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

Using the receive line monitor mode and the hardware tristate function of transmit lines
XL1/2, the FALC56 now supports applications connecting two devices to one receive
