ANSI C12标准委员会在全国范围内采用了IEC 62056-8-20 Ed.1.0电能计量数据交换——DLMS/COSEM套件第8-20部分:邻里网络的网状通信模式。IEC 62056的本部分规定了DLMS/COSEM通信配置文件，可用于邻里网络（NN）为网状网络的智能计量系统。该配置文件可视为IEC 62056-9-7:2013中规定的UDP/IP通信配置文件的改编和扩展。在该标准中，PHY和MAC层超出了范围。本技术规范规定了使用网状NNs的大规模AMI有效运行所必需的一些功能。

ANSI C12 Standards Committee makes an identical national adoption of IEC 62056-8-20 Ed. 1.0 Electricity Metering Data Exchange - The DLMS/ COSEM Suite Part 8-20: Mesh Communication Profile for Neighbourhood Networks. This part of IEC 62056 specifies a DLMS/COSEM communication profile that can be used in a smart metering system in which the Neighbourhood Networks (NN) are mesh networks. This profile may be considered as an adaptation and extension of the UDP/IP communication profile specified in IEC 62056-9-7:2013. As in that standard, the PHY and MAC layers are out of the Scope. This Technical Specification specifies a number of features essential to the efficient operation of a large scale AMI using mesh NNs.
