    • A satellite communications interoperability module and method for frequency down-conversion. The module insertable in-line with an intra-facility link communicating a multiplexed signal between the outdoor unit (ODU) and the indoor unit (IDU). Electrical circuitry of the module transforming and forwarding the multiplexed signal over the intra-facility link, the multiplexed signal including at least direct current, a standard tone, and L-band data signals. Switching means of the module specifies operations performed by the electrical circuitry to transform the multiplexed signal frequencies, waveforms and voltages according to predetermined parameters compatible between the ODU and the IDU. An interoperability method for compatibility with a range of different indoor units applied by the interoperability module and or incorporated into an integral ODU is application of a second frequency shift upon the L-band signal output from the ODU primary down-conversion circuit.
    • 一种用于降频转换的卫星通信互操作模块和方法。 该模块与室外单元(ODU)和室内单元(IDU)之间传送多路复用信号的工厂内链路成对插入。 模块的电路通过工厂内链路转换和转发多路复用信号,多路复用信号至少包括直流电,标准音调和L波段数据信号。 模块的切换装置指定由电路执行的操作,以根据与ODU和IDU之间兼容的预定参数来变换复用的信号频率,波形和电压。 与由互操作性模块应用或并入整体ODU的不同室内单元的一系列兼容性的互操作性方法是在从ODU主下变频电路输出的L波段信号上施加第二频移。
