摘要： An automatic facsimile signal analyzing system includes a switch unit, a service trunk, a signal identification trunk, a facsimile communication determination unit, and a control unit. The signal identification trunk restores a facsimile control signal from a modulated and encoded facsimile signal on the set speech path and performs collection of communication state information and detection of a start of facsimile communication on the basis of the restored facsimile control signal. The facsimile communication determination unit permits an operation of the signal identification trunk when the classification result from the service trunk represents a type other than the voice signal and analyzes the communication state information from the signal identification trunk. The control unit performs switching/connection control of the switch unit, connects the service trunk and the signal identification trunk, both of which are in an idle state, to the set speech path upon setting of the speech path, disconnects the service trunk from the speech path when the classification result is output, and disconnects the signal identification trunk from the set speech path when the classification result from the service trunk represents the voice signal and when a call corresponding to the set speech path is ended.

摘要： 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.
摘要翻译：目前的干线交换系统能够通过执行从相邻区域到繁忙区域的通信线路数量的再分配来应对繁忙的小时呼叫，而不会陷入拥塞，这导致通信线路的有效利用。该系统还能够避免交换系统的拥挤，因为不需要进行诸如召回/替代线路处理的一系列操作。
