Hi Mr.Praveen ,
With 7 Erl , 280 simultaneous user is not possible. 280 is the maximum number of
connection that the system can provide based on the assumption that the average utilization(not
average capacity)of one user is 0.025 Erl.This value is not constant.It will vary for
different operator
I am not telling that with 35 Channels supports only 35 connection.But 35 channels
can support only 35 simultaneous Calls.
Please tell me how many simultaneous calls your system can support with two TRX ?
