A full duplex link for sending and receiving digital voice/data signals over a line pair and which incorporates a sample and hold circuit in the receiving portion of the link which is triggered by each change of state of the transmitted signal from the link so that transients resulting from such transmitted signals will not interfere with signals received by the link over the line pair.
