Works very well. Taken to protect my FreeBox to surge back through the telephone cable. My Freebox, the ADSL2 + line passes through EATON this case, synchronize the same rate as before without: no loss (sy chro to 9.86 Mb / s, or 1,23Mo / s at 2500m from the DSLAM). Very good product. Not being compatible CPL announced by the manufacturer, I use the power outlet of the box to secure EATON devices other than my FreeBox. My Freebox Server is on another lightning protection socket-compatible PLC as well connected to the Freebox TV Player.
