3 7001 TRX/FU: CHECKSUM ERROR IN PRIMARY CU-FU LINKMeaning

The frame unit (FU) has detected a data transfer check sum error in thedata which comes in from the carrier unit (CU). This alarm concerns theredundant or diversity data link between the CU and the FU, which goesvia the redundant or diversity FQHU or DFHU.

This alarm has two categories: non-fatal (no effect on service) andfatal (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 FUCMonitoring Interface, B61 S60005CE (C3_FHI_A_ERR).

FU

The frame unit includes all control and baseband functionsrelated to each speech connection. The frame unit consistsof three digital boards: a frame unit controller and twoidentical digital signal processing units.

FUCx

The frame unit controller board, FUCx, handles the signallingbetween the base station controller and the mobile station.The FUCx relays all traffic data between the BIE and the DSPxsand between the DSPxs and the carrier unit.

DSPx

The digital signalling processing unit, DSPx, performs allbaseband operations for traffic data, for example, encryption,decryption, coding, decoding and demodulation and combining ofRF signals in the case of antenna diversity.

CU

The carrier unit (CU) is located in the radio interface inthe BTS. The main function of the CU is to convert the basebandsignal to the radio frequency signal and vice versa. The CU

50 DN9813099Issue 23-4

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

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 frequencyhopping. The FQHU is located in the fast serial link betweenthe FU and the CU. The fast serial link carries out data transmissionbetween the FU and the CU. The FQHU connects the FUs to the CUsaccording to the frequency hopping law by switching the seriallinks.

DFHU

The dummy frequency hopping unit (DFHU) connects the FUs and theCUs transparently together, that is, the FU1 is connected to theCU1, and so on.

The speech and data connection to the specified GSM time slot is faultyin the base station interface. The frame unit controller (FUC) tries torecover the fault situation by reinitializing the time-slot-specificpart of the interface. If the reinitialization does not succeed toclear the fault situation, this alarm is activated.

This alarm affects the provided service. If this GSM time slot is usedfor mobile calls, the calls do not succeed when this alarm is active.

BSI

The base station interface (BSI) is the interface connecting the frameunit controller (FUC) and the base station interface equipment (BIE).All telecommunications traffic to or from the TRX goes through thebase station interface.




Instructions1. Check the operation of the base station interface equipment (BIE).2. If the BIE is in order, change the FUCx.3. If the alarm does not disappear, change one DSPx.4. If this does not help, change the other DSPx.5. If the alarm is still active, check the transmission line to or from the base station controller (BSC).

7100 BCF/RFTE: HIGH SIGNAL LEVEL (>-70 DBM) IN THE RFTE OUTPUT

54 7100 BCF/RFTE: HIGH SIGNAL LEVEL (>-70 DBM) IN THE RFTE OUTPUTMeaning

The signal detecting line of the RFTE has measured a higher signallevel than -70 dBm in the RFTE output. The time slots which are notused for the RFTE tests are supervised.

This alarm affects the provided service because normally it indicatesthat there is an interfering leaking signal from the RFTE to the BTSreceiver path.

RFTE

The radio frequency test equipment (RFTE) is used to test the operationof the BTS. The possible tests are radio loop and receiver antenna(RAX) tests. These tests can be started locally at the cell site orremotely from the OMC/BSC. Because the test loops are made inside theBTS, the RFTE's main task is to convert the test signal from the transmitband to the receive band.




InstructionsCheck external disturbances. If there are none, change the RFTE.

7726 CELL IN MINIMUM CONFIGURATION

377 7726 CELL IN MINIMUM CONFIGURATIONMeaning

The cell has been set to the minimum configuration due toa failure in clock setting or clock synchronisation. Only theBCCH-TRX is functioning.

This means that the number of working traffic channels in the cell hasdecreased because only one TRX is functioning and others are inBL-CLK state.

This is the result of the fact that several TRXs cannot work in anon-synchronised mode in the same cell and so just one TRX is leftto WO state.

