トーキ送出の実現が要望されている。(2) Background of the technology In recent years, telephone exchange technology has shifted to digital switching technology, and the development of digital exchanges using time-sharing switchers has become active. Generally, in exchanges, there may be cases where it is necessary to restrict subscriber calls due to abnormal congestion or equipment failure in the event of a disaster. For this reason, digital exchanges are also equipped with a calling restriction function, but even in the case of striped primary restrictions that result in silence for subscribers, calling restriction can be used as an effective means to provide better services. There is a desire to realize the transmission of time talkies.
