Abstract: This disclosure describes an embodiment of an invention that is sending an information and/or control data signal on a differential signal pair. This embodiment of the apparatus 200 includes an information and/or control data signal 220; a balanced differential signal pair of conductors 212 that includes a positive 202 and a negative 204 differential conductor; a first network of circuits 214 that transforms the information signal 220 into a common mode voltage on the individual conductors 202 and 204 of the balanced differential signal pair of conductors; and a second network of circuits 216 that transforms the common mode voltage on the individual conductors 202 and 204 of the balanced differential signal pair of conductors 212 back to the data signal 222; where the first network of circuits 214 couples to the second network of circuits 216 via the balanced differential signal pair of conductors 202 and 204.

Abstract: The present disclosure describes a system 400 for transmitting power to a remote Power over Ethernet (PoE) subsystem by forwarding Powered Device (PD) input voltage where the subsystem includes a PD and a Power Sourcing Equipment (PSE) device. Included is a master PSE device 402, a first subsystem 410, and a second subsystem 428. The first subsystem 410 includes a first PD 418 that includes a first power switching device 426 and a first PSE device 424. The first power switching device 426 forwards the input power from the first PD 418 to the first PSE 424 without disturbing the PoE handshaking between the devices. The first power switching device 426 uses a switching device with level detection that detects the required input voltage. The second subsystem 428 receives the power from the first subsystem's 410 first PSE device 424. And the second subsystem 428 operates in a manner similar to the first subsystem 410.
