Hello, seems like the aalpath for BA5 is running over a VC that is down in ATM network, probably transport problem in my opinion, a logical link which is down or some crossconection. between RBS-RNC

Korin_ro,
Do you think this could be due to the MSN ?

hi k_RF,

Sorry for answering so late. I cannot know which is the point or the equipment that generates the problem, but I think that (if transport configuration is OK on radio access equipment RBS and RNC), than the problem is on transmission path, it might be an ATM switch, or even more "physical" like a PDH route down, or SDH route down, some ATM configuration not OK, or some SDH link configuration not ok. Sorry, but I don't know how can I help you more because I don't know what the transmission path consists of, in the network you are troubleshooting. If your department doesn't configure but radio access equipment I would ask someone from transmission. On radio access equipment I had once a VC down becouse the external VCi configured was not the same as the VC, but I think this is very rare. Anyway if PDH route is up some ATMswich has the fault.

Continuity check at AAL2path should be same on both ends. Have encountered same before, if true/false both sides should be same.
