标准范围
本国际标准规定了使用电路的一对按需PINX间连接的映射功能模式同时提供公共ISDN的基本业务和补充业务用户对用户信令（业务3）。为了将专用综合服务网络交换机（PINX）连接到另一个PINX，需要映射功能使C参考点的特定接口适应Q参考点的应用程序。因此，映射函数在C参考点对接口进行物理调整。映射函数还提供了Q参考点处的用户信道和信令信息到C参考点处的适当信道或时隙指向ISO/IEC 11579-1中定义了C和Q参考点。在Q参考点，映射为用户通道提供64 kbit/s服务，为用户通道提供分组模式服务信号通道。承载条件不在本国际标准的范围内，但为Q参考点处的信令信道。场景管理不在本国际标准的范围内。本国际标准适用于PINX，PINX可以相互连接以形成专用综合业务网络（PISN）支持Q参考点的信令协议。
This International Standard specifies the mapping functions for a pair of on-demand inter-PINX connections using a circuitmode basic service and the supplementary service User-to-User Signalling (service 3) of a public ISDN at the same time.In order to connect a Private Integrated Services Network Exchange (PINX) to another PINX, mapping functions are requiredto adapt the specific interfaces at the C reference point to the application at the Q reference point. As such, mapping functionsprovide for physical adaptation to the interface at the C reference point. Mapping functions also provide for the mapping ofuser channels and signalling information at the Q reference point to the appropriate channels or timeslots at the C referencepoint.The C and Q reference points are defined in ISO/IEC 11579-1.At the Q reference point the mappings provide a 64 kbit/s service for user channels and a packet mode service for thesignalling channel. Bearer conditioning is outside the scope of this International Standard, except for providing the layer 2 forthe signalling channel at the Q reference point.Scenario management is outside the scope of this International Standard.This International Standard is applicable to PINXs which can be interconnected to form a Private Integrated Services Network(PISN) and which support signalling protocols at the Q reference point.
