An interconnect-power-manager cooperates and communicates signals with an integrated-circuit-system-power-manager in the integrated-circuit. More in particular, the invention is related to handsets of the clamshell or flip-phone type. Further, information continues to be distributed among the NCPs even if a break occurs in a segment of fiber in the network. They are inputted to the estimating means as inputs, thereby estimating individual electricity consumption of the electric appliances.
