Abstract
A protected midspan power sourcing equipment for a local area network communications system includes a network connection subsystem that is connectable to at least one first network cable having a plurality of electrical wires, and a powered equipment connection subsystem that is connectable to at least one second network cable also having a plurality of electrical wires. The at least one second network cable is commumncatable with a powered end station of the LAN communications system and provides power signals and voice and data signals to the powered end station. A power source is connected to the second network cable and the powered equipment connection subsystem and generates the power signal that is provided on the at least one second network cable to the powered end station. Electrical surge protectors in the midspan power sourcing equipment are connected to the powered equipment connection subsystem and the at least one second network cable and provide electrical surge protection for the powered end station.
