For short-haul applications like shown in
switched into receive line monitoring mode (LIM0.RLM = 1). One device is used as a
short-haul receiver while the other is used as a short-haul monitor. In this mode the
receiver sensitivity is increased to detect an incoming signal of -20 dB resistive
attenuation. The required resistor values are given in
