Default alarm indication preventions in the system

1 Default alarm indication preventions in the systemAlarm indication preventions for certain alarms have been set by default in RNC. This has been done to reduce the amount of alarm indications that RNC reports to NetAct. The list of alarms below shows the affected alarms that are indication-prevented by default in RNC.

The alarms 7775 and 7795 are indication prevented in RNC because alarm 3325 informs about WCEL parameter inconsistencies in RNC level. For more information, see the instructions given for alarms 7775, 7795, and 3325. Alarm 7799 is an old test alarm for RNC testing purposes which is not set by RNC in any situation anymore.

28 7650 BASE STATION FAULTYMeaning

A critical fault (or faults) has occurred in the base station.

Check the reason for the fault from the supplementary text field ofthe alarm.

The effect of the fault on the functioning of the network elementdepends on the fault description. For more information, see basestation fault descriptions in WCDMA RAN and I-HSPA System Libraries.

Supplementary information fields1 rack (cabinet) number

2 shelf number

3 slot

4 type of unit

5 unit number

6 subunit number

For more information, see instructions on Alarm Structure.

InstructionsVerify the configuration of a BTS by checking the commissioning, cablingand correct installation of the units/modules at the BTS. Make sure theenvironment does not cause the fault.

Before a unit/module is replaced at the BTS, the site should be reset torecover from any temporary faults which might have caused themalfunctioning of the unit/module. When an active alarm is a 'Start'alarm, a site reset is required to cancel the alarm. If the site reset ormodule block/unblock does not help, replace the faulty unit/module (seethe source of the alarm and instructions fields of the correspondingalarms).

Below is the list of BTS fault(s) which might have caused this alarm inBTS WN6.0_EP1 release. In case of earlier SW release and in case you needmore detailed fault descriptions refer to WCDMA RAN and I-HSPA SystemLibraries. The BTS fault descriptions are also included in BTS SW releasedocumentation. If that does not help, contact your local Nokia SiemensNetworks representative.

The effect of the fault on the functioning of the network elementdepends on the fault description. For more information, see basestation fault descriptions in WCDMA RAN and I-HSPA System Libraries.

Supplementary information fields1 rack (cabinet) number

2 shelf number

3 slot

4 type of unit

5 unit number

6 subunit number

For more information, see instructions on Alarm Structure.

InstructionsVerify the configuration of a BTS by checking the commissioning, cablingand correct installation of the units/modules at the BTS. Make sure theenvironment does not cause the fault.

Before a unit/module is replaced at the BTS, the site should be reset torecover from any temporary faults which might have caused themalfunctioning of the unit/module. When an active alarm is a 'Start'alarm, a site reset is required to cancel the alarm. If the site reset ormodule block/unblock does not help, replace the faulty unit/module (seesource of the alarm and instructions fields of the corresponding alarms).

Below is the list of BTS fault(s) which might have caused this alarm inWN6.0_EP1 release. In case of earlier SW release and in case you need moredetailed fault descriptions refer to WCDMA RAN and I-HSPA System Libraries.The BTS fault descriptions are also included in BTS SW releasedocumentation. If that does not help, contact your local Nokia SiemensNetworks representative.

FAULT NAME : autonomous reset as recovery action

7652 BASE STATION NOTIFICATION

MEANING : The BTS tries to correct a fault situation by performing a recovery reset to a unit, the site or the BTS.INSTRUCTIONS : Check the alarm history and other active alarms of the unit.

Note! This alarm does not require any (special) actions.

FAULT NAME : 2M external reference missingMEANING : The reference clock monitoring has detected a loss of 2.048MHz signal received from an external reference source, connected to Sync In interface of the System Module.INSTRUCTIONS : Note! Perform the steps below in the listed order until the alarm disappears.

1. Check the cabling (connected to Sync In interface).

2. Check that the 2.048MHz reference source is working normally and the 2.048MHz signal is available.

3. Replace the alarming module.

FAULT NAME : ATM cell lossMEANING : ATM cells are lost. The cell loss can be caused by a traffic overload, by the WAM receiving an invalid ATM cell or AAL5 packet, or by the data corruption on the Iub (that is, a bad BER).

The most common causes for this fault are transmission network problems (causing unnecessary WAM changes).INSTRUCTIONS : 1. Check that bandwidths (cells/s) are the same at the BTS, AXC and RNC.

2. Check the data integrity from the incoming Iub (see Troubleshooting instructions).

3. Check the other transmission elements' active faults (see the Faults for AXC document).

4. Check the WAM, AXU and the cabling between them.

FAULT NAME : ATM, A2EA configuration errorMEANING : The RNC A2EA transport layer address does not comply with the given BTS A2EA address.

This fault is reported to the BTS Site Manager only.INSTRUCTIONS : Check and re-commission the AXC (if AAL2 multiplexing is in use), RNC or BTS with the correct BTS A2EA addresses.

FAULT NAME : Active clock tuning faultMEANING : The phase measurement cannot be performed in the active WSC or WMC.INSTRUCTIONS : 1. Run fast tuning with BTS Site Manager.
