause only contains a reference to therelevant CCITT, MTP recommendations.4.2Layer 3 signallingClause 8 contains the Base Station Signalling network aspects. It defines the BSS to be a black box andtests the relationship between the layer 3 messages on the air and A-interfaces.Clause 9 contains the Base Station Controller network aspects. The tests are primarily on the Abis and willbe used when one or more of the Base Station Transceivers in not co-located with the BSC.Clause 10 contains the Base Station Transceiver network aspects. The tests are primarily on the Abis andwill be used when one or more of the Base Station Transceivers is not co-located with the BSC.4.3Core SpecificationsTable 1: Core SpecificationsClauseSpecifications5GSM 04.06 [3]6GSM 08.56 [12], GSM 08.58 [13]7ITU-T Q.780 [23], ITU-T Q.781 [24], ITU-T Q.782 [25]8GSM 04.06 [3], GSM 04.08 [4], GSM 08.08 [10]9GSM 04.08 [4], GSM 08.08 [10], GSM 08.58 [13]10GSM 04.08 [4], GSM 08.08 [10], GSM 08.58 [13]11GSM 04.08 [4], GSM 08.08 [10], GSM 09.90 [14]SIST ETS 300 609-2 E1:2003

Page 16ETS 300 609-2 (GSM 11.23 version 4.6.1): June 19975Testing of Layer 2 (LAPDm) functions5.1ScopeThe tests in this subclause apply to an integrated BSS as well as to a BTS.The tests in this subclause are intended to verify the correct operation of the Layer 2 on the radio interface(LAPDm) on a per channel basis. The tests cover only the simplified protocol as described inGSM 04.06 [3]. Any interactions between Layer 2 on the radio interface and Layer 2 on the A-interface, orthe A-bis interface if supported by the BSS, as well as the performance under traffic load, are outside thescope of the tests described in this subclause. The Layer 2 tests described in this subclause for the BSSare to great extent similar to the radio interface Layer 2 conformance tests for the Mobile Station (seeGSM 11.10 [26]).It should be noted that tests under traffic load, e.g. when the BSS is exposed to a high number ofMS-originated or network originated calls or when Mobile Stations are performing handover at a high rate,are important to verify. It is, as also in the case of the MSC, up to the manufacturer to guarantee theoperation of the BSS under a certain traffic load. It is a national or operator specific matter as to whetherthis shall be verified or not and how to verify it. The verification of the operation under traffic loadconditions may differ depending of the internal structure of the BSS.Tests of other than the simplified LAPDm protocol are a national or operator specific matter.Only multiple frame operation will be tested. Transfer of unnumbered information is considered as testedimplicitly by Layer 1 and Layer 3 tests.5.2IntroductionBefore the LAPDm functions are tested, the Layer 1
