涵盖使用半双工和双工链路协议的异步数据传输，该协议使用窗口大小为1的消息传输。 为远程控制应用程序指定由链路加物理层提供的服务的基本要求。特别地，它规定了关于满足指定数据完整性要求的可变长度和字段长度的数据帧的编码、格式化和同步的标准。 该出版物与智能电网高度相关。

Covers asynchronous data transmission with half duplex and duplex link protocols operating with window size one for message transfers. Specifies the basic requirements for services to be provided by the link plus physical layers, for telecontrol applications. In particular it specifies standards on coding, formatting and synchronizing data frames of variable and filed lengths which meet specified data integrity requirements.
