Abstract

PURPOSE:To reduce the number of digital time division multiple circuits, by providing with a time division jumper circuit and plural digital trunk circuits, and processing the circuit information of various kinds. CONSTITUTION:A signal of 32 time slots on the signal highway 102 from the time division switch 101 is split to each kind of signal by the time division jumper circuit 107, the split signals are connected so as to correspond to the digital trunk circuits 104-106, and the digital trunk circuits 104-106 are able to process an MF receiving signal, an MF transmitting signal and a PB receiving signal, respectively. Accordingly, since it is enough to provide only one signal highway 102 between the time division switch 101 and the digital trunk unit 103, the number of circuits can be reduced.
