适用范围：This part of ISO/IEC 9314 contains the Abstract Test Suites for the Fiber Distributed Data Interface(FDDI) token ring Station Management (SMT) layer protocol. The SMT Protocol is extensive and verycomplex. In the development process, the protocol was broken into six separate areas. Those areasdealt with Physical Connection Management (PCM), Entity Coordination Management (ECM) RingManagement (RMT), Configuration Management (CMT), Frame Based Management (FBM) andManagement Information Base (MIB).This SMT ATS is divided along the same boundaries, with the exception that PCM and ECM arecombined. Those two concepts are tested together. The formal description language used forAbstract Test Suite (ATS) development is Tree and Tabular Combined Notational (TTCN) and isdefined in ISO 9646Framework. TTCN is intended for higher layer protocol testing and requires theuse of discreet Protocol Data Units (PDUs). The TTCN notation is used in the test cases for RMT,FBM and MIB. It cannot be used for PCM, ECM and CFM. These three protocols use line states asthe method of conveying information.The TTCN (P) is similar in structure to TTCN but changes the paradigm from PDUs to line states. Adescription of the concept of TTCN (P) can be found in the beginning of section 6, PCM.
