The criteria applied include thefollowing:-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 from the TP is not considered.5.2Network TPs for CCNRAll PICS items referred to in this subclause are as specified in EN 301 065-2 [2] unless indicated otherwise by anothernumbered reference.Unless specified:-The messages indicated are valid and contain at least the mandatory information elements and possibly optionalinformation elements.-The information elements indicated are valid and contain at least the mandatory parameters and possibly optionalparameters.SIST EN 301 065-5:2001

The criteria applied include thefollowing:-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 from the TP is not considered.5.2Network TPs for CCNRAll PICS items referred to in this subclause are as specified in EN 301 065-2 [2] unless indicated otherwise by anothernumbered reference.Unless specified:-The messages indicated are valid and contain at least the mandatory information elements and possibly optionalinformation elements.-The information elements indicated are valid and contain at least the mandatory parameters and possibly optionalparameters.SIST EN 301 065-5:2001
