20、ements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification ETSI TS 103 261-1 2. 4.1.3 TP structure Each TP has been written in a manner which is consistent with all other TPs. The intention of this is to make the TPs more readable and checka

This table should be read in conjunction with any TP, i.e. please use a TP as an example to facilitate the full comprehension of table 2.
