11.8 ALFOPLUS ALARMS
Alarms are divided in groups depending on functionality or hardware module that has the failure or the
problem described by the alarm itself.
In the following pages are described:
most common scenarios with the problem that has generated them
all the alarm groups with:
- name (number of radio branch can vary depending on configuration)
-severity
- explanation of the alarm
- most common solution of the problem described by the alarm
Eventual concatenations of alarms of that group:
- alarms that cause an alarm in the selected group (parent)
- alarms generated by alarms of that selected group (son)
Quality problems: what is the cause... rain or interferences? An easy example of troubleshooting
using Performance monitoring.
