FIELD: radio engineering, communication.SUBSTANCE: in the transmission device, a plurality of elements virtually make up one device. Each element comprises at least one main signal transmitting module and a monitoring-control unit connected to the main signal transmitting unit through an internal bus 40 of the device and connected to another monitoring-control unit through a bus between the devices. The monitoring-control unit in one element, in case of breakdown in the controlled main signal transmitting unit, receives a breakdown signal from the controlled main signal transmitting unit and transmits through the bus between devices a control signal for masking the breakdown signal with the monitoring-control unit of another element, having a main signal transmitting unit of the masking recipient. Upon receiving the breakdown signal masking control signal, the main signal transmitting unit of the masking recipient suppresses a secondary breakdown signal upon detecting secondary breakdown.EFFECT: high capacity of the transmission channel.12 cl, 2 dwg |
