PURPOSE:To enable an information exchange using facsimile at optional time by arranging a device group wherein a 4W communication circuit and a 2W communication circuit (facsimile equipment) are connected physically by a hybrid transformer for 2W-4W conversion. CONSTITUTION:The output signal of the 4W communication circuit 1 is inputted to the 4W input terminal 7 of the hybrid transformer 2 for 2W-4W conversion through a signal transmission line (output side) 4, outputted from the 2W input/ output terminal 9, and inputted to the facsimile equipment 3 through a 2W signal line 6. The output signal of the equipment 3, on the other hand, is inputted to the transformer 2 from the terminal 9 through the 2W signal line 6, outputted from the 4W output terminal 8, and inputted to the circuit 1 through the signal transmission line (input side) 5, so that information can be interchanged at any time. The information exchange using facsimile is possible at optional time. |
