Centralized alarm signaling
...................................................................................................................................................................................................................................
Introduction
The NE will drive its MDOs according to alarm information it has centralized from
local and remote NEs. A CIT locally connected is used to subscribe or unsubscribe to
alarm status reports from remote NEs. However, the NE is able to drive its MDO
whether a CIT is locally connected or not.
The MDOs behavior in this mode:
• MDO-2 is active when one or more centralized alarms (including possible MDI
alarms) with severity PROMPT are raised
• MDO-3 is active when one or more centralized alarms (including possible MDI
alarms) with severity DEFERRED are raised
• MDO-4 is active when one or more centralized alarms (including possible MDI
alarms) with severity INFO are raised.
Example
This mode is fine for the following application:
