本国际标准规定了附加网络特征公共信息（ANF-CMN），适用于专用综合业务网（PISN）支持的各种基本业务。ISO/IEC 11574规定了基本服务。 ANF-CMN是一种额外的网络功能，它可以通过PISN在代表连接两端的实体之间交换公共信息。该公共信息是与连接一端的用户或设备相关的杂项信息的集合，包括以下一项或多项:特征标识符、参与方类别、设备标识。 当实体接收到该信息时，该信息可用于任何目的，例如作为向本地用户或另一网络指示的基础，或用于过滤功能请求。 根据ITU-T Rec.I.130中描述的方法，额外的网络特性规范分三个阶段产生。本国际标准包含ANF-CMN的第1阶段和第2阶段规范。第1阶段规范（第6条）规定了该特性用户看到的附加网络特性。第2阶段规范（第7条）确定了附加网络功能中涉及的功能实体以及它们之间的信息流。

This International Standard specifies the additional network feature Common Information (ANF-CMN), which is applicable to various basic services supported by Private Integrated Services Networks (PISN). Basic services are specified in ISO/IEC 11574. ANF-CMN is an additional network feature which enables the exchange of Common Information between entities acting on behalf of the two ends of a connection through a PISN. This Common Information is a collection of miscellaneous information that relates to the user or equipment at one end of a connection and includes one or more of the following: Feature Identifiers, Party Category, Equipment Identity. This information, when received by an entity, can be used for any purpose, e.g. as the basis for indications to the local user or to another network or in order to filter feature requests. Additional network feature specifications are produced in three stages, according to the method described in ITU-T Rec. I.130. This International Standard contains the stage 1 and stage 2 specifications of ANF-CMN. The stage 1 specification (clause 6) specifies the additional network feature as seen by users of the feature. The stage 2 specification (clause 7) identifies the functional entities involved in the additional network feature and the information flows between them.
