method for new broadband communication service, access node (100), power supply equipment (200), subscriber device and data communication system

摘要

The present invention relates to a method for providing a new broadband communication service (g.fast). In accordance with the embodiment of the invention, the method comprises inserting an access node (100) together with a subscriber loop (62), and the access node includes a bypass switch (150) for initially connecting a data segment. subscriber loop terminal (64) to a subscriber loop network segment (63); operate a legacy communication service (pots; vdsl2) through the subscriber loop; and connecting a pse (200) to the access node reverse power supply and a new subscriber device (70) to operate the new broadband communication service for the terminal segment. The method further comprises, by pse, transmitting a sequence of successive command signals (ac_cmd_signals) through the terminal segment prior to insertion of the power supply signal. The present invention also relates to an access node, a pse and a data communication system.
