    • A signal distribution and control system where signals are distributed and control signals transmitted via a single coaxial cable. Integrated Receiver/Decoder (IRD) units communicate with a Frequency Translation Module (FTM) for construction of a custom data signal for delivery to all IRDs coupled to a given FTM. The commands sent by the IRDs to control the FTM inform the FTM which signals are of interest and should be placed on the custom data signal, also called the combined IRD channels. Previously installed IRDs that cannot generate the new commands are still supported in the system via legacy ports in the multiswitch.
    • 信号分配和控制系统,信号分配和控制信号通过单个同轴电缆传输。 集成接收器/解码器(IRD)单元与频率转换模块(FTM)进行通信,用于构建定制数据信号,以传送到耦合到给定FTM的所有IRD。 IRD发送的用于控制FTM的命令通知FTM哪些信号是感兴趣的,并且应该被放置在自定义数据信号上,也称为组合的IRD通道。 以前安装的无法生成新命令的IRD仍然通过多交换机中的旧端口支持系统。
