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 7.0.2.0 release. In case of earlier SW
release and in case you need more detailed fault
descriptions refer to WCDMA RAN and I-HSPA System
Libraries. The BTS fault descriptions are also included in

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 WSMF unit BTS works as
UltraSite not as EUBB.
FlexiBTS:
1. Check that the module is properly connected. If the
module LED does not light up, the module is faulty. Check
the alarming module.
2. Check the fault history.

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

: 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 because the device type is not known,
detailed instructions cannot be given - refer to the
appropriate user manual of the device for further actions.
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

Base Station Alarms (7000-7900)
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 instability of
the transmission network, 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 performing a BTS site reset does not help, replace
the System Module.

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:

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:

- If both the Iub reference signal accuracy and the AXC
node are in order but the WMC unit is still alarming, run
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).

: 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 because the device type is not known,
detailed instructions cannot be given - refer to the
appropriate user manual of the device for further actions.
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 instability of
the transmission network, 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 performing a BTS site reset does not help, replace
the System Module.

: Difference between BTS master clock and reference frequency

from the transport part has changed by about 0.2 ppm or
more (which equals the change magnitude of 204 DAC steps or

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).
UltraSite, MetroSite, MetroSite 50, Triple-mode:
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: Because there are several possibilities for the alarm
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,

Base Station Alarms (7000-7900)
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.

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 reseted (either by manager command, by
power outage or by a GPS recovery reset). This means that
if the GPS receiver installation quality is only an average
- and specially 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.

1. Absolutely the most common reason for this fault
indication is that the GPS antenna installation has not
been done properly, that is the sky visibility is not good
enough. Please refer the documentation for installations
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.

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
noticed that the position has changed and the receiver has
started an automatic survey. Please notice also that
automatic survey takes place every time during first
start-up.
2. If the automatic survey takes place every now and then,
it might be an indication that the sky visibility is poor
and according to the poorly tracked satellites, the GPS
receiver concludes that the position has changed. In this
case, check the activity of the other faults (BTS fault
history data) and if found feasible, make re-installation
of the GPS antenna.
3. If the GPS installation is good but still the automatic
survey takes place every now and then, there might be a
malfunction in the GPS receiver. Perform a (remote) power

: WSC oven oscillator fault
: 907: EFaultId_DualWscDacWordAlarm
: The oven oscillator adjusting area is reaching its limit
value. The alarm is activated if the WSC 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 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),

- 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.

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.
But in reality that chain might be broken somewhere and,
for example, when using leased lines the BTS may take the

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 WN7.0.2.0 release. In case of earlier SW
release and in case you need more detailed fault
descriptions refer WCDMA RAN and I-HSPA System Libraries.

A major fault (or faults) has occurred in a unit/module (or
units/modules) that belong to the sector indicated in the alarm.
Check the reason for the fault from the supplementary text field
of the alarm.
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 I-HSPA System Libraries.

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 WN7.0.1.0 release. In case of earlier SW
release and in case you need more detailed fault
descriptions refer to WCDMA RAN and I-HSPA System
Libraries. The BTS fault descriptions are also included in

Check the reason for the fault from the supplementary text field
of the alarm.
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 I-HSPA System Libraries.

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 WN7.0.2.0 release. In case of earlier SW

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 I-HSPA 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 I-HSPA System Libraries.

: 61073: ROUTING_MISCONFIGURATION
: A routing misconfiguration was detected. A
management-plane, control-plane, a synchronization-plane
packet, or a CES-packet was sent over a network interface
for which it was not intended, as configured in the
application IP addresses. Or a user-plane packet was sent
over a network interface for which the 6 PHB priority queue
scheduler was not activated by the operator.
Since the actual egress network interface is selected based
on the static routing table entries, a misconfiguration of
the static routing table is suspected.

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. The
states of the user plane links can be checked using OMS Topology
Browser.

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

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.

Multicontroller RNC, IPA-RNC and I-HSPA Adapter
Base Station Alarms (7000-7900)
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.

Instructions
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/I-HSPA ADA:
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/I-HSPA ADA 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.
More information about the exact failure reason can be found by
examining the supplementary info field 3 (error code). You can check
its meaning with a command of the service terminal extension MRS
(see Service Terminal Essentials, Maintenance Manual) or from the

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.

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

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

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.

field value indicates the phase in which the problem has occurred:
01: Initial HSDPA configuration
The problem has occurred during initial HSDPA setup to a cell. The
effect of this is that HSDPA cannot be used in the cell.
02: Reconfiguration of HSDPA
The problem has occurred during HSDPA reconfiguration to a cell. The
effect is that the HSDPA may not work with the intended parameters.
In this case it is recommended that HSDPA is disabled and enabled

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/I-HSPA ADA
If ping does not succeed, then the problem is in lower level
of the transmission network. Check physical connections in
the network. If ping succeeds, then the problem is in
application level.

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
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.

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

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

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.

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

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.

7780 HSUPA FAILURE IN WCEL
Multicontroller RNC, IPA-RNC and I-HSPA Adapter
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.

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
type of network problem with the following instructions:

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/I-HSPA ADA
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/I-HSPA ADA :
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.

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/I-HSPA ADA the detailed family logs can be
collected from location in the product"/srv/Log/log/".
Start the Physical Shared Channel Reconfiguration procedure by
locking and unlocking the cell and wait for the alarm to be set

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.

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

reason why all the WCELs became unavailable at once. The possible
reasons are:
00 = C-NBAP link break
01 = BRM hand crash
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.
00: C-NBAP link break
This can be caused by different underlying reasons that

Multicontroller RNC, IPA-RNC and I-HSPA Adapter
Base Station Alarms (7000-7900)
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/I-HSPA ADA)
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/I-HSPA ADA) 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/I-HSPA ADA) 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.
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.
Cancelling
Do not cancel the alarm. The system cancels the alarm automatically
when the fault has been corrected.

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.

HSPA CONFIG
Meaning
The alarm indicates that the High Peak Rate HSPA configuration
parameters (for DC 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 and HSUPA IC)
or when the cell is deleted/locked.
Alarm indication preventions can be altered with MML command AFC.

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 RNC RNW Object Browser.
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
RNC RNW Object Browser.
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.
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 RNC RNW
Object Browser.
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 with a command of the service terminal extension MRS (see Service
Terminal Essentials, Maintenance Manual) or from the document General
Error Messages of System, Supplementary References.

Possible reasons:
- There is a mismatch of the HS-DSCH channel configuration between
the controller and BTS.
- BTS runs out of capability due to, for example, a HW failure.
Actions to be taken:
1)
Check if there are any BTS end failures that are indicated with
76xx alarms and that could affect this feature (for example some
HW unit failure).
3)
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.

Possible reasons:
- There is a mismatch of the E-DCH channel configuration between
the controller and BTS.
- 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 the cell parameter WCEL - HSRACHEnabled in the controller
using the Element Manager. If this parameter value for the cell
is the same as in the BTS Site Configuration File, no actions
are needed in the controller.
If the cell parameter in the controller is not the same as
the one in the BTS Site Configuration File and the parameter
needs to be updated, use the Element Manager to take the
following actions to the cell that has failed to accept
the parameter sent:
- Lock the WCEL.
- Modify the WCEL - HSRACHEnabled parameter.
- Unlock the WCEL.
