Abstract
The present document describes a method for analyzing the performance of a leg of a cable communication network which uses a network power supply as the power source therefor, the method using a switched-mode power supply device and comprising: electrically connecting an AC output of the switched-mode power supply device to an auxiliary power input of a cable network access device thereby providing an electrical connection to the leg of the cable communication network; switching the power source from the network power supply to the switched-mode power supply thereby providing an AC voltage to the leg of the cable communication network by the switched-mode power supply; performing a diagnosis of the performance of the leg of a cable communication network by controlling a characteristic of the AC voltage being provided to the leg of the cable communication network by the switched-mode power supply.
