Abstract

PURPOSE:To enable to increase or decrease the signal conversion circuit in response to signal traffic, by replacing the bus circuit into time sharing switch. CONSTITUTION:When the transmission request signal is given to the transmission and reception circuit 7, the transmission and reception circuit 7 requests the exchange signal to the transmitter, and when the exchange signal is received, it is transferred to the control circuit 10. The control circuit 10 identifies the opposing party according to the exchange signal, selects the signal conversion circuit 11 in vacancy, and controls the time sharing switch 9 to form the connection path of the transmission reception circuit 7 sharing switch 9 signal conversion circuit 11 time sharing switch 9 transmission and reception circuit 8.
