Abstract
A system for providing power to telephone handsets and other appliances that are connected to a LAN switch. Telephone handsets with built-in Ethernet interfaces can be used to create an enterprise voice communications network which emulates the functions of a standard voice private branch exchange (PBX) switch. The disclosed LAN switch advantageously provides power directly to LAN telephone instruments within the system. The disclosed system may include a means for adding a power system to an existing LAN switch so that remote telephone handsets can receive power from a central location. Alternatively, power equipment may be integrated into a LAN switch itself. The primary benefit of a central power system for Ethernet appliances is that is more convenient to provide back-up power, so that the attached appliances can continue to operate in the event of a power failure. The present system has significant benefits over the most popular current approach, which requires a backup power supply at each telephone instrument or other LAN appliance.
