When a call is made to the terminal 31 accommodated in No. 2, the exchange 10
Selects routes 1, 2 and 3 as the lines to be selected to the accommodating exchange 12 of the other subscriber by the selection signal from the terminal 30. The exchange 10 refers to the allowable line utilization rate table and the actual line utilization rate table, and after selecting the route, determines the route to the exchange 12 according to a predetermined selection order.
