Zusammenfassung:	It enables the bi-directional communication between a head-end and a plurality of users through the electricity network, and it is characterized in that it allows to establish a low and high speed communication in order to provide multiple high-quality services to the users. It comprises means to accomplish a share of the network in time, frequency and/or in multiple access by means of orthogonal frequency division (OFDMA).
