Abstract
A transmission apparatus for use in a master station in a passive double-star communication network has a management unit and a measurement unit. The management unit automatically acquires information identifying slave stations in the network. The measurement unit measures the propagation delays of the slave stations after their identifying information has been acquired. The management unit manages control states related to delay control in the transmission apparatus as a whole, and issues commands to the measurement unit. The measurement unit manages the state of the delay-measurement operation for each slave station individually.
