Can anyone help me on how to clear the alarm “WCDMA cell out of use” and “Failure in WCDMA WBTS O&M Connection”? I’ve got too many alarms like these everyday in RNC.
Thanks for future replies.3rd March 2008 at 21:11 #51308taxxGuest
By the way this is NOKIA RAN(Node B and RNC).4th March 2008 at 06:32 #51309ex_Nokia_engineerGuest
Sounds like there’s problem on Iub transmission. Or, it can also some problem on those BTSs to which the alarm is pointing to. You can check the those BTSs with BTS Manager. Check also AXC.1st June 2008 at 14:17 #51310FISGuest
As I know,.
For WCDMA out of use, u try to delete some ajc neightbour.
For 7750 failure WBTS and O&M link failure, you try to re create DCN by ZQMF,ZQRN,ZQKC for RAS 5.2.Thus certainly your vp, vc is cross connected right1st June 2008 at 14:24 #51311FISGuest
Any body can help me to solve alarm 3267 at RNC,.AAL type 2 rejection level exceed for AAL type 2 path.
Many thank’s before and appriciate before2nd June 2008 at 10:14 #51312ex_Nokia_engineerGuest
If alarms “WCDMA cell out of use” and “Failure in WCDMA WBTS O&M Connection” occurs for site which has been working previously, it’s for sure some problem with Iub tranmssion or some problem with BTS itself. It has nothing to do with neigbour cells or DCN config in RNC.
Alarm 3267 can indicate if some AAL2 path has some capacity bottleneck; either all CIDs is reserved or AAL2 bw is not available. Use e.g. RNC’s statistics (Measurement 550, AAL2 path CAC resource) to find out this. Or you can use EPUTIL service terminal extension of command L to display load of endpoints (cps usage, cid usage).
I hope this helps.28th July 2009 at 12:16 #51313jazzGuest
We’ve encountered this problem – failure in wcdma wbts o&m connection. We’ve check all the parameters which happened to be all correct. I suggest you to perform BER testing of E1 link/s if all values conform with RNC and aggregator.30th July 2009 at 18:15 #51314Ruby SimmonsGuest
Can someone please shed some light on trouble shooting the Node B alarm 3101 Internal Failure in SAAL Stack? Thanks31st July 2009 at 12:09 #51315jazzGuest
3101—There has occured a failure in the SAAL stack, which transfers
signalling data. The signalling message transfer via signalling
link in question is not possible and signalling messages which have
already been sent to the signalling link might have been lost.
The system has changed the state of the signalling link to
OUT-OF-SERVICE and it is not possible to perform changeover to
another, replacing link. The system sets automatically the defected
signalling link back to the IN-SERVICE state when the SAAL
resources are in order again.
There is also a possibility that defective module. try to replace the transmission module. Check also the cross connection betwwen RNC and aggregator if properly defined.1st August 2009 at 05:15 #51316msaGuest
can u explain to me the process to create O&M connection (DCN)11th October 2010 at 14:30 #51317jolaGuest
could you please tell me how to calculate AAL2 path capacity for an 3G node B?17th January 2011 at 07:22 #51318CPGuest
could u pls tell me, Why we use the service terminal?6th April 2011 at 13:21 #51319viruGuest
“FAILURE IN WCDMA WBTS O&M CONNECTION
-7750”— What’s d meaning of this alarm and how we can remove this alarm….pls suggest Thanks…..6th April 2011 at 14:44 #51320SemirGuest
I am trying to figure out the voice capacity and consumption differences between a BTS and a nodeB:
For similar erlang (say 20, 40 and 80), similar frequency and coverage, what would be the energy consumption difference between a 2G BTS and a nodeB. (# of TRX can be variable)
Thank you!19th September 2011 at 00:32 #51321Sherif RNCGuest
this my mail for answer all your question:
msa, follow the below step, but becarfull when use the below commend’s
ZQKC:OMU,0&&1 and then enter
this commend will ask you put TRS IP like that (#:#:#:#) after that enter
and then the commend will ask you IFFE IP (#:#:#:#)
and then enter
and then you should write LOG and then ; and then enter
