Groups are organized according to the TSS.Additional references are added to identify the actual test suite and whether it applies to the network or theuser (see table 1).Table 1: TP Identifier naming convention schemeIdentifier:___=layer + type of IUT:e.g. "L3U" for layer 3, IUT = user=call state:e.g. U10 for Active call state=group:one character field representing the groupreference according to TSSV:Valid stimulusI: Inopportune stimulusS:Syntactically invalid stimulusA:Active test case=sequential number:(001-999)6.1.2Source of TP definitionThe TPs are based on ETS 300 403-1 [1] and ETS 300 403-2 [2].SIST ETS 300 403-4:1998



Page 15ETS 300 403-4: January 19976.1.3TP structureEach TP has been written in a manner which is consistent with all other TPs. The intention of this is tomake the TPs more readable and checkable. A particular structure has been used which is illustrated intable 2. This table should be read in conjunction with any TP, i.e. please use a TP as an example tofacilitate the full comprehension of table 2.Table 2: Structure of a single TPTP partTextExampleHeader tabsee table 1 tabsubclause 2.3.4 or new TCTC10822 (see note 2)StimulusEnsure that the IUT in theU00, U10, etc. see below for message structureon receipt of a XXXX message(see note 3)or to request a .Reactionsends, saves, does, etc.using en bloc sending, etc.if the action is sending

In these cases theTP includes the requirement to ensure that the IUT has entered this particular final call state. Ensuringthat the IUT is in a particular call state shall be realized by following the procedures described insubclause 5.8.10 of ETS 300 403-1 [1]. According to these procedures, the IUT on receipt of a STATUSENQUIRY message, shall respond with a STATUS message indicating, in the t
