  • System and method for controlling a multi-point matrix switch
    Patent number: 5179550
    Abstract: A system and method for controlling a multi-point matrix switch (13) to route signals in a communication system (11). The invention identifies source and destination ports (129, 133) in the communication system (11) and then polls identified ports (129, 133) to recognize those that are available for communication. Identified and recognized ports (129, 133) are displayed graphically, so that at least one path (139) between recognized source ports (129, 133) and associated recognized destination ports (129, 133) may be selected graphically by user (159) input. Selected path (139) information is then submitted to switch (13) to cause switch (13) to route signals through the selected paths (139) by connecting recognized source ports (129, 133) to associated recognized destination ports (129, 133).
