For more information, see instructions on Alarm Structure. Instructions Verify the configuration of a BTS by checking the commissioning, cabling and correct installation of the units/modules at the BTS. Make sure the environment does not cause the fault. Before a unit/module is replaced at the BTS, the site should be reset to recover from any temporary faults which might have caused the malfunctioning 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 or module block/unblock does not help, replace the faulty unit/module (see the source of the alarm and instructions fields of the corresponding alarms). Below is the list of BTS fault(s) which might have caused this alarm in BTS WN 8.0 release. In case of earlier SW release and in case you need more detailed fault descriptions refer to WCDMA RAN and Flexi Direct System Libraries. The BTS fault descriptions are also included in BTS SW release documentation. If that does not help,

: BTS reference clock missing : 3080: EFaultId_BtsReferenceClockMissing : This BTS fault indication is generated if the reference clock monitoring function of the BTS does not receive the highest configured synchronization reference signal or if all the synchronization reference signals are missing. The BTS fault is not generated if the highest configured synchronization source is present, no matter what the lower level source statuses are. Background information: There is a fixed synchronization priority list in the FlexiBTS: -Priority 1: PPS (Pulse Per Second) signal connected to the Synchronization Input interface (Sync In) of the System Module. Normally the PPS signal is generated by the GPS receiver. -Priority 2: external 2.048MHz signal connected to the Sync

In interface. -Priority 3: the reference signal coming from the integrated transmission unit (FTM). Normally, all the FlexiBTS sources are not in use at the same time (it depends on the network planning and BTS configuration). During the BTS start-up, the available sources are checked against the reference source list in the BTS commissioning file and deviations regarding the missing highest priority source generate a fault. During runtime operation, the BTS fault functionality runs autonomously - notices also added/vanished sources which are missing from the commissioning file. The source for the FTM (which is the priority 3 source for the FlexiBTS) can be TDM interface signal (for example E1, T1...), physical layer Synchronous Ethernet (SyncE) signal or application layer Timing over Packet (ToP) in which the timing information to BTS(s) is generated by a ToP master. The FTM reference source priority selection is not fixed but user-selectable. Furthermore, if a signal listed in the FTM references is not received, a BASE STATION TRANSMISSION ALARM is reported. INSTRUCTIONS: Depending on the installed and commissioned synchronization source(s) listed in section "Meaning", see the commissioned synchronization option below and perform the steps in the listed order until the BTS fault indication disappears. GPS receiver (PPS source): 1. If there is a GPS receiver commissioned at the BTS site, note the following: If the GPS receiver is not locked to any satellite, it turns off the PPS signal which is normally delivered to the BTS (Sync In interface). The most common reason is that the GPS receiver does not see any satellites because of poor antenna installation (poor sky visibility). The only permanent cure for this is to change the GPS antenna location. One indication of a fairly poor sky visibility is that the BTS fault is activated/canceled every now and then. 2. There might be a malfunction in the GPS receiver. Perform a (remote) power reset for the GPS receiver. 3. There might be a malfunction in the BTS. Perform a BTS site reset. 4. The GPS cable and/or connectors might be damaged. Check the cable and the connectors. 5. There might be a HW fault in the GPS receiver. Check the operation and change the HW, if needed. External 2.048MHz signal: 1. If there is an external 2.048MHz signal source commissioned at the BTS site, check the BTS faults of that device and act accordingly. If this does not help, check the cables. Note that since the device type is not known, detailed instructions cannot be given. For further actions refer to the appropriate user manual of the device.

2. There might be a malfunction in the BTS. Perform a BTS site reset. FTM reference (TDM, SyncE or ToP as source): 1. If there is an integrated transmission unit (FTM) commissioned at the BTS site, note the following: the FTM unit operates so that if it is not locked to a synchronization source, it turns off the clock reference signal which is normally delivered to the BTS master clock. The synchronization source of the FTM (set by the FTM synchronization priority setting) might be missing, causing the FTM internal clock to drop to holdover mode. In this case, the fault in the transmission network must be corrected (FTM itself might be working fine). 2. Check the alarms of the FTM unit and act accordingly. 3. Check the synchronization settings of the FTM unit. 4. There might be a malfunction in the BTS. Perform a BTS site reset. 5. There might be an equipment failure in the FTM unit. Check the operation and replace the unit, if needed. Note: Normally the reason is not an equipment failure, but there might be connection failures in the transmission or packet network, causing the FTM clock to drop to holdover mode. Especially the BTS fault indication activity (frequent BTS fault indication activations/cancels instead of a stable BTS fault indication state) points to the transmission network instability, not to a failure in the unit. If the previous steps do not help, there might be an equipment failure in the System Module. Check the operation and if resetting the BTS site does not help, replace the System Module.

The alarm is activated if the WMC tunes the oven oscillator so that the DAC word (parameter to control the oven oscillator output frequency) value becomes lower than 205 or greater than 3891 (5 of the total adjustment area). The range for the DAC word is 0 - 4095. The cause of the alarm can be: - The Iub reference frequency has been incorrect for a long time (up to several days) due to a fault in the transmission network synchronisation (which in turn is caused by an equipment fault or a setting error). Before activating this alarm, the alarm 7652 BASE STATION NOTIFICATION: 'Difference between BTS master clock and reference frequency' may have been active. - If the BTS integrated transport part receives the synchronisation information via the 2.048 MHz synchronisation input (external clock source), the alarm situation may be caused by a fault in that signal. In that case the alarm behaviour notifications listed with the Iub signal (see above) are also valid in this case. - The fast tuning action of the BTS master clock may have been executed without checking if the reference signal is correct or not. If the reference signal is incorrect during the fast tuning execution, it may result in adjusting the BTS master clock frequency far from the nominal value, which causes serious problems in the network performance. - There is an equipment fault in the BTS. - Due to the oven oscillator (OCXO) aging inside the WSC unit, the unit may be approaching the end of its lifetime. In such case, after the alarm activation, the DAC value is quite stable, whereas in the other fault cases it may be very unstable or at the edge of the adjustment area (0 or 4095).

INSTRUCTIONS: 1. In case of a fault in the transmission network synchronisation, the network synchronisation must be corrected. The long-term accuracy of the Iub signal must be 0.015 ppm or better. 2. In case of a BTS equipment fault, the location may be: a.

the fast tuning procedure with the BTS Site Manager. - If there is no cure in a few minutes, reset the site. - If that does not help, replace the WMC unit. 3. After the fault situation has been cleared, the BTS master clock may also require tuning, because the BTS master clock adjustment is quite slow. The tuning may be done: - Manually, by changing the DAC word (during a site visit). - Or with fast tuning, by which the BTS master clock is tuned in a few minutes automatically near the Iub reference (normal tuning takes care of the fine tuning). Note, however, that the fast tuning should only be used in case the Iub reference signal is known to be a good one. Otherwise the BTS frequency may be tuned into a totally incorrect value, causing serious problems in the network performance. Background information: The principle is that in a mobile network, the synchronisation goes from MSC => RNC => BTS. But in reality that chain might be broken somewhere and, for example, when using leased lines, the BTS may take the reference synchronisation from the transmission network of another operator. This does not harm the system if also the synchronisation of the leased line service provider is accurate/stable enough. The BTS uses the incoming synchronisation signal as a reference for the Air interface, the accuracy requirement of which is set by 3GPP.

For more information, see instructions on Alarm Structure. Instructions Verify the configuration of a BTS by checking the commissioning, cabling and correct installation of the units/modules at the BTS. Make sure the environment does not cause the fault. Before a unit/module is replaced at the BTS, the site should be reset to recover from any temporary faults which might have caused the malfunctioning 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 or module block/unblock does not help, replace the faulty unit/module (see source of the alarm and instructions fields of the corresponding alarms). Below is the list of BTS fault(s) which might have caused this alarm in WN 8.0 release. In case of earlier SW release and in case you need more detailed fault descriptions refer to WCDMA RAN and Flexi Direct System Libraries.

