Abstract
Power is supplied to telecom equipment in DSLAM outdoor/remote cabinets with relatively short distances between the subscriber and the cabinet. All of the subscriber Customer Premises Equipment connected to the DSLAM each provide a portion of the required power to the remote cabinet via the telephone line connecting the DSLAM and the subscriber CPE. The CPE at the subscriber premises is already connected to power mains in the subscriber premises so, providing power, via the telephone line to the outdoor cabinet is relatively simple. The remote cabinet includes a circuit for receiving the power input from each subscriber and then distributing the power, required by the DSLAM load, equally among the subscribers.
