摘要:
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.

A method of controlling power in a network element includes powering the network element by receiving power from a power communication medium and providing a telecommunication service over a service communication medium. The method further includes monitoring a primitive related to the powering of the network element and controlling the powering of the network element based on the primitive. More particularly, in an embodiment, the method comprises: powering the network element (404) by receiving power from a first power communication medium (406) at a first power interface (450); providing telecommunication service to the network element (404) via a first service interface (452) coupled to the first power communication medium (406); receiving at a second power interface (480) of the network element (404) power from the first power interface (450); applying power to a second power communication medium (416) from the second power interface (480), over which power from the network element (404) is supplied to a second network element (414); providing telecommunication service to the second network element (414) via a second service interface (453) coupled to the second power communication medium (416);exchanging management information with a source network element (402) coupled to the first power communication medium (406); and control powering of the network element (404) at least based on a primitive related to the power of the network element (404). Also in an embodiment, the network element comprises: a first service interface (452) configured to couple to a first power communication medium (406) that couples the network element (404) to a source network element (402) and over which telecommunication service is provided; a first power interface
