1. A data telecommunications network, comprising:
- a controller;
a first device;
a second device in data communication with the first device by way of a first cable;
a third device in data communication with the second device by way of a second cable; and
the controller configured to cause the third device to deliver power to the second device by way of the second cable upon a determination that the first device is not delivering power to the second device by way of the first cable;
wherein the second device comprises a rechargeable power store;
wherein the rechargeable power store of the second device is charged when the first device determines that the first device has surplus power.

Abstract
A method and apparatus for bidirectional provision of inline power over data telecommunications cabling permits power to be received at a local powered device (PD) from remote power sourcing equipment (PSE) via at least one conductor at a first time and power to be provided by the local device to the remote device or another device at a second different time.

12. A method of providing power in a data telecommunications network, comprising:
-
monitoring, at a controller, the delivery of power from a first device to a second device via a first cable, the second device being in data communication with the first device by way of the first cable, the second device including a rechargeable power store; determining, at the controller, that the first device is not delivering power to the second device by way of the first cable; and in response to determining, sending a signal, from the controller, directing a third device to deliver power to the second device by way of a second cable, the third device being in data communication with the second device by way of the second cable; and charging the rechargeable power store of the second device when the first device determines that the first device has surplus power.

13. A controller in a data telecommunications network, comprising:
-
circuitry configured to monitor the delivery of power from a first device to a second device via a first cable, the second device being in data communication with the first device by way of the first cable; circuitry configured to determine that the first device is not delivering power to the second device by way of the first cable; and circuitry configured to, in response to determining, signal a third device to deliver power to the second device by way of a second cable, the third device being in data communication with the second device by way of the second cable; wherein the second device comprises a rechargeable power store; wherein the rechargeable power store of the second device is charged when the first device determines that the first device has surplus power.
