 The transmission unit sends signaling data to the operation & maintenance unit for processing.
                  220V
 The voice data are then sent to baseband processor for processing of rate conversion,
  encryption and interleaving.                                Heat exchanger
 Data are then sent to RF unit for modulation to high-frequency signals.
 Finally, data are then transmitted through the antenna feeder processor.

  the RF unit to 220V into digital signals.
                 convert
 The signals are then transmitted to baseband processor for rate signals conversion, decryption
  and de-interleaving.                                       Heat exchanger
 After conversion to the code pattern, suitable for long-distance transmission, the signals are
  sent to the BSC through the Abis interface.
