3 7001 TRX/FU: CHECKSUM ERROR INPRIMARY CU-FU LINK
Meaning
The frame unit (FU) has detected a data transfer check sum error in the
data which comes in from the carrier unit (CU). This alarm concerns the
redundant or diversity data link between the CU and the FU, which goes
via the redundant or diversity FQHU or DFHU.
This alarm has two categories: non-fatal (no effect on service) and
fatal (an effect on service). This alarm is fatal in the following cases:
- The number of the data transfer check sum errors in the primary link
exceeds the specified limit and there is a fatal alarm in the
diversity/redundant link.
- The number of the data transfer check sum errors in the primary
link exceeds the specified limit and the diversity/redundant link
is not equipped.
The fatality limits can be found in document Digital BTS FUC
Monitoring Interface, B61 S60005CE (C3_FHI_A_ERR).

89 7151 BCF/MCLx: OVEN OSCILLATORFAILURE
Meaning
The oven oscillator of the master clock unit is alarming.
The temperature control of the oven oscillator may be faulty, or less
than 5 minutes have passed after the power-up and the operating
temperature of the master clock unit's oscillator is not reached.
In these cases, the OMU can not set the unit in any working mode.
The fatality of the alarm depends on whether a redundant master clock
unit (MCLx) is installed. If this alarm is active and the redundant
MCLx unit is not installed, the whole cell site is without
synchronization and timing, and this cell site is unable to transmit
any traffic.
MCLx
The master clock unit (MCLx) controls the synchronization and the
timing of the cell site. The clock signals are essential for the
operation of the cell site, and it is possible to double the master
clock unit in order to ensure the redundant control of the
synchronization.

7256 BCF/BIE: ALARM INDICATION SIGNAL (AIS) 2M RECEIVED
Instructions
The AIS signal indicates that something is wrong in the far end
and it must checked. Read the alarms of the far end equipment.
This alarm is caused by one of the following reasons:
- a loop to the equipment has been created in the far end;
- the equipment has been reset in the far end;
- the interface is not in use in the far end;
- some other limited fault in the far end unit.
The internal loopbacks of the BIE and other transmission units can
be used to search the fault location. The loops can be created and
removed from the Controls submenu of the service terminal.
Cancelling
Do not cancel the alarm. The system cancels the alarm automatically

Instructions
In the BTS, the use of this alarm is improbable, because normally
the multiframe (MF) is not in use. There is even no multiframe
setting in the present FW versions of the BIE.
The unit interface settings and the other alarms have to be
checked by means of the commands of the service terminal at
both ends of the PCM signal path. Check also that the FW
versions of BIE are allowed ones.
The multiframe alignment is considered lost when two received
successive multiframe alignment words have been erroneous, or
when only zeros are received from the time slot during one

Meaning
The BIE is not properly equipped.
The location of each tributary unit of the BIE (DX2M, SMBS, LK2M) has
been stored in the memory of the master unit (DB2M or SMHW). The master
unit has noticed that the actual configuration does not match with the
configuration in the memory. There should be another type of unit
at some location.
This alarm affects the provided services. The BIE is not working
properly, and the entire cell site may be blocked.
BIE
The base station interface equipment (BIE) is the 2 Mbit/s PCM
equipment of the BTS. It carries speech and data traffic, signalling

Instructions
Check that the BIE is equipped correctly (the actual configuration).
If it is, try to reinstall the BIE and check that the configuration
in the memory matches with the actual one. If reinstalling does not
work, replace the master unit (DB2M or SMHW). Then install the BIE
again and check that the actual configuration matches with the memory.
If these actions do not give the desired result, replace the tributary
units one by one, install the BIE and check the installation.
If the BIE was not correctly equipped to begin with, correct the
configuration and reinstall the BIE, if needed.
Every time a BIE unit has been replaced or a new unit installed, the
correct settings must be given to the new unit. In some cases the
installation command of the BIE equipment is also needed.

