Hi Stefan, check the BSC alarm by rxmfp command for the cell.27th July 2010 at 06:53 #41536Mogwadi PGuest
Can someone please help in solving the fault code:
SO CF 12A:57 and RF Performance in RBS 2202. We tried different methods to solve this but could not win. Your help is highly welcome.24th August 2010 at 11:36 #41537AMITGuest
IN ERICSSON BSC WHAT ARE COMMAND TO DIAPLAY CELL INFO SERVICE IN ANY BTS AREA14th October 2010 at 02:06 #41538SuhairiGuest
need details info about the fault codes class 2A 57.14th October 2010 at 07:21 #41539ATTOGuest
SO CF I2A:57
RX path imbalance
AO RX I2A:5 – RX path A imbalance
AO RX I2A:6 – RX path B imbalance
AO RX I2A:7 – RX path C imbalance
AO RX I2A:8 – RX path D imbalance
AO TX I1B:35 – RX path imbalance
SO CF RU:40 – Antenna
This fault occurs together with a pinpointed antenna, if the difference in signal strength between two antennas in the same antenna system exceeds the limits defined using the OMT function Define RX Path Imbalance Parameters. If the class 1 limit is exceeded, the related fault AO TX I1B:35 is also issued and the TX will be disabled.
The supervision of this fault is based on measurements over a long time duration, hence the fault does not cease as soon as the fault condition is corrected. The RX imbalance monitor must therefore be used to verify the correction of the fault condition.
When the fault condition has been corrected, reset the TRU to cause the fault to terminate immediately.
Observe, If the fault condition was not corrected, the fault will be reported again when at least the minimum number of samples has been collected. The minimum number of samples is defined by the Define RX Path Imbalance Parameters function in the OMT.
Follow the instructions below until the fault is corrected:
Check the defined RX path invariance limits using the Define RX Path Imbalance Parameters function in the OMT for the faulty antenna system.
Check the TX cables/feeders, cable connections inside and outside the cabinet and antennas, for example with Antenna System SWR tests. For information about how to perform a SWR test see Verifying Antenna Systems or Antenna System Tests in the CPI for the relevant RBS.
Reset the TRU

DECRIPTION FOR TF FAULT CODE:
Note: Only when TF mode is master or stand-alone. The synchronisation reference from the PCM network is faulty (for example too much jitter/wander) or missing. This is probably a transmission fault. If the fault occurs while TF is trying to synchronise, then the fault AO TF EC1:1 arises after 5 minutes. If the fault occurs while TF is synchronised, then TF goes into hold-over mode (that is stops using the reference) and after 5 minutes, the fault AO TF EC2:0 arises on TF. If the PCM reference has not come back within one hour (hold-over timeout), fault AO TF EC1:1 arises and TF becomes disabled. Follow the instructions below until the fault is corrected: Check the PCM line, the transmission equipment, and so on. Check the PCM quality with the BSC printout command DTQUP: DIP and the OMT monitor Phase difference error, PCM. Note: The preferred PCM reference can be set in the IDB, for example PCM A, PCM B or both.28th October 2010 at 17:46 #41541ABHISHEK SINGHGuest
DEAR ALL , PLZ GIVE ME THE REASON BY WHICH DB PARAMETER FAULT RAISE ON TRX. GIVE SOLT. FOR CORRECT THIS ALARM2nd November 2010 at 04:56 #41542kokilaGuest

i m new in the field of telecom.
i needs list of cammands which are neccesary for Ericsson bts.
like: hand over define cammands,half rate cammand,to decrease the power of sector etc22nd November 2010 at 13:39 #41544Chepete D.Guest
Can somebody help me with
48 Fault Code 33, Class 2A, Replacement Units 40(BTS internal)30th November 2010 at 11:47 #41545digant dadhichGuest
when we use cammand:
we will find many codes error like: R13B/A,R2A,R3D,R6E
WHAT IS MEANING OF ABOVE CODES N HOW CAN WE SHOUT OUT THESE PROBLEMS?
