Abstract

PURPOSE:To prevent an increase of load to a common control device in the event of abnormal congestion of a trunk incoming call, by giving the information to a necessary incoming trunk from a device for detecting a congestion state, when a congestion state has occurred. CONSTITUTION:When a call processing congestion state of a common control device CC is detected by the congestion detection device HTD, the congestion detection device HTD activates the trunk relay control device TRC, and controls a relay for incoming call processing of a necessary incoming trunk which has been connected to the switch frame SW. As a result, even when incoming is made to the incoming trunk ICT, activation to the common control device CC is stopped, and a service sound is sent out from the sound source TN. SUB in the figure is an extension telephone set.