-Priority 1: PPS (Pulse Per Second) signal connected to the Synchronization Input interface (Sync In) of the System Module. Normally the PPS signal is generated by the GPS receiver. -Priority 2: external 2.048MHz signal connected to the Sync In interface. -Priority 3: the reference signal coming from the integrated transmission unit (FTM). Normally, all the FlexiBTS sources are not in use at the same time (it depends on the network planning and BTS configuration). During the BTS start-up, the available sources are checked against the reference source list in the BTS commissioning file and deviations regarding the missing highest priority source generate a fault. During runtime operation, the BTS fault functionality runs autonomously - notices also added/vanished sources which are missing from the commissioning file. The source for the FTM (which is the priority 3 source for the FlexiBTS) can be TDM interface signal (for example E1, T1...), physical layer Synchronous Ethernet (SyncE) signal or application layer Timing over Packet (ToP) in which the timing information to BTS(s) is generated by a ToP master. The FTM reference source priority selection is not fixed but user-selectable. Furthermore, if a signal listed in the FTM references is not received, a BASE STATION TRANSMISSION ALARM is reported. INSTRUCTIONS: Depending on the installed and commissioned synchronization source(s) listed in section "Meaning", see the commissioned synchronization option below and perform the steps in the listed order until the BTS fault indication disappears. GPS receiver (PPS source): 1. If there is a GPS receiver commissioned at the BTS site, note the following: If the GPS receiver is not locked to any satellite, it turns off the PPS signal which is normally delivered to the BTS (Sync In interface). The most common reason is that the GPS receiver does not see any satellites because of poor antenna installation (poor sky visibility). The only permanent cure for this is to change the GPS antenna location. One indication of a fairly poor sky visibility is that the BTS fault is activated/canceled every now and then. 2. There might be a malfunction in the GPS receiver. Perform a (remote) power reset for the GPS receiver. 3. There might be a malfunction in the BTS. Perform a BTS site reset. 4. The GPS cable and/or connectors might be damaged. Check the cable and the connectors. 5. There might be a HW fault in the GPS receiver. Check the operation and change the HW, if needed.

External 2.048MHz signal: 1. If there is an external 2.048MHz signal source commissioned at the BTS site, check the BTS faults of that device and act accordingly. If this does not help, check the cables. Note that since the device type is not known, detailed instructions cannot be given. For further actions refer to the appropriate user manual of the device. 2. There might be a malfunction in the BTS. Perform a BTS site reset. FTM reference (TDM, SyncE or ToP as source): 1. If there is an integrated transmission unit (FTM) commissioned at the BTS site, note the following: the FTM unit operates so that if it is not locked to a synchronization source, it turns off the clock reference signal which is normally delivered to the BTS master clock. The synchronization source of the FTM (set by the FTM synchronization priority setting) might be missing, causing the FTM internal clock to drop to holdover mode. In this case, the fault in the transmission network must be corrected (FTM itself might be working fine). 2. Check the alarms of the FTM unit and act accordingly. 3. Check the synchronization settings of the FTM unit. 4. There might be a malfunction in the BTS. Perform a BTS site reset. 5. There might be an equipment failure in the FTM unit. Check the operation and replace the unit, if needed. Note: Normally the reason is not an equipment failure, but there might be connection failures in the transmission or packet network, causing the FTM clock to drop to holdover mode. Especially the BTS fault indication activity (frequent BTS fault indication activations/cancels instead of a stable BTS fault indication state) points to the transmission network instability, not to a failure in the unit. If the previous steps do not help, there might be an equipment failure in the System Module. Check the operation and if resetting the BTS site does not help, replace the System Module.

: Difference between BTS master clock and reference frequency : 9: EFaultId_DacWordChangeAl : The reference frequency that the BTS master clock receives from the transport part has changed by about 0.2 ppm or more (which equals the change magnitude of 204 DAC steps or more) during the measurement period (about 20 minutes), compared to the BTS master clock frequency. The cause of the alarm can be: 1. The Iub reference frequency has changed due to a fault in the transmission network synchronization (which in turn is caused by an equipment fault or a setting error). Note that if the network synchronization malfunction lasts for a long time, the alarm is canceled when the BTS frequency reaches the faulty Iub synchronization. The alarm can also be activated if the faulty Iub synchronization is corrected and there is again the difference of 0.2 ppm or more. The alarm is canceled whenever the difference becomes smaller than 0.2 ppm. 2. The Iub reference frequency fluctuates continuously due to a great deal of jitter/wander in the transmission network. The alarm is continuously activated/canceled (however, the alarming state may predominate). There is always some jitter/wander in the transmission network; the limits are defined in ITU-T G.823/824/825. 3. If the BTS integrated transport part receives the synchronization information via the 2.048 MHz synchronization input (external clock source), the alarm situation may be caused by a fault of that signal. In that case, the alarm behavior notifications listed with the Iub signal (see above) are also valid in this case. 4. There is an equipment fault in the BTS. The equipment fault is, however, not the most common reason. Normally the reason can be found in the Iub/reference signal behavior (see the descriptions above).

activation, a BTS Clock Frequency History feature has been developed. You can access the stored history data via BTS Site Manager. You can use the history data as a tool for finding out the reason for the fault/alarm situation (for further instructions about the history feature, see the online help of BTS Site Manager). Depending on the possible reason, follow the instructions below: 1. In case of a fault in the transmission network synchronization, you must correct the network synchronization. The long-term accuracy of the Iub signal must be 0.015 ppm or better (check the correct Iub accuracy by measuring it). No actions on the BTS are necessarily needed. 2. If the basic accuracy of the Iub signal is in order but there is too much instability, that is, the jitter/wander is outside the acceptable limits, you must correct the synchronization of the transmission network. The limits for the jitter/wander are defined in the ITU-T G.823/824/825. No actions on the BTS are needed. 3. In case of a BTS equipment fault, the location may be: Transport part: - First check the alarms of the AXC node with AXC Manager, or FTM and act accordingly.
- If there are no alarms, check the AXC/FTM synchronization settings. WSC/FCM unit: - If both the Iub reference signal accuracy and the AXC/FTM are in order but the WSC/FCM unit is still alarming, run the fast tuning with BTS Site Manager. - If the alarm is still active after the fast tuning is finished, reset the site. If the problem does not disappear in a few minutes, reset the site. - If that does not help, replace the WSC/FCM unit. Note that if the reason is in the transmission network synchronization, replacing the faulty unit does not correct the situation. Furthermore, the alarm activity (frequent alarms/cancels) points to an instability in the transmission network, not to a fault in the unit. 4. After the fault situation has been cleared, you might need to tune the BTS master clock because the BTS master clock adjustment is quite slow. You can perform the tuning: - manually by changing the DAC word (during a site visit) - or with fast tuning, in which the BTS master clock is tuned in a few minutes automatically near the Iub reference (normal tuning takes care of the fine tuning). Note, however, that you should only use the fast tuning in case the Iub reference signal is known to be a good one.

Otherwise the BTS frequency may be tuned into a totally incorrect value, causing serious problems in the network performance. Background information: The principle is that in the mobile network, the synchronization goes from MSC => RNC => BTS. But in reality that chain might be broken somewhere and, for example, when using leased lines, the BTS may take the reference synchronization from the transmission network of another operator. This does not harm the system if the synchronization of the leased line service provider is also accurate/stabile enough. The BTS uses the incoming synchronization signal as a reference for the Air interface, the accuracy requirement of which is set by 3GPP.

GPS Receiver alarm: no stored position 4124: EFaultId_GpsReceiverNoStoredPositionAl There is no accurate position stored in EEPROM. Perform the steps below in the listed order until the fault disappears. No stored position: 1. One of the GPS receiver settings is incorrect. Using the manager SW of the GPS receiver, set the receiver to store the position into non-volatile memory. If there is no tick mark in the position storage selection, the GPS receiver runs the site/self survey every time the GPS receiver is reset (either by manager command, power outage, or a GPS recovery reset). This means that if the GPS receiver installation quality is only average - and especially if the installation is a poor one - the GPS receiver turns the PPS reference OFF every now and then during the site survey. This means the BTS master clock drops to holdover mode much easier during the survey than during the normal operation.

See documentation for installations, and if there are discrepancies with the actual installation, re-install the GPS antenna. Note that even when the GPS antenna has a good sky visibility, the problem might be caused by installing the GPS antenna too close to the transmitter antenna(s) of the BTS, causing disturbances to the GPS receiver. 2. There might be a malfunction in the GPS receiver. Perform a (remote) power reset for the GPS receiver. 3. There might be a HW fault in the GPS receiver.

