空间数据和信息传输系统.接近1的空间链接协议.编码和同步传输内层

[中文适用范围]： 本推荐标准从以下几个方面定义了近距离-1链路的同步和信道编码方案：a) 向本规范用户提供的服务；b) 数据格式；以及 c) 生成和处理数据格式所需的程序。本推荐标准未指定：a) 具体的实现或产品；b) 执行这些程序所需的方法或技术；或 c) 配置和控制协议所需的管理活动。 [外文原描述]： ISO 21459:2015 defines synchronization and channel coding schemes for Proximity-1 links in terms of: a) the services provided to the users of this specification; b) data formats; and c) the procedures performed to generate and process the data 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 protocol. The Coding and Synchronization Sublayer is part of the Data Link Layer. The rest of the Data Link Layer is defined in the separate CCSDS Recommended Standard entitled, Proximity-1 Space Link Protocol?Data Link Layer (reference [3]). The Physical Layer is defined in the separate CCSDS Recommended Standard entitled, Proximity-1 Space Link Protocol?Physical Layer (reference [4]).
