Abstract

PURPOSE:To prevent the lowering in information transfer efficiency and the production of missing of a part of transferred information, by measuring the transmission quality of communication line and comparing it with a reference value. CONSTITUTION:A transmission error production rate is always measured with a transmssion quality measuring device 6 provided on each communication circuit, and if the producton rate alpha exceeds the transmission quality reference value alpha1, the use of new call of communication line 5-1 is inhibited, and if it exceeds the reference value alpha2 further, the line 5-1 compulsively cuts off the call during communication, and if the state exceeds the reference value alpha2 for a prescribed time limit T2 or more, the line 5-1 is disconnected from a packet exchanger. Thus, according to the degree of deterioration of error rate alpha of the line 5-1, the call applied to the line 5-1 is controlled, allowing to reduce the lowering in the overall processing ability of the packet exchange system and the missing of transferred information.