The GPS receiver has valid position data but it is not properly in line with the information estimated from the actual satellite visibility. The reason for this fault indication might be that the GPS antenna installation has not been done properly, that is the sky visibility is not good enough. Please refer the documentation for instructions and if there are deviations with the actual installation, re-install the GPS antenna. Please notice that even when the GPS antenna has a good sky visibility, the problem might be caused by installing the GPS antenna too close to the transmitter antenna(s) of the BTS, causing disturbancies for the GPS receiver. 2. There might be a malfunction in the GPS receiver. Perform a (remote) power reset for the GPS receiver. 3. There might be a HW fault in the GPS receiver.

GPS Receiver alarm: survey in progress 4123: EFaultId_GpsReceiverSurveyInProgressAl The GPS receiver is running a site/self survey. Perform the steps below in the listed order until the fault disappears. Survey in progress: 1. Do nothing. The alarm is informative only. Normally, the GPS receiver runs the survey for two reasons: a) somebody has started the survey manually; b) the GPS receiver has detected that the position has changed and the receiver has started an automatic survey. Note also that an automatic survey takes place every time during the first start-up. 2. If an automatic survey takes place every now and then, it might be an indication that the sky visibility is poor, and based on the poorly tracked satellites, the GPS receiver concludes that the position has changed. In this case, check activity of other faults (BTS fault history data), and if feasible, re-install the GPS antenna. 3. If the GPS installation is good but still an automatic survey takes place every now and then, there might be a malfunction in the GPS receiver. Perform a (remote) power
reset for the GPS receiver. 4. If the actions detailed in previous steps do not correct the situation, there might be an HW fault in the GPS receiver. Check the operation and change the GPS module if needed.

alarm can be: - The Iub reference frequency has been incorrect for a long time (up to several days) due to a fault in the transmission network synchronization (which in turn is caused by an equipment fault or a setting error). Before activating this alarm, the alarm 7652 BASE STATION NOTIFICATION: 'Difference between BTS master clock and reference frequency' may have been active. - If the BTS integrated transport part receives the synchronization information via the 2.048 MHz synchronization input (external clock source), the alarm situation may be caused by a fault in that signal. In that case, the alarm behavior notifications listed with the Iub signal (see above) are also valid in this case. - The fast tuning action of the BTS master clock may have been executed without checking if the reference signal is correct or not. If the reference signal is incorrect during the fast tuning execution, it may result in adjusting the BTS master clock frequency far from the nominal value, which causes serious problems in the network performance. - There is an equipment fault in the BTS. - Due to the oven oscillator (OCXO) aging inside the WSC unit, the unit may be approaching the end of its lifetime. In such case, after the alarm activation, the DAC value is quite stable, whereas in the other fault cases it may be very unstable or at the edge of the adjustment area (0 or 4095). Note that if the alarm 7651 BASE STATION OPERATION DEGRADED: 'WSC oven oscillator fault' becomes active, it may cause the alarm 7652 BASE STATION NOTIFICATION: 'Difference between BTS master clock and reference frequency' to cancel. INSTRUCTIONS: 1. In the case of a fault in the transmission network synchronization, you need to correct the network synchronization. The long-term accuracy of the Iub signal must be +/- 0.015 ppm or better. 2. In case of BTS equipment fault, the location may be: 2.1 Transport part - First check the alarms of the AXC node with AXC Manager and act accordingly. - If there are no alarms, check the AXC synchronization settings. 2.2 WSC unit - If both the Iub reference signal accuracy and the AXC node are in order but the WSC unit is still alarming, run the fast tuning procedure with BTS Site Manager. - If that does not solve the problem in a few minutes, reset the site. - If that does not help, replace the WSC unit.

case the BTS is equipped with two WSCs, the redundant unit takes over the operation of the faulty unit. But if the fault situation is caused by an incorrect reference signal, both the WSC units may start alarming sooner or later. 3. After the fault situation has been cleared, the BTS master clock may also require tuning, because the BTS master clock adjustment is quite slow. You can perform the tuning: - manually, by changing the DAC word (during a site visit), or - with fast tuning, where the BTS master clock is tuned automatically in a few minutes near the Iub reference (normal tuning takes care of the fine tuning) Note, however, that the fast tuning should only be used in case the Iub reference signal is known to be a good one. Otherwise the BTS frequency may be tuned into a totally incorrect value, causing serious problems in the network performance. Background information: The principle is that in a mobile network, the synchronization goes from MSC > RNC > BTS. But in reality that chain might be broken somewhere and, for example, when using leased lines, the BTS may take the reference synchronization from the transmission network of another operator. This does not harm the system if also the synchronization of the leased line service provider is accurate/stable enough. The BTS uses the incoming synchronization signal as a reference for the Air interface, the accuracy requirement of which is set by 3GPP.

INSTRUCTIONS: 1.If the basic accuracy of the Iub signal is in order but there is too much instability, that is, the jitter/wander is outside the acceptable limits, the synchronization of the transmission network must be corrected. The limits for the jitter/wander are defined in the ITU-T G.823. No actions on the BTS are needed. 2. Reset the site and wait about 10 minutes. 3. Try a power-on reset. If the alarm reappears, replace the unit. If the alarm reappears during the next few weeks or the clock seems unstable, replace the unit.

Verify the configuration of a BTS by checking the commissioning, cabling and correct installation of the units/modules at the BTS. Make sure the environment does not cause the fault. Before a unit/module is replaced at the BTS, the site should be reset to recover from any temporary faults which might have caused the malfunctioning 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 or module block/unblock does not help, replace the faulty unit/module (see the source of the alarm and instructions fields of the corresponding alarms). Below is the list of BTS fault(s) which may have caused this alarm in BTS WN 8.0 release. In case of earlier SW release and in case you need more detailed fault descriptions refer to WCDMA RAN and Flexi Direct System Libraries.

Multicontroller RNC, IPA-RNC and Flexi Direct RNC Base Station Alarms (7000-7900)
36 7665 BASE STATION TRANSMISSION ALARM Meaning A transmission fault (or faults) has occurred in the BTS. This alarm is an encapsulation alarm that is used to transfer the Flexi Transport Submodule (FTM) alarm data over the BTS O&M connection through RNC and OMS to NetAct. Encapsulation is used because the RNC alarm system cannot support the FTM alarms directly due to differences in the alarm structure. In NetAct and OMS this alarm is shown in opened format. This means that the alarm number, alarm text and supplementary information are shown in original FTM format and the alarm printout is thus different in NetAct compared to alarm listings in RNC MML interface that shows these FTM alarms as instances of alarm number 7665. Check the reason for the fault from the supplementary information fields and supplementary text field of the alarm. The actual documentation for the encapsulated alarm can be found in the BTS faults documents in WCDMA RAN and Flexi Direct System Libraries. The effect of the fault on the functioning of the network element depends on the fault description.

7750 FAILURE IN WCDMA WBTS O&M CONNECTION
38 7750 FAILURE IN WCDMA WBTS O&M CONNECTION Meaning This alarm indicates that a failure has occurred in WBTS O&M connection. The problem is related to Iub connection between controller and WBTS. From controller point of view the actual reason for the failure is either in transmission network between controller and WBTS, in internal communication of controller applications or in WBTS configuration. This alarm is set by controller in the following situations: 1) WBTS has closed the O&M connection. 2) WBTS O&M connection supervision message has not arrived within expected time 3) there is a problem in transmission network between controller and WBTS 4) a WBTS id conflict has been detected in the network As a consequence of this alarm, the availability of WBTS O&M functionality may be limited. User initiated or automatic O&M tasks (e.g. SW download, HW configuration request and WBTS restart) cannot be performed in case of Iub O&M connection problem. It is also not possible for the WBTS to report its alarms to controller. This alarm does not indicate a failure in WBTS user plane links.

and WBTS. Try to connect to BTS using BTS Site Manager and deduce the source of the problem with provided information. Error code: 10149 = SWITCHOVER This error code is used if OMU unit switchover has occurred in the RNC and O&M connection to the WBTS has been closed because of that. The WBTS O&M connections are always handled by the OMU unit in WO-EX state so in switchover case the connections are closed. Wait until WBTS opens the O&M connection again and system cancels this alarm. Any other error code: Contact the local Nokia Siemens Networks representative.
Error reason = 2, WBTS id conflict More than one WBTS has been configured with the same id. Error code: 255 = UNSUCCESSFUL An O&M connection for a WBTS id already exists in the RNC. This alarm was set because the same WBTS id was used in new O&M connection establishment from a different IP address that already existing connection was established from. This happens if several WBTS have been configured with the same WBTS id under the same RNC. The supplementary text of alarm gives IP address of the conflicting WBTS. Use BTS Manager to connect the conflicting WBTS with its IP, configure it with a different id. Depending on the WBTS release, the reconfiguration may need to be done using AXC Manager. Cancel the alarm manually after resolving the WBTS id conflict. Cancelling Do not cancel the alarm with error reason 1. The system cancels the alarm automatically when the fault has been corrected.

