Troubleshooting faults using alarm description tables
1. Check the alarm number and alarm name and find its alarm description
table in Chapter 3 in this document.
2. Find the fault reason in the Fault reason field in the alarm description table.
3. Follow the instructions given in the Instruction field. See also the alarm
cancelling information in the Cancelling field.
4. If the fault reason cannot be found in the Fault reason field, follow the
instructions given for Other faults.
Instructions given for Other faults apply to several different fault reasons.
2.3 Fault reporting
Where possible, correct all damage, failures, and faults and report them to Nokia
using the Failure Report Form provided by Nokia Customer Services.
You can save the alarm information to a log file on your PC with Nokia MetroSite
BTS Manager.
2.4 Alarm reclassification
In fault situations, Nokia MetroSite EDGE Base Station runs an automatic
reclassification procedure for major (**) and critical (***) alarms before it sends
an alarm to the BSC. When an object becomes faulty, only one critical (***)
alarm from the object can be active at a time.
In reclassification, the alarm handling detects which logical base station object is
affected by a unit level fault. After reclassification, an object level alarm is issued
according to a certain hierarchy, as described in Figure 4.
