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,

INSTRUCTIONS: FlexiBTS:
1. Make sure that the module is properly connected. If the
module LED does not light up, the module is faulty. Check
the alarming module.
In case of two FSM-r3, check also SRIO cable connection
between the system modules.
2. Check the fault history.
FlexiLiteBTS: Check the fault history.
UltraSite, MetroSite, MetroSite 50, Triple-mode,
UltraSite/EUBB:
1. Check the fault history, alarming unit and subrack.
2. If the SW has been updated recently, reload the SW.
3. If the WAF or WIC is alarming, try recommissioning the
site.
4. Make sure that the unit is properly connected. If the
unit LED does not light up, the unit is faulty. The fault
might also be in the WPS unit or backplane.
5. Check the power cables, connectors, and the I2C bus
cables.
Cancel alarms: Removing and inserting the WIC, WSM or
primary WAM causes a site reset. If both WSCs are removed,
inserting the first removed WSC back into the cabinet
causes a site reset.
If the 7650 BASE STATION FAULTY alarm is issued, reset the
site. First, try to reset the site with the software. If
that does not help, replace the alarming unit.
If the WSMF unit is not present (replaced by WSMB)in BTS,
alarming WSPFs are not used and should be removed from BTS.
WSPFs can be removed, because without a WSMF unit BTS works
as UltraSite not as EUBB.

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

: 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.

UltraSite, MetroSite, MetroSite 50, Triple-mode,
UltraSite/EUBB:
1. Check the fault history, alarming unit and subrack.
2. If the SW has been updated recently, reload the SW.
3. If the WAF or WIC is alarming, try recommissioning the
site.
4. Make sure that the unit is properly connected. If the
unit LED does not light up, the unit is faulty. The fault
might also be in the WPS unit or backplane.
5. Check the power cables, connectors, and the I2C bus
cables.
Cancel alarms: Removing and inserting the WIC, WSM or
primary WAM causes a site reset. If both WSCs are removed,
inserting the first removed WSC back into the cabinet
causes a site reset.
If the 7650 BASE STATION FAULTY alarm is issued, reset the
site. First, try to reset the site with the software. If
that does not help, replace the alarming unit.
If the WSMF unit is not present (replaced by WSMB)in BTS,
alarming WSPFs are not used and should be removed from BTS.
WSPFs can be removed, because without a WSMF unit BTS works

: The oven oscillator adjusting area is reaching its limit
value. 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).
Note that if the alarm 7651 BASE STATION OPERATION
DEGRADED: 'WMC 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 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. Transport part
- First check the alarms of the AXC node with the AXC
Manager and act accordingly.
- If there are no alarms, check the AXC synchronisation
settings.
b. WMC unit

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.

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. The BTS fault
descriptions are also included in BTS SW release

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.

: 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.

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.

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

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

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. Note: In

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.

: WSC phase difference jammed to zero reading
: 22: EFaultId_WscPhaseDiffJammedAl
: The WSC phase measurement is jammed and the tuning

The problem can be caused by a WSC fault, or a too fast

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.
Background information: The principle in the mobile network
is that the synchronization goes from MSC => RNC => BTS.

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

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).

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 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

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. For more information, see base station fault
descriptions in WCDMA RAN and Flexi Direct System Libraries.

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.

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.

-> 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.

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.

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.

The alarm is set when one of the following situations occurs:
1. WCEL state is changed from
- WO -> BL(B), bl- WBTS
- WO -> BL(S), bl- system failure
- WO -> BL(I), bl- init
- WO -> BL(L), bl- C-NBAP link failure

- WO -> BL(Ub), bl- Blocked by user locally from WBTS
It is possible that the WCEL state changes first from WO
to BL(H) (bl - shutting down) and only after that to one
of the above mentioned states. This alarm is not set
when the WCEL state changes from WO to BL(H), but it is
set when the BL(H) state is replaced by one of the
above mentioned blocked states.
2. WCEL is unlocked and the COCO(IPA-RNC)/IPNB connection
operation has been performed, but the state of the WCEL
does not change to WO.
3. COCO(IPA-RNC)/IPNB connection operation has been performed, the
WCEL has been unlocked, but the state of the WCEL does not
change to WO.
4. An incorrect Local Cell Resource id has been given to this
cell. Such a Local Cell does not exist in the WBTS.
5. The NEType indicated by the BTS and the NBAP Communication

Instructions

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

or
- block/unblock the BTS with the BTS element manager.
If the alarm is still active after the above operations have been
performed, 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 (service terminal command ZGSC),

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. 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

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

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,<index>:"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

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

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

- 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.

