`ABSTRACT
`
`In accordance with the teachings of the present invention, a
`communication system (17) is provided for generating and
`monitoring data over pre-existing conductors (2A-2D)
`between associated pieces of networked computer equipment
`(3A-3D). The system includes a communication device (16)
`attached to the electronic equipment that transmits informa
`tion to a central module (15) by impressing a low frequency
`signal on the pre-existing data lines of the remotely located
`equipment. A receiver (6) in the central module (15) monitors
`the low frequency data on the data lines to determine the
`transmitted information of the electronic equipment. The
`communication device may also be powered by a low current
`power signal from the central module (15). The power signal
`to the communication device may also be ?uctuated to pro
`vide useful information, such as status information, to the
`communication device. Relocation of the electronic equip
`ment with attached communication device to another location
`on the network is detected immediately and may be used to
`update a database. This invention is particularly adapted to be
`used with an existing Ethernet communications link or
`equivalents thereof.
