标准摘要
[中文适用范围]： 本国际标准规定了在 Q 参考点支持补充服务和附加基本呼叫能力的功能协议。 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。 通用功能协议是 B-QSIG 信令系统的一部分。 本国际标准中规定的过程可以与承载连接相关（承载相关）或在任何承载连接的上下文之外使用（与承载无关）。 本国际标准对个人附加基本呼叫能力和补充服务的应用超出了本国际标准的范围，应在指定个别功能的标准或专有规范中进行定义。 对本国际标准的所有一致性均基于 Q 参考点接口处的外部行为，即基于本国际标准中指定的正确消息结构和正确序列的生成。 通用功能协议基于 ATM 论坛规范 AF-CS-0102.000，该规范本身基于 ITU-T Rec.1 中规定的 DSS2 通用功能协议。 Q.2932.1 但扩展为允许非本地信息交换以及本地信息交换。 本国际标准适用于支持附加基本呼叫功能和/或需要 Q 参考点信令功能协议的补充服务的 PINX。 [外文原描述]： This International Standard specifies the functional protocol for the support of supplementary services and additional basic call capabilities at the Q-reference point. The Q-reference point exists between Private Integrated services Network eXchanges (PINX) connected together within a Private Integrated Services Network (PISN) and is defined in ISO/IEC 11579-1. The generic functional protocol is part of the B-QSIG signalling system. The procedures specified in this International Standard can be used in association with a bearer connection (bearer-related) or outside the context of any bearer connection (bearer-independent).The application of this International Standard to individual additional basic call capabilities and supplementary services is outside the scope of this International Standard and should be defined in those standards or proprietary specifications that specify the individual capabilities. All conformance to this International Standard is based on the external behaviour at the interface at the Q-reference point, i.e. on the generation of the correct message structure and in the proper sequence as specified in this International Standard. The generic functional protocol is based on ATM Forum specification AF-CS-0102.000, which itself is based on the DSS2 generic functional protocol specified in ITU-T Rec. Q.2932.1 but extended to allow non-local information exchange as well as local information exchange. This International Standard is applicable to PINXs supporting additional basic call capabilities and/or supplementary services requiring the functional protocol for signalling at the Q-reference point.
