TheIDU transmits payload data to the ODU on a 280 MHz carrier and receives the ODU data on a 140 MHzcarrier. The IF connection also provides a full-duplex control and monitoring channel between the IDU andODU on a 4.5 MHz carrier. Additionally, this interface provides DC power to the ODU, taken directlyfrom the voltage supplied to the power connection on the rear of the IDU. The power supply is protectedfrom a short-circuit on the IDU/ODU connection via a thermal protection device.5.
