Abstract: Technique is proposed for managing total power consumption in an access network comprising two or more interface modules serving a plurality of subscriber lines, the technique comprises performing a study of real power consumption of the subscriber lines in the access network on a line-to-line basis, correlating results of the study with inventory information concerning allocation of the subscriber lines to the interface modules and power consumption ensured by said modules to the lines and, based on the correlation, assessing optimality of allocation of the subscriber lines to the interface modules.

Abstract: A communication system comprising: a first multiplexing/demutliplexing stage positioned at a first locality and connected to a telephone interchange; a plurality of second multiplexing/demultiplexing stage positioned in a plurality of second localities apart from said first locality; a communication link, such as a transmission line or radio link which connects said first multiplexing/demultiplexing stage to each of said second multiplexing/demultipleg stages; and a plurality of subscribers lines connected to each of a plurality said second multiplexing/demultiplexing stages.