This is a fatal alarm.
TRX
The TRX has four main tasks. It is the radio interface of the GSM (DCS)
base station, it handles the signalling between the base station
controller and the mobile station and it relays all traffic between the
Abis interface and the radio interface. It also performs all baseband
operations for traffic data, for example, encryption, decryption,
coding, decoding and demodulation and combining the two branches in
the case of antenna diversity.

Meaning
BCF sends the e-cell adjustment request to all TRXs and waits for
ACK or NACK. The BCF waits for the response for 10 seconds.
After receiving ACK, the BCF continues normally by sending the
dynamic configuration to TRXs.
If NACK is received or timer is expired, the configuration of that
TRX is stopped and this alarm is sent to the BSC and MMI after
the configuration.
E-CELL
Dynamic cell radius extension. Based on a solution with one BCCH
and two TRXs.
Different TRXs serve normal area and extended area. The TRX which
serves the normal area is normally configured with BCCH/SDCCH and TCHs.
The timing of receiver of the TRX which serves the extended area (E-TRX)
has been delayed so that it can serve an area beyond 35 kilometres.
BCF
The Base Control Function (BCF) unit is responsible for the operation
and maintenance of the BTS. The main functions of the BCF are:
loading of the BTS operational file packets from the BSC to the BTS,
initialising the BTS, continuous supervision of the BTS equipment,
reporting faults to the BSC and testing and operating functions.
The BCF is also the source of main clock pulses of the BTS.

3307704 PCM FAILURE
Meaning
The alarm concerns a PCM containing BCF links.
The radio network objects whose LAPD links are part of this
particular PCM are not functioning. Significance of this alarm
depends on the number and nature of LAPD links connected to this PCM.
Supplementary information fields
Instructions
Alarm 7704 is BCF-specific (the bcf_id is provided).
It is used by the RNW recovery part of the BSS system.
This alarm (and cancel) will cause radio network recovery
actions concerning objects connected through the faulty
PCM (ET). Alarm 7704 does not occur alone. There are always
some other alarms active at the same time.
FOR EXAMPLE:
PCM cable is disconnected from the ET. Alarms 7767, 2900, 2915,
7706 and 7704 are generated.
Alarm 7704 causes state change of corresponding TRX(s) to
BL-RSL and state change of corresponding LAPD links to
UA-AD RN RECOV.
In order to find out the cause or effects of this alarm,
check the following:
1. Check corresponding (ET<->PCM) active alarms (for
example 2915,2900)?
a) MML command AHO
b) See instructions for those alarms
DN9813099Issue 20-4 en
# Nokia Siemens Networks 703 (1087)

2. For further information observe the effects (RNW) of alarm 7704
with the MML commands
a) EEI
- which RNW objects are not usable?
b) EOL
- which alarms are directed at the specific BCF?
c) DTI
- what are the working states of OMUSIG and TRXSIG?

General Error Messages of System
Instructions
Check the value of the supplementary information field 1 (error type).
Error type values:
01H or 04H:
If the value of field 2 (interrupted task) is 15H or 17H,
cancel the alarm and make the database changes to the cell manually.
Check the adjacencies of the cell and update the data if needed. (MML
commands EOR, EQA, EQE, EAM, EAO, ERM, ERY).
If the value of field 2 is not 15H or 17H, cancel the alarm. Then
change the object in question to LOCKED state and then back to
UNLOCKED. The call control software receives thus the updated data.
(MML commands EOR, ERS, EQS).
02H:
If the value of field 3 (conflicting family) is 1B3H, cancel the
alarm. Then change the parameter LEV of the TRX in question to a
different value and then back to the original value. TRX parameters
are thus updated to call control. (MML commands EOR, ERM).
744 (1087) # Nokia Siemens Networks DN9813099Issue 20-4 en
Base Station Alarms (7000-7900)
If the value of the field 3 (conflicting family) is 434H, change
GPRS from enabled to disabled and back to enabled. If this does
not help, lock and unlock the BTS. Check also the state of
the PCU plug-in unit.
If the value of field 3 is not 1B3H or 434H, delete the TRX
in question and then re-create it with the correct parameters.
The call control software thus receives the correct data.
(MML commands ERD, ERC).
03H:
Set the BTS in question to LOCKED state. Set the HOPP parameter
value of the BTS to N (No Hopping) and then back to the original
value. The hopping parameters are thus updated to call control.
Finally, set the BTS to UNLOCKED state. (MML commands EQS, EQE).
If the alarm has not been cancelled yet, cancel the alarm
with the MML command EOR.
Cancelling
Cancel the alarm with an MML command after correcting the fault as
presented in the INSTRUCTIONS. See Alarm Administration.

