Abstract

An aerospace communication system comprises a communication management unit; a first communication device configured to transmit and receive data over a first communication network; and a second communication device configured to transmit and receive data over a second communication network. The first communication device is coupled to a corresponding interface of the communication management unit. The second communication device is communicatively separated from the communication management unit by the first communication device such that the communication management unit is unaware of the second communication device. The first communication device includes routing logic configured to determine whether to send each message received from the communication management unit over the first communication network or to the second communication device for transmission over the second communication network.
