Header equipment, as well as system and procedure for the fault-tolerant connection of broadband terminals on power lines to a backbone network using this header equipment

摘要

Header equipment to provide communication between broadband terminals on power lines (Breitband Powerline), BPL terminals, and a backbone network, presenting the header equipment (HE1, HE1 ', HE2) a BPL interface for communication with the BPL terminals (BE1, BE2) and an uplink interface for communication with the backbone network, connecting the BPL terminals (BE1, BE2) to the header equipment (HE1, HE1 ', HE2) via the BPL interface, managing the header equipment (HE1, HE1 ', HE2) in a normal mode connected BPL terminals (BE1, BE2) connected and transmitting data packets between the connected BPL terminals (BE1, BE2) and the backbone network, characterized by that the header equipment (HE1, HE1 ', HE2) presents means to detect the status of the connection to the backbone network and why the header equipment (HE1, HE1') is configured to deactivate the management function for the terminals BPL (BE1, BE2) connected to the detects Failure to connect to the backbone network, which cancels a BPL cell managed by the header device (HE1, HE1 ').
