Abstract
In one embodiment, the method includes inserting an access node along a subscriber loop, the access node including a bypass switch for initially connecting a terminal segment of the subscriber loop to a network segment of the subscriber loop; operating a legacy communication service over the subscriber loop; and connecting a PSE for reverse power feeding of the access node and a new subscriber device for operating the new broadband communication service to the terminal segment. The method further includes, by the PSE, transmitting a sequence of successive command signals over the terminal segment prior to the insertion of the power feeding signal; by the access node, accumulating an electrical charge from the command signals; by the access node and by means of the so accumulated electrical charge, detecting a valid command signal in the sequence of successive command signals, and thereupon configuring the bypass switch for connecting the terminal segment to a transceiver and to a PSU; by the PSE, injecting the power feeding signal over the terminal segment for reverse power feeding of the access node; and operating the new broadband communication service over the terminal segment.
