A data terminal is inductively coupled to a telephone line without the need to make any physical connection to the line. In one embodiment, the invention comprises a slim unit containing a pair of flat coils which fits between the jack and plug of a jack-ended telephone. The prongs of the jack pass through the central aperture of the coils, thereby inductively coupling the line to the coils. The coils, in turn, are connected to the modem associated with the data terminal.
