Next level splits protocol testing in

As the protocol has different options, a
26、s for instance the use of presence check or the absence of presence check, there are several ways to reach a given state. The preamble has to be chosen according to the IUT capabilities and the implemented options. ETSI 11 ETSI TS 100 394-4-3 V1.l.l (2000-10) 5.1.2.1 Preamble idleto-TX-occupation: F

It appears that some selection expressions are quite complex, mainly the ones used for the MAC layer test suite, as they are based on a rather long combination of PICS statements. To ease the readability of the test purposes,
34、 these complex selection expressions are replaced by generic names which are defined here, and which represent by definition the selection expression themselves.
