ISO/IEC 9314的本部分包含光纤分布式数据接口的抽象测试套件 （FDDI）令牌环站管理（SMT）层协议。SMT协议是广泛的，非常有用 复杂的在制定过程中，该议定书被分为六个不同的领域。这些地区 处理物理连接管理（PCM）、实体协调管理（ECM）环 管理（RMT）、配置管理（CMT）、基于帧的管理（FBM）和 管理信息库（MIB）。 该SMT ATS沿着相同的边界划分，但PCM和ECM除外 合二为一。这两个概念一起测试。用于描述的形式化描述语言 抽象测试套件（ATS）的开发是树形和表格组合符号（TTCN）和 在ISO 9646框架中定义。TTCN用于高层协议测试，需要 使用谨慎协议数据单元（PDU）。TTCN符号用于RMT的测试用例中， FBM和MIB。它不能用于PCM、ECM和CFM。这三个协议使用线路状态作为 传递信息的方法。 TTCN（P）在结构上与TTCN相似，但将范式从PDU更改为线态。A. TTCN（P）概念的描述见第6节PCM开头部分。

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 very complex. In the development process, the protocol was broken into six separate areas. Those areas dealt with Physical Connection Management (PCM), Entity Coordination Management (ECM) Ring Management (RMT), Configuration Management (CMT), Frame Based Management (FBM) and Management Information Base (MIB). This SMT ATS is divided along the same boundaries, with the exception that PCM and ECM are combined. Those two concepts are tested together. The formal description language used for Abstract Test Suite (ATS) development is Tree and Tabular Combined Notational (TTCN) and is defined in ISO 9646Framework. TTCN is intended for higher layer protocol testing and requires the use 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 as the method of conveying information. The TTCN (P) is similar in structure to TTCN but changes the paradigm from PDUs to line states. A description of the concept of TTCN (P) can be found in the beginning of section 6, PCM.
