ISO/IEC 13874:2003规定了用于支持在专用综合业务网络(PISN)内连接在一起的专用综合业务网络交换机(PINX)之间的Q参考点处的路径替换附加网络特征(ANF-PR)的信令协议。ANF-PR是一种应用于已建立呼叫的特征，允许该呼叫在PINX之间的连接被新的连接替换。Q参考点在ISO/IEC 11579-1中定义。根据ETS 300 387中规定的方法，分三个阶段制定服务规范。ISO/IEC 13874:2003包含Q参考点的第3阶段规范，并满足ISO/IEC 13863中第1阶段和第2阶段规范确定的要求。用于ANF-PR的信令协议在用于基本电路交换呼叫控制的信令协议之上操作，如在ISO/IEC 11572中所规定的，并且使用用于控制补充呼叫的通用过程的某些方面。ISO/IEC 11582中规定的服务。ISO/IEC 13874:2003还规定了额外的信令协议要求，以支持ANF-PR与其他补充服务和ANF之间的Q参考点处的交互。ISO/IEC 13874:2003适用于可以互连以形成PISN的PINX。
ISO/IEC 13874:2003 specifies the signalling protocol for the support of the Path Replacement additional network feature (ANF-PR) at the Q reference point between Private Integrated services Network eXchanges (PINXs) connected together within a Private Integrated Services Network (PISN).
ANF-PR is a feature which applies to an established call, allowing that call's connection between PINXs to be replaced by a new connection.
The Q reference point is defined in ISO/IEC 11579-1.
Service specifications are produced in three stages and according to the method specified in ETS 300 387. ISO/IEC 13874:2003 contains the stage 3 specification for the Q reference point and satisfies the requirements identified by the stage 1 and stage 2 specifications in ISO/IEC 13863.
The signalling protocol for ANF-PR operates on top of the signalling protocol for basic circuit switched call control, as specified in ISO/IEC 11572, and uses certain aspects of the generic procedures for the control of supplementary services specified in ISO/IEC 11582.
ISO/IEC 13874:2003 also specifies additional signalling protocol requirements for the support of interactions at the Q reference point between ANF-PR and other supplementary services and ANFs.
ISO/IEC 13874:2003 is applicable to PINXs which can interconnect to form a PISN.
