Abstract
Various methods, apparatuses, and systems in which fault monitoring is provided to a network interface device are described. In one embodiment, an apparatus includes a network interface device (NID) located outside a building and a power supply unit located inside the building. The power supply unit has one or more ports that couple via a phone line to the NID to provide a power signal to the NID. The apparatus further includes a monitor circuitry located in the power supply unit. The monitor circuitry monitors the power signal received by the NID via the phone line. The monitor circuitry checks for a fault condition of at least one phone device coupled to the phone line when the power signal changes by a predetermined amount.
