my name is Akshay not Arun
anyway,i think you got it perfectly right.
but i want to stress when offered traffic is more than 99Erl say 103 ERLANGS with GOS=10%. now from erlangB table that require 99 channels.
but think how 99 channels can support 103 erlangs.
explore an appropriate reason.
Suppose holding time is 1hr
so Q=max 99
I=99*3600/3600 =99erl,and from erlangB table 103erl.how? try to find out.