3507725 TRAFFIC CHANNEL ACTIVATIONFAILURE
Meaning
The system has blocked the radio time slot because the call
control has failed a number of times in the activation of
a traffic channel.
Supplementary information fields
1 Type of the channel whose TCH activation failed
The channel type can be "TCH" , "SDCCH" or "Packet Data TCH".
The number value "0" indicates "TCH", "1" indicates "SDCCH"
and "2" indicates "PDTCH" (Packet Data Traffic TCH).
Instructions
if the failure type is "PDTCH", the alarm is cancelled automatically
by the system, when no more failure indications are observed
if the channel type is "TCH" or "SDCCH", cancel the alarm with the MML
command EOR. Deblock the radio time slot by first aligning the TRX
in question with the command ERS and then removing the alignment
of the TRX
Cancelling
If the channel type is "TCH" or "SDCCH", cancel the alarm with a command
before taking the steps described in the INSTRUCTIONS, if the alarm has
not been cancelled before. See instructions on base transceiver station

Base Station Alarms (7000-7900)
3517726 CELL IN MINIMUMCONFIGURATION
Meaning
The cell has been set to the minimum configuration due to
a failure in clock setting or clock synchronisation. Only the
BCCH-TRX is functioning.
This means that the number of working traffic channels in the cell has
decreased because only one TRX is functioning and others are in
BL-CLK state.
This is the result of the fact that several TRXs cannot work in a
non-synchronised mode in the same cell and so just one TRX is left
to WO state.
Synchronised handovers may be unsuccessful if cell is in minimum
configuration because TRXs are commanded to internal clock mode.
BTS_ID in the alarm is the BTS which has the BCCH timeslot.
Supplementary information fields
Instructions
1. Check alarms on clock synchronisation that are active in the
cell.
2. Before correcting the fault, set the BCF into LOCKED state with
the MML command EFS.
3. Correct the fault according to the instructions of the alarms
on clock synchronisation that are currently active in the cell.

7726 CELL IN MINIMUM CONFIGURATION
4. After correcting the fault, set the BCF into UNLOCKED state with
the MML command EFS. This resets the clocks. NOTE! All calls in the
cell are released.
Cancelling
Do not cancel the alarm. The system cancels the alarm automatically
when the BCF or BTS is set to LOCKED state.

3527727 TRAFFIC CHANNEL NUMBERDECREASED
Meaning
Some traffic channels have been lost in the configuration because of a
TRX or TCH swap made by the radio network recovery. The loss is possible
in the following situations:
The faulty BCCH-TRX does not support half rate channels and the BCCH
functionality is swapped to a TRX that has half rate channels in
its configuration. In this case, the number of half rate channels may
decrease.
The traffic channels transferred to the faulty BCCH-TRX have to be
classified as not_in_use because the subslots for sign
parameter of the faulty BCCH-TRX indicates that the time slots
in question have no Abis allocation.
If the BCSU resources run out during the TRX recovery of the TRX or TCH
swap, the traffic channels are also changed to not_in_use channels. The
channel type is changed by the system from CH7 downwards.
The number of channels is observed for each BTS separately.
Supplementary information fields
1 The number of TCHH channels that were lost in the cell
configuration
2 The number of TCHD channels that were lost in the cell
configuration
3 The number of TCHF channels that were lost in the cell
configuration

Instructions
Find out why the faulty TRX is out of use by checking other alarms
affecting the TRX in question, and act according to their
instructions.
When the TRX is in working order again, return the channel
configuration back to the original. See instructions on radio network
administration.
Cancelling
Cancel the alarm with the MML command EOR after taking the steps
described in the Instructions.

