    • D.

      Prueba de envio de AGC

    Correct Answer
    A. Prueba de la etapa de recepcion de RF
    Explanation
    The given correct answer is "Prueba de la etapa de recepcion de RF" which translates to "Test of the RF reception stage". This is the most appropriate answer because the initial statement mentions "verificar el desempeño del AGC" which means "to verify the performance of the AGC". The AGC (Automatic Gain Control) is a feature commonly used in the RF reception stage to adjust the signal strength and maintain a consistent level. Therefore, testing the RF reception stage would involve checking the performance of the AGC.

    • D.

      MI-REI y MI-RDA

    Correct Answer
    A. MS-REI y MS-RDI
    Explanation
    The correct answer is MS-REI and MS-RDI. These are two types of signals that are generated in the remote end of the SDH system. MS-REI stands for Multiplex Section Remote Error Indication, which is a signal that indicates errors in the multiplex section of the SDH system. MS-RDI stands for Multiplex Section Remote Defect Indication, which is a signal that indicates defects in the multiplex section of the SDH system. These signals are important for monitoring and troubleshooting the SDH system.

      Fuinciones Recepcion

    Correct Answer
    B. Finciones de Adaptacion
    Explanation
    The correct answer is "Finciones de Adaptacion." This is because the given statement mentions that these functions are related to the adaptation or conversion of signals during different stages of the process. "Finciones de Adaptacion" translates to "Adaptation Functions" in English, which aligns with the explanation provided in the statement. These functions are responsible for adjusting or converting signals to ensure compatibility and smooth transmission between different stages of the process.

    Correct Answer
    C. RS-TIM
    Explanation
    The correct answer is RS-TIM. RS-TIM refers to the Remote Supervision-Tandem Interface Module, which is responsible for monitoring and controlling the transmission of data between the transmitting and receiving parts. It is used to ensure that the data is correctly transmitted and received by comparing the identification of the path contained in the J0 byte.
