35、e generated as a result of an analysis of the base standard and the PICS specification EN 300 052-2 121. The criteria applied include the following: - - only the requirements from the point of view of the T or coincident S and T reference point are considered; whether or not a test case can be built

36、 from the TP is not considered. ETSI 9 6.1.5 Test of call states EN 300 052-5 V1.2.4 (1 998-06) Many TPs include a reference to the IUTs 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 stat

37、e. Ensuring that the IUT is in a particular call state shall be realized by following the procedures described in subclause 5.8.10 of EN 300 403-1 7. According to these procedures, the IUT on receipt of a STATUS ENQUIRY message, shail respond with a STATUS message indicating, in the third octet of t

38、he 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 structu

39、re of the TPs and to improve the readability. 6.2 Network TPs for MSN Ali PICS items referred to in this subclause are as specified in EN 300 052-2 2 unless indicated otherwise by another numbered reference. 6.2.1 Called user interface MSN-Nol-001 subclause 9.2.1 optional Ensure that the IUT in the
