在民航通信中,一般使用E&M接口V类型进行VHF信号的传输。文章就话音信号的传输以及E&M信令的特点,分析了使用E&M信令传输VHF话音信号的原理,并详析了其在Vanguard路由器中的具体实现,猜想E&M板卡失效的原因,并通过实验来论证,最终分析得出其可能原因。
In civil aviation communications, VHF signals are typically transmitted using the E & M interface V type. This paper analyzes the transmission of voice signals and the characteristics of E & M signaling. It analyzes the principle of transmitting VHF voice signals using E & M signaling, analyzes its implementation in Vanguard router, and supposes the reason of E & M board failure. To argue, the final analysis of its possible causes.
