a little additional information..
There are both E-GSM and P-GSM in BBH active cells. The strange is that there are cells with BBH activated, but there is no this problems as in the cells without hopping.
What do you think about timer T3101. Is there relation between our problem and the value of this timer. He is equal to 3sec. for all cell.
The HSN’s are from 1 to 63 and there is no MAIOs…
