An inter-equipment data link system performs a data link between double equipments of an A data transmission equipment and a B data transmission equipment. In the system, a monitor output of the A data transmission equipment is supplied to the B data transmission equipment. The monitor output of the B data transmission equipment is also supplied to the A data transmission equipment. The monitor output of each of the A, B data transmission equipments includes a data frame according to a High Level Data Link Control procedure. Each of the A, B data transmission equipments includes a monitor data input decomposing unit which receives the data frames of the monitor output supplied by the other, extracts a data frame of an information type therefrom, and obtains a data portion included in an information portion in the extracted data frame as a result of decomposition.
