22、C interface is not accessible it is also possible to perform the test of the AS using any network-to-network interface (NNI) (i.e., Mw, Mw, Mx) (see Figure 6.1.1-2).

ITU-T Q.4011.2 (08/2016) 7 Test purposes 7.1 Introduction For each test requirement a test purpose (TP) is defined. 7.1.1 TP naming convention Test purposes (TPs) are numbered, starting at 001, within eac
24、h group. 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 the user (see Table 1). Table 1 TP identifier naming convention scheme Identifier: _ = supplementary service: e.g. “CUG“ = type of IUT: U Use
25、r equipment N Network entity = group 2 digit field representing group reference according to TSS = sequential number (001-999) 7.1.2 Test strategy As the base standard ITU-T Q.3627 v.1 contains no explicit requirements for testing, the TPs were generated as a result of an analysis of the base standa
