RBAR Administrative State and Operational Status

The RBAR Administrative State (Admin State) indicates the state the operator wants the RBAR application to be in, and can be manually enabled or disabled. The Operational Status indicates the actual status of the RBAR application. The RBAR Admin State and Operational Status is updated when the application is started or restarted and when RBAR congestion is detected.

Next Generation Network Priority Service (NGN-PS) allows National Security/Emergency Preparedness (NS/EP) users to make priority calls/sessions using public networks. The NGN-PS requests are never discarded due to congestion. NGN-PS messages are always processed by RBAR application except when application is unavailable, in that case configured Exception Action is used for further Routing. For a detailed description of NGN-PS, refer to the Diameter User's Guide and Help.

Table 5-1 describes the Admin State, Operational Status, Operational Reason, and Congestion Levels on the Diameter > Maintenance > Applications page.
