Power line communication system having time server
First Claim
1. A system for bi-directional power distribution line communication, the system configured for data communication with an endpoint transceiver located at a customer premise, the system comprising:
- a timer server configured to retrieve the time; and
a substation controller in electrical communication with a power distribution line, the substation controller including a substation transceiver and substation programmable circuit, the substation programmable circuit including a substation clock, the substation programmable circuit programmed to,periodically retrieve the time from the time server to calibrate the substation clock to the retrieved time, andcontrol the substation transceiver to transmit the time to the endpoint transceiver, the time being transmitted to the endpoint transceiver over the power distribution line including at least one transformer that steps down a power signal from a first voltage to a second voltage wherein the endpoint transceiver is configured to communicate with the substation controller over a first sub-sub-channel of a plurality of sub-sub-channels separated within a sub-channel on the power distribution line, each of the plurality of sub-sub-channels configured to be respectively assigned to different ones of a plurality of endpoint transceivers, each of the sub-sub-channel configured to have a predetermined bandwidth.

Abstract
A system for bi-directional power distribution line communication. The system is configured for data communication with an endpoint transceiver located at a customer premise. The system comprises a time server in electrical communication with the transceiver, the time server configured to retrieve the time. A substation controller is in electrical communication with a power distribution line. The substation controller includes a transceiver and a programmable circuit. The programmable circuit includes a substation clock. The programmable circuit is programmed to periodically retrieve the time from the time server to calibrate the substation clock to the retrieved time, and to control the transceiver to transmit the time to the endpoint transceiver.
