49、 Library For this interworking ATS there are 2 applicable base protocols: a) SIP protocol (10); and b) ISDN protocol (ITU-T Recommendation Q.931 8 series, plus associated standards for supplementary services etc.). Since e.g. the data structures of these 2 base protocols are independent, and other objects like test cases are common, the TTCN-3 library modules are basically organized as: 1) SIP modules; 2) ISDN modules; 3) Common modules (generated for the present ATS); ETSI ETSI TS 186 001-2 V1.2.1 (2009
