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
