Impact on the System

  • When this alarm is generated, the TRX directly runs the download software if the memory (download Flash or ROM) of the TRX has available download software.
  • Thus, the version of the running download software is inconsistent with the expected version. The version number of the running download software is obtained from only the BTS log of the related TRX. The version queried from the maintenance console is invalid.
