20、 TP is not considered. 6.1.5 Test of call states 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 state. Ensuring that the IUT is in a particular cal

21、l state shall be realized by following the procedures described in clause 5.8.10 of EN 300 403-1 6. According to these procedures, the IUT on receipt of a STATUS ENQUIRY message, shall respond with a STATUS message indicating, in the third octet of the Call state information element, the current cal

22、l 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. NOTE
