Abstract
In a data communication system having a network composed of a central facility, a plurality of relay units, and a plurality of terminal units, traffic information, which may contain information about a number of calls and a total amount of communication time occurred with respect to each relay unit over the predetermined interval, is sent from the relay units to a communication control unit. A ROM stores a threshold value for each relay unit and comparison is made to compare the received traffic information with the corresponding threshold value. Then, the is determined whether the subject relay unit is in a high-load condition. If so, relay units and terminal units that are scheduled to call the high-load relay unit are detected so that those units bypass the high-load relay unit.
