ALARMSThe alarms are usually failures that occur during the running of the switching system.They usually lasts for certain period of time and does not recover until the failure disappears. The operators can inquire according to the actual conditions.

After the alarm system is installed, the configuration of the alarm office should be conducted after that. This configuration program requires input of the Area code,Office number, The modules in the office, The number of each module,The rack number .The results of office configuration are saved in the database of the server.

The new configuration is valid only after the program in the alarm server is restarted.

When a place node is selected, the information to be inquired is that of all modules under this place. When a module node is selected, the information to be inquired is that of this module.

CURRENT ALARM INQUIRY

The vertical coordinates of the table indicates CPU occupation rate (%), the value ranging from 0 ~100. There are three valve values.

The horizontal coordinates of the table indicates resource occupation (%), the value ranging between 0~100. There are three valve values.

Both CPU occupation rate and resource occupation rate are divided into four sections. These two values combined to form five levels of call limitation: 0, 1, 2, 3, and 4(refer to call restriction table).
