ISO 17810:2014从以下方面定义了CDMA扩频调制方案: a） 向本规范用户提供的服务； b） 传播代码格式；和 c） 生成和处理代码格式的过程。 它没有具体说明: a） 单个实现或产品； b） 执行程序所需的方法或技术；或 c） 配置和控制系统所需的管理活动。 ISO 17810:2014仅提供了与现有SNIP PN扩频调制系统的信号兼容性相关的参数要求（见C。 1). 还有许多其他类型的要求，与PN扩展调制信号格式无关，必须满足这些要求才能确保系统与现有SNIP硬件的兼容性。示例包括前向纠错编码格式、数据信号格式等。 ISO 17810:2014适用于机构标准的制定，以及交叉支援情况下CCSDS机构之间通过空间链路进行的未来数据通信。ISO 17810:2014包括国际标准的数据格式和程序的全面规范- 机构交叉支持。它既不是针对现有或未来任务可能实施的真实系统的规范，也不是针对这些系统的设计。 ISO 17810:2014将通过每个CCSDS机构的正常标准程序调用，并适用于预计将基于ISO 17810:2014所述能力提供交叉支持的任务。如果ISO 17810:2014的章节中明确规定了强制性能力，则当本文件用作交叉支持的基础时，必须实施强制性能力。 在允许或暗示选择的情况下，这些选择的实施取决于相关机构之间的具体双边交叉支持协议。

ISO 17810:2014 defines CDMA spread spectrum modulation schemes in terms of: a) the services provided to the users of this specification; b) spreading code formats; and c) the procedures performed to generate and process the code formats. It does not specify: a) individual implementations or products; b) the methods or technologies required to perform the procedures; or c) the management activities required to configure and control the system. ISO 17810:2014 provides only those parameter requirements relating to signal compatibility with the existing SNIP PN spread modulation systems (see C.1). There are many other types of requirements, not specifically related to PN spread modulation signal formats, which must be met to ensure system compatibility with existing SNIP hardware. Examples would include forward error correction coding format, data signal formats, etc. ISO 17810:2014 applies to the creation of agency standards and to the future data communications over space links between CCSDS agencies in cross-support situations. ISO 17810:2014 includes comprehensive specification of the data formats and procedures for inter-agency cross support. It is neither a specification of, nor a design for, real systems that may be implemented for existing or future missions. ISO 17810:2014 is to be invoked through the normal standards programs of each CCSDS agency, and is applicable to those missions for which cross support based on capabilities described in ISO 17810:2014 is anticipated. Where mandatory capabilities are clearly indicated in sections of ISO 17810:2014, they must be implemented when this document is used as a basis for cross support. Where options are allowed or implied, implementation of these options is subject to specific bilateral cross-support agreements between the agencies involved.
