Abstract
In a transmission system comprising a plurality of data transmission circuits connected through a transmission line to form a loop, a local transmission signal is transmitted from a selected one of the data transmission circuits to the other data transmission circuits through the transmission line to be returned back to the selected data transmission circuit. The selected data transmission circuit interrupts the local transmission signal by detecting an identification signal preassigned to the selected data transmission circuit in a signal selecting circuit and by putting a switch circuit into an off-state during the local transmission signal sent from the selected data transmission circuit.
