[中文适用范围]： 该国际标准定义了用于在 Q 参考点控制补充服务和附加网络功能 (ANF) 的信令协议。 该协议是私人信令系统的一部分。 1 (PSS1)，非正式地称为 QSIG。 Q 参考点存在于专用综合业务网络 (PISN) 内连接在一起的专用综合业务网络交换机 (PINX) 之间，并在 ISO/IEC 11579-1 中定义。 适用于个别补充服务和 ANF 的详细程序超出了本国际标准的范围，并将由标准化服务的其他标准以及使用本国际标准中定义的功能的专有服务的各个制造商指定。 ISO/IEC 11572 定义了 Q 参考点电路交换呼叫控制的第 3 层协议。 本国际标准定义了附加协议程序，与 ISO/IEC 11572 中定义的协议程序结合使用，用于控制补充服务和 ANF。 注 1 – 附件 C 中提供了将这些通用功能程序应用于某些补充业务的典型示例，仅供解释和说明之用。 注 2 – 特定的补充服务和附加网络功能可能需要附加的信息传输机制，这些机制是特定于服务或功能的，超出了本国际标准的范围。 [外文原描述]： ISO/IEC 11582:2002 defines the signalling protocol for the control of Supplementary Services and Additional Network Features (ANFs) at the Q reference point. The protocol is part of Private Signalling System no. 1 (PSS1), known informally as QSIG. The Q reference point exists between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN) and is defined in ISO/IEC 11579-1. Detailed procedures applicable to individual supplementary services and ANFs are beyond the scope of ISO/IEC 11582:2002 and will be specified by other standards for those services which are standardised and by individual manufacturers for proprietary services using the capabilities defined in ISO/IEC 11582:2002. ISO/IEC 11572 defines the Layer 3 protocol for circuit-switched call control at the Q reference point. ISO/IEC 11582:2002 defines additional protocol procedures, to be used in conjunction with those defined in ISO/IEC 11572 for the control of supplementary services and ANFs. NOTE 1 Typical examples of the application of these generic functional procedures to some supplementary services are provided in annex C, for explanatory and illustrative purposes only. NOTE 2 Specific supplementary services and Additional Network Features may require additional information transfer mechanisms which are service or feature specific and are beyond the scope of ISO/IEC 11582:2002.
