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).

FU

The frame unit includes all control and baseband functions

related to each speech connection. The frame unit consists

of three digital boards: a frame unit controller and two

identical digital signal processing units.

FUCx

The frame unit controller board, FUCx, handles the signalling

between the base station controller and the mobile station.

The FUCx relays all traffic data between the BIE and the DSPxs

and between the DSPxs and the carrier unit.

DSPx

The digital signalling processing unit, DSPx, performs all

baseband operations for traffic data, for example, encryption,

decryption, coding, decoding and demodulation and combining of



7001 TRX/FU: CHECKSUM ERROR IN PRIMARY CU-FU LINK

RF signals in the case of antenna diversity.

CU

The carrier unit (CU) is located in the radio interface in

the BTS. The main function of the CU is to convert the baseband

signal to the radio frequency signal and vice versa. The CU

consists of a transmitter (TXUx) and one or two receivers (RXUAs)

depending on whether diversity is used.

FQHU

The frequency hopping unit (FQHU) performs baseband frequency

hopping. The FQHU is located in the fast serial link between

the FU and the CU. The fast serial link carries out data transmission

between the FU and the CU. The FQHU connects the FUs to the CUs

according to the frequency hopping law by switching the serial

links.

DFHU

The dummy frequency hopping unit (DFHU) connects the FUs and the

CUs transparently together, that is, the FU1 is connected to the

CU1, and so on.

7553 MEMORY FAULT IN DBUS INTERFACE OF TRX

Cancelling






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.

Then check the value of the supplementary information

field 2 (interrupted task).

Interrupted task values:

03H, 04H or 17H:

Check radio network parameters of the cell. Radio network recovery

function may have changed some TRX's parameters before failure but

some TRX may have old parameters. Delete the TRX and then re-create

it with the correct parameters. After that change the BTS first to

LOCKED state and then to UNLOCKED state to ensure parameters updating

to BTS site.

If interrupted task is not any of the values above then check the

value of the supplementary information field 1 (error type).

Error type values:

01H or 03H:

Change the TRX first to LOCKED state and then to UNLOCKED state.

The radio network database should now be updated correctly. (MML

command ERS). If the update still fails, delete and

re-create the BTS.

02H:

Delete the TRX and then re-create it with the correct parameters. The

radio network database should now be updated correctly. (MML commands

ERD, ERC). If the update still fails, delete and re-create the BTS.



04H:

Make the necessary radio network parameter changes manually. (MML

commands EQS, ERS, EQE, EQP, EAM, ERM, ERY).

3497724 CONFLICT BETWEEN BSS RADIONETWORK DATABASE AND CALLCONTROL

Meaning

The fault recovery or configuration management system of the BSS

radio network has updated the BSS Radio Network Configuration Database

(BSDATA) according to the changes in background parameters or the

fault situation in the radio network.

However, the update of the operational state of the radio

network or the update of the reconfiguration of the radio

network to the BSC's call control program block failed.

Due to the failed update, there is a conflict in radio network data

between the radio network database and the call

control program. Because of this, calls may be blocked in

the cell in question.

If changes in background parameters are involved, also the incoming

and outgoing handovers may fail.


1 type of the error

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).



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.



7724 CONFLICT BETWEEN BSS RADIO NETWORK DATABASEAND CALL CONTROL



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.


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

alarms handling.



7725 TRAFFIC CHANNEL ACTIVATION FAILURE



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.


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


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.


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



7727 TRAFFIC CHANNEL NUMBER DECREASED

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


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.


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.



7728 OBJECT OUT OF USE BECAUSE OF ERROR IN BTSINTERNAL DIAGNOSTICS

Cancelling





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.


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


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.



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

Do not cancel the alarm. The system cancels the alarm when the TRX

test (either single or scheduled) for the Nokia Metrosite or

Nokia UltraSite base station is successful in the TRX and

the diversity that generated the alarm.

The test succeeds when the threshold values set for the result

parameters are not exceeded.




Meaning

The Abis Loop test has failed. The quality of the transmission path has

been decreased substantially. The Abis transmission is probably faulty.

The alarm is set if even one of the tested subtimeslots exceeds the

threshold value.


1 state of the Abis transmission concerning to radio timeslot 0

00 means that RTSL was tested and the result of testing is 'FAILED'

FF means that the field is not significant

























Instructions

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.

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.

Parameters, with their default values, affecting the alarm:




ZEEN: SMBNT= supervision start time (08-00)

EMBNT= supervision end time (18-00)

PRDBNT= length of supervision period (120 min)

Cancelling

The system cancels the alarm once it detects the BTS traffic capacity

has been restored, that is, when a normal channel release of the

type that was faulty occurs or, in case of a GPRS related cause, when

a successful TBF release occurs in the BTS. Note that if the alarm was

originally raised with both CS and PS reasons (16..19), and the

service occures either to PS or to CS domain, the alarm may remain for

the other domain.

The user can also cancel the alarm with the EOR command after

correcting the fault as presented in the INSTRUCTIONS.

All supplementary alarm fields are set to zero irrespective of wheter

the alarm is cancelled manually or by the system.

check the values in field 5-8 for more information.

See instructions on radio network testing.

If the DX error code in field 4 is other than the above-mentioned,

see General Error Messages of System.

Cancelling

Do not cancel the alarm. The system cancels the alarm when an

originating call through the base station succeeds.




Meaning

The same radio network alarm has changed its alarm state (start/cancel)

20 times consecutively, always during informing or cancelling delay,

and has thus been filtered by the alarm system. The same radio network

object is the object of both this alarm and the beating alarm that

caused this alarm.