7761 RNW O&M SCENARIO FAILURE
39 7761 RNW O&M SCENARIO FAILURE Meaning The alarm indicates a failure in some of the following scenarios: - Controller restart - WBTS initialization or WBTS reset - cell initialization, activation or blocking - forced handover - modification of configuration data - pid data updating (storing the process id of the telecom process which is responsible of managing the WBTS/WCELL in question) - WBTS capability information updating - Connection configuration (COCO(IPA-RNC))/IPNB management - Audit handling - Common channel supervision - Common measurement supervision - WBTS recovery (system initiated BTS restart operation) - Iu service barring - Cell deletion - Dedicated measurement initiation These scenarios can be a consequence of either user operation or operation performed by the system. User operation can be, for example, WCEL creation with Element Manager or by plan. Operations performed by the system are in most cases related to recovery operations, for example common channel supervision. In general, all failures cause the cell(s) to be blocked and hence unavailable to traffic. Failure in cell blocking can lead to erroneous cell state information in the controller. Failure in WBTS capability updating or pid updating can cause incorrect WBTS capability data to be used in the controller and thus problems in signalling or actual calls. Failure in User plane configuration (AAL2 path unblocking) causes a situation where the User plane traffic cannot be transferred in the corresponding AAL2 VCC. Supplementary information fields 1

This instruction contains five main steps. The first four steps are specific to certain failure situations. The last step is a general operating procedure for all other failures indicated by this alarm. It is also a default procedure to be performed if instructions given in previous steps do not solve the problem. Abbreviation SIF refers to supplementary information field. Step 1: In case the value of SIF 2 (scenario) is 07 (WBTS reset): - First, verify using Element Manager that WBTS id is valid in the system and COCO (IPA-RNC) is connected to WBTS. - Check also if alarm 7750 FAILURE IN WCDMA BTS O&M CONNECTION is active for this WBTS. If it is active indicating that there is something wrong with WBTS O&M connection (Iub), then reset command cannot be sent from RNC to WBTS. -> If WBTS O&M connection is OK, retry to reset WBTS with Element Manager. -> If WBTS O&M connection between RNC and WBTS is not OK, try to solve the situation with BTS Manager by examining the WBTS alarms and logs. Step 2: In case the value of SIF 2 is 0A (Connection configuration management), and the value of the SIF 1 is 0B (AAL2 path unblocking has failed): - Check the configuration of the corresponding WBTS node using BTS Manager. It should match the configuration of the RNC. - Check that ATM/IP resources related to COCO (IPA-RNC) are

not locked. Locked ATM/IP resources prevent the connection configuration operations. IPA-RNC: - Use MML command ZLAI to print ATM interface information and MML command ZLCI to print VP/VC information (if ATM layer information is given by the user in controller Element Manager). - Unlock the ATM-interface with MML command ZLAS and VP/VC with MML command ZLCS if needed. - If this alarm was generated due to user initiated action, for example COCO (IPA-RNC) creation, try to perform the operation again. Multi-controller RNC or Flexi Direct RNC: Commands "fshclish > show ipnb" can be used to see the IPNB configurations. - If configuration is correct and ATM/IP resources are unlocked, act according to the general operating instructions in step 3 below. Step 3: In case the SIF 2 value is 0D (WBTS recovery) and the value of the SIF 1 is 20 (COCO(IPA-RNC)/IPNB disconnect has failed) or 21 (COCO (IPA-RNC)/IPNB connect has failed): - In case of COCO(IPA-RNC)/IPNB disconnect failure, disconnect the COCO/IPNB manually using Element Manager by removing the WBTS id from the corresponding COCO(IPA-RNC)/IPNB object. Wait at least for 15 seconds and connect the COCO(IPA-RNC) again by restoring the WBTS id to COCO (IPA-RNC)/IPNB object. - In case of COCO(IPA-RNC)/IPNB connect failure, try to connect the COCO(IPA-RNC)/IPNB again to the WBTS using Element Manager. In IPA-RNC if COCO id related to this WBTS is not known, the related COCO id can be found from OMU computer log by searching for process family 50B writings (ZGSC:,50B;) that contain also the WBTS id that this alarm is targeted to. In Multi-controller RNC/Flexi Direct RNC the family 50B logs can be found from location "/srv/Log/log/" in the product. This contains the detailed logs for all the families. Step 4: In case the SIF 2 value is 92 (Dedicated measurement initiation): - Alarm 7778, WCDMA BTS DEDICATED MEASUREMENT FAILURE should be active. Follow the instructions given for that alarm. Step 5: General operation instructions for all other failure reasons: Wait a couple of minutes, system tries to recover from the problem by retrying the failed operation again and the alarm

may be cancelled automatically. In case the alarm is not cancelled due to system recovery while waiting, try to lock and then unlock the cell with controller Element Browser manually. This causes the system to try to clear possible hanging cell related resources and then recreate (init) them. In case the alarm is still active after lock/unlock cell operation, some of the following actions can be tried (each of these causes the WBTS to be unavailable during the operation). These operations clear and again init the BTS related resources: - Reset the WBTS with Element Manager, or - Reform the connection between WBTS and COCO(IPA-RNC) by first disconnecting the COCO (IPA-RNC) and then reconnecting it (this can be done by changing the used COCO(IPA-RNC)id in the WBTS with controller Element Manager) or block/unblock the BTS with BTS element manager. If the alarm still remains active after the steps above, and no obvious reason behind it can be found, collect at least the following logs and contact the local Nokia Siemens Networks representative: IPA-RNC: - OMU computer log, - message monitoring from OMU (families 50B, 4FA, 4EE and 4EF) and serving ICSU (check serving ICSU from COCO(IPA-RNC) (data in Element Manager, monitor families 4FE, 4FB, 4FD, 4B7) during BTS reset Also controller reset might help the situation if it is possible to be performed.

7762 RNW DATABASE OPERATION FAILURE
40 7762 RNW DATABASE OPERATION FAILURE Meaning RNW database operation has failed. This reading or writing operation was tried for some of the following scenarios: - WBTS reset - WBTS initialization - Cell activation - Cell blocking - Cell unblocking - Modification of configuration data - Storing the pids - Storing the WBTS capability information - Storing cch parameters - Cell unlocking - Cell reconfiguration - Controller restart - Audit handling - Iu service barring - Resource status indication handling - Common measurement supervision Depending on the scenario, this failure has led to a situation where cell state could not be modified from blocked to working state or vice versa in controller or it was not possible to send configuration data to WBTS. Failure in pid updating can cause trouble to other O&M scenarios where that information is needed, and failure in WBTS capability updating or CCH parameter updating can cause inconsistent data to be used in controller and thus problems in signalling or in actual calls.

