Abstract
The present trunk line exchange system is capable of coping with the busy hour calls without falling into congestion by executing re-distribution of the number of communication lines to the busy region from the quite region, which results in yielding efficient utilization of the communication lines. The system is also capable of avoiding the congestion of the exchange system, since it is not necessary to conduct a series of operations such as recalls/alternative line processing.
