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.

Claim
1. A method performed by a remote device for providing power to the remote device connected to a network, the method comprising:
providing telecom service from the remote device to a plurality of subscriber's premises via a respective wireline, wherein each of the plurality of subscriber's premises is configured to connect electrical power from a power circuit in each of the plurality of subscriber's premises to the respective wireline, wherein the electrical power is converted from AC power to DC power and the DC power is a regulated DC power;
regulating an amount of power drawn from a subscriber's customer premises equipment based on a number of connected subscriber's customer premises equipment; and
receiving the regulated DC power via the respective wireline, wherein the remote device includes DC voltage regulation circuits to match electrical power requirements for the remote device.
2. The method of claim 1, wherein the remote device receives power from other sources.
3. The method of claim 1, wherein the telecom service is one of:
Asymmetric Digital Subscriber Line (ADSL),