First task: wait for 5 minutes. Typically, there is still some recovery operation ongoing. The alarm gets cancelled if the recovery is successful. If the automatic recovery does not correct the situation, follow these steps: 1. If the blocking reason in the supplementary information field 1 (WCEL state) is 0008 (BL(B)) or 0200 (BL(Ub)), check the WBTS alarm that is related to this WCEL, and follow the operating instructions there. 2. If the blocking reason in the supplementary information field 1 (WCEL state) is 0400 (BL(N)), an incorrect Local Cell Resource id has been given to this cell. Such Local Cell does not exist in the WBTS. The cell data must be corrected and, after that, a WBTS reset is required to remove the problem. 3. If the blocking reason in the supplementary information field 1 (WCEL state) is 0040 (BL(I)) and the value in the supplementary information field 2 (Error code) is 4434 (nbapcmode_netype_mismatch_ec), the NBAP Communication Mode and the Netype do not match. Check the WBTS alarm related to this WCEL, and follow its operating instructions. 4. In case there are no alarms targeted to the WCEL, try to lock and then unlock the cell manually with the controller Object Browser. This way the system tries to clear the possible hanging cell related resources and then recreate (init) them. 5. If the alarm is not cancelled by the lock/unlock cell operation, you can try some of the following actions (the WBTS is unavailable during these operations). These operations first clear and then recreate the BTS related resources: - reset the WBTS with the Element Manager, or - reform the connection between the WBTS and the COCO(IPA-RNC) /IPNB by first disconnecting the COCO(IPA-RNC)/IPNB and then

7772 HSDPA CONFIGURATION FAILED
42 7772 HSDPA CONFIGURATION FAILED Meaning This alarm indicates that there has been an error when controller has requested configuration or reconfiguration of HSDPA channels to BTS via Physical Shared Channel Reconfiguration procedure. The causes which result in this alarm are: - a problem in transmission network between controller and BTS - BTS has rejected the configuration or reconfiguration of HSDPA channels - Controller is unable to send the HSDPA configuration to BTS because of controller internal problems (for example congestion in Iub interface) Location and the nature of the failure can be determined from the supplementary information fields of this alarm. The consequence of this alarm depends on the HSDPA configuration phase. - In case the initial configuration of HSDPA channels fails, the effect is that HSDPA connections cannot be used in this particular cell at all. In this case also the HSUPA connections are unavailable if HSUPA is enabled in the cell. - In case of reconfiguration of HSDPA channels the effect is that the cell may not work with the intended HSDPA parameters.

This action requires cell locking. 03: PWSM HSPA05 reconfiguration failure The problem has occurred during HSDPA reconfiguration to a cell when Power Saving Mode For BTS (PWSM) feature has been making HSPA05 reconfiguration. HSPA05 reconfiguration has been stopped and no cell deletion or activation by PWSM feature will be done. In this case it is recommended to disable PWSM feature. Do cell lock/unlock to recover cell HSDPA parameters and state. If cell is not recovered using lock/unlock operation, a BTS restart can be attempted using Element Manager or BTS Site Manager. The first supplementary information field value indicates the main reason for the problem. 01: No reply from WBTS Problem may reside somewhere in transmission network to BTS. Check if there are other active alarms for the WBTS object and follow the instructions given for those alarms. If there are no apparent problems shown via other alarms, check the type of network problem with following instructions: Precondition for Physical Shared Channel Reconfiguration procedure is that the C-NBAP link to WBTS is working. Check the state of C-NBAP link of this WBTS object from Element Manager main dialog. If the C-NBAP link works, the problem may reside in the BTS. Check the BTS configuration and logs using BTS Manager. If the C-NBAP link does not work, check the success of PING between controller and BTS.

02: BTS rejects the configuration Check that the concerned BTS is in working state using Element Manager. If the working state of the BTS is OK, check that the BTS has correct HW configuration so that HSDPA can be supported (WSPC cards) using BTS Manager. If the working state of the BTS and the BTS HW configuration are OK but this fault still occurs, contact the local Nokia Siemens Networks representative. In case the fault is related to RNW configuration (based on 4th and 5th alarm supplementary information fields of this alarm), check the configuration of this WBTS object in controller using Element Manager, and the configuration in BTS using BTS Manager. Check also if other alarms are active targeted to this same WBTS object. If there are active alarms, proceed according to instructions given for those alarms. If the fault cannot be resolved by correcting the configuration or other BTS alarms, contact the local Nokia Siemens Networks representative. 03: Controller internal error An internal error in controller has occurred during Physical Shared Channel Configuration procedure. If the 6th supplementary information field of this alarm has a value 306, 420, 501, 504, 505, 506, 508, 510 or 529, the situation may be resolved by locking and unlocking the cell. This operation cancels the alarm and triggers the Physical Shared Channel Reconfiguration procedure again. If the problem was only temporary, the alarm should not appear again. If the alarm appears again after a while, check the log writings from the concerned ICSU (IPA-RNC Control plane unit) for example by using MML command ZDDE:ICSU,:"ZGDIC;"; The ICSU unit index to be used is shown in the 3rd supplementary information field of this alarm. To collect the necessary data for troubleshooting, initiate message monitorings in the concerned ICSU unit (IPA-RNC Control plane unit) mentioned in 2nd and 3rd supplementary information fields of this alarm (families 04FE, 04FB) and in active OMU unit.

7773 INSECURE O&M CONNECTION
Multicontroller RNC, IPA-RNC and Flexi Direct RNC Base Station Alarms (7000-7900)
43 7773 INSECURE O&M CONNECTION Meaning The alarm indicates that one or more network elements have established an O&M connection with insecure protocol while the controller is configured in probing security mode. In probing mode the secure connections are preferred, i.e. the alarm may be an indication of a failure in setting up a secure connection. Problems in transport layer or incorrect certificates installation would cause the network element to establish the connection with controller with insecure protocol when the controller is configured in probing mode. Supplementary information fields 1
this represents the actual reason for Controller accepting insecure connection. The field value may indicate: - problems in transport layer Error code: 11728 = TRANSPORT PROTOCOL ERROR 11730 = TRANSPORT SERVICE MISBEHAVIOUR 16654 = TRANSPORT LAYER CAUSE UNSPECIFIED - incorrect certificates installation in the network element Error code: 16212 = NO CERTIFICATES FOUND 16213 = FOUND MULTIPLE CERTIFICATES 17485 = CERTIFICATE IS EXPIRED Instructions
To analyze and correct the problem, check the 1st supplementary information field value. The 1st supplementary information field indicates the reason why the network element is not able to establish the secure connection with the controller when it is in probing mode. To correct the problem, ensure that the correct certificates are installed in the controller as well as in the network element which is trying to establish the secure O&M connection. After the right certificates are installed at the Controller end, operator should trigger the TLSmode as probing which will make Controller to close the server port and open the port with right certificates. Cancelling Do not cancel the alarm. The system cancels the alarm automatically when the fault has been corrected.

7775 INCONSISTENCY IN WCEL CONFIGURATION PARAMETERS
44 7775 INCONSISTENCY IN WCEL CONFIGURATION PARAMETERS Meaning The alarm indicates inconsistency in parameterization between controller and BTS. It may be raised because of these reasons: 1. Nokia Siemens Networks specific configuration parameters in BTS might not be consistent with the parameters in controller. These parameters are CellRange, RACHCapacity, SIB7factor, ShutdownWindow, and ShutdownStepAmount. The situation causing this alarm does not obstruct network operations. 2. The WCEL in the object unit of the alarm has too many adjacencies configured so that the size of the System Information Block (SIB) would exceed the maximum size. In case of parameter inconsistency, the alarm is set when BTS has failed to accept the parameters sent to it during cell setup or when BTS has not responded to the parameter sending during cell setup. The alarm is cancelled automatically after these configuration parameters have been successfully sent to BTS. In case of SIB data encoding failure, the controller has dropped some of the configured adjacencies automatically to enable the SIB sending for the cell and allowing it to be activated. The alarm is cancelled automatically after the adjacency configuration has been modified so that SIB sending can be done normally for the cell. A certain WCEL may have multiple instances of this alarm raised for each different reason simultaneously. The alarm is cell-specific and its indication to NetAct has been prevented by default in IPA-RNC. The controller-specific alarm 3325, INCONSISTENCY IN CONFIGURATION PARAMETERS, is related to this alarm and one instance of it is activated when this alarm has been raised to one or more cells in a certain controller. This controller-specific alarm is sent to NetAct by default. Alarm indication preventions can be altered with MML command AFC in IPA-RNC. Supplementary information fields 1

If these parameter values are the same as those in the BTS Site Configuration File, no actions are needed in controller. Check if other alarms are active for the BTS or WCEL in question. If the cell parameters in controller are not the same as those in the BTS Site Configuration File and these parameters need to be updated, the following actions can be taken to the cell that has failed to accept the parameters sent: * Modify these parameters with Element Manager. This is recommended if the cell works, that is, cell state (WCEL state) is WO. * Lock the cell and then unlock it with Element Manager. This operation causes the parameters to be resent to the BTS. More information about the exact failure reason can be found by examining the error code given in 2nd supplementary information field. Probable error code values are: * 94 = NO RESPONSE BTS has not responded to parameter sending in time or response did not include all the cells the parameters where sent to. * 15472 = WBTS HARDWARE OVERLOAD BTS is temporarily too busy to handle new requests. * 15477 = EQUIPMENT FAILURE A HW failure has occurred. * 15480 = NO RESOURCES IN WBTS Node B resources are unavailable. * 16504 = INTERNAL NBAP ERROR PREVENTING PROCEDURE COMPLETION An internal error that prevents parameter sending has occurred.

