Notification A notification is a prompt that occurs during the daily operation of the NetNumen U31 (RAN) EMS to remind maintenance personnel of system operation status.
A notification indicates the occurrence of a momentary event, but does not indicate potential danger. A notification does not need to be cleared unless it occurs repeatedly.
Usually a notification is a system prompt, and does not affect services. However, under some certain circumstances, a notification will affect services.
