scope:

This standard applies to Single Sideband (SSB) Power Line Carrier (PLC) Terminals used to transmit information over High Voltage (HV) Lines. The object of this standard is to establish recommended values for characteristics input and output quantities of single sideband PLC terminals and the definitions essential for an understanding of these recommendations. All the test verifying the requirements shall be considered as type test as defined in the International Electrotechnical Vocabulary (IEC 151-04-1). This standard defines two versions of the PLC equipment intended for two different applications: - standar terminal, i.e. equipment with a voice frequency side interface which offers transmission of a frequency band of 300 Hz to 3400 Hz on a four-wire basis plus signalling facilities. This equipment is capable, via analog interfaces, of being connected to networks that may consist of transmission equipment of different types and from different manufacturers. There may be facilities for additional point-to-point connections (e.g. a teleprotection connection) which may fall outside the frequency speech, data and teleprotection are present at the voice frequency side.
