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

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.

InstructionsThere may be disturbances in the signal path, or the timing of thenetwork does not work properly. Check these if the alarm does notdisappear after a few seconds. It should be noted in the case ofoccasional alarms that fading may sometimes occur, especially whenradio links are used along the signal path.
The alarm can also be caused by a faulty unit (the far-end or thealarming one) or a faulty repeater in the signal path. Check them, too.The internal loopbacks of the BIE and other transmission units canbe used to search the fault. The loops can be created andremoved from the Controls submenu of the service terminal.

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.
Supplementary information fields

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

7735 TRX TEST FAILED
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.
