PCT No. PCT/FR97/01824 Sec. 371 Date Apr. 14, 1999 Sec. 102(e) Date Apr. 14, 1999 PCT Filed Oct. 13, 1997 PCT Pub. No. WO98/17013 PCT Pub. Date Apr. 23, 1998The invention concerns an interface device of bi-directional connection of current carrying low voltage/radio frequency. It includes a module for coupling currents carrying low voltage/radio frequency delivering in reception signals (rcp) representing reception of carrier currents, a first channel of currents carrying low voltage/radio frequency delivering a signal modulating radio frequency transmission (sme). A coupling device receives in transmission the modulating signal for transmitting a radio frequency signal (srfe) representing the carrier currents, and, in reception, a reception radio frequency signal (srfr) transmitted to a second channel of currents carrying low voltage/radio frequency. The second channel delivers signals (ecp) representing the carrier currents in transmission to the module for transmission of the low voltage line. The invention is useful for house automation and for managing subscriber services.
