Groups are organized according to the TSS. Additional references are added to identify the actual test suite (see table 1). Table 1: TP identifier naming convention scheme Identifier: __

5.1.2 Source of TP definition The TPs are based on EN 301 068-1 [1]. SIST EN 301 068-3 V1.2.1:2003



ETSI ETSI EN 301 068-3 V1.2.1 (2002-08) 9
5.1.3 Test strategy As the base standard EN 301 068-1 [1] contains no explicit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification EN 301 068-2 [2]. The TPs are only based on conformance requirements related to the externally observable behaviour of the IUT and are limited to conceivable situations to which a real implementation is likely to be faced (see ETS 300 406 [6]). 5.1.4 Test of call states Many TPs include a reference to the IUT's final call state after the realization of the TP. In these cases the TP includes the requirement to ensure that the IUT has entered this particular final call state. Ensuring that the IUT is in a particular call state shall be realized by following the procedures described in clause 5.6.11 of EN 300 443-1 [7]. According to these procedures, the IUT on receipt of a STATUS ENQUIRY message, shall respond with a STATUS message indicating, in the fifth octet of the Call state information element, the current call state of the IUT. This exchange of messages is not mentioned explicitly in each TP but is considered to be implicit in the reference to the final call state. This way of phrasing the TPs has been used to avoid over-complicating the text and structure of the TPs and to improve the readability. 5.1.5 Validity of Test Purposes The test purposes below are valid only for IUTs that do not use the negotiation procedure defined in EN 301 067-1 [8]. These procedures are tested in the test specification standards related to EN 301 067-1 [8]. 5.2 TPs for the ATM transfer capability and traffic parameter indication, user All PICS items referred to in this clause are as specified in EN 301 068-2 [2] unless indicated otherwise by another numbered reference. Unless specified: • the messages indicated are valid and contain at least the mandatory information elements and possibly optional information elements; • the information elements indicated are valid and contain at least the mandatory parameters and possibly optional parameters. 5.2.1 Signalling procedures at the coincident SB/TB and at the TB reference points NOTE: Unless otherwise specified, the connection defined by the requested ATM traffic descriptor is available for use. 5.2.1.1 Additional parameter procedures at the originating interface Test purposes for EN 301 068-1 [1]. 5.2.1.1.1 Sustainable Cell Rate parameter set (01) Test purposes for EN 301 068-1 [1] (ITU-T Recommendation Q.2961.1 [10], modified). NOTE: In the following test purpose Sustainable cell rate parameter set includes Sustainable cell rate and Maximum Burst size. SIST EN 301 068-3 V1.2.1:2003
