Abstract
An exciting command is transmitted from a center of a CATV system to a plurality of terminals in a block at the same time for exciting circuits in each terminal. A command to request each of the terminals to send response data is transmitted from the center to the terminals in sequence after excitation of the circuits. In response to the command, each of the terminals sends response data to the center.
