信息技术 系统间远程通信和信息交换 专用综合业务网 编址

[中文适用范围]： 本国际标准定义了处理网络地址的要求，以识别使用或提供专用综合服务网络（PISN）提供的电信服务的实体。 该国际标准涵盖编号，包括支持专用编号计划、开放系统互连的网络服务接入点寻址（OSI NSAP 寻址）以及子寻址支持的要求。 本国际标准适用于具有宽带和窄带功能（PINX）的专用综合业务网络交换机以及连接到PINX接入的终端。 PINX 对公共 ISDN 提供的私人编号计划支持补充服务的任何使用均不属于本国际标准的范围。 尽管本国际标准没有明确描述其对位置无关（移动）可寻址实体的应用，但并不排除这种应用。 [外文原描述]： This International Standard defines the requirements for the handling of network addresses for the identification of entities which use or provide telecommunication services offered by Private Integrated Services Networks (PISNs). This International Standard covers numbering, including the requirements for the support of a Private Numbering Plan, the addressing of network service access points for open systems interconnection (OSI NSAP addressing), and the support of subaddressing. This International Standard is applicable to Private Integrated Services Network Exchanges with broad-band and narrow-band capabilities (PINX) and to terminals to be attached to the access of PINXs. Any use by a PINX of the Support of Private Numbering Plans supplementary service provided by a public ISDN is outside the scope of this International Standard. Although this International Standard does not explicitly describe its application to location-independent (mobile) addressable entities, this application is not precluded.
