Hi,

check your external GSM cell definition in RNC - do they have correct LAC, CID, BCCH, BSIC? Then check in 3g->2G nbr definitions are correct in the cell?

If that does not show any error, then you have to check the CS core - if all Iu and A interfaces are defined correctly? as well are links between MSCs and MSSs defined correctly? In this case you will have huge number of failures.
