An ISDN (Integrated Services Digital Network) interface circuit is provided which is coupled to a terminal device via a transmission line and a reception line, the transmission line being formed of a pair of first and second wires, and the reception line being formed of a pair of third and fourth wires. The ISDN interface circuit includes a first resistor and a second resistor connected in series between the first and second wires of the transmission line, and a third resistor and a fourth resistor connected in series between the third and fourth wires of the reception line. The ISDN interface circuit also includes a D.C. power source connected to one of a first node at which the first resistor and the second resistor are mutually connected and a second node at which the third resistor and the fourth resistor are mutually connected. One of the first node and the second node other than the above-mentioned one of the first node and the second node connected to the D.C. power source is grounded.
