ISO/IEC 14908-3:2011规定了控制网络电源线（PL）通道，并作为ISO/IEC 14908-1的配套文件。它提供了开发PL物理网络所需的信息，以及通过该网络进行通信和共享信息的节点。 ISO/IEC 14908-3:2011涵盖了完整的物理层（OSI第1层），包括与介质访问控制（MAC）子层的接口和与介质的接口。它包括特定于PL信道类型的参数，即使这些参数可以在OSI层而不是第1层进行控制。ISO/IEC 14908-3:2011还为电力线环境提供了一套指导性物理和电气规范，以帮助开发该环境下的产品。

ISO/IEC 14908-3:2011 specifies the control network Power Line (PL) channel and serves as a companion document to ISO/IEC 14908-1. It presents the information necessary for the development of a PL physical network and nodes to communicate and share information over that network. ISO/IEC 14908-3:2011 covers the complete physical layer (OSI layer 1) including the interface to the Medium Access Control (MAC) sublayer and the interface to the medium. It includes parameters specific to the PL channel type, even though the parameters may be controlled at an OSI layer other than layer 1. ISO/IEC 14908-3:2011 also provides a set of guideline physical and electrical specifications for the power line environment as an aid in developing products for that environment.
