Abstract: The apparatus protects a communication system from an overvoltage due to lightening and other voltage surges. The apparatus includes: lines (L1,L2) (T1,T2) and a ground line (G) formed on a printed circuit board (10); varistors (11,12) connected to a gas glow discharge tube (2) and connected between the lines (L1,L2) and the ground line (G); coil resistors (13,23), with one end of them being connected to the lines (L1,L2), and with the other end of them being wound around variable connection bars (12, 22) of an anisotropic shape memorizing alloy; and the variable connection bars (12,22) and ariable terminals (12a,22a) being connected through the lines (T1,T2) to the ground (G).
