1. A method, comprising:

  • requesting a phase-related response from an end-point that does not know its phase in a polyphase power source system;

    receiving the phase-related response from the end-point, the phase-related response configured to relay an identification of the end-point and related phase information without indicating an actual phase of the end-point;

    correlating the phase information of the phase-related response to a known phase of a known-phase device; and

    identifying the actual phase of the end-point based on the correlation, whereinthe phase-related response is a message transmitted on a particular power-line of the polyphase power source system, the related phase information of the phase-related response being the fact that the message was transmitted on the particular power-line.
