A device that is part of, and is addressable in, a local area network in a building for coupling a digital data signal to a data unit, the network including at least part of an existing telephone wire pair terminated by an outlet, the wire pair carrying a frequency multiplexed analog service signal and a digital data signal. The device includes: a telephone connector for connecting the device to the telephone wire pair; a filter coupled to the telephone connector to pass only the digital data signal; a modem coupled for bi-directional digital data signal communication with additional modems over the telephone wire pair; a data connector for connecting to the data unit; a data transceiver coupled to effect full-duplex serial digital data communication with the data unit; a power port; and a single enclosure housing the filter, the power supply, the modem and the data connector.
