Similar Problem i am also facing…TRU is going in fail mode, MO fault description is Permanent fault and Bus fault in few cases.
we observed this alarm in 2204 BTS and 2964 BTS aswell.
in 2204 BTS, we changed the BTS s/w from R25E to R22F and found that issue got resolved permanently ( haven’t repeated from 1-2 months)
But issue is repeating in 2964 cabinet.19th January 2016 at 08:20 #49450YUNUSGuest
I are facing an issue wherein CF ,TF is operational But RXOIS does not come up resulting in All trx to remain down.
Can you plz help.
No DIP Errors found,
This is happening when a site goes down, when it comes back One sector remains down.
We have recently Implemented ABIS over IP for this RBSC.9th May 2018 at 16:31 #49451Lalit pariharGuest
