How to handle CELL LOGICAL CHANNEL AVAILABILITY SUPERVISION alarm in Ericsson?

does anyone know how to clear this alarm? i tried with commands
RXBLI:MO=RXSTG-402,FORCE;
RXESE:MO=RXSTG-402;
RXESI:MO=RXSTG-402;
RXBLE:MO=RXSTG-402;
and it doesnt work. i also tried block unblock cell, restart rru. i want to skip restarting bbu, so is there any other solution?

Hi, @salebgd, check the output RXCDP:MO=RXSTG-402;, if all is in CONFIG then just set correct value with RLSLC command.

Hi, @salebgd!
Have you ALEX Library for GSM? Use the OPI “CELL LOGICAL CHANNEL AVAILABILITY SUPERVISION”. There are many steps for checking…

Hi!

INSUFFICIENT TX EQUIPMENT
Insufficient managed objects of class TX, with suitable capabilities are available within this TG to meet the cell requirement at the time of configuration. If more TX equipment has become available since configuration was started the cell must be halted and activated to include these TXs in the configuration.

INSUFFICIENT EGPRS EQUIPMENT
Insufficient managed objects of class TRX or IS, with suitable EGPRS capabilities are available within this TG to meet the cell requirements.

Where are TS, TX, RX?

I suspect something is locked, failed or misconfigured from RBS side. Check alarms/states on the node st trx, st rru, alt.

There is something wrong with trx 1&2 in sector PET3. Is it STG-637? How problem was start?

print sdir command


looks all fine


yes its 637, i restarted bbu, and now is fine. we have too many this alarms i n network, dont know root cause

Is it happens after power or TN failure? In this case try to set

RXMSC:MO=RXSTG-5,CONFMD=FASTREC;

Check logs lgaevgmr, what comes before this issue.

may be ‘sleep mode’ (TX, cell) are working. Check it.

i tried this fastrec, but again i have this alarm, and now is one trx down, CELL LOGICAL CHANNEL AVAILABILITY SUPERVISION CELL SCTYPE CHTYPE CHRATE SPV BG_PET3 TCH FR 1 END. Alarm showed at 19.54h and i dont have anything before that in log .

We are getting mixed signals here in rxmsp print everything is working in st trx print trx was disabled, was the print done right after rru restart, cuz it takes some time for cells to get back. Also make RLSLP print. Mybe just someone changed alarm thresholds or config like setting off VAMOS.

rxmsp was printed after bbu reset, and st rtx after alarm appeared
now again both trx doesnt work

Can you share this output for problematic STG when alarm is active, pls:

RXMFP:MO=RXSTG-637,SUBORD,FAULTY;
or if above fail
RXMFP:MO=RXSTG-637,FAULTY;
