Abstract
A system for providing subscriber line power to an auxiliary device may include a primary communications device, a secondary communications device, and an auxiliary device. The primary communications device and the secondary communications device may be connected to opposite ends of at least one subscriber line. The auxiliary device may be connected to the secondary communications device. The auxiliary device may be powered by the primary communications device via the subscriber line and the secondary communications device. A power capacity metric of the at least one subscriber line may be determined. An operating power metric of the secondary communications device may be determined. A power budget may be calculated from the power capacity metric and the operating power metric. The power budget may be enforced. For example, the secondary communications device may limit power to the auxiliary device to enforce the power budget.
