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:___=suiteL2 = layer 2=sideU = userN = networkC = combined (user and network)=procedure categoryLLayer managementDData control=data link entity statee.g.:70, 4, 81, etc.=groupone character representing group reference according to TSS:V:Valid stimulusI:Inopportune stimulusS:Syntactically stimulusT:timersC:counters=sequential number(1-99)6.1.2Source of TP definitionThe TPs are based on ETS 300 402-2 [1].SIST ETS 300 402-6:1998

Page 12ETS 300 402-6: 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 5.3.1 [opt.]table D.1/2-1 (see note 2) or new TCTC11001 (see note 3)StimulusEnsure that the IUT in the

The use of primitives is considered to be not acceptable.SIST ETS 300 402-6:1998
