High Reliability

The USN9810 is highly reliable
because of the following features:


  • Hardware redundancy design


    All critical boards are configured
    in 1+1 or N+1 backup to ensure high reliability of the system.


  • System overload control


    In case of center processing
    unit (CPU) overload or resource congestion, the USN9810 adjusts the
    traffic smoothly to avoid system down.


  • Fault Avoidance


    The USN9810 provides protection mechanisms
    to avoid the following system faults:


    • System power off
    • Maloperation on system power switch
    • Lightning surge on the system power High voltage and low voltage
    • Short circuit of power supply
    • Lightning surge on E1/T1 links
    • Current surge and high voltage on the power supply and interfaces

  • Backup of important data


    The USN9810 automatically backs
    up important data, such as the configuration data, performance data,
    and operation logs.


  • Operation security management


    Different management privileges
    are assigned to different users. During the user login, the USN9810
    checks the user identity. After user login, the USN9810 maintains
    the complete operation to ensure system security.


  • CG redirection and bill buffering


    When the active charging
    gateway (CG) or the link to the active CG fails, the USN9810 sends
    the bills to the standby CG. If the standby CG is also faulty, the
    USN9810 stores the bills in its buffer.
