25、gy As the base specification in ETSI TS 136 413 1 contains no explicit requirements for testing, the TPs were generated as a result of an analysis of the base standard and the PICS specification ETSI TS 103 497-1 2. 5.1.3 TP structure Each TP has been written in a manner which is consistent with all
26、 other TPs. The intention of this is to make the TPs more readable and checkable. A particular structure has been used which is illustrated in Table 2. Table 2 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. ETSI ETSI TS
