1. A method of synchronization of a powerline network for a plurality of devices, comprising the steps of:

  • providing the plurality of devices each having a powerline modem and a clock circuit for synchronizing a data rate, the powerline modem permitting data transmission between the plurality of devices over the powerline network on data carriers;

    transmitting a synchronization signal over the powerline network, the synchronization signal being a carrier operating at a frequency different from the data carriers, the synchronization signal providing each of the plurality of devices a time reference to synchronize the data rate; and

    each of the plurality of devices sounding off during an assigned time slot.
