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

A wireless conference phone system has a base station to couple at least one conference unit to a telephone network, such as the public switched telephone network (PSTN) or a digital telephone network such as a voice over internet protocol (VoIP) network. Each conference unit performs echo cancellation of the audio signal received from a remote location allowing a simplified base station implementation.
