摘要： PURPOSE: A method for testing system paths using a vocoder having bit patterns is provided to easily decide whether each system path of a control station is normal through a monitor by adding a programmable algorithm without changing a hardware, and by generating regular bits in the vocoder of the control station to examine errors of the system paths in the vocoder. CONSTITUTION: A method for testing a vocoder and system paths using bit patterns comprises the steps of: making a control station monitor set up an idle vocoder; making the control station monitor command a system loop back test to the vocoder through a central processing unit(CPU), or command a signal loop back process in a designated point for testing the paths; making the vocoder generate regular bit patterns in a serial interface part, and making signals of the bit patterns pass through an encoding path of the vocoder; making the bit patterns return from a determined specific position, and pass through a decoding path of the vocoder; detecting whether errors are generated on the basis a bit-by-bit result between signals of the returned bit patterns and the bit pattern signals; and displaying a looped-back path on the control station monitor, and displaying a result reported in the vocoder.
摘要翻译：目的：提供一种使用具有位模式的声码器测试系统路径的方法，以便通过在不改变硬件的情况下添加可编程算法以及通过在声码器中生成规则位来容易地判断控制站的每个系统路径是否正常通过监视器以检查声码器中的系统路径的错误。构成：使用位模式测试声码器和系统路径的方法包括以下步骤：使控制站监视器建立空闲声码器; 使控制站监视命令通过中央处理单元（CPU）向声码器进行系统回送测试，或者在指定点指令进行信号回路处理，以测试路径; 使得声码器在串行接口部分中产生规则位模式，并使位模式的信号通过声码器的编码路径; 使位模式从确定的特定位置返回，并且通过声码器的解码路径; 检测是否基于所返回的位模式的信号与位模式信号之间的逐位结果基于产生错误; 并且在所述控制站监视器上显示回环路径，以及显示在所述声码器中报告的结果。
