Abstract

PURPOSE:To realize a highly efficient multiplied transmission by sharing the specified channel within one frame for the transmission of several types of signals of the data other than those which are not required always when the time-division multiplied data transmission is performed between the data terminals. CONSTITUTION:One frame is composed hitherto of the frame synchronous signal, data-use channels D1-Dn, the order wire, the supervisory signal and three channels of the folded signals. However, one sharing channel X is now provided to be supervised at the receiver side using the repetitive signal of an optional specified pattern as the switch signal. And with reception of the switch signal, the receiver side performs switching to the corresponding circuit and then receives the signals transmitted through channel X. In the case of the order wire, the switch signal is sent to channel X via signal switching unit 11, interface circuit 2 and multiplied transmission circuit 3 and by the calling request given from telephone 13 of data terminal 1. The switch signal is then detected at the receiver side to carry out calling through channel X.
