IEC 62488的本部分适用于用于传输的电力线载波终端和网络 电力网络信息，包括超高压、高压和中压（EHV/HV/MV） 在16 kHz至1 MHz的频率范围内使用数字和可选模拟调制系统的电力线（另见IEC 62488-1）。 在许多国家，电力线载波（PLC）信道是公用事业公司拥有的电信系统的重要组成部分。通常通过PLC通道布线的电路也可以 通过使用不同传输介质（如点对点无线电、光通信）的信道进行路由 光纤或开路。 因此，终端之间使用的输入和输出接口 通讯系统是标准化的。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This part of IEC 62488 applies to power line carrier terminals and networks used to transmit information over power networks including extra high, high and medium voltage (EHV/HV/MV) power lines using both digital and optionally analogue modulation systems in a frequency range between 16 kHz and 1 MHz (see also IEC 62488-1). In many countries, power line carrier (PLC) channels represent a significant part of the utility-owned telecommunication system. A circuit normally routed via a PLC channel can also be routed via a channel using a different transmission medium such as point to point radio, optical fibre or open wire circuit. It is therefore important that the input and output interfaces that are used between terminals in the communication system are standardised.All current amendments available at time of purchase are included with the purchase of this document.
