The present disclosure describes a systemfor 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, a first subsystem, and a second subsystem. The first subsystemincludes a first PDthat includes a first power switching deviceand a first PSE device. The first power switching deviceforwards the input power from the first PDto the first PSEwithout disturbing the PoE handshaking between the devices. The first power switching deviceuses a switching device with level detection that detects the required input voltage. The second subsystemreceives the power from the first subsystem'sfirst PSE device. And the second subsystemoperates in a manner similar to the first subsystem

This disclosure describes a bridge and control proxy for unified communication systems. The bridge transmits and receives data from a unified communication system. In addition, the bridge transmits and receives data from a non-compatible device. The bridge translates the data between the unified communication system and the non-compatible device. The bridge stores selected data such as presence information for later use by the unified communication system and/or the non-compatible device. Further, the bridge uses Web services to discover, promote, and/or advertise non-compatible devices to the unified communication system.
