Hi May Uc means uncombined mode. DRU-E has chip in the backplane you have to switch that when using combined or uncombined mode

PLEASE I NEED SOMEONE TO TELL ME IF THERE IS ANY MEANS TO REPAIR A FAULTY
DRU

[Tom]

I am working on Ericsson 2206 v2 850 gsm cabinet. For the B secotr I am getting the following fault in my RBS logs: MO: TX, Instance 4, Cease , I1B, CDU HIGH TEMPERATURE
[10-02-25 01:15:38.586] O_RBS_Status.
All the fans in the cabinet are working. I have replaced the DTRU and CDU with known working units and still I get this alarm. Can anyone tell me if they have had this experience or where the temp sensor for this sector is located/

please I would like to know the factors that damage the flash card for RBS 22X6 and what is her duration of the life Thanks

Fault Name: TX high temperature
Related faults: SO TRXC I2A:11 – TX high temperature
SO TRXC I2A:25 – TX max power restricted
AO TX I1B:27 – TX max power restricted
Description: The temperature of the PA transistors is supervised. At maximum component temperature, faults SO TRXC I2A:11 and SO TRXC I2A:25 are raised on TRXC and maximum TX output power is reduced by 2 dB.
If the temperature is still over maximum component limit after 2 minutes, the maximum output power is reduced by another 2 dB.
If the temperature is still over maximum component limit after 2 minutes more, the transmitter is automatically shut down and faults AO TX I1B:12 and AO TX I1B:27 are raised.
The fault stays active until temperature stays below the limit for 5 minutes. The TX is then enabled and maximum output power is progressively increased.
Possible reasons: Climate system failure – dTRU dummies missing – high temperature outside the cabinet

how I can find the complet schmatic and block diagram of Ericsson rbs for complet units.

[jonah]

can anyone assist me with schematics on the ericsson rbs 2216 components, achitecture and configuration.
plz forward files to enekaro@yahoo.com

thanks

Dear Friends
Could you plz help me!!!
Can i put 2RBS per sector (Ericsson 2206, band 900)? Is it posible to synchronize them?
Present logical configuration is 3,3,3 (XRANGE and TCC activated) phisical is 12,12,12 i want to increse it to 4,4,4 means Phizical 24,24,24. hoping channel wre yousing (18TCH frequency)
Thx
Amex

i want know eveythin about rbs installation, radio configuration and site commissioninng

[Mocha]

Hi Arjun, the problem either from the antenna-connctors-feeder problem or from the BSC parameters changed.
check all the antenna system (vswr), then check the parameters in BSC.

Dear Amex, could u plz specify the problem?

[Amex]

HI Mocha!!
The problem is high congestion cause of high traffic on the site. Siteis serving huge area, taking traffic from 30 to 60km. XRANGE and TCC is activated for all 3 sectors. phisical configuration is 12,12,12 means rbs per sector. as we know if TCC and XRANGE is activated we /congiguration to 4 means logical config is 3 know. I want to add one more rbs per sector and phisical configuraion will be 24,24,24. (18TCH channels in hopping we are using. Logical i want to increase it from 3 to 5. But i’m not sure of synchronization of 2 rbs per sector. if you have some suggestion plz share. thx
Regards
Amex
