标准摘要
[中文适用范围]： ISO/IEC 11579 的这一部分规定了专用综合业务网络交换 (PINX) 延长线的参考配置 (RC)，除了 ISO/IEC 11579 第 1 部分中规定的物理终端系统之外，还包括高级功能。 这种高级功能似乎依赖于应用程序，并且原则上可以以任何多重性和组合的形式出现，没有固定的功能分组分配，因此无法指示固定的参考点。 相反，ISO/IEC 11579 的本部分规定了与物理终端系统相关的功能分组组合和参考点分配的原则。 附录 A 中给出了功能分组和参考点分配的某些组合的示例。 无意要求 PINX 的任何特定实现，而只是为 PINX 功能规范提供指导。 该原理足以支持类似ISDN 的应用。 它可以扩展到支持非 ISDN 类应用程序。 [外文原描述]： This part of ISO/IEC 11579 specifies a reference configuration (RC) for the extension line of a private integrated services network exchange (PINX) including high level functions in addition to the physical termination system specified in part 1 of ISO/IEC 11579. Since such high level functions appear application dependent and can occur, in principle, in any multiplicity and combination, no firm allocation of functional groupings and thus no firm reference points can be indicated. Instead, the principles for combining functional groupings associated with the physical termination system and allocating reference points are specified in this part of ISO/IEC 11579. Examples for some combinations of functional groupings and the allocation of reference points are given in annex A. The principle is not intended to require any specific implementation of a PINX, but only to provide guidance for the specification of PINX capabilities. The principle is sufficient to support ISDN-like applications. It can be extended to also support non-ISDN-like applications.
