Thnx 2112 for the question.
As per your example,say the order of preference is
then the BSC will send 1,3,& 4 cells as “No. of preferred cells” if NPC is set >=3 in BSC.But if it receives HO reject from MSC,it will impose a penalty on the candidate & go for “Int Cell” as per the list.
Do ask for any doubt
