The paper discusses the options for building a device for making failures in the electrical communication cable. Using the analytical hierarchy method, it is reasonable to use for its implementation: contact relays - to simulate a break, variable resistors with servo drives - to simulate the asymmetry of the wires, multi-position switches with stepper motors - to introduce faults “insulation failure between two wires of different pairs” and “violation insulation to earth ground”. The optimal choice was made according to the five most frequently used criteria: cost, weight and dimensions, efficiency (speed of fault simulation), power consumption in case of faults and versatility of use.