1 the alarm number of the beating BTS alarm

2-15 if the beating alarm has any additional information, it is

indicated here. Additional information is cut after 14

bytes and it is represented in hexadecimal format.

Instructions

Take E00 service terminal extension into use in the working MCMU

with the following command:

ZLE:<char>,E00_BXSX

Note that you need to check which MCMU is in the working state with the

command ZUSI:COMP;

Use the E00 service terminal extension command S to find out whether

the channel seizure that caused the alarm is a real call or an

unreleased channel.

Give the following command to the working MCMU unit:

Z<char>S:<BTS_id>,0,B,20;



7741 MEAN HOLDING TIME ABOVE DEFINED THRESHOLD

Note that the parameter BTS_ID is given in hexadecimal format.

RRMPRB states are on CH STA column:

0=DISC 10=IDLE 20=BUSY FF=CBCH

ABIPRB states are on the last column of the output row:

0 = blocked

1 = free

2 = signalling

3 = conversation

4 = not in use

5 = CBCH

Compare the channel state in RRM and ABI to determine whether

the channel is unused but unreleased.

In the case of an unreleased channel, if it is a traffic channel,

restore the channel by first locking it out of use and then unlocking

it (TCH lock/unlock). Use the MML command ERS and give the TRX and

the channel as parameters.

ZERS:<BTS>,<TRX>,<CH>:L; lock

ZERS:<BTS>,<TRX>,<CH>:U; unlock

If it is a signalling channel, restore the channel by locking and then

unlocking the whole TRX (TRX lock/unlock). Use the MML command ERS

and give the TRX as a parameter.

Check that the parameters affecting the alarm are reasonable.

MML command EEO outputs the radio network supervision parameter values,

EEN command modifies the parameter values.

Cancelling

If the alarm does not require user actions, you can cancel it with

the MML command EOR.

The system cancels the alarm when you lock and unlock the object in

question, or, if the alarm requires no user actions, the system cancels

the alarm at the end of the measurement period during which the channel

that caused the alarm is allocated/ released normally.




Meaning

The BCF has been set in maintenance mode. Alarm handling in the object

is limited.


Instructions

Restart the BCF when you set the maintenance parameters back to their

original states or as soon as possible afterwards, as alarm handling

is limited during maintenance. The BCF restart is performed

automatically when the BCF is changed from maintenance mode to

normal mode, if the user has entered the parameter concerning restart.

Meaning

The synchronisation of the chain or a BCF in the chain is lost.

The synchronisation status of the chain or the BCF is set to

unsynchronised by the system.

In a synchronised BSS the LMU equipment is used as a synchronisation

source for the BCFs in the chain. If the synchronisation of the clock

chain is lost, the alarm affects the master clock BCF of the chain.

If the synchronisation of a slave BCF in the chain is lost, then the alarm

affects only to the slave BCF. This alarm may affect the provided services.


1 identifies the BCF in the chain, the synchronisation of which

is lost. If BCF_ID is same as the id of the master clock of

the chain, the synchronisation of the all BCFs in the chain

is lost.

2 identifies the first BCF in the chain after the LMU. The chain

is identified by the id of the master clock BCF.

Instructions

This alarm is usually a result of a fault situation in the BTS

detected by the BTS or BSC. Use the MML command EOL to list other

alarms affecting the BCF in the chain and act according to their

instructions.

Check that the system cancels the alarms (including this alarm)

which affect the faulty unit.

The alarm indicates that the LMU cannot feed the clock signal to all

BCFs or to some BCF(s) in the chain. The synchronisation status of

the BCF(s) in the chain is not lmu synchronised any more.




Check that the system cancels the alarms (including this alarm),

which affects to the faulty unit. This returns the synch status to

synchronised mode.

If the system does not cancel this alarm, lock and unlock the faulty

object (BCF) with the EFS MML command. This causes

a restart of the object. If the object to be unlocked is a master clock

BCF, then the unlock causes that all unlocked BCFs in the chain will

be restarted. Then the system cancels all alarms, which affect the

unit, and if necessary, sets them again. In such a case, correct the

fault according to the instructions in the active alarms which

affect to the unit.

When the BCF is restarted the system cancels all alarms which affect

the BCF and, if necessary, sets them again.

Cancelling

Do not cancel the alarm. The system cancels the alarm automatically, when

5067974 BOOSTER TEMPERATURE TOOHIGH

Meaning

The temperature of the booster unit is too high.

Booster

The basic principle in the booster configuration is to locate a high

power amplifier in the BTS to boost downlink transmission.

In practice, the booster will replace the 2nd TRX in the BTS cabinet.

The booster configurations can be used with existing Nokia Talk-family

base stations in GSM 900, GSM 1800 and GSM 1900 networks in all cases

where cable loss compensation is needed.

When the alarm is activated, the BTS stops the TX transmission

of the TRX connected to the booster until the fault has been

corrected.

Meaning

The radio relay unit (RR) or some other transmission equipment(TE)

does not response to the poll command from the BCFA unit on the Q1 bus.

The connection to the RR/TE is broken or the unit is not inserted.

This alarm can affect the provided service of the BTS or transmission

network. The current status of the tranmission unit is not known and

obviously the commands to the RR do not reach unit.

RR

The radio relay (RR) is an 18 - 38 GHz micro wave radio unit. RR units

are used, as a part of the transmission network, to carry GSM speech,

data, and signalling in transmission network between BTS and BSC

network elements.

TE

The transmission equipment is a unspecified transmission device

which is connected to the base station via Q1 bus.
