Hi Vijay
Here is the calculation:
BHCA = BHT * 3600 / MHT
where
BHT = Busy Hour Traffic in Erlang
MHT = Mean Holding Time in second
BHT = NSUB * C
where
NSUB = number of subscribers
C = traffic in Erlang per subscriber
-> BHCA = NSUB * C * 3600 / MHT
Normally C = 0.025 Erl/sub
-> BHCA = 300000*0.025*3600/100
-> BHCA = 270000
