Hi.
I am not familiar with Nokia equip but for such a wide spread problem start by looking at the common elements (BSC hardware) among the 20 cells.
Look also at the hardware KPIs for the BSC (CPUs etc) and it would be good if you gave us more details such as: Is the problem limited to a certain time of the day? etc
