ABSTRACT:
The output signal level of a data node connected with a headend for use in a two-way cable communication network is monitored and adjusted at the node so that the signals received at the headend from all of the nodes in the network are substantially at the same level. The node terminal signal, which includes information identifying the address of the node, is initially transmitted from the node at a minimum level and is thereafter incrementally increased until a correct return signal is detected at the node, thereby indicating that the signal transmitted from that node is at a sufficient level to achieve the desired signal level equalization at the headend.
