Abstract: A terminal connector or plug protector is selectively configurable for coupling or coupling and protecting an electronic communication circuit to a communication line. The plug protector has a housing and a circuit board which is received in the housing. The circuit board has thereon a circuit which includes a plurality of circuit elements removably received in the circuit board. The circuit is coupled to the communication circuit and to the communication line with the circuit elements coupled therebetween. The circuit elements are selected from among a plurality of circuit element types, i.e., jumper wires, solid state voltage suppressors, and fuses, to configure the plug protector for the selected coupling or coupling and protecting.