Synchronised handovers may be unsuccessful if cell is in minimumconfiguration because TRXs are commanded to internal clock mode.

BTS_ID in the alarm is the BTS which has the BCCH timeslot.


Instructions1. Check alarms on clock synchronisation that are active in thecell.2. Before correcting the fault, set the BCF into LOCKED state withthe MML command EFS.3. Correct the fault according to the instructions of the alarmson clock synchronisation that are currently active in the cell.4.

378 7727 TRAFFIC CHANNEL NUMBER DECREASEDMeaning

Some traffic channels have been lost in the configuration because of aTRX or TCH swap made by the radio network recovery. The loss is possiblein the following situations:

The faulty control channel (BCCH, SDCCH, ERACH) TRX does not supporthalf rate channels and the control channel functionality is swapped toa 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 haveto be classified as NOTUSED, because the subslots for the sign parameterof the faulty control channel TRX indicate that the time slots inquestion have no Abis allocation.

If the BCSU resources run out during the TRX recovery of the TRX or TCHswap, the traffic channels are also changed to NOTUSED channels. Thesystem changes the channel type from CH7 downwards.

The number of channels is observed for each BTS separately.

Supplementary information fields1 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

Instructions1. To avoid this alarm being triggered unnecessarily, the PWRx threshold values should be permanently set as follows (valid for all TX combining options):

BTS type TX power threshold Recommended value (with PMAX=0) MetroSite PWRM +26 dBm HP MetroSite PWRH +33 dBm UltraSite EDGE PWRU +43 dBm Flexi EDGE PWRE +41 dBm

These values leave room for the expected (BTS type specific) tolerances. Each threshold value applies to all similar BTS types under the same BSC. The current PWRx thresholds can be checked with MML command as follows: ZUCV:TRP,CURRENT; and adjusted with: ZUCV:TRP,MODIFY:PWRx=<new value>;

Note that the recommended values are valid for PMAX=0 only. If a lower PMAX value is used (even in one BTS (sector) on the same BSC), the PWRx should be lowered accordingly. For instance, if PMAX=2 is used even in one Flexi-EDGE BTS under testing, the PWRE on that BSC should be set to +39 dBm (that is, 2 dB lower).

When the test is run by using a local or remote BTS Manager, only the BTS SW internal thresholds are used. This way, unnecessary failures because of the above-mentioned BSC (S12 or earlier) threshold issue cannot be caused. Nokia Siemens Networks recommends that you run the TRX test again with the BTS Manager before making a decision to replace the TRX unit.

2. If the previous action fails to remove the fault, contact your local Nokia Siemens Networks representative.

CancellingDo not cancel the alarm. The system cancels the alarm when the TRXtest (either single or scheduled) for the MetroSite or UltraSitebase station is successful in the TRX and the diversity thatgenerated the alarm.

The test succeeds when the threshold values set for the resultparameters are not exceeded.

416 7787 SYNCHRONISATION IS MISSINGMeaning

The synchronisation of the chain or a BCF in the chain is lost.The synchronisation status of the chain or the BCF is set tounsynchronised by the system.

In a synchronised BSS the LMU equipment is used as a synchronisationsource for the BCFs in the chain. If the synchronisation of the clockchain 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 alarmaffects only to the slave BCF. This alarm may affect the provided services.

Supplementary information fields1 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.

InstructionsThis alarm is usually a result of a fault situation in the BTSdetected by the BTS or BSC. Use the MML command EOL to list otheralarms affecting the BCF in the chain and act according to theirinstructions.

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 allBCFs or to some BCF(s) in the chain. The synchronisation status ofthe 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 tosynchronised mode.

If the system does not cancel this alarm, lock and unlock the faultyobject (BCF) with the EFS MML command. This causesa restart of the object. If the object to be unlocked is a master clockBCF, then the unlock causes that all unlocked BCFs in the chain willbe restarted. Then the system cancels all alarms, which affect theunit, and if necessary, sets them again. In such a case, correct thefault according to the instructions in the active alarms whichaffect to the unit.