7776 HSDPA FAILURE IN WCEL
Multicontroller RNC, IPA-RNC and Flexi Direct RNC Base Station Alarms (7000-7900)
45 7776 HSDPA FAILURE IN WCEL Meaning A major fault (or faults) occurs in the BTS. A unit (or units) that take care of HSDPA traffic in WCEL can be faulty, or there is not enough capacity available in the BTS WSP cards for the HSDPA service. This alarm is set when an HSDPA-capable BTS sends a Resource Status Indication (RSI) message via NBAP to RNC indicating that HSDPA state is changed to "disabled". As a consequence of this alarm, HSDPA connections cannot be used in that particular cell. The RSI message regarding HSDPA disabling can arrive also after the whole cell is reported as "disabled" by BTS via another RSI message. This can happen in BTS recommissioning phase when the cell is disabled in the BTS end as part of the BTS maintenance operations. In this case this alarm can appear together with the alarms for the same WCEL object: 7761 RNW O&M SCENARIO FAILURE 7771 WCDMA CELL OUT OF USE In case the overall WCEL object state is WO (working) when this alarm appears, check the reason for the fault from the BTS WSP-related alarms. Supplementary information fields
Instructions First check the WCEL operational state using RNW RNC Object Browser. If the WCEL operational state is not WO (working), ignore this alarm and analyze the problem with the WCEL taking into account the other active alarms for the same WCEL or its parent WBTS object. If the WCEL operational state is WO, check in the RNC the WSP-related active alarms that are targeted to the related WBTS object. The alarms to be checked are: 7650 BASE STATION FAULTY 7651 BASE STATION OPERATION DEGRADED 7652 BASE STATION NOTIFICATION The faulty unit is mentioned in supplementary information field 3 of these alarms. Check all WSP-related alarms because any of the WSP-related fault can be the reason for this alarm. If a HSDPA-dedicated WSPC unit in BTS is faulty, the BTS reserves another WSPC when it becomes free from other traffic. For more information on BTS alarms, see WCDMA BTS Alarm

First, check if there are other alarms active for the BTS in question and follow the instructions given for those alarms. This alarm is cancelled if the problem is solved by correcting the other active alarms. If there are no obvious faults indicated by active alarms and this alarm is not cancelled by system, follow the instructions given in the steps below according to error code given in the first supplementary information field. 1. Error code 13247 no_answer_from_remote_end_ec 15479 nbap_bts_hw_res_not_avail_ec
No response from BTS BTS hardware failure
These codes indicate that response from BTS was not received for Dedicated Measurement Indication or BTS hardware failure. The operation can be retried by creating the corresponding NBAP-D again using Element Manager (this operation causes all the cells of the BTS being unavailable for traffic): 1) Lock all the cells under the BTS. 2) Remove the WBTS id from the COCO(IPA-RNC)/IPNB.

3) Add the WBTS id to the COCO(IPA-RNC)/IPNB again. 4) Unlock these cells. If creating the NBAP-D again does not help, the problem may reside on the BTS end. It should be analyzed by connecting to corresponding BTS using BTS Manager. 2. Error code 13288 dst_link_failure_ec 13846 no_resp_from_serv_provider_ec
NBAP-D link has been down NBAP-D process no response
The operation in step 1 can be attempted, it may help if the problem was only temporary. If the operation in step 1 does not help, the communication problem between controller processes should be analyzed by taking message monitoring from controller OMU when the unlocking of the cells is done. See the last part of this instruction for information about collecting the needed monitorings and logs. 3. Any other error code: Try to perform NBAP-D link creation again using instructions given in step 1.
If this doesn't help, a BTS restart may be attempted to solve the situation. If the problem persists after these steps, contact the local Nokia Siemens Networks representative. Attach OMU message monitorings for troubleshooting: IPA-RNC: For process 3C6, all of ICSUs message monitoring for process 4FE, OMU computer log and error log (MML-commands ZDDE::"ZGSC"; and ZDDE::"ZGLE";), and alarm history (MML-command ZAHP or using Fault Management application in controller EM). Multi-Controller RNC or Flexi Direct RNC: Message monitoring for families can be collected from location "/srv/Log/log/" in the product. Also alarm history can be collected by using SCLI command "fsclish -c "show alarm history"" or using Fault Management application in controller EM. Cancelling Do not cancel the alarm. The system cancels the alarm automatically when the fault has been corrected.

7780 HSUPA FAILURE IN WCEL
Multicontroller RNC, IPA-RNC and Flexi Direct RNC Base Station Alarms (7000-7900)
48 7780 HSUPA FAILURE IN WCEL Meaning A major fault (or faults) occurs in the BTS. A unit (or units) taking care of HSUPA traffic in the WCEL can be faulty, or there is not enough capacity available on the BTS WSP cards for HSUPA service. This alarm is set when an HSUPA-capable BTS sends a Resource Status Indication (RSI) message via NBAP to the RNC indicating that HSUPA state is changed to "disabled". As a consequence of this alarm, HSUPA connections cannot be used in that particular cell. The RSI message regarding HSUPA disabling can arrive also after the whole cell is reported as "disabled" by BTS via another RSI message. This can happen in BTS recommissioning phase when the cell is disabled in the BTS end as part of the BTS maintenance operations. In this case this alarm can appear together with the alarms for the same WCEL object: 7761 RNW O&M SCENARIO FAILURE 7771 WCDMA CELL OUT OF USE In case the overall WCEL object state is WO (working) when this alarm appears, check the reason for the fault from the BTS WSP-related alarms. Supplementary information fields
Instructions First check the WCEL operational state using RNW RNC Object Browser. If the WCEL operational state is not WO (working), ignore this alarm and analyze the problem with the WCEL taking into account the other active alarms for the same WCEL or its parent WBTS object. If the WCEL operational state is WO, check in the RNC the WSP-related active alarms that are targeted to the related WBTS object. The alarms to be checked are: 7650 BASE STATION FAULTY 7651 BASE STATION OPERATION DEGRADED 7652 BASE STATION NOTIFICATION The faulty unit is mentioned in supplementary information field 3 of these alarms. Check all WSP-related alarms because any of the WSP-related faults can be the reason for this alarm. If a HSUPA-dedicated WSPC unit in the BTS is faulty, the BTS reserves another WSPC when it becomes free from other traffic. For more information on BTS alarms, see WCDMA BTS Alarm

7782 HSUPA CONFIGURATION FAILED
Multicontroller RNC, IPA-RNC and Flexi Direct RNC Base Station Alarms (7000-7900)
50 7782 HSUPA CONFIGURATION FAILED Meaning This alarm indicates that there has been an error when controller requested configuration or reconfiguration of HSUPA channels to BTS via Physical Shared Channel Reconfiguration (PSCR) procedure. The possible causes which result in this alarm are: - There has been a problem in transmission network between controller and BTS. - BTS has rejected the configuration or reconfiguration of HSUPA channels. - Controller is unable to send the HSUPA configuration to BTS because of controller internal problems (for example congestion in Iub interface) Location and the nature of the failure can be determined from the supplementary information fields of this alarm. The consequence of this alarm depends on the HSUPA configuration phase where the failure occurred. - If the failure occurred in the initial HSUPA configuration or in delivering the HSUPA parameters to the BTS, the HSUPA connections cannot be used in this particular cell at all. - If the failure occurred in the reconfiguration of the HSUPA, the effect is that the cell may not work with the intended HSUPA parameters.

