PROBLEM TO BE SOLVED: To efficiently enable a setting change work when a terminal device for use for a telephone switching device is changed. SOLUTION: In a connection control method by a matrix switch module between the telephone switching device and each terminal device, the matrix module comprises: a plurality of first communication ports connected to each mounted port of the telephone switching device; a plurality of second connection ports connected to the plurality of terminal devices; a matrix switch for connecting the plurality of first connection ports to the plurality of second connection ports; and a matrix switch manager for controlling the matrix switch. By the detection of a connection change of one terminal device, connected to the second connection port, from the second connection port to a different second connection port, it is controlled to connect the one terminal device to a mounting port of an identical identification number in the telephone switching device, even when the installation location of the one terminal device is changed.
