标准摘要
[中文适用范围]： 对于支持 CONS 的协议，CONS 的抽象原语和参数与协议的实际元素之间必须存在映射。 对于X.25分组层协议(PLP)，该标准的主体为使用虚拟呼叫的X.25/PLP-1984提供了这样的映射。 还提供 CONS 原语和参数到 X.25/PLP-1980 以及 SNDCP 的映射。 这些映射适用于 X.25 VC 服务。 指定两组过程，其中描述了三类实现。 [外文原描述]： For a protocol to support the CONS, there must be a mapping between the abstract primitives and parameters of the CONS and the real elements of the protocol. For the X.25 Packet Layer Protocol (PLP), the main body of this standard provides such a mapping for the X.25/PLP-1984 using Virtual Calls. Also provides a mapping of the CONS primitives and parameters to the X.25/PLP-1980 plus an SNDCP. These mappings apply to the X.25 VC service. Specifies two sets of procedures from which three classes of implementation are described.
