Structuring and controlling the conference system Large conference system with redundant ring topology The redundant ring topology ensures that, should one conference unit or system cable fail or be manipulated, all other conference units of the cable ring will continue to function reliably. For setting up a large conference system with redundant ring topology, you require one ADN CU1 central unit for controlling the conference and additional ADN PS power supplies for powering the conference units. The conference units are interconnected in rings and two rings can be connected to each ADN PS power supply.
