2 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

DN9813099Issue 22-0 en07/03/2008


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.

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 base band

operations for traffic data e.g. encryption/decryption,

coding/decoding, demodulation and combining of RF signals in the case

of antenna diversity.

used for the RFTE tests are supervised.

This alarm affects the provided service because normally it indicates

that there is an interfering leaking signal from the RFTE to the BTS

receiver path.

RFTE

The radio frequency test equipment (RFTE) is used to test the operation

of the BTS. The possible tests are radio loop and receiver antenna

(RAX) tests. These tests can be started locally at the cell site or

remotely from the OMC/BSC. Because the test loops are made inside the

BTS, the RFTE's main task is to convert the test signal from the transmit

band to the receive band.

Meaning

The alarm is sent to the BSC when the FU, CU ,TRX or BTS object is

locally blocked by a BTS MMI command. Typically, units are blocked

when faulty units are changed at the site. When the local block

command is given, the following operations take place:

- The BTS sends a cancel message to those blocked unit alarms

which have been reported to the BSC before the block command

was given.

- The BTS sends the alarms of the blocking function to the BSC.

- The BTS does not send alarms of the blocked unit to the BSC

any longer.

This alarm can affect the provided service.

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.

3287704 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.


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

3497726 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.

half rate channels and the control channel functionality is swapped to

a TRX that has half rate or dual rate channels in its configuration.

In this case, the number of traffic channels may decrease.

The traffic channels transferred to the faulty control channel TRX have

to be classified as NOTUSED, because the subslots for the sign parameter

of the faulty control channel TRX indicate 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 NOTUSED channels. The

system changes the channel type 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

7727 TRAFFIC CHANNEL NUMBER DECREASED

5 The number of LRTCH 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. For more information, see

instructions on radio network administration.

Cancelling

The system can cancel this alarm automatically when the original TCH

count is returned. An example of this kind of situation is when the

TRX fault is cancelled and the BCCH TRX is swapped back to original

BCCH TRX.

This alarm is cancelled when the BTS's configuration is changed.

The creation/deletion of some TRX or RTSL type modification cancels

this alarm. The activation of a new RNW configuration (including

TRX creation/deletion or RTSL type modification) via plan also cancels

this alarm.

This alarm can be cancelled with the MML command EOR after taking the

steps described in the Instructions. For more information, see Base

Transceiver Station Alarms Handling, Command Reference Manual.

3517728 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.

3527729 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.

DN9813099Issue 22-0 en07/03/2008


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.

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),

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:

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.

Parameters, with their default values, affecting the alarm:

ZEEN:MAXHTT= maximum mean holding time for TCH (120 min)

MAXHTS= maximum mean holding time for SDCCH (30 min)

PRDMHT= length of TCH supervision measurement (240 min)

PRDMHS= length of SDCCH supervision measurement (60 min)

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.

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.

DN9813099Issue 22-0 en07/03/2008



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

This alarm does not affect normal operation.

MMI

The man-machine interface (MMI) is a software used in the PC.

It can be connected to the BCF and it enables doing several

local operations to the BCF.

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 also controls the frequency hopping operations of the

BTS. The connection of the BTS's user interface is at the front
