Tests for the other supplementary services have not been specified. The tests are split into four categories according to supplementary service. Table 16-4 shows the test categories and the tests therein. | ISUP Supplementary Services Testing The ISUP supplementary test specification is found in ITU 91 . The purpose of the tests is to ensure validation and compatibility of an SP s user-to-user signaling UUS closed user group CUG calling line identification CLI and connected line identification COL supplementary services according to ITU 69 to a reasonable but not exhaustive degree. Tests for the other supplementary services have not been specified. The tests are split into four categories according to supplementary service. Table 16-4 shows the test categories and the tests therein. Table 16-4. Test Categories and Test Numbers in Category Test Number s Total User-to-User Signaling UUS implicit request 6 Closed User Group CUG decentralized 9 Calling Line Identification CLI 16 Connected Line Identification COL - 15 Totals 46 The remainder of this section provides an explanation of three of these tests and . These numbers refer to the test numbers allocated in . Test Configuration Only a single test configuration is used the same one that is used in ISUP basic call control testing. The test configuration consists of SP A and SP B. SP A is the device under test DUT while SP B is the Tester or an SP whose ISUP protocol has been verified. Links and bearers are provided between the two SPs. The test specification makes use of stimulus in relation to creating certain conditions. Example 1 CUG Call with Outgoing Access Allowed and Sent Test This test is to check that the DUT can correctly send the parameters that are necessary for a CUG call with outgoing access allowed. It is used for both validation and compatibility testing purposes. The DUT should generate an IAM that contains the .