3537728 OBJECT OUT OF USE BECAUSEOF ERROR IN BTS INTERNALDIAGNOSTICS
Meaning
Fault recovery has received a diagnostic block request from the BTS.
If the objects that the request applies to were in the WO state, fault
recovery has blocked them.
The BTS has not stopped internal runtime diagnostics automatically.
You can check the operational state of the object with the MML command
EEI. The operational state of the object under runtime diagnostics
is BL-DGN. Alarm is set when the operational state of the object is
BL-DGN. When the object is TRX, the operational state can also be
BL-RSL.
Supplementary information fields
Instructions
Lock and unlock the object with the following MML command: EFS for the
BCF, EQS for the BTS, or ERS for the TRX.
If the object stays blocked, it is faulty and other alarms specify
the fault.

3547729 RADIO NETWORK RECOVERYFAILED
Meaning
The BSC radio network fault recovery failed. The cause of the failure
is one of the following:
- reading the radio network configuration data failed
- the BCF-specific recovery buffer in the alarm system is full
- re-sending a fault has been attempted the maximum number of times
- the recovery system sent a DX error code in its acknowledgement
- recovery was interrupted because of a system restart.
The result may be a cell which does not transmit traffic because
radio network recovery has not received the fault, or a cell whose
capacity is out of use although it is not faulty, or a recovery
action which could not be terminated.
Supplementary information fields
1 PCM identifier
2 DCS identifier as a hexadecimal
3 number of the recovery action being processed
4 identifier of the alarm system's filtering buffer
5 general error message of the system. See General Error Messages of
System for error code explanations.
Instructions
1. Check the supplementary information field 4 (buffer id). If the
value is FF, go to step 5. If the value is not FF, perform steps 2-4.
DN9813099Issue 20-4 en
# Nokia Siemens Networks 755 (1087)
7729 RADIO NETWORK RECOVERY FAILED
2. Use the MML command EOL to check active alarms. Use the MML command
EOH to check the state of the alarm object (BCF) in the alarm history.
Check the state in the latest alarm directed to the BCF in question,
excluding this alarm.
3. Use the MML command EEI to check object states in the radio network
database.
The object state is wrong in the database, if
- alarm object state is DISABLED but WO in the database or if
- the object has no active alarms but its state is BL in the database.
4. Use the MML command EFS to lock the object which is in the wrong state
in the database and then unlock it with the same command. This updates
the correct object state in the radio network database.
5. Examine the alarm printout to find out the alarm object. If the object
is a radio network database object, perform step 6. If the object is
partly unknown (bcf id known), perform steps 7-8.
6. Lock and then unlock the alarm object. Use the MML command EFS for a
BCF, EQS for a BTS and ERS for a TRX.
7. Use the MML command EEI to check if the object has been created. If it
has not, create it. See instructions on BSS Integration
8. If the TRX id is 255 and the BTS type is Nokia Talk-family or Nokia
PrimeSite, check the logical IDs according to instructions in
BTS documentation.
Cancelling
Cancel the alarm with the MML command EOR after correcting the fault
as presented in the INSTRUCTIONS.

and all TRXs do not have EDGE HW and they have been added to DAP in the BTS,
then the following conditions must also be taken into account to make sure that
the TRX recovery works correctly in the EGPRS or CS3&CS4 enabled BTS:
- If a BCCH TRX is EDGE-capable, it has been added to EDAP, and it has the GTRX
parameter set to Y, all EDGE-capable unlocked TRXs that have GTRX set
to Y should be added to DAP and marked with the preferred BCCH mark
(PREF=Y).
- If a BCCH TRX is non-EDGE-capable and has the parameter GTRX set to
N, all the non-EDGE-capable unlocked TRXs that have GTRX set to N should
be marked with the preferred BCCH mark (PREF=Y).
1. Check whether the TRXs in the BTS have been configured correctly, that
is, whether the recommendation above has been followed.
2. a) If the configuration of the TRXs is not in order in the BTS,
1#. lock the BTS (EQS),
2#. lock the required TRX(s) (ERS),
3#. re-configure the TRX(s) (EQM),
4#. unlock the TRX(s) (ERS),
5#. unlock the BTS (EQS).