The 8th supplementary information field value indicates the phase in which the problem has occurred: 01: Delivering HSUPA parameters to BTS 02: Initial HSUPA configuration The problem has occurred during initial HSUPA setup to a cell. The effect of this is that HSUPA cannot be used in the cell. Proceed to the step 2 in this instruction. 03: Reconfiguration of HSUPA The problem has occurred during HSUPA reconfiguration to a cell. The effect is that the HSUPA may not work with the intended parameters. In this case it is recommended that HSUPA is disabled and enabled in the cell to confirm that proper parameters are taken into use. This action requires cell locking. 04: PWSM HSPA05 reconfiguration failure The problem has occurred during HSUPA reconfiguration to a cell when Power Saving Mode For BTS (PWSM) feature was performing HSPA05 reconfiguration. HSPA05 reconfiguration has been stopped and no cell deletion or activation by PWSM feature is done. In this case it is recommended to disable PWSM feature.

procedure is that the C-NBAP link to WBTS is active. Check the state of C-NBAP link of this WBTS object from Element Manager main dialog. If the C-NBAP link works, the problem may reside in the BTS. Check the BTS configuration and logs using BTS Manager. If the C-NBAP link does not work, check the success of PING between controller and BTS. Successful PING tells that the BTS is up and running: MML command: ZQRX (IPA-RNC) Normal Ping command : Multi-controller RNC/Flexi Direct RNC If ping does not succeed, then the problem is in lower level of the transmission network. Check physical connections in network. If ping succeeds, then the problem is in application level. In many cases there is also more information in OMU computer log. IPA-RNC : Logs can be studied with MML-command ZDDE::"ZGSC"; Multi-Controller RNC or Flexi Direct RNC: Logs can be collected and studied from location "/srv/Log/log/" in the product. 02: BTS rejects the configuration Check that the concerned BTS is in working state using controller Element Manager. If the working state of the BTS is OK, check that the BTS has correct HW configuration so that HSUPA can be supported (WSPC cards) using BTS Manager. If the working state of the BTS and the BTS HW configuration are OK, but this fault still occurs, contact the local Nokia Siemens Networks representative. In case the fault is related to RNW configuration (based on the 4th and the 5th alarm supplementary information fields of this alarm), check the configuration of this WBTS object in controller using Element Manager, and the configuration in BTS using BTS Manager. Check also if other alarms are active targeted to this same WBTS object. If there are active alarms, proceed according to instructions given for those alarms. If the fault cannot be resolved by correcting the configuration or other BTS alarms, contact the local Nokia Siemens Networks representative. 03: Controller internal error An internal error in controller has occurred during Physical

If the 6th supplementary information field of this alarm has a value 306, 420, 501, 504, 505, 506, 508, 510 or 529, the situation may be resolved by locking and unlocking the cell. This operation cancels the alarm and triggers the Physical Shared Channel Reconfiguration procedure again. If the problem was only temporary, the alarm should not appear again. If the alarm appears again after a while, check the log writings from the concerned ICSU, for example by using MML command ZDDE:ICSU,:"ZGDIC;"; The ICSU unit index to be used is shown in the 3rd supplementary information field of this alarm. To collect the necessary data for troubleshooting, initiate message monitorings in the concerned ICSU (IPA-RNC Control plane unit) mentioned in the 2nd and the 3rd supplementary information fields of this alarm (families 04FE, 04FB) and in active OMU unit. In Multi-Controller RNC and Flexi Direct RNC the detailed family logs can be collected from location in the product "/srv/Log/log/".

Multicontroller RNC, IPA-RNC and Flexi Direct RNC Base Station Alarms (7000-7900)
52 7784 RECOVERY ACTION FAILURE Meaning This alarm indicates that automatic WCDMA BTS recovery action performed by controller has failed. The recovery has been attempted because some of the WCELs under the WBTS have been detected not to be performing properly. The observed cause for the recovery is given in alarm supplementary information. For more information about the recovery functionality behind this alarm, see feature descriptions for features RAN1302 and RAN1810 in Product Documentation. The reason for the recovery failure is one of the following: - The amount of WBTS recovery actions (restarts) have been used up for a specific WBTS object for the current day. - BTS restart failed due to missing BTS O&M connection. - BTS does not respond to restart request. - BTS is busy handling software upgrade and rejects the restart request. As a result of this alarm the traffic handling capacity of the WCDMA BTS may be reduced because some WCELs do not perform properly. Recovery action is resumed by controller again after the fault preventing the recovery action has been corrected and if the problem affecting the WCEL performance still remains.

this value indicates the allowed amount of WBTS recovery actions (restarts) per day. It is defined in PRFILE parameter RN22_FEATURE_OPT_009 (002:1296). Instructions
Check the reason for the recovery failure from the 1st supplementary information field and proceed accordingly. 00: The amount of performed BTS restarts as recovery action per day exceeds the limit which is given in the 4th alarm supplementary information field. In this case the BTS cannot be restarted by controller until next midnight when controller resets the BTS specific restart amount counters. The BTS can be recovered manually by restarting it using either Element Manager or BTS Site Manager. Increasing the allowed BTS restart amount in PRFILE enables controller to perform additional restarts for BTS sites that have no recovery attempts left. 01: BTS O&M connection between BTS and controller is not available and restart could not be performed. See if controller alarm 7750 is active for possible details on the fault concerning the BTS O&M connection. Check also the status of BTS O&M connection from BTS Site Manager. See instructions below for possible need to perform manual recovery actions depending on the 2nd supplementary information field value. 02: BTS does not respond to the reset request. This may be due to high load in BTS side. Check the BTS status using BTS Site Manager and restart the BTS manually if possible.

This means that during recovery actions the whole WBTS can become unavailable, but the reason can change. For example, it is possible that the BRM hand crash causes the original problem, but after its recovery the C-NBAP link can be unavailable. The original alarm is kept active, as from the system point of view the whole WBTS is still unavailable. To analyze and correct the problem, check the 1st supplementary information field value. 00: C-NBAP link break

This can be caused by different underlying reasons that are indicated as the C-NBAP link break to RNW O&M: - a transmission break between controller and BTS resulting from, for example, a cable or external transmission equipment failure, a BTS restart performed using BTS Site Manager, or a controller network interface unit failure. - an internal controller failure, for example a spontaneous ICSU (IPA-RNC)/ Control plane unit (Multi-controller RNC/Flexi Direct RNC) restart. In case of the C-NBAP link failure the recommendation is to wait for a couple of minutes and check if the disturbance is only temporary. The system recovers automatically once the transmission between the controller and BTS is available again. In case of a longer WBTS unavailability, it can be checked if the controller has active alarms for (IPA-RNC)/ Control plane unit (Multi-controller RNC/Flexi Direct RNC) or network interface units that can cause the C-NBAP link unavailability. The relation between WBTS and (IPA-RNC)/ Control plane unit (Multi-controller RNC/Flexi Direct RNC) unit can be seen from WBTS data using the Element Manager (the controller GUI for BTS Connection Resources dialog). 01: BRM hand crash The system recovers from the situation automatically. This reason may trigger non-performing cell recovery actions in controller, meaning that the BTS gets restarted by the controller. 02: Link switch failure during rebalancing operation This value is valid only in Multi-controller RNC and it indicates that the link switch for this BTS from donating CSCP to receiving CSCP has failed. This situation cannot be recovered automatically. WBTS-IPNB needs to be disconnected and then connected again to recover this WBTS. As for the behavior of this alarm when the WBTS level failure indication in feature RAN1461 state is changed, note the following: 1. When the WBTS level fault functionality is switched from OFF to ON state, there are no effects on the existing WCEL alarms under a certain WBTS. The effect can be seen on the following alarms set by the system. 2. When the WBTS level fault functionality is switched from ON to OFF state, and if this alarm is active for a WBTS, the functionality for this particular WBTS is still considered as working. This means that the WBTS level failure alarm is kept active as long as all the WCELs for that WBTS remain unavailable.

7794 ALARM STATUS REQUEST HAS TIMED OUT
Multicontroller RNC, IPA-RNC and Flexi Direct RNC Base Station Alarms (7000-7900)
54 7794 ALARM STATUS REQUEST HAS TIMED OUT Meaning The alarm indicates that due to the lack of the upload acknowledgement message from the BTS, the alarm upload cannot be started between the BTS and the controller. The alarm is set when two consecutive alarm upload requests have been sent by the controller without an acknowledgement from the BTS. If this alarm occurs, there can be a difference in alarm conditions between the controller and the BTS. The precondition to set this alarm is that the BTS O&M link is active. If the BTS O&M link is not active at the moment of the alarm upload attempt, alarm 7750 is set instead. Supplementary information fields
Instructions No actions are needed in the controller. Use the BTS Site Manager to see the operation status in the BTS end for an additional troubleshooting. Cancelling Do not cancel the alarm. The system cancels the alarm after the BTS has acknowledged the alarm upload status request and when the upload can be started.