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.

Case 1: If the alarm reason given in the first supplementary
information field is INCONSIS:
Check the cell parameters CellRange, RACHCapacity, SIB7factor,
ShutdownWindow and ShutdownStepAmount in controller using Element
Manager. 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.
In these fault cases the actions mentioned above should repair the
situation. Fault cases with error code EQUIPMENT FAILURE may also
require repairing of BTS HW.

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.

Instructions

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

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).

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.

Instructions
Step 1:
Check first the nature of the problem. 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. Do cell lock/unlock to
recover cell HSUPA 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.
Step 2:
The first supplementary information field 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

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.

Meaning
One or more IP-based D-NBAP links of a WCDMA BTS are detected lost
by the controller.
The user plane traffic handling capability of the WCDMA BTS is
degraded, or the traffic capability of the whole WCDMA BTS is
totally lost.
This alarm is set only if the fault is detected in IP-based D-NBAP
link(s) of the WCDMA BTS. The alarm is not set for IP-based D-NBAP links
if the C-NBAP link is unavailable at the same time.
Supplementary information fields

Instructions

See the NBAP link operational states for the WCDMA BTS from Topology
Browser in controller OMS to see which of the configured D-NBAP links
are unavailable.
In case this alarm is set right after the WBTS is enabled in the system,
verify using Topology Browser that the IPNB object configuration
in controller is correct in relation to the network setup.
Otherwise, the problem is likely to be located either in the BTS or in IP
transmission between the BTS and the controller. See other possible
active BTS-originated alarms (7650, 7651) that can indicate the
reason for the failure.
Use BTS Site Manager to see the operation status in the BTS end for

7784 RECOVERY ACTION FAILURE

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.

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.
See instructions below for possible need to perform manual recovery
actions depending on the 2nd supplementary information field value.
03: BTS software upgrade is ongoing and BTS cannot be restarted at the
moment. BTS restarts after the software upgrade has been completed.
04, 05, 06:
Unexpected error has occurred in BTS O&M message handling. The
reason might be that controller and BTS do not use compatible
version of the BTS O&M interface. Collect OMU computer log
from controller and also logs from the BTS in question. Fill in a

7786 WCDMA BASE STATION OUT OF USE

53 7786 WCDMA BASE STATION OUT OF USE
Meaning
This alarm indicates that there is a WBTS-level failure that causes
all the WCELs in the WO state under this specific WBTS to become
unavailable.
This alarm is set when a known fault occurs and makes all
the WCELs under a certain WBTS to become unavailable at once.
The reasons for this are the C-NBAP link break or Base Station
Resource Manager (BRM) hand crash in the controller.
As a result of this alarm, the whole WBTS is unavailable for traffic.
There can be also individual WCEL level alarms active for the WCELs
of this WBTS if they were active prior to the WBTS level failure
detection.
This alarm is set only if there is at least one cell in the WO state
under the WBTS.
This alarm is canceled when at least one WCEL under the WBTS is
recovered back to the WO state, or if the user locks all the WCELs
under the WBTS.
For more information on this functionality, see Nokia Siemens
Networks WCDMA RAN documentation concerning feature RAN1461.
Supplementary information fields

reason why all the WCELs became unavailable at once. The possible
reasons are:
00 = C-NBAP link break
01 = BRM hand crash
02 = Link switch failure during rebalancing operation
Instructions

The 1st supplementary information field indicates the reason why
the whole WBTS became unavailable. The field contains the
first observed reason for the problem. 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.

7786 WCDMA BASE STATION OUT OF USE

Multicontroller RNC, IPA-RNC and Flexi Direct RNC
Base Station Alarms (7000-7900)

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.

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.

Instructions

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

- 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 <error code>" 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.
