PURPOSE:To accommodate various signal systems on the same highway multiplexly, by controlling a line signal device based on the information of a in-band line signal, in a digital multi-line signal controller. CONSTITUTION:Lines 11-14 are connected to corresponding trunk circuits 7-10 respectively, these lines are multiplexed at a multiplexer 6 and connected to a highway 5. A line signal devie 3 is provided on this highway 5 and controlled with a line controller 4. In this case, the information disabling the line signal device is supplied to a line not using the in-band signal in the line controller 4 to accommodate the signal in the same highway 5, independently whether the signal system of the lines 11-14 uses the in-band system or not. |
