Hi chandan debnath
Use two cells in first RBS 2206 with tie values 0,1,2,3,4,5 in cell A and 6,7,8,9,10,11 in cell B.
Use third cell in second RBS 2206 at tie value 0,1,2,3,4,5.
You will require 9 DTRUs in all.
Now just defined the required tie values from OMCR as per you configuration.
As per your requirment following tie values will be used..
cell A 0,1,2,3
cell B 6,7,8,9,10
cell C 0,1,2,3,4,5
