Defines two versions of the PLC equipment intended for two different applications. 1) Standard 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. 2) Speech-plus terminal, i.e. equipment where specific interfaces for signals like speech, data and teleprotection are present at the voice frequency side.
