The utility model discloses a network signal processing circuit, and the circuit comprises: at least one transmission line which is provided with a first connection end and a second connection end; and at least two transient voltage suppressors, each of which is connected between a ground point and a node on the transmission line. The two transient voltage suppressors are in parallel connection, and a line, in which each transient voltage suppressor is located, is in series connection with a micro-resistor. According to the utility model, a line where the two transient voltage suppressors are in parallel connection is in series connection with the micro-resistor, thereby achieving that the two transient voltage suppressors in parallel connection carry out current dividing of an overlarge current in a lightning signal. During lightning protection, the circuit provided by the utility model can prevent a transient voltage suppressor, which is broken down at first, from being burned down by the overlarge current,