1. Check the physical Abis transmission path and the cross-connection
equipment.
2. If required, reconfigure the TRX. See instructions on Radio Network
Administration, Primary Rate Access D-Channel Data Handling
and Primary Rate Access D-Channel State Handling.
2. The Abis Loop Test is not possible if baseband hopping is used.
Use the MML command EQO to see whether baseband hopping is used
and, if necessary, turn it off with the MML command EQE.
3. Execute the Abis Loop test to the whole TRX with the MML command UBK.
Cancelling
Do not cancel the alarm. The system cancels the alarm when the Abis
loop test has been executed successfully to the TRX or the RTSL that
has generated the alarm.
If the alarm is set for the TRX, the RTSL specific cancel cannot cancel
the TRX specific alarm. The TRX specific alarm can be cancelled only
when testing is requested to whole the TRX (every RTSLs are tested in
the same test request).
The test succeeds when the threshold values for the test result
parameters (BER/FER) are not exceeded. The user cannot change the
threshold parameters.

Instructions
Find out the reason for the loss of BTS traffic capacity and bring
the BTS back to use. This may reqire for example locking, resetting and
unlocking the BTS or BCF object. Note that these actions cause both CS
and PS traffic to drop within the entity that has been reset. To
restore the GPRS service in a BTS, disabling and enabling GPRS (GENA=N,
GENA=Y) in the alarmed BTS may be sufficient.
Check that the parameters in connection with the alarm are reasonable.
Too short a supervision period may cause false alarms.
The MML command EEO outputs the radio network supervision parameter
values, and the EEN command modifies the parameter values.

The transmission unit (TRU) or a redundant TRU 2 does not respond to
the poll command from the BCFA unit on the Q1 bus. Connection to the
TRU is broken or unit is not inserted.
This alarm can affect the provided service of the BTS or of the
transmission network. The current status of the transmission unit is
not known and obviously the commands to the TRU do not reach the TRU.
Transmission unit (TRU) is the PCM equipment of the BTS.It connects
the BTS to the transmission network. The TRU or its redundant unit
carries all speech, data and signalling traffic of the BTS towards
the BSC or other BTSs.

4797946 DIVERSITY BRANCH LNA OUT OFORDER IN ANTENNA FILTER UNIT
Meaning
Both amplifier branches are broken in the low noise amplifier (LNA)
of the diversity receiving path in the AFE. The diversity RX does not
work in those TRXs which are connected to the diversity receiving
path of this AFE unit.In a configuration of the one AFE per sector
the whole BTS sector is without diversity path receiving but in a
configuration of the two AFE unit per sector only part of sector
is without diversity path receiving.
AFE
Transmitting
The antenna filter unit (AFE) combines one or two transmitters to
one single transmitting antenna. The AFE also filters transmitter
signals to reach better signal quality.
Receiving
The antenna filter unit (AFE) filters and amplifies the signal
received from the receiving antenna. The amplified output signals
are connected to the receivers of the BTS. Each AFE contains two
low noise amplifiers (LNA), one for the main and one for diversity
receiving path. One LNA contains two different amplifier branches.
The LNA is out of order if both of those amplifier branches are
faulty.

5027970 FAULT IN MAIN BRANCH LNA OFRECEIVER MULTICOUPLER
Meaning
One of the parallel amplifiers is broken in the low noise amplifier
(LNA) of the main receiving path in the RMU. The RX performance is
degraded in the whole BTS sector. The BTS RF receiving capability
is reduced.
RMU
The receiver multicoupler unit (RMU) filters and amplifies the signal
received from the antenna. Four amplified output signals are connected
to the base station receivers. Additionally, there is one output to the
RMX (receiver multicoupler extension unit) that is used in large
configurations (more than 4 TRX in one cell). All outputs are doubled
for diversity purposes.
Each RMU contains two low noise amplifiers (LNA), one for the main
and one for diversity receiving path. One LNA contains two parallel
amplifier branches. The LNA is out of order if both of those amplifier
branches are faulty.
