ABSTRACT:
A controlled access automated-switching conferencing system includes a special microprocessor-controlled control console disposed at each of a plurality of stations. Each station includes video and audio inputs and outputs. Central automatic video and audio switching devices switch the video and audio inputs so that they may be connected to any one or more of the video and audio outputs, and switch the audio outputs so that they may be connected to one or more audio inputs. A central novel system controller controls the automatic switchers in response to selections of function and station selection members associated with any of the control consoles. An interface is associated with each station for operatively interconnecting the station control console, inputs, and outputs with the system controller, and a central line driver interfaces the system controller with the interface structure. The control console function select members have hold, call, cancel, and alternate video functions and a test function for the microprocessor.