7795 INCONSISTENCY IN HIGH PEAK RATE HSPA CONFIG
55 7795 INCONSISTENCY IN HIGH PEAK RATE HSPA CONFIG Meaning The alarm indicates that the High Peak Rate HSPA configuration parameters (for DC HSDPA or Dual Band HSDPA or HSUPA IC) in at least one WCEL of the BTS might not be consistent with the parameters in the RNC. In DC HSDPA case this alarm is also raised if the BTS loses its capability of supporting DC HSDPA. This is also a result if user locks one of the cells in the cell pair during maintenance activities. The situation causing this alarm does not obstruct network operations. The alarm is cell-specific, and not indicated to NetAct by default. Instead, the RNC-specific alarm 3325, "INCONSISTENCY IN CONFIGURATION PARAMETERS", is reported on NetAct when first instance of 7795 is set. The alarm 7795 is cancelled by the system when configuration at BTS and RNC is consistent for High Rate HSPA features (DC HSDPA, Dual Band HSDPA and HSUPA IC) or when the cell is deleted/locked. Alarm indication preventions can be altered with MML command AFC in IPA-RNC. Supplementary information fields 1

The situation causing this alarm does not obstruct network operations, and therefore no immediate actions are required. However, you can take the following actions to ensure consistency in configuration parameters. In case of DC HSDPA related problem, check first that the cell pair of the cell indicated in this alarm is not locked by user before proceeding to the steps given below. If that is the case, then the eventual unlocking of the DC HSDPA cell pair will clear this alarm. 1. Find the cells that might have inconsistency in configuration parameters by checking the alarms in the RNC. For these cells, proceed to step 2. 2. a) If the 2nd supplementary information field value is "DCHSDPA": Check the cell parameter WCEL - DCellHSDPAEnabled in the RNC using the OMS EM. BTS may reject the Dual Cell HSDPA configuration if the HW mapped for the Cell is not supporting HSPA, or if the frequency configuration is not properly done, so: - Check from BTS side that the HW mapped to the Cell resource is capable of providing HSPA. - Check from RNC side that the WCEL UARFCN configuration is done according to instructions given in RAN1906 feature activation manual. - If configuration parameters have inconsistency then lock the cell, correct WCEL UARFCN configuration as well as other parameterization as mentioned in RAN1906 feature activation manual. - Unlock the cell if were locked in previous step. b) If the 2nd supplementary information field value is "HSUPAIC": Check the cell parameter WCEL - AdminPICState in the RNC using the OMS EM. If AdminPICState is "enabled" then this alarm indicates that BTS failed to configure HSUPA IC. If AdminPICState is "disabled" then it indicates that BTS has not disabled HSUPA IC even though configuration at RNC is changed to disable HSUPA IC. In such cases, proceed to step-3. c) If the 2nd supplementary information field value is "DBHSDPA": Check the cell parameter WCEL- DBandHSDPAEnabled in the Controller using the OMS EM. BTS may reject the Dual Band HSDPA configuration if the HW mapped for the Cell is not supporting HSPA, or if the frequency configuration is not properly done, so: - Check from BTS side that the HW mapped to the Cell resource is

capable of providing HSPA. - Check from RNC side that the WCEL UARFCN configuration is done according to instructions given in RAN1906 feature activation manual. - If configuration parameters have inconsistency then lock the cell, correct WCEL UARFCN configuration as well as other parameterization as mentioned in RAN1906 feature activation manual. - Unlock the cell if were locked in previous step. 3. Check if there are any BTS end failures that are indicated with 76xx alarms and that could affect this feature (e.g. some HW unit failure) Check if the relevant BTS is in the working state using the OMS EM. If the working state of the BTS and the BTS HW configuration are correct while this fault still occurs, contact the local Nokia Siemens Networks representative. More information about the exact failure reason can be found by examining the 1st supplementary information field (error code). You can check its meaning in IPA-RNC with a command of the service terminal extension MRS (see Service Terminal Essentials, Maintenance Manual), in multi-controller RNC / Flexi Direct RNC using CLI command "dxserrcli " or from the document General Error Messages of System, Supplementary References. For more information about configuring DC HSDPA and DB HSDPA features, see the respective feature activation manuals in product documentation. Cancelling Do not cancel the alarm. The system cancels the alarm after the BTS has indicated to the RNC that it supports the high peak rate HSPA feature in the cell in case of DC HSDPA or Dual band HSDPA or BTS and RNC has consistent PIC States in case of HSUPA IC. The alarm will also be cancelled when the cell is deleted or locked.

7796 HIGH SPEED COMMON CHANNEL PROBLEM
Multicontroller RNC, IPA-RNC and Flexi Direct RNC Base Station Alarms (7000-7900)
56 7796 HIGH SPEED COMMON CHANNEL PROBLEM Meaning This alarm indicates a failure in HS FACH or HS RACH common channels in the cell. It is set for the cell when - the creation of HS FACH/HS RACH common channel fails - the capability of the WCEL mismatches with HS FACH/HS RACH capability on BTS side - HS FACH/HS RACH common channels are unavailable due to sync loss between BTS and RNC. If this alarm is raised, then UE DRX feature becomes out of use (if it was already enabled) as both features (HS FACH and HS RACH) are pre-requisite for operation of UE DRX feature. Supplementary information fields 1
error code, possible values are: - 1315d = High speed cell FACH is enabled in the controller but Disabled or not supported in the BTS. - 1316d = Synchronization between the BTS and controller is lost for HS FACH channels and those are unavailable. - 1914d = High Speed Cell FACH UL is enabled in the controller but disabled or not supported in the BTS. - Besides these above specific error code, there can be other error code corresponding to failures identified during High Speed FACH/ HS RACH channel creation. For instance, insufficient DSP resources. Instructions
Case 1) The first supplementary information field value is 1315d (enh_fach_capb_mismatch_ec). Possible reasons: - There is a mismatch of the HS-DSCH channel configuration between the controller and BTS. - BTS HW does not support HS FACH common channels - BTS runs out of capability due to, for example, a HW failure. Actions to be taken: 1)

2)
7796 HIGH SPEED COMMON CHANNEL PROBLEM
Check if the relevant BTS is in the working state using the controller Element Manager. If so, check whether the BTS HW configuration is correct so that Enhanced HSFACH can be supported. If the working state of the BTS and the BTS HW configuration are correct while this fault still occurs, contact the local Nokia Siemens Networks representative.
Case 2) When the first supplementary information field value is 1316d (hs_cch_sync_ec): Possible Reason: Synchronization between the controller and BTS is lost for the HS FACH common channel. Actions to be taken: The continuous recovery is performed by the controller. An attempt can be made to solve the problem by locking and unlocking the cell manually. Case 3) The first supplementary information field value is 1914d (enh_rach_capb_mismatch_ec). Possible reasons: - There is a mismatch of the E-DCH channel configuration between the controller and BTS. - BTS HW does not support HS RACH common channels - BTS runs out of capability due to, for example, a HW failure. Actions to be taken: 1) If the fault is related to the RNW configuration, check the E-DCH configuration of this WBTS object in the controller using the Element Manager, and the configuration in the BTS using the BTS Manager. 2) Check if the relevant BTS is in the working state using the controller Element Manager. If so, check whether the BTS HW configuration is correct so that Enhanced HS RACH can be
supported.

are correct while this fault still occurs, contact the local Nokia Siemens Networks representative.
If the fault cannot be fixed by correcting the configuration, checking other BTS alarms, or continuous recovery attempts on the cell, contact the local Nokia Siemens Networks representative. For information on the exact reason of the failure, see the 1st supplementary information field. You can check its meaning with a command of the service terminal extension MRS (see Service Terminal Essentials, Maintenance Manual) or in the document General Error Messages of System, Supplementary References. For more information, you can also examine the OMU computer log accessed with the MML command ZDDE::"ZGSC" in IPA-RNC and in Multi-Controller RNC/Flexi Direct RNC logs can be found at location in the product "/srv/Log/log/". Cancelling Do not cancel the alarm. The system cancels the alarm automatically when the fault has been corrected. The alarm is cancelled when either of the following occurs: - The creation of HS FACH/HS RACH common channel in the cell is successful. - The cell is deleted from the Node-B. - The cell is deleted internally from the controller as a result of the audit procedure. Any earlier instance of this alarm in a WCEL is cancelled when the alarm is set with cause 1315d (enh_fach_capb_mismatch_ec). Any earlier instance of this alarm raised to indicate the transport channel failure with cause 1316d (hs_cch_sync_ec) is cancelled when the request for setting the alarm is received with any another cause for the same cell.
